Testing my MTR-3B field kit before a weekend of SOTA (spoiler: that never happened)

6 Comments

Two days before Hurricane Helene impacted western North Carolina (Wednesday, September 25, 2024), I stopped by the Blue Ridge Parkway for a quick POTA activation to thoroughly test my MTR-3B self-contained field kit.

This was crucial, as I had plans to conduct multiple SOTA activations during the 2024 W4 SOTA campout in north Georgia the following week. (Unfortunately, due to Hurricane Helene, I had to cancel those plans.)

The importance of a full field trial

This is something I always emphasize during presentations about SOTA, POTA, or traveling with radio: don’t assume your field kit is complete and fully functional—you must test it to know for sure.

A field test confirms two things:

  1. You have everything you need inside your kit to complete an activation.
  2. Everything in the kit actually works.

When preparing for something like a SOTA weekend or a family vacation, I usually deploy each of my field kits either at home or a local park. I power up the radio and make at least one contact, essentially mimicking a real activation. If everything works, I know the kit is good to go!

This simple process is an incredibly effective way to ensure your gear is ready for action.

Blue Ridge Parkway (US-3788)

That Wednesday, I squeezed in the activation between errands in town. The Folk Art Center near Highway 70 in East Asheville is the perfect spot—it’s a quick and easy detour.

Or at least it was before Helene. Now, with two bridges damaged—especially one major bridge on Highway 70—the two-minute detour to the Folk Art Center has turned into a 15-25 minute round trip, depending on traffic. (You never realize how essential bridges are until they’re gone!)

I parked near the picnic area, grabbed my gear, and headed for my usual picnic table setup spot.

Unfortunately, it was absolutely crawling with ants—likely a result of spilled juice or food. I moved to the other picnic table in the same area.

Testing the MTR-3B Kit in Real-Time

In the video, you’ll see me use every piece of gear in the field kit, except for the “bare bones” arborist throw line and weight. Since I had my other Weaver throw line kit with me, I used it to save time. I’d recently tested and re-packed the throw line in the MTR-3B kit, so I already knew it was in working order.

Setup was quick and easy. Once I connected the antenna and powered up the radio, I used my N6ARA Tiny SWR Meter to confirm I had a good match—since the MTR-3B LCD lacks an SWR meter. Fortunately, I had a perfect impedance match.

Time to play radio!

Testing New POTA Gear: High-Band QMX, Explorer Carbon Fiber Mast, Pressure Paddle, and a Packed Nemo Resolve 25L

7 Comments

Please note that this POTA (Parks On The Air) activation took place on September 19, 2024—eight days before Hurricane Helene devastated western North Carolina. This is one of a few field reports and activation videos I’ll be sharing that took place before Helene’s arrival.

As I mentioned in my last field report, I haven’t been back to the Vance State Historic Site since the storm, as it’s been closed. Located in the Reems Creek valley, the site likely experienced extensive flooding. I hope this park can recover and reopen soon.

I hope you enjoy this field report and activation video. I’ve thoroughly enjoyed reliving it while preparing this for you.

Thank you!

On Thursday, September 19, 2024, I made time for a POTA activation at the Zebulon Vance Birthplace (US-6856) and brought along a few new items to make it even more interesting.

New Pack

I packed my new gear along with extra equipment to fill out my new Nemo Resolve 25L backpack (check it out in gear links below). I wanted to see how well it could handle a full load and how comfortable it would be to carry.

Turns out, it’s very comfortable, and I could easily fit more in this pack than I’d likely ever need. It’s a keeper.

New QMX

First, I brought along a new QRP Labs QMX transceiver. If you’ve been a long-time reader, you’ll know I’ve had a QMX for about a year and think it’s a brilliant little radio. This one, however, is the “high band” version, meaning it covers 20-10 meters. My other QMX is the “low band” version, covering 80-20 meters.

As soon as the high band QMX was announced by QRP Labs, I grabbed one. I purchased an assembled version, knowing it could be a year (or much longer) before I’d have time to actually build one.

When I received this new QMX—I’m not sure, months ago?—I tucked it away in a drawer while reorganizing my shack, then promptly forgot about it (in my defense, I had a crazy year). I eventually rediscovered it, and here we are!

