POTA Field Report: Three park run with two transceivers & two antennas

Yesterday, I started the day hoping I might fit in one afternoon activation at a local park. In the morning, however, my schedule opened up and I found I actually had a window of about six hours to play radio!

Instead of hitting a local park, I considered driving to parks I’d been planning to activate for months.

I may have mentioned before that, earlier this year, I created a spreadsheet where I listed of all of the parks I planned to activate in 2020.

From earlier this year–many of the parks listed as “rare” are much less so now!

Each park entry had the park name, POTA designator, priority (high/medium/low), difficulty level for access, and a link to the geo coordinates of where I could park and possibly hike to the site. I spent hours putting that list together as finding park access–especially for game lands–isn’t always easy.

Yesterday morning, I looked at that sheet and decided to knock two, or possibly three off the list.

I had already plotted the park run, driving to Perkins State Game Land (K-6935) near Mocksville, then to the NC Transportation Museum State Historic Site (K-6847) in Spencer, and finally Second Creek Game Land (K-6950) in Mt Ulla.

The circuit required about three hours of driving. Here’s the map:
When I plan an activation run, I factor in the travel time, add ten minutes extra if it’s my first time at the site (assuming I’ll need to find a spot to operate) and then assume at least one hour to deploy my gear, work at least ten stations, and pack up.

Using this formula, I’d need to allow three hours for driving, plus an additional three hours of operating time, plus a few minutes to sort out an operating spot at Perkins Game Land. That would total six hours and some change.

Knowing things don’t always go to plan, I decided I’d quickly omit the NC Transportation museum if I was running behind after the Perkins activation. In fact, I felt like the NC Transportation Museum  might be out of reach, so I didn’t even schedule the activation on the POTA site.

Perkins State Game Land (K-6935)

I arrived at K-6935 a little before noon (EST).

Since this is the week after Christmas, I had a hunch game lands could be quite busy with folks trying out their new hunting gear and I was correct.  I passed by the first small parking area and it was packed with vehicles, so I drove on to the second parking area I identified via Google Maps satellite view.

The second parking area was also busy, but was larger. There was just enough room for my car to park between two trucks.

Gear:

I donned my blaze orange vest–a necessity at any game land–and walked outside to asses the site. In short? It was a tough one. There were no easy trees to use for antenna support and I simply didn’t have the space. I knew folks would walk through the area where I set up my antenna so a wire antenna would have acted a lot like a spider’s web.

I pulled out my trust Chameleon MPAS Lite vertical antenna and deployed it next to the car. I rolled out the counterpoise into the woods paralleling a footpath so no one would trip on it.

Since I had no room to set up outside, I operated from the backseat of my car–it was actually very comfortable.

I pulled out the Elecraft KX3 and hooked it directly to the MPAS Lite–it easily tuned the antenna on both 40 meters, where I started, then later 20 meters.

I very quickly logged 13 stations on 40 and 20 meters.

While on the air, a number of other hunters discovered the parking area was nearly full–some turned around and left. I decided to cut the activation with 13 logged and skipped doing any SSB work. I accomplished what I set out to do here, was short on time, and I wasn’t actually using the game land for its intended purpose. Better to give others the parking space!

I quickly packed up and started the 30 minute drive to my next site.

NC Transportation Museum State Historic Site (K-6847)

The Cameleon MPAS Lite

I knew what to expect at the NC Transportation Museum because I’ve visited the museum in the past and, earlier this year, scoped out a spot to activate the park in their overflow parking area.

The museum is closed on Mondays. In general, I avoid activating parks and sites that are closed. I never want to give anyone at the park a bad impression of POTA activators.

In this case, however, the overflow parking area is wide open even when the park is closed and there was no one at the site. I felt very comfortable setting up the CHA MPAS Lite which is a pretty stealthy antenna. Indeed, as I was setting up, I’m guessing it was a museum employee that passed by in their car and waved–no doubt, POTA activators are a familiar site!

