Field Report: Let’s build a super simple antenna on-site and activate this park!

24 Comments

Until 2016, I had never purchased a commercial field antenna; I built all the ones I had ever used.

These days, I take a number of commercial antennas to the field and use them in my real-time videos and I really enjoy deploying and using them. My buddy Eric (WD8RIF) reminded me, though, that I hadn’t actually used a homebrew antenna in ages. He was right!

You see, while I believe commercial field antennas can be incredibly durable and compact, it’s important to note that antennas are one of the easiest components of an amateur radio system to build yourself. They require only the most simple of tools and are very affordable. And the best part? They can perform as well as those that are available commercially.

I also get a great deal of pleasure out of building things.

A simple goal

I’ve mentioned in previous posts that I often set a little goal that runs in the back of my mind for each park or summit activation I make.

On Monday, June 14, 2021, I made a simple goal: buy my antenna wire en route to Lake James State Park, build the antenna on site, and complete a valid Parks On The Air (POTA) activation.

A very simple antenna

I also decided to employ my Xiegu X5105 since 1.) it’s one of the most affordable general coverage QRP transceivers I own and 2.) it has a built-in antenna tuner (ATU).

One of the cool things about having an ATU is that, if it has the matching range, you can allow it to do the “heavy lifting” in terms of matching impedance.

Although I’d never put the X5105 to the test, I suspected its internal ATU would have the matching range to forgo building a 4:1 or 9:1 transformer and simply pair it directly with a random wire.

All I would need was a 28.5 foot length of wire for a radiator, at least a 17 foot length for a counterpoise, and a BNC to binding post adapter.

The antenna would benefit from multiple 17′ counterpoises, but I really wanted to keep this setup dead simple to prove that anyone can build an effective field antenna with a very minimum amount of components.

Even though I have plenty of wire lying around the house to build this simple antenna, I wanted to pretend I had none to prove that any wire would work.

And to add just a wee bit more challenge, I also limited myself to shopping for antenna wire between my home and the park without making a serious detour from my route. That really limited my options because there isn’t much in terms of commercial areas between me and Lake James State Park.

The wire

As I left the QTH, I decided that the best spot to shop was a Walmart in Marion, NC. It would only be a four minute round-trip detour at most.  I had a hunch that Walmart would even have speaker wire which would be ideal for this application.

In my head, I imagined I would have at least three or four choices in speaker wire (various gauges and lengths), but turns out I had a difficult time finding some at Walmart. We live in such a Bluetooth world, I suppose there isn’t much demand for it these days. A store associate helped me find the only speaker wire they had which was basically a 100 foot roll of the “premium” stuff for $17 US.

While I would like to have paid a fraction of that, in the end it’s not a bad price because once you separate the two conductors, you have double the amount of wire: 200 feet.

Although the frugal guy in me cringed, I bit the bullet and purchased their speaker wire. To be clear, though, I could have found another source of wire in that Walmart, but I preferred speaker wire for this application. And $17 to (hopefully!) prove a point? That’s a deal! 🙂

Lake James State Park (K-2739)

Once I arrived on site, I found a picnic site I’d used before with some tall trees around it.

Here’s how I prepared the antenna:

First, I cut 28.5 feet of the speaker wire from the roll and split the paired wires so that I’d have two full 28.5 foot lengths.

Next, I stripped the ends of the wire and attached banana jacks I found in my junk drawer. Although these aren’t necessary as the binding post adapter can pair directly with the wire, I though it might make for a cleaner install. In the end, though, I wasn’t pleased with the connection to the radiator, so dispensed with one of the banana jacks on site, and later dispensed with the other one as well. The connection is actually stronger without the banana jacks.

I then deployed the 28.5 radiator with my arborist throw line, and laid the other 28.5 half on the ground (the ground of this antenna would pair with the black binding post, the radiator with the red post).  I only needed 17 feet of counterpoise, but once it couples with the ground, I don’t think any extra length makes a difference (although less than 17 feet likely would).

The antenna was essentially set up as a vertical random wire with one counterpoise.

I then plugged the BNC binding post adapter into the rig, hit the ATU button, and was on the air.

It’s that simple!

My new speaker wire antenna in all its glory.

Gear:

On The Air

I’ll admit: I was a bit nervous putting this antenna on the air. Although I felt the X5105 ATU *should* match this antenna, I had no idea if it actually would.

Fortunately? It did.

At this point, if you don’t want any spoilers, I suggest you watch my real-time, real-life, no-edit, no-ad, video of the entire activation (including buying and building the antenna!).

Click here to watch the video.

Otherwise, scroll for my activation summary…

I was very pleased that the X5105 found a match on the 40 meter band.

I started calling CQ in CW and validated my activation by logging 10 stations in 13 minutes.

Honestly: it doesn’t get much better than this.

I logged three more stations on 40 meters CW, then moved up to the 30 meter band where the X5105 easily found a match.

I worked one station on 30 meters before heading back down to the 40 meter band to do a little SSB. I logged three SSB stations in five minutes.

Mission accomplished!

In the end, I logged a total of 17 stations including a P2P with K4NYM.

Not bad at all for speaker wire!

After the activation, I tested the X5105 ATU by trying to find matches on other bands–I was able to find great matches from 60 meters to 6 meters. Most impressive!

X5105 battery

You might recall that I attempted to deplete my X5105 internal battery at my last (rather long) activation of Lake Norman State Park.  I wasn’t able to deplete the battery at that activation, but I finally did at this one.

All I can say is that I’m incredibly impressed with the X5105 internal battery.  This was my fourth activation from one initial charge on May 16.  The battery lasted for 20 minutes, taking me well beyond the 10 contacts needed to validate this park. I’ll now consider taking the X5105 on a multiple SOTA summit run!

Short Hike

Even thought the heat was intense and the humidity even more intense, I decided to take in a 2 mile hike post-activation. I snapped a few shots along the way.

This is the Christmas Fern which derives its name from a few characteristics: its resilience to early season snows maintaining a dark green color beyond Christmas, and because folks believe its leaves are shaped like Santa’s boots or even Santa on his sleigh.

Improvements

I’ll plan to add more counterpoises to the speaker wire antenna as I know this will only help efficiency.

In addition, I’ll plan to build even more antennas with this roll of speaker wire. If you have some suggestions, feel free to comment!

Thank you for reading this field report!

Cheers,

POTA Field Report: Attempting to deplete the Xiegu X5105 internal battery at Lake Norman

7 Comments

Each time I head to a park or summit, I have a goal in mind.

With summits, it’s getting to the summit and activating it because, sometimes, that can be a challenge in and of itself. I’m not exactly Sir Edmund Hillary, so I’m happy when I make it to the top of any summit!

Parks, however, offer me the chance to experiment with transceiver/antenna combos, test gear, and explore hikes. Parks tend to be more accessible and spacious than summits and even have shelter options if weather is questionable.

