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,

Thomas (K4SWL)

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.

G4USI has fun testing the matching ability of the Xiegu X5105 ATU

2 Comments

Many thanks to Stephen (G7VFY) who shares the following article posted on G4USI’s blog:

Xiegu ATU’s – just how good are they?

Preamble: Based on some social media comments, let me say at the outset that: a) I know that the ATU does not tune the antenna, but provides a good match to it; b) resonant antennas are more efficient; c) that you can tune a dummy load; d) just because you can tune something doesn’t make it an effective radiator. I do know these things. This post is intended as a bit of fun and to see just how much of a mis-match this ATU can handle to press objects into service as an antenna, even a very inefficient one. Please don’t take it too seriously!

Ask any Xiegu owner of the X5105, G90 or the XPA125B linear amp, and they will all tell you that they have great auto-tuners. Well, I own a X5105 and recently was lent a G90 for review for Practical Wireless. I decided to put the ATUs to the test using my X5105.

But what challenge to give it? Well, how about trying very, very long and very, very short antennas? What about metal gates, a cow shed roof, the framework of a polytunnel and a stock trailer?

Read on to find out how it really performs.

Click here to continue reading…

I love G4USI’s philosophy with this fun experiment: see if it’ll match, then see if you can get spotted!

Xiegu ATUs certainly have a wide matching range–so do the Elecraft KX series ATUs. Indeed, having a super capable trans match means that you don’t necessarily need an extra inline transformer to make matching a non-resonant wire easier.

And I see why G4USI mentions that there’s a difference between a good SWR and efficiency. It’s an important note because, yes, dummy loads will yield perfect SWRs!

Many, many moons ago, I used to participate in a fun contest where the idea was to make as many contacts as possible from not-so-standard antennas. The rules of the contest really pushed the operator to metal objects that, in no way, resembled an antenna. They didn’t allow electric fences or even gutters, if I recall correctly.

One year, I remember loading two identical small trampolines and my in-law’s house. I think I ran them QRP with my Elecraft K2 and used a ZM-2 manual tuner to match them. I’m sure they weren’t efficient, but it worked! I made several contacts with other contest stations and it was amazing fun!

Have you ever had success with a non-traditional antenna? Please comment!

A Xiegu X5105 Field Test by KN3A

10 Comments

I told Thomas I would do my own field test of the Xiegu X5105 doing a couple of Parks on the Air activations and what I thought of the radio.

I have had several radios I’ve used on POTA and SOTA activations over the past year and without a doubt my favorite radio for out in the field is my ICOM IC-705. It has everything I want in a portable radio, however I’m also enjoying it alongside my ICOM IC-7300 in the shack. Therefore I’ve looked at other portable radios for field use.

My latest acquisition was a used Xiegu X5105 that I purchased used on QRZ. The radio works fine and for the most part the menu system with it is very easy to understand. As Thomas has pointed out, the CW memory is absolutely insane to use. It just makes no sense to me why with the 10 memory slots that it’s really impractical to use more than the memory in Slot 1, which for me is the CQ POTA.  I would never even have known how to set it up in the first place without instructions to Tom that was shared in Tom’s post regarding the X5105.

I got the radio on June 3, played around with it in the shack to get familiar with it and programmed in the memories. I went to K-5481 (Wm. Penn State Forest), which has several parts scattered around eastern Pennsylvania. It has a very small 10 acre tract in the Cornwall mountains between Lancaster and Lebanon County, which is also at a SOTA summit. I used my Sotabeams EMCOMM III antenna and turned on the radio to start calling CQ POTA. For the life of me I could not get the CQ message to send, so I gave up on that and used my CW Morse paddle and did it the old fashioned way. I also spotted myself on the cluster and made 3 QSO’s on 40 meters fairly quickly. I had success on 30 and 17 meters as well. In total, there were 10 QSO’s made in about 45 minutes.