Gear:

I set up my portable table behind the car under the hatchback so I took up the least amount of space.

I used the table primarily so I could shoot one of my real-time, real-life videos of a park activation. Readers have been asking for more of these and I’m happy to make them if they’re helpful to even one new ham.

In the end, I logged 13 stations and didn’t try to work more because I was still on track to activate one more park. I didn’t feel bad about only working 13 stations, because this site has been activated many times in the past–in other words, it wasn’t exactly rare.

Here’s my video of the activation:

Second Creek Game Land (K-6950)

The Cameleon MPAS 2.0

I arrived at K-6950, the final park, around 14:50 EST (19:50 UTC).

Only one vehicle car was in the parking area, so it was easy to pick out a spot to set up.

Gear:

Again, since I planned to make a video of the activation, I set up my portable table.

I decided en route to the site, that I’d use the Chameleon MPAS 2.0 vertical at Second Creek. Although I’ve used the more compact Chameleon MPAS Lite at a number of parks–including the two previous parks–I had a great spot to deploy the taller MPAS 2.0.

As with the MPAS Lite, deployment was very quick. the MPAS 2.0 vertical is made up of folding pole sections–much like tent poles. As with all Chameleon gear I’ve ever used, the quality is military grade. Full stop.

I started calling CQ on the 20 meter band in CW this time. Within a minute or so I logged my first contact, followed by five more.

I then moved to the 40 meter band and logged twelve more stations in twelve minutes.

I decided to then give SSB a go as well and logged two more stations for a total of twenty stations logged.

Here’s a video of the activation:

I would like to have stayed longer at Second Creek and even used the MPAS 2.0 on 80 meters, but frankly I was pushing my time limit to the edge.

All in all, it was a brilliant three park run!

These days, it’s difficult to pack more than three parks in my available time–in fact, I think this was the first three park run I’d done in months. During National Parks On The Air (NPOTA) in 2016, I’d been known to pack four or five parks in a day–it was so much fun.

Here’s my QSOmap for the day (click to enlarge):

Getting outside on such a beautiful day, driving through some picturesque rural parts of my home state, and playing radio? Yeah, that’s always going to be a formula for some amazing fun!

Icom publishes AH-705 antenna tuner details

Many thanks to Rob Sherwood (NC0B) who notes that Icom has published details regarding their new AH-705 antenna tuner which is designed to pair directly with the Icom IC-705 QRP transceiver.

Many Icom IC-705 owners have been waiting to learn more about the AH-705 before purchasing a dedicated portable ATU for their IC-705. Some of these details may help potential customers make a purchase decision.

Key specifications and features per Icom:

 

  • Covers the 1.8 MHz to 50 MHz bands

30 m, 98.4 ft or longer antenna: 1.8 – 54 MHz, 7 m, 23 ft or longer antenna: 3.5 – 54 MHz
* Depending on operating conditions or environments, the tuner may not be able to tune the antenna.

  • SO-239 antenna connector for 50 Ω antenna such as dipole or Yagi
  • “Terminal connector”, binding post socket adapter supplied for a long wire antenna

  • 2-way power sources using alkaline batteries (2 x AA cells) or external 13.8 V DC*
    * 13.8 V DC should be taken directly from an external power supply, not through the IC-705.
  • IP54 dust-protection and water resistance construction*
    * The connectors should be covered with an adhesive tape or a jack cover to prevent water seeping into the connection.
  • Full automatic tuning, just push the [TUNER] button on the IC-705
  • Latching relays used for saving power consumption
  • 190 × 105 × 40 mm; 7.5 × 4.1 × 1.6 in, 450 g; 15.8 oz* compact design
    * Battery cells are not included.
  • 45 tuner memories

Of course, I don’t have an AH-705 in hand to test yet, so there’s no way I can comment on performance.

Still, I can’t turn of the reviewer inside so I feel I can make some superficial comments assuming the specs don’t change.