I don’t even attempt afternoon summit activations if they require a decent hike and there’s a good chance of pop-up thunder storms.

On Monday, June 7, 2021, it was hot and incredibly humid in the Piedmont of North Carolina. That early afternoon, little patches of showers were passing through the region delivering brief, isolated downpours.

The weather forecast also predicted a high likelihood of thunderstorms that afternoon. (Turns out, they were correct.)

Those were not conditions for a SOTA activation, rather, I decided to pick out a park I knew could offer up some shelter options. Lake Norman was an obvious choice–there’s a very nice covered area at their visitor’s center and also two large picnic shelters at the other side of the park. Lake Norman it was!

Goal

I drove to Lake Norman State Park with one goal in mind: deplete the Xiegu X5105 internal battery. I had assumed the battery would only power the X5105 for perhaps two activations on one charge.

Boy, was I wrong.

I charged the X5105 before this activation on May 17, then I completed this short activation on May 18. I never expected the battery to keep going, but it did.

Now three full weeks later, I decided I would deplete the battery at Lake Norman because that afternoon I had a decent amount of time to play radio in the field. In my head, I was prepared to squeeze perhaps 30-45 minutes more air time out of that one May 16 battery charge.

Lake Norman (K-2740)

I arrived at Lake Norman State Park and scouted out a site. Fortunately–it being a Monday in the early afternoon–it wasn’t busy and all three shelters were available.

I chose to set up at a shelter at the far end of the main picnic area.

Gear:

The humidity was so thick that day,  I was sweating just walking around the site. I noticed in my activation video (see below), I was breathing as hard as I would hiking to a summit even though I was just tooling around the picnic shelter.

I had no doubt in my mind that if a thunderstorm developed, it would be a doozie! (I was right about that, too–keep reading.)

On The Air

I paired the Xiegu X5105 with my Chameleon MPAS 2.0 mainly because I wanted to see how easily the X5105 ATU could match this multi-band vertical. Turns out? Quite easily.

I expected the X5105’s battery to deplete to the point that I would need to use an external power source to complete the activation, so I connected my QRP Ranger battery pack, but didn’t turn it on. I knew that when the radio died, I could flip the QRP Ranger’s power switch and perhaps only lose a few seconds of air time.

I hopped on the air and started calling CQ. I planned to operate the X5105 until the internal battery died, then (if needed) continue operating with the QRP Ranger until I logged my 10 contacts for a valid activation. Post activation, I planned to hike one of the Lake Norman loop trails.

Normally, I would mention the number of contacts I made perhaps noting the bands that were most productive. Instead, if you’d like to experience this activation with me, you might consider watching the activation video.

Video

Here’s my real-time, real-life, no edit video of the entire activation including my full set up.  My summary of the activation follows–keep scrolling if you’re open to a spoiler.

Please note that this is the longest video I’ve ever published, so don’t feel any pressure to watch it in its entiretity:

Impressed

Let’s just say that the X5105 sold me.

The activation was incredibly fun and I logged 20 stations (18 CW and 2 phone) from Alaska to Spain with my 5 watts and the MPAS 2.0 vertical.  Propagation conditions were only “meh” but since I had the time to play radio longer, I was able to take advantages of little openings as they happened.

X5105 Battery

The X5105 won.

I simply gave up on trying to deplete the internal battery because I was running out of time to fit the activation and a much needed hike that afternoon before thunderstorms moved in.

I operated over 90 minutes with constant CQ calls and the battery never made it below 10.2 volts.

A most welcome surprise.

No mic, no problem!

During the activation, I remembered that I had been asked by readers and viewers to include more SSB work.

Problem was, I left my X5105 mic at the QTH (nearly 2 hours away by car).

I remembered though that, like the Elecraft KX2, the X5105 has a built-in microphone.

I decided to give that mic a trial by fire and, by golly, it worked!

Not only did it work, but it worked well.

The X5105? A keeper.

It was at Lake Norman that day, I decided the X5105 was a keeper.

That evening, I reached out to Radioddity–who lent this X5105 to me–and offered to pay full retail price for it either in cash or via ad credit

Since Radioddity is a sponsor on my other radio site–the SWLing Post–we decided that, since their ad was coming up for renewal soon, I would simply extend their ad time an equivalent amount of months as the full value of the X5105 ($550 US). This saved them from having to cut a check in two months.  Worked for both of us.

I have much, much more to say about the X5105 and will do so in an upcoming review.

In short, though? It’s not a perfect radio by any means, but I feel like it really hits a sweet spot for the QRP field operator.

I enjoy putting it on the air and it’s an incredibly capable little transceiver.

I’m very pleased to now put it in rotation with my other field radios. Look for it in future reports!

QSO Map

Here’s the QSO Map for this activation (click to enlarge):

Hike and dodgy weather

After packing up my gear, I walked over to a nearby trailhead and checked out the trail map. I was prepared to take a very long hike that afternoon despite the heat and humidity, but I also knew conditions were ripe for a thunderstorm.

I decided to take what appeared to be a fairly short loop trail along the lake. Looking at the map, I assumed the trail might be 1 mile or so long.

The hike is well-worn and well-marked, so there’s no getting lost here. That’s one of the reasons I didn’t bother looking at my GPS map or even consulting the trailhead map in detail.

Instead, I simply started hiking the Lake Shore Trail loop. It was gorgeous. Here are a few photos (click to enlarge):

The skies started getting dark, though, and I heard a little distant thunder.

I decided it might make sense to consult my phone for the weather map.

A line of thunderstorms had developed and they were sweeping toward me. Time to pick up the pace of hiking!

It was at this point I realized I had underestimated the length of this loop trail. Part of me was quite pleased that it was longer than I anticipated, but the part of me that didn’t want to be caught out in a t-storm wanted to get back to the car ASAP.

I checked another weather map a few minutes later.

I decided that jogging the rest of the trail made sense!

Turns out the 1 mile loop was something closer to 3 miles when I included the walk back to the car.

I did make it back to the car in time, though, right before the heavens opened.

It’s no exaggeration to say that I was sincerely concerned about the possibility of tornadoes in that storm front.

The skies were dark enough that streetlights turned on and the rain was incredibly heavy with strong wind gusts. I saw flash flooding and driving conditions were nearly impossible. I parked next to a brick building in the town of Catawba and waited for the strongest part of the storm to pass. I was also very grateful I wasn’t still on the trail by the lake!

Of course, the storm passed and I expected conditions to be a little drier behind that front, but I was wrong. I think the humidity level increased to 150%. Ha ha! No worries, though, as I was on my way to air conditioned space!

Thanks so much for reading this field report and stay safe out there!

73,

An amazing SOTA activation on Mount Pisgah (W4C/CM-011)

2 Comments

Here in the Asheville, NC area, there’s one mountain that almost anyone can recognize by sight: Mount Pisgah.