I’d been looking forward to taking it to the field.

New Carbon Fiber Mast

At Hamvention this year (2024), I ran into my good friend Mike Roberge (KE8PTX). He told me he was super excited about a new product that had been showcased—not a flagship radio or similar, but the Explorer POTA20Carbon Fiber Mast. 

Mike was one of the very few people who actually purchased one at Hamvention to take home. I believe Gigaparts only had two or three on hand—mainly for demo—so everyone else had to place an order and wait 6-8 weeks for the first shipment.

Meanwhile, Mike, being the clever fellow he is, designed a 3D-printed ground spike holder that fits a tent stake. This allows the user to unscrew the base cap of the Explorer mast, insert Mike’s ground spike, and support the mast without needing guy wires, etc.

If this sounds familiar, it’s because Mike made a video about how easy it is to deploy the Explorer mast with his ground spike.

I purchased my Explorer pole via Gigapart’s online store during or right after Hamvention. I didn’t receive my mast until sometime in August. This activation was the first time I tried it out in the field.

I deployed my 20M EFHW (built on a TennTennas transformer) by attaching one end to the tip of the Explorer pole, then sloping it down so the feedpoint was close to the edge of the picnic shelter at Vance.

K3ES’s Grippy Pressure Paddle

Another item I rediscovered in September was a VK3IL pressure paddle my good friend Brian (K3ES) gave me at Four Days in May during Hamvention. His version is a standard VK3IL pressure paddle, but with some padded material under the heat shrink, making it easier for big hands to grip.

Brian’s paddle paired nicely with the QMX!

With everything set up, it was time to hit the air.

The QMX, of course, performed well during this activation.

I did encounter some difficulties at the beginning when the QMX produced significant audio pops in the CW sidetone audio whenever I keyed the radio. I spent a few minutes troubleshooting and even changed speakers, thinking it might have been an issue with the Soundcore Mini.

It turned out to be related to toggling the AGC function. I eventually managed to resolve the audio pops and used the Soundcore Mini. I’m not sure I could replicate the process exactly, but I got it working. (If you’ve had a similar experience, I’d love your input.)

Otherwise, the activation went very smoothly.

I worked my first ten stations in eight minutes—woot!

Activity slowed down a bit after the first ten, but I still managed to work 17 stations in under half an hour.

Many thanks to everyone who hunted me!

Here’s what this five-watt activation looked like when plotted out on a QSO Map:

Here’s my real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

Note that Patreon supporters can watch and even download this video 100% ad-free through Vimeo on my Patreon page:

Explorer Carbon Fiber Mast

I love that the Explorer mast fits easily in my Nemo backpack. I see myself using it a lot for SOTA and POTA activations where suspending an antenna in a tree isn’t possible.

It’s super lightweight and compact, and Mike’s ingenious tent stake spike mod makes this mast so easy to deploy.

I also enjoyed using Brian’s pressure paddle during this activation—thank you, OM! It’s comfortable to grip and use.

This high-band QMX will make a brilliant SOTA transceiver. I need to take advantage of these high bands while the ionosphere supports them this solar cycle!

Thank you

Thank you for joining me during this activation!
I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!

Also, thank you for all of your recent support and kind messages following Hurricane Helene.

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon, and the Coffee Fund. While not a requirement, as my content will always be free, I really appreciate the support.

Thanks for spending part of your day with me!

Cheers & 72,

The POTA Babe Donates Blood at Congaree Bluffs Park

2 Comments
By Teri KO4WFP

In my last article, I activated Hanging Rock Battleground State Historic Site and then Glenn and I spent the evening at an Airbnb in Camden, South Carolina. Monday, October 14th was the last day of our trip. There was no way this POTA Babe was missing out on an activation on the trip home.

Sunday evening, after the Hanging Rock activation, I searched for a nearby park on the POTA website and settled on Wateree River Heritage Preserve Wildlife Management Area (WMA) (US-10414) as it looked interesting and was on the drive home. However, I didn’t pay attention to the fact a lottery deer hunt would be held on Monday and the park closed to anyone not involved in the hunt. I discovered this fact that morning upon arriving at the site. It was time for a Plan B ASAP.