Potential positives?

  • Complete integration with the IC-705
  • Could (potentially–?) be permanently mounted outdoors at the antenna feed point as a dedicated remote tuner
  • IP54 dust and water resistant
  • Power from internal batteries and an external DC source
  • It’s an Icom product, so I would expect excellent overall quality

Potential negatives?

  • Maximum wattage is only 10W, which I suppose is okay if you never put an amplifier between the IC-705 and the AH-705
  • Based on Icom specs, the AH-705 is larger than other portable ATUs at 7.5 × 4.1 × 1.6 inches. For example:
  • Some have noted pricing around $350 US price–that’s a premium for a portable ATU considering the Elecraft T1 is $180 assembled and many LDG models are less than $200. Of course, none of those ATUs have an IP54 rating, either.
  • Speculation here, but the AH-705 might only work with the IC-705 or Icom radios with similar ATU commands. One original pre-production prototype image of the AH-705 shows a power switch; the latest images do not. Like the mAT-705Plus, I’m not sure if the AH-705 can be turned on in order to tune only via RF sensing without essentially modifying a control cable to trick the ATU into powering up.

I was a little surprised to see that the AH-705 “only” has 45 tuner memories. In truth, I never really pay attention to this spec because I’m primarily a field operator. My radio sessions are only an hour or two long and I routinely pair my transceivers with a wide variety of antennas, so a portable ATU never has a chance to develop a complex tuner memory map for any given antenna. But as a reviewer, I try to step in other operators’ shoes so I see where this could be a slight negative for those who plan to use the AH-705 at home and connected to only one antenna. As a point of comparison, the mAT-705Plus has 16,000 tuner memories. Still, memories only help shave off a bit of the auto-tuning time. This would never have an impact on my purchase decision.

Biggest positive for me? IP54 rating

Since the AH-705 is designed to be dust and weather resistant,  it could be mounted at the antenna feed point. At home, perhaps it could act like an externally-mounted, remotely-controlled antenna tuner. I’m not sure what the maximum length of the control cable could be, but Icom Japan even lists a 16 foot control cable as an accessory. Of course, you would still need to follow Icom’s guidance about protecting the antenna, transmitter and control cable connection points.

Biggest negative for me? The size.

If the AH-705 specs are correct, it’s a little surprising Icom designed a portable ATU that’s this large. As you can see in the image above, it easily fits in the LC-192, but frankly since I’ve been an Elecraft T1 tuner user, I’ll notice that the AH-705 is 3.1″ longer, 1.6″ wider, and .7″ taller than the T1. It will certainly take up more backpack space.

Of course, unless I build an IC-705 control interface for the Elecraft T1, I can’t directly pair it with the IC-705 like I could with the AH-705. That said? I personally prefer pressing a tune button on the T1 and sending “QRL?” instead of hitting the PTT or CW key and allowing the IC-705 to kick in a continuous tune cycle for a few seconds. You might have noticed in some of my videos that when I tune to a new CW frequency, I’ll listen for activity, then tap the TUNE button on the T1 and send “QRL?” or “QRL de K4SWL”. By the time I’ve sent that string, the T1 has typically already found a match.

How will it perform?

I’ve got to assume the AH-705 will perform well. Icom tends to give their products thorough QC before shipping them to customers. I don’t anticipate any issues with the AH-705 as I did with the original maT-705, for example.

I’ll plan to test the AH-705 after it’s available.

POTA Field Report: Two quick activations with the IC-705, mAT-705Plus, and CHA MPAS Lite

Back in the days of the National Parks On The Air (NPOTA) program in 2016, I made it a habit of doing multiple park activations in a morning, afternoon, or evening. I’ve done less of this in Parks On The Air (POTA) this year only because my time is more limited. Still, I love doing multiples because it gives me an opportunity to set up, play radio, achieve a valid activation, pack up, move on and repeat. Makes me feel like the only member of a pit stop crew. I love it!