Mount Pisgah is prominent because not only is it one of the taller summits bordering the Asheville basin, but it’s also home to the WLOS TV tower and and a cluster of public service and amateur radio repeaters.

I’ve been eager to activate Mount Pisgah for Summits On The Air (SOTA). Along with Bearwallow Mountain, and Mount Mitchell, it’s one of the most popular SOTA summits in the Asheville area.

One reason for its popularity is because it’s so accessible. Not only is there a dedicated, large parking area at the main trailhead off of the Blue Ridge Parkway, but it’s also an easy hike from the excellent Pisgah Inn, restaurant, and camp grounds.

Being so accessible from the BRP, the Mount Pisgah trail also receives a heavy amount of foot traffic. Being locals, our family tends to skip this trail when we’re venturing along the BRP because it can be so congested at times.

Mount Pisgah (W4C/CM-011)

On Tuesday, June 1, 2021, Hazel and I decided to hit Mount Pisgah fairly early and avoid the crowds.

We arrived at the trailhead around 8:15 AM and there were very few cars there–a good sign indeed!

Hazel was chomping at the bit to start our hike!

The trail is only about 1.5 miles with a 700 foot elevation gain, so not strenuous.

It was blissfully quiet and we only passed two other groups of hikers on the way up.

I’ll admit that I was keeping an eye out for black bears, though. We saw bears very close to the trailhead entrance on the BRP that morning. I may have mentioned before that black bears are not something to be feared here in western North Carolina; they typically avoid people and your chances of being fatally injured by a black bear are incredibly slim–right there with being struck by lightening.Still, the black bears that wonder near populated spots like Pisgah along the parkway are often fed by tourists and lose their fear of humans. Not only that, but they even expect people to be food dispensers. Not good. As we say around here, “a fed bear is a dead bear” because feeding bears leads to aggressive behavior and the poor creature’s eventual euthanization.

But I digress!

Hazel and I reached the summit and were happy to find that we were alone. Pisgah’s summit can get very crowded as there really isn’t a lot of space–only a large viewing platform next to the massive tower.

When we arrived on site, the summit was surrounded in clouds.

I briefly considered operating from the viewing platform, but knew I would have to cope with a lot of curious hikers while trying to operate CW. Since I’m not a good multitasker, I decided to do what many SOTA activators do: carefully pass under the tower and find an activation spot on the other side of the summit.

Hazel and I found a small overgrown trail used primarily by those working on the tower. I deployed my station in a small clearing.

Gear:

For this activation, I chose my Elecraft KX2 and paired it with the Chameleon CHA MPAS Lite which has quickly become one of my favorite SOTA antennas.

I deployed the CHA MPAS Lite perhaps 15 feet away from my operating spot, in the middle of a spur trail. I was able to extend the 17′ vertical without touching any branches. I rolled out about 20-25′ of counterpoise wire along the ground.

After setting up, it dawned on me that I’d forgotten my clipboard.  No worries, though! I simply flipped over my GoRuck GR1 pack and used the back as an operating surface.

On The Air

Not only was this a summit activation, but also a park activation–indeed, a two-fer park activation at that! The summit of Mount Pisgah is in both Pisgah National Forest (K-4510) and Pisgah State Game Land (K-6937).

If I’m being honest here–since I’m not a “numbers guy” and don’t follow my activation counts closely each year–it’s very tempting not to announce or count this activation in both the SOTA and POTA programs since K-4510 and K-6937 aren’t rare entities. The main reason for this is because, back home, I end up doing double entry with my logs: loading them via the SOTA online log submission tool, then entering them in N3FJP or TQSL for submission to the POTA and WWFF programs. It can be very time-consuming doing this.

I am working on a way to “massage” the ADIF file data so that I can submit it to both programs with less effort.

But, of course, I announced the activation on both SOTAwatch and the POTA site. At the end of the day, I’ve never *not* announced a dual SOTA and POTA activation because I can’t help but think it might offer up the sites to a new POTA hunter. It’s worth the extra log entry later.

Another plus with activating a site in two programs is that you’ll likely be spotted in both thus increasing your odds of logging the necessary contacts to validate your activations.

Turns out, snagging valid activations that Tuesday morning was incredibly easy. And fun!

Fabulous conditions!

I started on 20 meters CW and logged fifteen stations in eighteen minutes.  The band was energized because not only did I easily work stations from France, Slovenia, and Spain in Europe, but also stations all over North America from the west coast to as close as the Ohio valley and into Canada.

I wanted to play a little SSB, so I moved to the phone portion of 20 meters and spotted myself on the SOTA network. I worked five stations in eight minutes. Fun!

Next, I moved up to the 17 meter band and stayed in SSB mode. I worked five more stations in nine minutes. Had I only activated this site in SSB on 20 and 17 meters, I could have obtained both a valid SOTA and POTA activation in 17 minutes.

Even though I knew I needed to pack up soon, I decided to hit the CW portion of 17 meters before signing off.  I started calling CQ and was rewarded with sixteen additional stations in eighteen minutes.

Phenomenal!

All in all, I logged 41 stations.

Here’s the QSO Map of my my contacts–green polylines are CW contacts, red are SSB (click to enlarge):

A welcome interruption!

If you watch my activation video, you’ll note that as I moved to the 17 meter band and started calling CQ, another hiker popped in and introduced himself.

Turns out it was Steve (WD4CFN).

As Steve was setting up his own SOTA activation on Mount Pisgah next to the observation deck, his wife, Patty, heard my voice off in the distance giving a signal report.

Steve and I had a quick chat and coordinated frequencies so we wouldn’t be on the same band at the same time and interfere with each other.

 

After finishing my activation, I stopped by the observation deck and spent some time with Steve and Patty as Steve finished his SOTA activation and packed up his gear.

Steve was also using an Elecraft KX2 and strapped his telescoping fiber glass mast to the side of the observation deck to support a wire antenna. Very effective!

Hazel and I hiked back to the trailhead with Steve and Patty. It was so much fun talking ham radio, QRP and SOTA with kindred spirits. What an amazing couple!

Steve and Patty were actually on a multi-day camping trip in WNC and planned to hit two more summits by end of day. In fact, I got back to the QTH *just* in time to work Steve (ground wave!) at his second summit of the day. It was fun hunting someone I had just spent time with on a summit!

Steve and Patty: Again, it was a pleasure to meet you both!

Video

Here’s my real-time, real-life video of the entire Mount Pisgah SOTA activation:

A memorable activation indeed

Hazel and I both needed a little trail time that Tuesday morning. Hiking to the summit in the low clouds, taking in the views, enjoying a stellar activation and then meeting new friends? It doesn’t get any better than this.

I’ll say that I do love the Elecraft KX2 and CHA MPAS Lite combo. It makes for a compact and effective SOTA pairing that can be deployed so quickly.