Other than my disappointment not being able to easily send the CQ from memory, overall I was pleased with the activation. When I got home I investigated again how to send CW. I also learned how to use the DSP to make it more narrow on CW, which I was thankful for. I then started to see if I could go hands free using my Heil headset that I was able to use when I had the G90. Unfortunately that did not work at all using the AD-1-iCM adapter as it would not transmit with the foot pedal. I did use the Heil headset in the side jack and put the radio in headset mode. I was disappointed to find that I had to increase the volume up the whole way to be able to hear CW loud enough for my old ears. When I unplugged the headset suddenly the radio RX was very loud. (If anyone can offer a solution, please let me know).

Today I took it to my local POTA park near my house, K-1418 (Samuel Lewis State Park). I used the same Sotabeams antenna and was on the air in no time. Band conditions were not so good and I ended up with 18 QSO in just over an hour. It was nice having the CQ function working, however I am used to the interval where it would automatically send every 7 seconds like the IC 705 does. Not a big deal, I just had to press the PTT button on the top.

I never tried using the radio on SSB before so I called unsuccessfully on 20 meters and went to 40 where KM4JEG called me and gave me a 55. Sadly, I had to take my headset off because when I keyed the mic I was hearing my distorted voice through the headset. So, headset was removed. I didn’t expect that was going to happen, so now on SSB, I’m not able to use the headset, at least on TX.

The Good:

I really like the internal battery in the radio. I did not have to bring the Bioenno 12v 3aH battery along. The internal battery works great!

It is very portable. I watched a YouTube video, and unfortunately I cannot find who it was, but they had an Osprey UltraLight Roll Organizer which I purchased on Amazon. This is perfect for storing the X5105 and the few accessories it needs, in my car so I’m always going to have a portable radio available when I travel.

The ATU is great on the radio. I can tune all the bands I want to work with the Sotabeams antenna. This also saves having an extra wire and external ATU like I would have to use on the IC 705 with this type of antenna.

The radio is nice and portable and will store nice in my car when not in use and will be ready to go.

The Bad:

The CW presets are almost worthless and not easy to get to. Once I found how to send from the memories, it only really makes sense to use one of the memory slots. I wouldn’t easily be able to switch to a 73 menu shortcut, then go back to the CQ memory.

With the headset plugged in, when I was transmitting CW, I could hear some distortion while it was sending, however it was not too bad, but something I’m not used to hearing.

The Ugly:

The headset for SSB could not be used at all due to the distorted noise it made. Also, the volume for the headset and the volume through the radio are night and day. As I mentioned before, when I unhooked the headset and the audio came out of the radio again, I had to quickly adjust the volume down.

My Opinion:

Overall, my opinion of the radio is this: For the price and the features it has, I would say it’s a good field radio, as it is easy to store in the car, it has the built in ATU if being used on a random wire antenna, and for 5 watts, people had no problems hearing me, even with poor band conditions and QSB. I hope this radio grows on me, and in the back of my mind don’t find myself thinking during the activation, gee I miss my IC-705 out here.

I know comparing the X5105 to the IC-705 is like comparing apples to oranges. Each radio has it’s good and bad. For the price difference, the Xiegu definitely is worth the price. I would never use it as a first HF radio in the hamshack if I were a new ham. This radio is also not going to be used by me on digital modes. If I want to do digital or work a contest while doing a POTA, then there is no doubt the 705 is coming along for the activation. The Xiegu will be used by me when I want to use a random wire antenna since it has the built in ATU, along with the fact it will be light in the backpack if I am hiking to a summit, and the IC 705 will be used with one of my end-fed half wave antennas or the Hustler vertical array so I don’t need the mAT-705 which I’ll use in the hamshack. I’m trying my best to get away from wires all over the place when I  activate, so the laptop computer is staying home. I really like the HAMRS logging program, which I highly recommend, on my Android Samsung S-20.

If anyone who reads this who has some insight into some of the issues I mention, please reply so I have a better understanding of this radio.

73!

A 3D Printed Battery Pack for the Discovery TX-500

1 Comment

Many thanks to Thomas (KC5KCT) who shares a link to this video demoing a 3D-printed Li-Ion TX-500 battery pack from Brewer 3D Design:

What a great design! I’d certainly give this a go. When he makes the project and finished products available, I’ll post links here on QRPer.com!