Some call this RaDAR (Rapid Deployment Amateur Radio).

Monday (December 21, 2020) I had a block of time in the early afternoon to fit in up to two activations, en route to the QTH if all went well. While it wasn’t three, four, or five activations in an afternoon, I knew it would be a challenge to fit both in my tight schedule. If an activation took much longer than 30-40 minutes, I wouldn’t be able to complete both.

Since my goal was a quick activation, I reached for the Chameleon MPAS Lite vertical antenna which is so easy to deploy. I paired it with the Icom IC-705 and new mAT-705Plus ATU.

Gear:

Johns River Game Land (K-6915)

My first stop was Johns River Game Land. During hunting season, I spend less time in game lands because parking areas are full and even though I wear a blaze orange vest, I’d rather not be shot if I venture into the forest to set up. 🙂

Johns River has a very accessible large parking area off of a highway near Morganton, NC and I’ve never seen more than two vehicles there at a time.

I arrived on site just before noon on Monday and set up at the edge of the parking area. Unfortunately, this parking area is less than bucolic. Those who use this game land access point leave trash everywhere. You can tell groups gather with pickup trucks, make fire pits, drink beer, break bottles and throw their trash in the woods. Being a firm believer in Leave No Trace, this really, really gripes me.

I found a spot with the least amount of trash and set up in the gravel portion of the parking area so I didn’t drive over sharp objects or step on broken glass.

This is where the Chameleon MPAS Lite came in handy: I plunged its spike in the ground, unrolled the counterpoise, extended the antenna, and I was on the air in perhaps three minutes. No need to walk into the weeds and trees to hang an antenna.

I made a real-time, no-edit video of the entire activation with my iPhone. Since the iPhone was in use, I didn’t take a single photo at Johns River. That’s okay, though, because–as I mentioned–there wasn’t a lot there in terms of scenery. 🙂

Here’s the full video:

All in all, I worked 11 stations in short order. The video above approaches 30 minutes, but much of that time is dialog before the activation started. Toward the end, I also have the Mat-Tuner mAT-705Plus tune from 160-6 meters with the CHA MPAS Lite. If you’d like to skip directly to that bit, here’s the link.

I quickly packed my gear and set my sites on the next activation.

Lake James State Park (K-2739)

I arrived at Lake James State Park around 19:00 UTC and was on the air ten minutes later with the same equipment I used at Johns River.

I love Lake James because there are so many picnic sites and all have tall trees (for wire antennas) and gorgeous views. It doesn’t get any better for a POTA activator. Also, it’s a very short walk to the picnic spots. Since I recently sprained my ankle and can’t hike at present, this is a major plus. Like Johns River, I also have mobile internet access at Lake James which was a huge plus since the POTA spotting page wasn’t pulling spots from the Reverse Beacon Network like it normally does.

The Chameleon MPAS Lite 17′ vertical (above) served me well once again.

I worked 11 stations in short order.

Even though a vertical antenna isn’t optimal in the foothills of western North Carolina (due to poor ground conductivity), it had no problem sending my 10 watts across the US into California and up to Alaska. I still get a major thrill out of MPW (mileage per watt) like this!

I also made a short video at Lake James where I primarily talk about the trade off between convenience and performance with regards to field antennas. I also work a few stations on 30 meters:

Here’s a QSOMap of all of my contact from both Johns River and Lake James on Monday December 21, 2020:

Happy Holidays!

Today is Christmas Eve and I’ve no plans to do an activation (torrential rain, if I’m being honest, is dissuading me).

Instead, I’ll spend quality time with my family here at home. Same for Christmas Day. This evening, we’ll watch some our favorite Christmas shows/episodes: The Good Life (a.k.a. Good Neighbors), The Grinch Who Stole Christmas, and of course a Charlie Brown Christmas to cap off the evening.