A couple months ago, I ordered a SOTAbeams Tactical Mini fiberglass telescoping pole. I plan to pair it with my QRPguys tri-bander kit antenna.

If I’m being honest, though, I find that the CHA MPAS Lite is so quick to deploy–like 2-3 minutes tops–I’ve yet to take the Tactical Mini and Tri-Bander to a summit.  No worries, though, as I will eventually deploy this pair on a summit. Admittedly, I need to work on my mast guying skills in advance–let’s just say that I’m still in that awkward stage of struggling to manage each guy line as I try to keep the Tacmini vertical during deployment. I welcome any tips!

DAY4: A SOTA Adventure To Remember (Conclusion)

3 Comments

I hope the first two parts of my SOTA journey with Mark, NK8Q, has been interesting reading. It is really tough to put into words what the trip meant to me. Back in November I had my left knee replaced, and was preparing myself to possibly not be able to enjoy the luxury of being able to walk, run, hike and backpack. I never would have dreamed by the time this SOTA journey started that I already would have walked a half marathon on the new knee, nor be able to hike up summits. I have been truly blessed to be able to continue to do the things I enjoy. SOTA and POTA over the past year has renewed my interest in the hobby.

After we left Stony Man Mountain, we headed to the campground we were staying at along Skyline Drive. We lucked out earlier in the day by randomly arriving around 11:45 a.m. at the campground and even though the sign said it was full, the park ranger said to wait 15 minutes because there could be some checkouts right at the cutoff. We waited it out and at noon the ranger confirmed we had a campsite! Perfect…after 2 days of staying in motels, I finally got to camp in my new tent.

Once settled in, I thought it would be a good evening to set up my antenna and operate a little “late shift” on POTA – Shenandoah National Park (K-0064). I was just a bit too far off the A.T. to make it a “twofer”.  This yielded 16 QSOs and then called it  a night.

The next morning was also the last day of our SOTA trip. I woke up after a pretty restless night due to the fact my old body cannot tolerate being so low to the ground. I believe the last time I slept in an actual tent was in 1981 in boot camp at Parris Island. I am now a hammock camper and it sure feels much better on the back. So, back to the story. After breakfast we packed up and drove to the first of two SOTA summits before heading home.

The first was Pinnacle Overlook (W4V/SH-005). The climb took an unexpected wrong turn from the parking lot but quickly rectified. The hike to the summit was fairly steep, but there was beautiful flowers and rock formations and the summit was aptly named The Pinnacle. What a beautiful view of the Shenandoah National Forest.

We saw several thru hikers on our hike both up and back down the mountain after the activation. Several were interested in our ham radio operations. I found a perfect spot to operate from right along the Appalachian Trail and off to my left I could look over and see the view. I had 20 QSO’s and the bands were in decent shape.

It was time to head back down to the parking lot and continue our journey to the next stop, Hog Back Overlook (W4V/SH-007). There wasn’t much of a view once we climbed to the top of Hog Back, but met more through hikers, including one lady who was wearing a hat from Boston Marathon. Her trail name was GiGi, which is her Grandma name, which is also my wife’s Grandma name. She decided at age 65 she was going to hike the entire A.T. and had already run the Boston Marathon, so this was a bucket list item for her. I told her hiking the entire A.T. is my goal in 2026 when I’m retired and was nice to know there are hikers in our age group that are still able to accomplish these things. We gave her some trail magic, and Mark and I continued on our way to the top of the summit. There wasn’t much besides an old building which may have been a ham radio shack at one time, and some towers but not much of a view. We did a fairly quick activation and I had 12 QSO’s before packing it up. (I almost thought I heard the sound of banjos playing up there.)

We made a couple of other stops along the Skyline Drive, one was for the tunnel that was built along the route, and another stop to see the scenery from the outlook. It was time for me to start heading back to Lancaster County, which was about a 4 to 5 hour drive and Mark had two other summits he wanted to visit. What I did not expect to see at the one stop to look at the views was a lady who was sitting along the rock fence painting. I asked her if I could take a picture of her holding the picture she was painting and she gladly agreed. It took her about an hour to paint it and was finishing up when I arrived. After I left I regretted not thinking to ask her if I could have purchased the picture!

I arrived home around 5:30 pm on that Sunday evening and was completely exhausted. Mark sent me a text and told me at his next summit he was on the trail and saw GiGi again.

Thankfully, I had taken Monday off for a vacation day because I was exhausted from all the traveling Mark and I had done in 4 days. In addition to the driving, we did a lot of walking to the summits and operating. It was an experience neither of us will ever forget. We are already starting to plot our plans for next year for another adventure.

I’d like to thank Mark for putting this trip together and plotting out which Summits to do on each day and the best way to navigate to each destination. The hikers on the trail were all wonderful, and some of them asked questions about what we were doing, especially when we had our fishing poles at the summit with no trees. I used the HAMRS program for the 4 days, and other than some operator error, the program worked flawlessly. I especially would like to thank Thomas Witherspoon for allowing me to share my story on QRPer. Tom is an awesome ham and we share many of the same interests for POTA or SOTA, and we both enjoy antenna experimenting and our passion for QRP operating. Thank you again Thomas for the opportunity to share my experience, and I hope you enjoyed my SOTA experience.

Pairing the Chameleon CHA LEFS with the Discovery TX-500 at Table Rock Fish Hatchery

8 Comments

Last time I visited Table Rock Fish Hatchery–this activation–it was a struggle to get the ten contacts I needed for a valid activation. Propagation was horrible that day, making it a proper struggle.

On Thursday, May 20, 2021, I thought I’d go back to the fish hatchery for another try! I really like the site: it’s open, has lots of trees, and the staff (and neighborhood dogs) are all very friendly.

My not-so-QRP diesel truck!

Thing is, as I drove to Table Rock, my buddy Mike informed me that propagation took a nose dive. Earlier in the day, it had been reasonably stable, but he noted that POTA activators were struggling in the afternoon and the propagation numbers were in the dumps.

There’s a beautiful little creek next to the picnic area.

My secret weapon: The Chameleon CHA LEFS

Shortly after I posted my “unboxing” video of the lab599 Discovery TX-500, Carl at Chameleon Antenna made a comment on my YouTube channel that he was going to send me their CHA LEFS (Lightweight End Fed Sloper) wire antenna since it’s resonant on 40, 20, 17, 15, 12 and 10 meters. In many ways, it’s ideally suited to pair with the TX-500 since this transceiver lacks an internal ATU. Side note: there is a cool project in the works called the DIY599 that adds a 60 watt amp and ATU to the TX-500 . 

I had only recently received the CHA LEFS and had not yet taken it to the field. Table Rock was the perfect opportunity.

When I know in advance that propagation is poor, I try to make my portable set up as efficient as possible, so that’s when I 1.) make sure I pull out a resonant wire antenna and 2.) use a wire antenna with longer radiators. The CHA LEFS fits both of these bills.