SOTA: Activating Bearwallow Mountain with the KX2, MPAS Lite, and Hazel

6 Comments
The MPAS Lite vertical has an impressive view!

I’ve been receiving a lot of comments lately from readers and viewers asking to see more Hazel in my reports and videos.

Hazel, if you’re not familiar, is my brown, white, and freckled canine shadow.

Hazel requires absolutely no prep time to go on a hike and summit/park activation. She’ll go from a deep, dreamy sleep where she’s chasing squirrels and her paws are twitching, to wide awake, tail wagging and nose pointed at the door in 2 seconds flat.

All it takes is the sound of me putting on my hiking boots (which must be louder that I imagined).

On Monday (May, 24, 2021) the weather was beautiful and I decided to finally add Bearwallow Mountain to my list of SOTA activations. Hazel was ready for a short hike!

Bearwallow Mountain (W4C/CM-068)

Bearwallow is one of the most popular summits to activate in the Asheville/Hendersonville area of western North Carolina. Any semi-seasoned local SOTA activator probably has Bearwallow in the logs. Why?

The Bearwallow antenna farm is extensive!

For one thing, Bearwallow is a ham-friendly site. A number of local repeaters are on this mountain and some of our local clubs have access to the summit. Once–I can’t remember the year–I even spent time with a club (I believe it was the Roadshow ARC) on Bearwallow for the ARRL Field Day. It was a blast!

Bearwallow is also a very accessible summit.

The trailhead to the summit (Google Map) is tucked away in the Upper Hickory Nut Gorge area–and there’s ample paved parking unless you happen to pick a very busy day (basically, any weekend with good weather will be busy!). Hazel and I were hiking on a Monday morning, thus there was very little activity and loads of parking spaces.

Some years ago, Conserving Carolina acquired the summit and much of the land on Bearwallow Mountain. Their conservation easement protects this area from future development and opens it for the public to enjoy.

Conserving Carolina maintains the trail system to the summit and all of the hiker information and blazing.They do a brilliant job!

There are two options for hiking to the summit: a proper foot trail, or you can take the Fire Tower Road which is the best choice for hikers who need a more gentle incline and flat gravel hiking surface.

Click here for a map of the trails (PDF).

Hazel and I decided to go up the foot trail and descend via the Fire Tower Road to make a loop.

We spotted a number of plants in bloom on the way up.

The foot trail is an easy one to hike, too. It’s well-maintained, as I mentioned, and there are only a couple of steep-ish sections.

There are even opportunities to take in views on the trail.

When you reach the top of the trail, it opens onto a pasture.

And the views are panoramic!

There are cattle all over the summit, so give them wide berth.

Speaking of cattle, Hazel is quite fond of them…or at least what they leave behind.

She’s been known to roll in cow patties when she has the opportunity (or if I’m distracted with something else…like performing an activation!).

Hazel and I found a nice spot to set up the station well within the activation zone. On summits like Bearwallow where there are clusters of communications towers, I prefer not to set up next to them. This is where that 25 meter SOTA activation zone (AZ) comes in handy.

Gear:

I had actually planned to use my Elecraft KX3 on this activation, but after setting it up, I realized quickly that my power cord had developed a fault.

Fortunately, I packed a spare radio.

Knowing in advance that this would be a short hike–before leaving the QTH–I also packed the KX2 kit in my backpack as a backup. I don’t always have the luxury of packing a second radio, but wow! Am I glad I did that Monday!

Setting up the Chameleon CHA MPAS Lite vertical, of course, was super easy.

On the Air

I started the activation on 20 meters and spotted myself to the SOTA network via the SOTA Goat app. Of course, before leaving home, I had also set up an alert on SOTAwatch so that the spots page would auto-spot me via the Reverse Beacon Network (RBN) if I didn’t have mobile phone coverage.

In short? The contacts started rolling in. I was very surprised to have this sort of response on a Monday morning.

In 22 minutes, I worked a total of 19 stations including one summit to summit (S2S)–thanks for that, Eric (VA2EO)!

I was very pleased with the number of contacts logged in such short order because I only had a max of 25-30 minutes to be on the air before I needed to pack up and head back to the QTH.