I know 2020 has put a damper on gatherings with family and friends–our family has certainly felt it this year. With that said, I think the amazing thing about ham radio is the community we build over the air–it’s certainly been an important community for me, this year especially.

Thank you, radio family!

Here’s wishing you, your family, and your friends the very best of the season!

73,
Thomas

POTA Field Report: Lake Norman State Park (K-2740) December 14, 2020

Monday afternoon (December 14, 2020), after completing a long to-do list of errands, I found myself with a chunk of free time in the late afternoon. Of course, I like to fill free time with radio time, so I packed the car and headed to one of my favorite spots: Lake Norman State Park (K-2740).

I love Lake Norman because it’s only a 35 minute drive from my parents’ house (where I was that Monday) and it’s nearly ideal for POTA because they’ve a number of picnic tables widely spaced, and lots of tall trees–a perfect spot for wire antennas. It’s also a quiet location and has good “POTA Mojo”–meaning, I’ve never had difficulty racking up contacts there.

Gear:

I was the only person at the picnic area of Lake Norman that afternoon. No surprise as it was after 3:00 PM local and temps were on a fast downward trend after a front moved through earlier in the day.

You may be able to see the Emcomm III hanging in the tree.

I used my arborist throw line and deployed the Emcomm III Portable antenna with ease.

On the Air

I hopped on the air around 21:30 UTC and started calling CQ POTA. The Reverse Beacon Network (RBN) spotted me and the POTA website auto-spotted me under a minute. Within ten minutes, I logged 8 contacts on 40M.

I then moved to 20 meters and worked an additional 5 contacts within 15 minutes.

Since I had worked a total of 13 stations, I had three more than needed for a valid POTA activation.

Since I was using the amazing Emcomm III Portable random wire antenna, I decided to move to 160M just to see if anyone work work me on the “top band.”

To be clear, 160 is one of the least active bands in POTA for obvious reasons: few ops care to deploy an antenna that can tune up on 160M, and few POTA hunters have an antenna at home to work the Top Band. Although it’s not as efficient as a resonant 160M antenna, the Elecraft T1 and mAT-705 easily tune it and get a great match.

I called CQ for a few minutes on 1810 kHz in CW and N4EX replied. Woo hoo! My first 160M POTA contact as an activator.

I then moved up to the phone QRP calling frequency of 1910 kHz and called CQ for about 10 minutes. No dice. Since I spotted myself, about two stations attempted to make contact, but unfortunately, my five watts just couldn’t be heard.

I checked the time at this point and it was 22:30 UTC. The sun was setting over Lake Norman, so I started packing up.

It was then received a text from my buddy Mike (K8RAT). The message read, “80M?”

I thought it might be fun to work Mike on 80M, so I re-connected the antenna and tuned up on 3538 kHz.

I think I called CQ once, and Mike replied with a strong signal. We had a nice exchange and when we sent our 73s, I heard a few stations calling me. Of course…the RBN picked up my CQ for Mike and the POTA site spotted me.

To be clear: it’s next to impossible for me to cut an activation short when I have hunters actively calling me, so I started replying.

Getting late…

Turns out, 80 meters was on fire. In 15 minutes, I logged 17 more stations–from Florida to Ontario–with 5 watts.

Next thing I know, it’s dark. Like, pitch dark…

My iPhone struggled to make this photo look brighter without the flash engaged.

Side note: someday, remind me to write a post about how one of my earliest National Parks On The Air (NPOTA) activations carried on until it was pitch dark outside and how that one activation forever changed how I pack my gear. In short: if you’re in the field and you aren’t intimately familiar with your gear and how its packed–even if you have a headlamp–there’s a good likelihood you’ll leave something behind.

It then hit me that Lake Norman State Park closes at sunset in the winter.  Doh!

Friendly park rangers

I finished my last exchange (with W3KC) and sent QRT despite a few others still calling me.