The CHA LEFS has a 63 foot radiator made of 20 gauge PTFE antenna KEVLAR wire. The winder has a large efficient transformer to match impedance, and there is an inline coil to make the most of the 63′ radiator. They also include 50′ of Micro 90 paracord.

 

Like all Chameleon antennas I’ve used, it’s built to military specs.

Table Rock Fish Hatchery (K-8012)

Table Rock is ideally-suited for a long-ish sloping wire antenna, too. The site has tall trees and open spaces that make stretching out the sloping radiator quite easy. Just watch those power lines!

The CHA LEFS takes longer to deploy that end-fed antennas with a feedpoint near the ground. I find it quicker to deploy, however, than dipoles.

I deployed the LEFS by first stretching out its radiator wire in the direction I planned to deploy it.

Next, I connected the coax feedline to the SO-239 on the LEFS winder and stretched it in the opposite direction of the radiator. Why do this? It helps keep the radiator and coax from twisting together as I raise the winder/feedpoint into the tree.

This is not a difficult antenna to deploy as one person. Of course, if you have a helper, it’ll go even faster (I’ve yet to convince Hazel to help me with antenna deployment).

I had launched the arborist line quite high into a tree at the picnic table where I planned to operate. I was able to elevate the LEFS feedpoint/winder about 47′ into the tree.

I used the supplied paracord to attach the radiator to a nearby branch. The end of the sloper was perhaps 6 feet off the ground (if memory serves).

Gear:

On The Air

Knowing how poor conditions were from real-life K8RAT observations, I didn’t expect to actually validate my activation by logging the required 10 contacts. As I stated in my activation video, I was fully prepared to walk away with three or four contacts–I didn’t have a few hours to burn on an activation. I was simply happy to play with a new antenna, the TX-500, hang with the local canine welcome committee and enjoy the fine weather.

First, I hopped on 40 meters and discovered the LEFS provided a perfect 1:1 match on 7063 kHz. Very promising!

Next, I started calling CQ and the Reverse Beacon Network functionality of the POTA spots page must have quickly auto-spotted me.

Within 13 minutes, I logged six contacts! I was impressed. Mike (K8RAT) was in that first six contacts and he later told me it was one of the strongest signals he’d ever heard from me at a POTA activation. He asked what I was using as an antenna that day and said, “it was working!”

Next, I moved to the 30 meter band and worked K8RAT again (a rarity on 30 meters!) along with four other stations.

I ran out of time, so called it quits with 11 stations logged.

I did not expect to not only walk away with a valid activation, but to have completed it in such short order.

QSO Map

Here’s the QSO Map of my contacts all made with 5 watts of power:

Video

Here’s my real-time, real-life, no-edit video of the entire activation. Next time I take the LEFS out, I’ll try to remember to include setting it up:

Loving the CHA LEFS!

Talk about good first impressions!

As Carl suggested, I’m going to keep the CHA LEFS tucked away along with my PackTenna EFHW in the Discovery TX-500 pack.

When conditions are poor, I’ll spend the modest amount of extra time deploying this fine antenna.

The only CHA LEFS criticism I noted–and it’s a minor one–is that the in-line trap/coil isn’t very low-profile and takes a little attention to make it fall in the right spot when reeling the antenna up post-activation. Seriously. A minor criticism and I’m guessing Chameleon has a reason for it being on the large size–likely for power handling reasons.

Field Day is coming up, and I think I’m going to make the CHA LEFS one of Team Baklava‘s main antennas (Team Baklava = my buddy N3CZ and me!).

As for the CHA LEFS, I highly recommend it!

Days 2 – 3: A SOTA Adventure To Remember (Part 2)

8 Comments

I would like to thank everyone for their positive and kind comments from my first part of the SOTA adventure with NK8Q. I have a slight correction to make, Cole Mountain was the first summit we did on Day 2. As you can see below in the pictures, there were no trees to hang our EFHW antennas, so we brought along our fishing poles. This generated a lot of interest from the A.T. thru hikers asking what we were doing. On particular hiker told us he’s seen others doing SOTA at summits throughout his journey from Georgia until that day. This was a fairly steep climb to get to, but the scenery was fantastic and well worth the walk. We offered trail magic to several of the hikers and we had very good conversation with them all.

Heading back down from the summit are a couple of other views we saw. There were some trees outside of the activation zone.

We packed up and started heading down the mountain to the parking lot around noon with the next destination Rocky Mountain (W4V/BR-001).

We drove almost 3 hours to get to this drive-up summit. The “S” turns and elevation changes were worth it though as there was so many spectacular views of the mountains. The last 4 or 5 miles was up a very steep gravel road that had me white knuckling until we got to the top. This was a site with several towers for different things and not a lot of view. I was able to get 10 QSO’s at the summit. I recall it was getting very warm that afternoon and I was not looking forward to the drive back down the mountain on the access road. I figured out how to do the manual shifting in my Tucson and Mark followed me down the hill. It was a non-issue and then we had a long drive to where we thought we would be able to camp on Skyline Drive.

I got my 4 SOTA QSO’s, time to relax.

When we finally got back onto paved roads and eventually into cell phone coverage briefly; we were hoping to find a place to get ice for the coolers and maybe a place to eat. Well, we found a gas station in the middle of nowhere with ice and a little store and they happened to be selling their own fried chicken and fries. When we got to the south end of Skyline Drive entrance, the sign showed all of the campgrounds were full. Since it was already getting dark, we made the decision to get on I-81 and head north and found a Super 8 Motel in Newmarket, VA for the night with the plan to get back to Skyline Drive at the Thornton Gap entrance. We got up early and looked for a gas station and a place to eat. Conveniently, Dunkin Donuts has a gas station as well (we didn’t realize that until after we got gas) but had a good breakfast sandwich each and I got a large coffee. I believe Mark is only the second person I’ve ever known who does not drink coffee. I believe my large cup was consumed before we got to Skyline Drive that morning, which I believe was about 18 miles.

First Summit of the day was Hazeltop Mountain (W4V/SH-004), which was south on Skyline Drive. The scenic outlooks were beautiful on the way to the summit.

Once we reached the summit, there was not much to see. I set up a few yards off the A.T. and made 15 contacts. The band conditions were pretty decent. This was my set up at this location.

Next stop – Hawksbill Mountain (W4V/SH-001).  It was just after 12 noon when we got to the parking area, and there was a good mile or so of steep uphill climbing. The reward at the top was worth the climb! I got another 20 QSO’s in the logbook at this summit.

This dial pointed to the many summits within view of Upper Hawksbill.

Final summit for the day was Stony Man Mountain (W4V/SH-002). This was another steep climb, but the reward was also a beautiful view.  I made 8 QSO’s and Mark and I shared the antenna and radio due to the limited space and all the people walking around at the summit.