Here’s the full log:

Activations like this one remind me of what one can do with QRP power and a modest antenna.

Sure, at one point–after I had worked at least my first four to achieve a valid QRP SOTA activation–I increased the power from 5 watts to a cloud-scorching 10 watts! 🙂

Here’s a QSO map of the contacts:

Video

Here’s my real-time, real-life (a.k.a. it’ll put you to sleep) video of the entire activation:

I must apologize for the audio in this one–it’s a little weak due to how the camera was set up.

Hazel at it again

So I brought along a retractable leash/lead for Hazel for this particular outing.

This leash allows her to roam more freely during our actual hike. On the summit, I locked the leash and attached it to my pack so it would keep her within 4 feet or so of where I was sitting which was cow patty-free.

At one point, near the end of the activation, when I was trying to manage a few calls, off-camera Hazel discovered that the leash unlocked, allowing her more flexibility to roam.

I looked up to discover that she found a semi-moist cow patty I somehow missed and was preparing to “enjoy” it. While sending CW and trying to keep from knocking down the camera, I used my left foot to put the brakes on her leash. She knew I was struggling, though, and tugged more.

I managed to stop her before even one paw plopped in the patty. Somehow. It was a very close call, though.

If you’ve watched my activation videos before, you’ve no doubt gathered that I’m not a multitasker. This little event really tested my ability to hold it all together on and off camera! 🙂

After packing up the station, Hazel and I took the Fire Tower Road back to the car. It was a very pleasant stroll and cow patty free.

Thank you for coming along with me on this SOTA activation and making it to the end of the report. You deserve an award! Please treat yourself to a local summit or park soon!

Thank you & 73,

Thomas (K4SWL)

The new Xiegu X6100 portable HF transceiver: Yes, it’s real and no it’s not vaporware

49 Comments

It seems folks are now finding out about the new Xiegu X6100 HF & 6 meter portable transceiver.

There have been a few rumors about it, so I thought I’d share some of the few details that have been confirmed.

What is the X6100?

If the Xiegu X5105 and Xiegu GSOC had a baby, it would look like the X6100.

The X6100 is a completely self-contained SDR QRP transceiver much like the X5105. The X6100 sports a 4″ high-resolution color capacitive touch screen and is built on on a quad-core processor, 4G ROM, and 512MB RAM. I assume this will run on a similar Linux version/distro as the GSOC.

The X6100 will include an internal automatic antenna tuner (ATU) and a 3500 mAh internal rechargeable Lithium Ion battery pack.

Power output will be 5 watts when using the internal battery pack and 10 watts when connected to an external power source.

Key features:

  • Modes: USB/LSB (J3E), CW (A1A), FM (F3E), RTTY (F1B), AM (A3E)
  • Receiving: 0.5MHz~30MHz, 50MHz~54MHz
  • Transmitting: 1.8~2.0MHz, 3.5~3.9MHz
    5.3515~5.3665MHz 7.0~7.2MHz 10.1~10.15MHz 14.0~14.35MHz 18.068~18.168MHz 21.0~21.45MHz 24.89~24.99MHz 28.0~29.7MHz 50~54MHz
  • External voltage range : 9.0~15.0VDC
  • Integrated SWR meter
  • Voice and CW memory keying
  • Integrated modem
  • Native Bluetooth and WiFi functionality (easy keyboard and mouse connectivity)
  • Two USB interfaces supporting HOST and DEVICE
  • Standard high stability TCXO
  • 24bit sampling rate and “large dynamic RF front-end unit”
  • Ruggedized chassis and backlit buttons
  • Maximum current consumption in receive: 550mA

Early Product Sheet

I’ve also been sent a pre-production product brochure. This has a number of details and, as you’ll see, it even hasn’t been through a final edit.

Click here to download the preliminary Xiegu X6100 product brochure (PDF).

Pricing and availability

Pricing and availability have not been determined at time of posting. I will post an update when that information can be confirmed.

I can only assume bringing this new radio to fruition will take time. Most radio manufacturers are struggling to keep up inventory levels as we work our way out of the C-19 pandemic supply chain issues. Parts availability has become a real issue.

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.