 

As I quickly powered down the IC-705, I noticed a truck pass by slowly on the road behind me. He drove to the end of the road then turned around and stopped behind me. I knew it was a park ranger doing final rounds.

He walked down to my table with flashlight in hand and I greeted him with an apology as I quickly packed up my gear. He was incredibly kind and encouraged me to take my time. He also saved me a trip to the car to grab my headlamp by illuminating the area with his Maglite flashlight/torch.

The park ranger asked a number of questions about ham radio, POTA, and the equipment I was using as I packed up. He told me he’s always found it fascinating and had met other radio amateurs at the park doing activations. I gave him my contact info and I hope he considers checking out the world of radio.

Because I’m meticulous about how I pack (again, lessons learned from the past) I had no issues in low light and left nothing behind.

I drove out of the park at exactly 6:00PM which is the park’s closing time. I was happy, at least, that I hadn’t delayed their closing!

All-in-all, it was a very fun activation–so much fun, I lost track of time. I logged 30 stations all over North America on four bands with 5 watts.

Have you ever found yourself operating and packing up in the dark? Any stories to share or advice? Please comment!

A simple 3D-printed foot for the Icom IC-705

A number of readers have asked about the small foot under my IC-705 in recent POTA field reports.

One of my biggest criticisms of the IC-705 is that it has no built-in foot to tilt the radio for an optimal operating position. On the other hand, it does have a number of attachment points on the bottom including a standard tripod mounting point and several 4mm points.

Shortly after I received my IC-705, I checked Thingiverse knowing a clever ham would have designed some sort of leg or tilt stand.

One of the first designs I found was the most simple: this foot by “Viktor39” that attaches to the bottom of the IC-705.

It prints quickly and uses very little material (no support structure). Mine is made of orange PLA (because that’s what my daughters had been using), but I’m sure ABS would be a better choice.

You’ll need two 4mm x 10 screws to attach the foot to the bottom of the IC-705.

I’ve found that the foot is small enough that I never need to detach it even in transport.

Curt builds an Icom IC-705 control interface for his Elecraft T1 ATU

Many thanks to Curt (WU3U) who recently contacted me and mentioned he had built an IC-705 control interface for his Elecraft T1 ATU. This is a homebrew project based on others’ work and uses the FT-817 control port on the side of the T1 tuner.

I asked Curt if he could share a little more about his tuner to post here on QRPer:

Hi Thomas, I can’t take credit for the interface, as a guy in Japan designed it. When I built mine the entire instructions and notes for code for the PIC controller were in Japanese. I used Google translate to translate all of the information and I was able to successfully program the PIC chip and build the circuit. He has since released the details and code in English.

There are two designs: one with an on/off switch, and a newer version without an on/off switch that has auto power save. Both circuits are the same but the software for the PIC chip is different. If you build the one without the on/off switch there is a very specific sequence of connecting and disconnecting the device and it’s my opinion that the one with the on/off switch is the version that makes more sense to build. It shouldn’t matter which order you connect everything up and you simply throw the on/off switch to turn the device on and off.

Building the interface takes an understanding of a fairly simple electronic schematic and acquiring the parts. You also have to have a PIC programmer and the software to write his .hex file into the PIC controller chip.

The parts for the interface are all very common parts. The resistors are standard values. My build cost me about $30 in parts but I had to buy many of them in bulk from Amazon like the enclosures, switches and 3.5mm jacks and circuit boards to name a few. Individually the parts were $30 but my bulk order cost me much more. I also had to buy a PIC programmer for $25 and figure out what software I needed to download to program the PIC chip with the author’s code. It takes an experienced builder about two hours to build the device but it’s not out of the realm of a semi-novice as long as they can get the PIC chip programmed.

Here is the original code using the on/off switch. Everything is now in English:
https://amateur-radio.cocolog-nifty.com/blog/2020/11/post-1eb3cf.html

Here is his newer version with the same circuit design eliminating the on/off switch by using a different PIC program allowing the interface to have auto power shutdown (low power standby) but there is a specific order for connecting and disconnecting the interface. With this version there is still drain on the battery but the designer thinks that drain is less than the normal self discharge of the battery. I feel that any discharge combined with the self discharge of the battery will be more discharge than using the design with the on/off switch.