I will continue with Part 3 of our journey to the Summits in Virginia in the next post. I hope I have half the writing skills that Tom Witherspoon has and that I was able to hold your interest in the SOTA journey that Mark and I did. I will wrap up the story with a Part 3. Thank you for taking the time to read this.

Day 1: A SOTA Adventure To Remember (Part 1)

6 Comments

First of all, thank you so much Thomas Witherspoon (K4SWL) for allowing me the space to tell my recent story from my trip to Virginia. I hope you find it interesting. I certainly do not have Tom’s writing skills so I’ll do my best.

A quick introduction. I was licensed in 1983, call KA3LUW, as a Novice mostly a CW operator. I upgraded in 1992 to Extra with the 20 WPM code. I was mostly interested in DX and around 1996 went through some life changes and became inactive for several years until about 2003 when my Dad (N3FWI – now SK) gave me his Kenwood TS 450 to sell. I put up a temporary antenna and discovered PSK31. That actually got me back into ham radio as Dad let me keep the radio. At that point I changed my Extra call from WY3X to KN3A. Over the years my interest is still chasing DX and contesting. In 2015, I was chasing the W1AW year long event for the ARRL Centennial so I could confirm as many states on as many bands and modes as possible. When 2016 started, my ham friend, Mark, K3MRK told me I should get involved with NPOTA (National Parks on the Air) which was also celebrating their 100th anniversary. I was just so burned out from ARRL the prior year that I did not get involved. My interest in the hobby also started to wane as well, as I got into fitness due to health issues.

Fast forward to 2020. Mark continued to praise the now POTA program and all the fun he was having with it. It seemed to be something I would also enjoy as I could walk, hike and exercise as well as discover portable operations. On March 14, 2020, Mark convinced me to do a POTA activation with him at the local Sam Lewis State Park (K-1418) near my QTH. It was very cold and windy but we had a successful activation and I was hooked. Since then I’ve done 75 activations from 9 unique parks in 3 states. To say I am hooked is an understatement!

I have another good friend Mark, NK8Q, who is an avid Summits on the Air activator and chaser (SOTA). Mark lives about 2.5 hours west of me, and last summer we met and activated two Summits together. The first was a drive up summit and the second one required a little bit of hiking to reach the summit. I like the idea of walking, hiking and backpacking so SOTA is also something I enjoyed doing last year.

Two years in a row K3MRK and I have tried to get to Dayton, only to have them cancel due to the pandemic. I had scheduled a week off of work and decided to keep the time off and contacted Mark – NK8Q about possibly doing a backpacking SOTA adventure.

We talked about different places we could go to activate, and ultimately we decided to do several 10 point summits along the Blue Ridge Parkway, Skyline Drive and along the Appalachian Trail. For me, this was going to be not only a SOTA activation, but in some instances the activation also counts for POTA.  We both left our homes early morning on May 20 and meet in Natural Bridge, VA and we would spend the next 4 days heading north, while activating different summits. We actually realized about 100 miles north of Natural Bridge that Mark and I were only about a mile apart heading south on I-81, so we took advantage of 146.52 simplex the rest of the way to our starting point and we used FM simplex driving from summit to summit.

We arrived at Natural Bridge just before 10:00 a.m. and Mark asked if I wanted to activate K-3972 (Natural Bridge National Park). Sure, why not, it would be fun to do a quick activation. We found a nice spot to set up the antenna and radio. My equipment for this journey was a Sotabeams Bandspringer Midi and my ICOM 705. I put 11 QSO’s into the log the short time we were there and was a nice warm-up for what was ahead.

After the quick POTA activation, we started heading to our first summit, which was Apple Orchard Mountain (W4V/RA-001). This was along the Blue Ridge Parkway and the views heading there were spectacular. Once at the summit we explored the area and then found our operating spots. I made 20 QSO’s and 3 S2S (summit to summit).

Second summit was Cole Mountain. The parking area was about 700 feet below the summit of 4,020 ft. Most of this climb was along a private road that goes up to several towers and they were cutting the grass. They waved as we walked up and were also very close to the Appalachian Trail (AT). Cole Mountain yielded 27 QSO’s in a very short period of time.

We hiked back to the parking lot and proceeded to our next summit of the day at Petites Gap Trailhead where we went to Highcock Knob (W4V/RA-014) where we hiked about 700 feet in just over a mile. This was a fairly rocky and difficult climb and being tired from other summits and the drive down first thing in the morning, it was nice to be the last summit of the day. The elevation at the peak is 3,073. Mark and I had some issues getting our antennas through the trees at this summit and wasted a lot of time. Once the issue was resolved, I made 8 QSO’s. Mark and I decided it was time to start heading back to the parking area and call it a day. Since we were on the Appalachian Trail, we met many thru hikers heading from Georgia to their final destinations in May. Every one of them were really nice and eager to find out what we were doing at the summits and we made sure we had “trail magic” as they call it on the A.T. We carried extra water and snacks, and they were always much appreciated by the hikers. Just before we got back to the car, we met up with a hiker from Minnesota who was hanging his bear bag in a tree and he was preparing to camp for the night. When Mark and I got back to the car I thought, here I am with a cooler full of ice cold beer, I bet this man would appreciate a beer or two. I went back and he couldn’t get to the car fast enough! If you are ever hiking on the A.T. make sure you bring some trail magic as well. In the picture below, Mark was using my rig and we were right at the summit.

We left and went looking for a place to camp for the night. There were no campsites available so we stayed in a very old motel that I was afraid was going to be full of bed bugs or something. We survived and day 2 of the SOTA adventure was ready to begin.

Enjoying a casual trailside activation with the Xiegu X5105 and PackTenna 9:1 Unun

Leave a comment

I love day hiking with radios.

When I pack all of my radio gear in a field kit that is compact enough to fit in a small day pack, it forces me to only take the essentials. This, in turn, makes for a quick deployment and pack-up.

I think this is one of the reasons I find Summits On The Air so appealing.

On Tuesday, May 18, 2021, I had a hankering to fit in a hike and, of course, play radio. I also wanted the option to fit in two activations, so needed a simple and short hike to minimize time.

Tuttle Educational State Forest (K-4861)

I decided to head to Tuttle Educational State Forest–one of my favorite accessible POTA sites–because their two mile loop trail was just what the doctor ordered. In fact, I knew exactly where I wanted to set up on the trail.

Tuttle is rarely busy–especially on a Tuesday afternoon.

I arrived on site and, as I was pulling my backpack out of the car, I was greeted by one of the Tuttle park rangers. He was incredibly nice and provided me with even more ideas of places to set up in the future along the trail and trail extensions. We must have chatted for 15-20 minutes–he had a number of questions about amateur radio and I never miss an opportunity to be an ambassador for both ham radio and POTA/WWFF.

Gear:

On The Air

The hike was amazing and, besides park rangers, I had the entire site to myself. About 1.5 miles into the hike, I found the spot I earmarked for this activation: a little open area with three wood benches on the side of the path.