Looking on the POTA website, both Congaree National Park (US-0017) and Congaree Bluffs Heritage Preserve WMA (US-3916) were nearby. I recall reading that some of the boardwalks/trails in the national park were impacted from Hurricane Helene.  So I opted to visit Congaree Bluffs instead.

Congaree Bluffs Heritage Preserve is owned by the State of South Carolina. The property was purchased in 2001 with the express purpose of protecting the bluffs and flood plain on the south side of the Congaree River. The high bluffs in this area are not common because central South Carolina is mostly flat. The 201 acres of the park contain significant stands of American beech, oak-hickory, and bottomland hardwood forest. There were also stands of loblolly pines at the time of purchase that management planned to convert to longleaf pine stands over time.

The road into Congaree Bluffs is dirt but appears well maintained. There is a kiosk and signage just as you enter the park.

dirt access road – Turkey Track Lane (what a great name!)

We drove to the parking lot just down the road from the education center. I didn’t have much familiarity with this park since it was a last minute choice. A hasty glance at hiking sites showed the Bluff-River Walk that left from this parking lot down to the Congaree River.  How difficult could that be?

entrance for Bluff-River Walk

Glenn and I walked around the trail gate and began our descent. The first thing we noticed was how many trees were down across the trail as well as vines and other foliage making passage difficult. As we continued our descent, we began to notice the mosquitos. I was wearing long sleeves and pants and had brought bug spray but these mosquitos were not easily deterred. By the time we reached the river, it was obvious we’d be nothing but blood donors there and an activation needed to happen elsewhere.

Arriving back at the car, I opted to activate in the parking lot. A stand of pines nearby provided shade (though I augmented that with my Mountain Laurel Designs tarp) and a fairly steady breeze kept the bugs at bay.

As both Glenn and I had CW Innovations classes to coach later that evening, I didn’t have much time for an activation. I opted for the Chelegance MC-750 and, once it was set up, hopped onto 20 meters figuring that band would give me the best chance at a successful activation in a short time-frame. It did! I had 23 QSOs with two park-to-park QSOs in 30 minutes. (Note: One park-to-park didn’t count after the fact as I entered it incorrectly in my log.)

The only fly in the ointment for my time on 20 meters was the QSB and noise which increased later in the activation. Usually I encounter noise on 40 meters, not 20, but the KX2 filters were a huge help in countering that issue. (I love that little rig!) As for the QSB, well, the best counter for that is plenty of time on the air to gain experience in dealing with it.

If you’d like to see footage of the park as well as get Glenn’s and my take as to whether or not we’d return to Congaree Bluffs Heritage Preserve, check out the video on my Youtube channel.

This activation places me at 44 activations toward my goal of 60 new, valid park activations for 2024. I’m not sure I’ll be able to complete this goal; however, I will see how far I can get. Where will I show up for park #45? Stay tuned…

Uncompromised Performance: Taking my new-to-me Ten-Tec Argonaut VI to the field!

9 Comments

In late August 2024, I came across what I considered a great deal on a fantastic radio, which I’m excited to share with you in the following field report.

Please note that this POTA (Parks On The Air) activation took place on September 5, 2024 (almost exactly two months ago)—three weeks before Hurricane Helene devastated western North Carolina. This is one of a few field reports and activation videos I’ll be sharing that took place before Helene’s arrival.

I haven’t been back to the Vance State Historic Site since the storm, as it’s been closed. Located in the Reems Creek valley, the site likely experienced extensive flooding. I hope this park can recover and reopen soon.

I hope you enjoy this field report and activation video. I’ve thoroughly enjoyed reliving it while preparing this for you.

Reunited with the Model 539

In late August, I was browsing the QTH.com classifieds when I spotted a radio I hadn’t seen for sale in some time: the Ten-Tec Argonaut VI QRP transceiver. This radio had been on my mental watchlist for years.

The seller was asking $440, which I considered a great deal for a radio that, to my knowledge, hasn’t been in production since Ten-Tec closed its Sevierville, TN factory in 2016.