I think this is a brilliant project and certainly one worth considering for those of us who already own an Elecraft T1 ATU and would like full control from the IC-705.

Thank you for sharing these details, Curt!

 

Steve’s new Icom IC-705 SOTA lap desk

I’ve been in touch with Steve (WG0AT) recently. He happened to be selling his FT-817 at the same time I was looking for a narrow CW filter.  The stars aligned and I now have a 500 Hz Collins CW filter in my FT-817ND.  Thanks, Steve!

Steve also took delivery of his Icom IC-705 recently so we’ve been trading notes about this fine rig. He and I both have a fear of the ‘705 falling off our laps when using it in the field for SOTA and POTA activations.

Steve, being the king of ham radio customization, started working on a portable desk. He shared iterations along the way and his final product seen in the photo above.

The desk is a brilliant design: it’s lightweight, sturdy, has holes for managing wires/cables, a strap to hold it your leg, and even a cup holder. The cup holder is a bit of genius because he likes a good cuppa tea in the field just like I like a good cuppa joe.

The IC-705 will be able to bolt directly to the lap desk so there’ll be no fear of it falling off a cliff in the field.

Of course, the desk will work with any field-portable radio. Steve shared a few more photos:

I’m going to attempt to build a similar desk for my IC-705. The great thing about it is it’ll easily fit in a backpack, too.

Thanks again for letting me share your photos, Steve! We look forward to seeing this desk in action at a summit near you!

POTA Field Report: One antenna and two transceivers at South Mountains State Park (K-2753)

On Tuesday (Nov 17, 2020), I decided to activate South Mountains State Park (K-2753) for the Parks On The Air (POTA) program. As with my activation at Lake James the day before, it was impromptu. Basically, the weather was beautiful, so I couldn’t resist.

In fact, the weather was so nice, on my way to South Mountains I passed by Bakers Mountain County Park and hiked their full trail including the summit. While on that hike, I ran into Kenneth (W4KAC) who had just activated Bakers Mountain for Summits On The Air (SOTA). This was a bit of serendipity because I, too, plan to activate Baker’s Mountain for SOTA and Kenneth provided some great details for finding the summit (which is not actually on the park grounds).  It was great running into a fellow QRPer and talking shop, too!  I hope to meet Kenneth again in the field.

I arrived at South Mountains State Park mid-afternoon and set up near one of their large covered picnic shelters.

Although I’ve activated South Mountains State Game Land numerous times in the past, I’ve never activated the actual park. The last time I popped by the park, there was already another ham there in the middle of an activation, so I moved to the adjoining game land that day.

South Mountains State Park is a very popular park–indeed, it’s currently the second most activated park in North Carolina.  Although I didn’t realize it at the time because I had no internet access, there was actually another operator somewhere at the park on the air at the same time I was.

On the Air

Once again, I set up the Chameleon CHA MPAS Lite vertical antenna for this quick activation.

Besides being such a quick and easy antenna to deploy, I love how stealthy it is, essentially disappearing against a background of trees.

As you might imagine, activating a park while someone else is also activating it is not ideal. At the time, I couldn’t figure out why contacts were coming in so slowly, but no doubt many hunters probably thought they’d already worked me because they worked the other activator.

In the end, though, my biggest problem at South Mountains was the fact my battery died in the Elecraft T1 ATU after finding a match on the 20 meter band. A 9 volt battery should last months in the T1, but the battery I put in it several weeks ago had already been used in another device for a few months. I had meant to replace it with a fresh cell. I actually packed a new 9V battery in my main radio pack, but I didn’t have it with me on this trip because both South Mountains and Lake James were unplanned activations.