This particular deployment reminded me how thankful I am that I discovered the Arborist Throw Line last year. I had the PackTenna deployed in three minutes.

It was so…effortless.

I decided to take the Xiegu X5105 out for another activation. Radioddity sent this to me on loan for a full evaluation and review. The previous day, I activated the Blue Ridge Parkway with the X5105.  I wanted to see how many activations I could accomplish off of one charge of the X5105’s internal battery, so after the BRP activation, I didn’t re-charge the battery.

As insurance at Tuttle, I brought along my trusty QRP Ranger LiFePo4 battery pack and hooked it up to the X5105. If the X5105’s internal battery died on me, it would be easy to simply turn on the QRP Ranger’s power switch and hop right back on the air.

I started one of my real-time, real-life activation videos (see below), then called CQ on 40 meters.

Maybe that quick antenna deployment was foreshadowing the activation, because in the span of 13 minutes, I logged 11 stations all on 40 meters.

I was very pleased to work P2P (Park To Park) contacts my friends Steve (KC5F) and Scott (KN3A). Thanks, guys, for hunting me!

Here’s my log:

I didn’t even move up to 30 or 20 meters after working the string of contacts on 40 meters because Tuttle is far from being a rare site and I wanted to fit in one more activation that afternoon.

The X5105’s internal battery easily powered the rig for the entire activation (perhaps a total time of 15 minutes). I suppose I’ll have to take it to yet another park on this same charge!

Packing up was nearly as quick as deployment. I owe thanks to one of my YouTube Channel subscribers for suggesting that I pack the Arborist Throw Line pouch by winding figure eight bundles of line on my hand (much like I do with antenna wire) and stuffing them in the pouch one bunch at a time. This saved me a lot of time.

While the portable throw line pouch isn’t as quick to pack as the throw line cube, this method made it a cinch!  I can’t find who originally made the suggestion, but I’m grateful–thank you!

Video

Here’s a link to the full activation video:

Photos

During my loop hike, I snapped a few photos (click to enlarge):


Well hello there, little fella’!

I’m most grateful to the late Ms. Tuttle for leaving this amazing park for all to enjoy. Her legacy protects this land for all future generations.

When you’re doing a park or summit activation, don’t forget to stop and take in a good dose of nature and the outdoors.

It does us all a world of good.

More X5105 thoughts

This second activation had me warming up a bit more to the X5105. I do like its size, and I think it’s a good rig for CW ops.

CW operation is very pleasant, actually, and keying feels natural. I was impressed that the battery held for a second activation, even though this was a very short one.

Again, I think the internal speaker audio leaves a bit to be desired–I dislike the audio splatter I hear at higher volumes–but for $550? It’s really hard to be critical.

During this activation, I still hadn’t learned how to program CW memory keying. A YouTube subscriber recently described the process and it seems overly cumbersome and much more complicated than it was in an earlier firmware version.  I’m going to contact Xiegu about this. Unless I’m missing something, it really holds the radio back from being pretty stellar on CW for the field op.

Readers, if you own the X5105 and can describe the best way to use CW memory keying, please comment with directions! I’d really appreciate it!

Thank you

Thank you once again for reading through this field report and perhaps watching the activation video.

I’d also like to thank the readers and subscribers who’ve recently supported me on Patreon and via PayPal. I am humbled and honored.

Thank you.

New radio day! A shakeout activation on the Blue Ridge Parkway.

Leave a comment

I learn a lot about a radio the first time I take it to the field. I’m not sure if it’s because being out of the shack helps me give it my full attention, or if it’s because field conditions vary and this allows me to see how flexible and adaptable the radio is.

On Monday (May 17, 2021), I was eager to hit the field with a new-to-me radio.

The previous week I didn’t log even one park or summit activation. Typically I’d hit at least two. There were a couple of reasons for this…

First, we had a fuel shortage in western NC and I didn’t want to burn any extra fuel for activations knowing we had some important family errands that week.

Secondly, I needed to hunker down and finish a number of projects I’d been working on including a lengthy two-part field radio kit feature for The Spectrum Monitor magazine, and a new in-depth TX-500 review for RadCom.  FYI: Part one of my feature for TSM will appear as the cover article in the June 2021 issue.

We also had a number of family projects to sort out. So a week at home perfectly timed with the fuel shortage.

The new radio

I collect reader and viewer suggestions and when I see that there’s a radio or product, in particular, folks would like to see tested, I try to obtain one.

One of the most requested radios lately has been the Xiegu X5105.

A number of readers have asked me to obtain an X5105 and take it to the field. Many are considering purchasing this (incredibly) affordable full-featured QRP transceiver, others own it, love it, and want to see how I like it compared with my other radios.

Last year, I came very close to purchasing the X5105 for review, but opted for the Xiegu G90 instead (here’s my review of the G90).

Even though the X5105 is only $550 US, I really didn’t want to make a purchase at this point because I’m budgeting for a new MacBook, new video camera, and I just purchased the TX-500.

So I reached out to Radioddity who is a sponsor over at the SWLing Post. I’d been in touch with Radioddity a lot as of late because I’ve been evaluating and testing the Xiegu GSOC for the past few months. They lent me the GSOC (and a G90 because I sold after my review) and I was in the process of packing up both units to send back to them.

I asked if they could lend me an X5105 for a few weeks. They were quite happy to do so and dispatched one in short order.

A clear relationship

Side story…

Back when I decided to place ads on the SWLing Post and QRPer.com, I worried about any inherent conflicts of interest. I read magazines that review products and can tell that they’re being gentle in their criticism because there’s a two page ad of the product immediately following the review. I don’t like that.

This conflict is something that’s almost inevitable with any radio publication that grows to the point of needing monetization to support it.

I made a few Golden Rules up front:

1.) I would only place radio-relevant ads on my sites. Period.

2.) My ads and sponsorships would be hand-picked and by invite only. I choose who can be a sponsor.

3.) I’m up-front with sponsors that my reviews call it like it is. If they send me product to review, I will give it an honest evaluation based on real-life use. If I don’t like it or can’t recommend one of their products, I’ll let my community know.

I’ve lost a couple of sponsors over Golden Rule #3 over the years. I’m okay with that because I’d rather not allow an advertiser on my site that can’t take customer criticism.

I invited Radioddity to be a sponsor of the SWLing Post last year after I had some positive interactions with them.

The Xiegu GSOC

Radioddity sent me the new GSOC to review in November 2020. I discovered in short order that the GSOC had some major issues and, frankly, I didn’t like it and certainly couldn’t recommend it. I communicated my concerns about this product with detailed notes and suggestions for improvement. I was open and honest about the GSOC on the SWLing Post (read the thread here).

Radioddity not only embraced my criticisms but sent them to the manufacturer and thanked me.

Impressive.

Blue Ridge Parkway (K-3378)

But back to the activation!