This radio and I have some history together. I was one of the original volunteer Beta testers for the Argonaut VI and, in 2012, wrote a full review of the production model.

Ten-Tec offered me a chance to purchase my Beta unit (updated to full production specs) with a modest discount. But at the time, I simply couldn’t afford it; we’d just built our house, and I couldn’t justify the purchase, especially since I’d also reviewed and bought my Elecraft KX3 that same year.

I always planned to get an Argonaut VI eventually—better late than never, right?

As I mention in my activation video, I plan to make a “Getting to Know You” video for the Argonaut VI soon, so I won’t dive deep into why I love this radio here.

The takeaway? I feel the Argonaut VI has some of the best overall receiver performance of any radio I’ve used. It’s quirky and certainly not perfect, but its excellent receiver, filtering, audio, and QSK make it a benchmark QRP transceiver.

Getting Reacquainted

While the Argo VI was en route to my QTH, I wanted to refresh my memory on its operation.

Since it had been twelve years since I last used the Argonaut VI, I had to revisit my own review to remember some of its nuances!

When it arrived, I quickly put it on the air and operated it from my shack until I had a chance to take it to the field on Thursday, September 5, 2024.

Vance Historic Birthplace (US-6856)

As I always do with smaller POTA sites like Vance, I called ahead to make sure the picnic shelter wouldn’t be reserved at my arrival time. The park ranger replied, “It’s all yours, Thomas!”

The weather was nearly perfect that Thursday, with a hint of fall in the air.

En route to the site, I thought about my antenna options. Since the Argo VI doesn’t have a built-in ATU, I opted to use a resonant antenna for simplicity. In the end, I chose my Chelegance MC-750 vertical, which I set up next to the picnic shelter.

The MC-750 is a quarter-wave antenna, so I extended the telescoping whip for a match on the 20-meter band.

I don’t yet have a field kit specifically built around the Argonaut VI, so I simply brought along various accessories in my Husky weathertight storage box.

I set up the radio, tuned to 20 meters, checked my settings, and was ready to take the Argo VI on its first POTA activation!

My First Post-Helene POTA Activation!

13 Comments

On Friday, October 24, 2024, I performed my first POTA activation exactly one month (to the day) after Hurricane Helene swept through western North Carolina.

It felt oh so good!

As many of you know who’ve been following my Post-Helene updates, I simply haven’t had time to do POTA or SOTA activations. And even if I wanted to, most of the POTA sites around me are temporarily closed due to damage from Helene.

Truthfully, I didn’t start my day expecting a POTA activation. I’d planned, if anything, to make a short field radio video somewhere on my property, chase some POTA/SOTA stations, and make any other random contacts.

However, my daughter’s Shakespeare class decided to meet in person, so after dropping her off at 12:30, I had about two hours of free time. Before leaving home, I packed a couple of radio bags just in case I could find a spot for a POTA activation, or at least visit a local park to play radio for a bit.

I realized I was only a 20-minute drive from the Sycamore Flats picnic site in Pisgah National Forest (US-4510), where I’ve activated many times before. This site is in Transylvania County, which wasn’t hit as hard by Helene.

Google Maps showed the site as open, so I decided to drive over. Thankfully, it was correct! When I arrived, the front gate was open and there were a few visitors around.

I could tell the site had some storm damage—some tree limbs down and evidence of flooding from the Davidson River, which wraps around the area. The park service recently upgraded the picnic table pads, but the gravel had washed away, and many tables had either shifted or washed away.

That said, this site fared well compared to parks in Buncombe County. (Chimney Rock State Park is still inaccessible due to major flooding in the town of Chimney Rock.)

I hopped out, grabbed my backpack and TR-45L, and started recording my activation video.

Since no one was using the picnic shelter at the northeast end of the park (and it had no reservation sign), I set up there. I deployed my MM0OPX End-Fed Half-Wave antenna on a nearby tree, connected it to my TR-45L, and was ready to go!

Two in One Day for the POTA Babe

4 Comments
by Teri KO4WFP

After striking out at Pinckney Island National Wildlife Refuge, it was time for this POTA Babe to get back on track with my goal of 60 new valid park activations for 2024. As much as I enjoyed the historic sites and the refuge I recently visited, I needed to return to activating wildlife management areas.