I spent a good half an hour on the 20 and 30 meter bands where I had a decent match, but only logged three or four hunters. Conditions were not ideal on the higher bands.

I really needed to move down to the 40 meter band knowing it would be more productive, but I had no way to find a match for the IC-705. (Lesson learned: I’ll never again leave home without my Emtech ZM-2 as a backup!).

Fortunately, I remembered I had the Elecraft KX1 field kit. The KX1 now permanently lives in my car so I know I always have a complete radio kit for impromptu field activations.

The KX1 has a built in ATU, but it’s not as robust and versatile as the T1 or the internal ATUs in the KX2 or KX3.

I tried loading 40 meters and got a 2.5:1 match. I’m sure the KX1 would have plugged along, but I don’t like pushing much over 2:1 when I don’t have to.

After tinkering with the CHA MPAS Lite counterpoise for ten minutes, I finally found a length that, if half suspended, allowed the KX1’s internal tuner to achieve a 1.9:1 match. Good enough!

I started calling CQ on 40 meters and within a few minutes, I logged a total of 12 contacts.

The KX1 saved my bacon that Tuesday!

All in all, I really enjoyed the time at South Mountains State Park. It was beautiful weather and I had an idea spot to set up and operate. I’ll certainly come back here in the future.

I’ve also decided that I’m going to start packing a resonant antenna option in the car with my KX1 field kit. It’s only this year that I started using multi-band and random wire antennas that require an ATU; they are mighty convenient indeed, but it’s always nice to have a resonant option on hand as well.

POTA Field Report: Lake James State Park (K-2739) with the Icom IC-705 and CHA MPAS Lite

Monday (November 16, 2020), I made a detour to the Catawba River access of  Lake James State Park (K-2739) to try a late morning POTA activation.

I didn’t plot this activation in advance, so had to work with what I had in the trunk/boot of the car.

I did a quick inventory and found my Chameleon CHA MPAS Lite vertical antenna packed and ready to deploy. (I always have an antenna tucked away in the car because…well, because!)

In terms of radios, I had the Icom IC-705 and Elecraft T1 antenna tuner packed as well. Woo hoo! A perfect combo! Let’s go!

Gear:

It was blustery and cold Monday morning due to a front that moved through during the night, so it was no surprise that the picnic area was completely void of (sane) people.

I found a picnic table on the bank that was relatively sheltered from some of the stronger gusts moving across the river. It was still quite windy, though, so I propped the MPAS Lite field pack on the table to provide a bit of a wind break for my log book.

Setup was quick. I don’t think I needed more than 4-5 minutes to have the CHA MPAS Lite deployed. This is one of the advantages of field portable verticals. The disadvantage? Verticals aren’t the most effective antennas in this part of North Carolina where ground conductivity is so poor. Still…I knew I could at least grab my ten needed contacts to have a valid POTA activation.

On the air

I won’t lie: it was slow-going.

For one thing, it was 11:00 local on a Monday morning–not exactly a prime time for a park activation.

I first tried making some SSB contacts on 40 meters and spotted myself on the POTA network. I managed to log 5 hunters in 30 minutes. With patience and time, no doubt, I could log ten SSB contacts, but I didn’t have time to wait, so I moved over to CW.

Oddly, the higher HF bands were in better shape than 40 meters that morning. One of my first contacts was NL7V in Alaska on 20 meters. A most impressive contact with 10 watts into a vertical.

I was on the air a full hour and did manage to log a total of 10 contacts. I’m certain if I would have deployed a wire antenna I would have had even better luck. Indeed, had I thought about it in advance, I could have actually deployed the MPAS Lite as a random wire antenna. (Doh!) That’s one of the great things about this antenna system is that it can be configured so many different ways.  Next time…

Still…I thoroughly enjoyed my time at Lake James State Park. I’ll make this detour again in the near future.

The Icom IC-705 continues to prove its worth as a superb little POTA transceiver!