So on Monday, May 17, I had an errand in town that took me right past the Blue Ridge Parkway Folk Arts Center. The detour to do an activation was maybe two minutes, so there was no “fuel-shortage” guilt! 🙂

Also, I had a good hour to burn before I needed to go home and pack for a quick trip to visit my folks.

Equipment list:

I deployed the PackTenna 9:1 random wire antenna specifically because I wanted to see how easily the X5105’s internal ATU could match it.

I hopped on 40 meters first, hit the ATU button and it quickly found a 1:1 match–good sign!

This turned out to be a pretty easy and simple activation.

I started calling CQ and within 12 minutes I logged 11 stations.

I moved up to 20 meters knowing it would be a tougher band, but worked one more station–KG5OWB at K-0756–pretty quickly.

I was quite happy with  logging 12 stations in short order. A nice contrast to recent activations where conditions were so poor it’s been a struggle to get even 10 contacts within an hour.

I would have stayed on the air longer but (as I mention in the video) I wasted a good 20-25 minutes waiting on the landscape crew to finish mowing on/around the site before I set up my station. I didn’t want to be in their way.

Here’s my log sheet from the POTA website:

Video

Of course, I made one of my real-time, real-life videos of the entire activation. I’ve quite a long preamble in this one, so if you’re interested in skipping straight to the on-the-air time, go to 16:24.

X5105 initial thoughts?

So far, I like the X5105. It certainly accomplishes its goal of being an all-in-one “shack in a box.”

I performed this activation only using the X5105 internal battery. In addition, the ATU worked perfectly with the random wire antenna.

I like the size–it’s much smaller than I imagined. It’s also fairly lightweight.

It feels rugged, too–I wouldn’t be concerned about it getting easily damaged in the field.

The speaker works pretty well, but if the volume level is pushed too hard, it starts to splatter. I wish it could handle a little more volume before the splattering kicks in.

The ergonomics are pretty good. It didn’t take long to sort out how to use most of the functions.

One area for improvement? The owner’s manual. It’s poorly written and (frankly) reads as if it was rushed to print.

For example, I wanted to set up CW memory keying prior to hitting the field. Unfortunately, the owner’s manual was no help.

There’s actually a dedicated page regarding CW memory keying, but the first thing it does is reference a different section of the manual (without giving a page number). I followed the procedure, but it didn’t work. In fact, it didn’t make sense as it seemed lead me down the path of digital mode macros. I think the manual may be referencing a procedure before the last firmware update (which, it appears, changed the menu structure significantly).

If you can help guide me through setting up CW memory keying, please comment! I’m sure it’s a simple process, but I haven’t sorted it out yet.

Overall, though? I see why the X5105 is so popular. It appears to compete with a loaded Elecraft KX2. It’s a bit larger, heavier, and less “refined” but it’s also half the price of a loaded KX2.

I also think it’s a great radio for CW operators. The keying feels natural and responsive. It uses relays instead of pin diode switching, so QSK includes a little relay clicking. I don’t find it to be too loud, though.

I’ll be taking the X5105 out again very soon.  I’ve got it for 6 weeks, so it will get plenty of park and summit time. If you own the X5105, I’d love to hear your comments on this portable rig.

Thanks for reading!

Pairing the TX-500 and MPAS 2.0 on a beautiful morning activation of the Blue Ridge Parkway

2 Comments

On the morning of May 10, 2021, I had a hankering to head to the Blue Ridge Parkway for a quick park activation.

I had a particular spot in mind–one that’s only two miles or so from my QTH as the crow flies. The only wrinkle in my plan was that we were expecting rain all morning and at our house we were in thick fog and light, steady rain.

Normally when I have these conditions, I look for a sheltered site, but I thought it might be a great time to take out the TX-500 since it’s weather-resistant. Why not, right?

I packed the lab599 Discovery TX-500, my Chameleon MPAS 2.0 vertical, and my Elecraft T1 antenna tuner to pair the two. I also brought along some rain gear.

Although the activation site is close to home as the crow flies, it actually takes about 30 minutes to drive there. By the time I reached the site, the skies were mostly clear and the sun was shining! This time of year, it reminds me of living in the UK: if you don’t like the weather, just wait five minutes.

Gear:

On The Air

This was very much a road side activation. The spot I chose isn’t an overlook–although it did provide amazing views–it was simple a pull-off.

This is where antennas like the MPAS 2.0 are so useful: they are self-supporting and very quick to deploy. Since I was set up right off the road, I also appreciate using verticals rather than wire antennas since the antenna and throw line aren’t in the way of others who might choose to park in the same pull-off.  I can easily deploy the counterpoise and feedline so that it’s out of the way.

As with most park activations, I started on 40 meters CW and only operated 5 watts.

I quickly racked up five contacts on 40 meters, then the band fell silent.

I moved up to 30, then 20, down to 80, back to 60 and 40 again.

About 30 minutes had passed since I was last on 40 meters, so new hunters were checking the bands. I snagged a total of seven more contacts in about eleven minutes.

Obviously, 40 meters was the only band open that morning!

A quick note about 80 meters

I get a lot of questions from readers and YouTube subscribers about my use of the 80 meter band during the daytime.

I go into more detail about this in the video, but contrary to what many think, 80 meters can be a very useful daytime band for POTA activators.

While it’s true that you’re not going to work DX on 80 meters during the daylight hours (else, highly unlikely), you can still work local and regional stations.

Keep in mind that POTA, WWFF, and SOTA activations aren’t about working DX. DX is fun and perhaps a personal goal, but it has nothing to do with success in achieving a valid activation.

Basically, any contacts–DX or local–will get you what is needed for a valid activation.

If, like me, you live in a part of the country where there are a concentration of park and summit hunters/chasers within a daytime 80 meter footprint, then hop on that band and give it a go!

I’m not sure how useful this might be for activations in sparsely populated areas like Montana or the Dakotas, for example, but along the east and west coast, 80 meters is your friend.

At this particular activation, I didn’t didn’t employ an efficient antenna for 80 meters. While I’ve made numerous 80 meter contacts on the CHA MPAS 2.0 in the past, it’s just not physically large enough to be efficient on that band.  The CHA Emcomm III Portable or another long wire antenna would have provided better results. But I knew that 40 meters and possibly 30 meters would be my best bet that day, so the MPAS 2.0 was a great choice.

Again: don’t forget about 80 meters. It’s helped me snag many an activation!

Here’s my real-time, leal-life, no-edit video of the entire activation:

You might hear an audio pop when I’m keying on the TX-500. This is happening because I have the audio gain cranked up all the way for the video. While the speaker/mic can get quite loud, when I’ve got it located so far from the camera mic, I run it at 100% volume to be heard. I recently changed my CW T/R recovery time from 100ms to 400s which eliminated most of the audio popping.

Thank you for reading this field report! I hope you’re getting an opportunity to take your radios outdoors this week!