Wildlife management areas (WMAs), properties set aside for conservation as well as hunting and fishing, are plentiful in the state of Georgia. Georgia has 163 WMAs and 38 are located within 75 miles of my home QTH. So it makes sense I would include those in my 60 new activations pursuit.

I set my sights on Morgan Lake WMA (US-9791) and Griffin Ridge WMA (US-3752) because  they are an hour’s drive from my home and across the road from one another. Talk about convenient!

map source: worldatlas.com

Daisy and I set out early Tuesday, October 1st. During the drive, I encountered two groups of ambulances moving north on Interstate 95. At a rest stop, several EMTs from one group were taking a quick break and wore t-shirts with “Disaster Relief” on them. It was a reminder of the recent events due to Hurricane Helene.

I chose to activate Morgan Lake WMA first.  According to the map, most of the property appeared to be wetlands but there is a boat landing for fisherman to access Morgan Lake. In fact, the road you use to reach the landing is built up a good 10-12 feet, I assume, to provide access even when the area experiences flooding.

boat landing and train trestle bridge

WMAs vary in their presentation. Some are nicer than others with shooting ranges and gravel roads. Morgan Lake was, frankly, on the dumpier side. This was not the place to come to commune with nature. But no matter. I was here to do an activation, so I set about getting my equipment up and running.

I opted for the Chelegance MC-750 today. Attempting two parks in one day meant I needed a quick and easy set up and a vertical would provide that.

Despite poor band conditions at some of my past activations, today the bands were great! (You’d really want that on a day you are attempting back-to-back activations.) Even better, I had internet access at this park, though it was on the slow side. I could spot myself (always a plus) and it wasn’t long before calls began coming in once I was spotted on the POTA website.

Forty meters gave me 15 contacts in 20 minutes – not bad! It was good to hear so many from the southeast, some I hadn’t heard from in a while. Given I had a second activation to attempt and I wasn’t thrilled with the site conditions at Morgan Lake, I called QRT after contact #15, packed up, and headed across the road to Griffin Ridge WMA.

Griffin Ridge is a much larger WMA than Morgan Lake. The park has two access points from the road and I chose the one farther to the north as it looked the more inviting of the two.

Map for Griffin Lake WMA. source: GA DNR

Again, given I was short on time today, I found a little area off to the side near the information kiosk by the road. If I visit this WMA again, I’ll drive further in and find a place away from the road noise.

The little place I found was somewhat shaded which Daisy and I needed given the warm weather. The day had been mostly overcast; however, I’ve learned to not trust that will persist. Nothing like being in the middle of an activation and the sun comes out from the behind the clouds to roast you.

the spot I found just perfect for parking Kai

For the North Carolina trip this past July, I purchased a Mountain Laurel Designs shelter. It was handy for my SOTA activation at Black Balsam Knob. I figured it would also be useful for POTA activations in the heat. Since I can activate next to my car for POTA, I used the front and rear wiper blades as well as the roof rack to attach three sides of the tent and the surrounding foliage to which to attach the other two. My hiking pole was not tall enough to support the center, so I used the outer rear door handle on the car to elevate the bottom of the pole to give me enough height so I could sit in my Helinox chair under the tent. It was not the best setup but good enough for today. I need to give more thought how to better support and use the tent as a shelter with my car.

Daisy relaxing

We all know band conditions fluctuate throughout the day and I hoped they would hold up for my second activation. Guess what? They did!!!

I opted for 20 meters given it was nearly noon and had 39 contacts in a little over an hour. I was thrilled! That is a “good” thing about bad band conditions. When the bands behave, you really, REALLY appreciate it.

view from under the tent at my QTH

As I packed up my equipment, I reflected on the two activations. Of the two, I would return to Griffin Ridge. The foliage and landscape reminded me of Canoochee Sandhills WMA; however, it was nicer than Canoochee and not nearly as remote, which could be considered bad or good, depending on your perspective. I would definitely set up farther inside the property to avoid the road noise unless it had rained a lot prior to my visit. The road into the property was quite sandy and soft and deep in some spots. My car might not be able to navigate those conditions after a heavy rain.

A valid activation at these two parks put me at 41 out of the 60 new park activations for which I am aiming in 2024. There are only three more months of this year so I am running out of time to reach my goal. It would be easy to accomplish my goal if life didn’t keep getting in the way, right?

There are still plenty of wildlife management areas to consider as well as properties closer to the coast as I continue my pursuit. Where will I show up next? Stay tuned…

QRP POTA: Pairing N3CZ’s Homebrew Transceiver with the TennTennas 49:1 EFHW!

2 Comments

On Monday, September 2, 2024, my good friend Vlado (N3CZ) and I spent Labor Day morning playing POTA.

Our first activation was at Lake James State Park, using the new CFT1 QRP transceiver. It was a lot of fun–you can read the field report and watch the video by clicking here.

For the second activation, I wanted to take Vlado to a site I’ve activated numerous times—one of my favorites—that he had yet to visit:

Table Rock State Fish Hatchery (US-8012)

We arrived on-site around 11:00 AM and, no surprise, had the place to ourselves. Honestly, I was hoping we’d see the three dogs that often pop by for a visit, but I believe they were on vacation with everyone else!

We both figured 20 meters would be our bread-and-butter band for this activation. More importantly, our transceiver was a 20-meter monoband (more on that below), so I deployed my new 20-meter end-fed half-wave antenna.

This particular EFHW is built on a  transformer by Walter (NE4TN) at TennTennas.

TennTennas 49:1 QRP Transformer

I may have mentioned before that Walter gave me this little 49:1 transformer at Hamvention this year when I met him in person. Walter is one of my top hunters in POTA, and I can often count on hearing his call when I’m on 40 meters.

Walter handed me this little transformer as a thank you, with no obligation to promote it—in fact, he didn’t even tell me where they could be purchased.

But I’m a sucker for home-grown mom-and-pop ham radio businesses, so of course, I’m going to plug it! He sells these on eBay (partnership link) for $39 each as a small side business. Not a bad price for a solid little 49:1!

As I mentioned, I trimmed this one for 20 meters, but I’ll likely make it a linked antenna with 30 and/or 40 meters as well someday.

Vlado’s Homebrew Transceiver

I was also excited that Vlado brought along his homebrew 20-meter QRP transceiver.

I had seen this radio in his shack during various stages of development, but I had never had an opportunity to use it in the field.

I’m not sure if Vlado had used it for a POTA activation yet, in fact.

His little transceiver is super simple but sports proper filtering, an OLED display, and, despite the large battery he connected to it, has modest power requirements.

He built it into an old Kenwood VHF radio chassis he found at a hamfest. I’ve been with Vlado before when he’s hunted for chassis for his various homebrew projects. The OM is always building or repairing something in his shack.

We were really looking forward to putting this little transceiver on the air!

The POTA Babe Spreads Her Wings at Pinckney Island

1 Comment
by Teri KO4WFP

Friday, September 13th, I headed to Pinckney Island National Wildlife Refuge (US-0265) for a POTA activation and was without Daisy as dogs are not allowed at this refuge. Pinckney Island is a 4,000+ acre wildlife refuge off Highway US 278 on the way to Hilton Head Island, South Carolina. The refuge consists of four islands and numerous small hammocks with Pinckney Island being the largest of the islands and the only one open to the public.

The refuge is named after Major General Charles Cotesworth Pinckney and is one of seven refuges managed by the Savannah Coastal Refuges Complex in Savannah, Georgia. Prior to my time as a ham radio operator, I volunteered for the US Fish and Wildlife Service and spent time at four – Savannah, Harris Neck, Wassaw Island, and Blackbeard Island – out of the seven refuges they manage. I never made it to Pinckney Island so I was excited to finally see this property.

Most of Pinckney Island is accessible by foot or bicycle only. After parking my car in the designated lot, I began hiking to my destination – Ibis Pond, a large pond for waterfowl about a mile from the parking lot.

Just before I reached the information kiosk, I got a great look at an armadillo doing what most gardeners and lawn aficionados hate – tearing up the ground in search of food. This mammal eats mostly invertebrates including insects and especially likes grubs. They have horrible eyesight but keen hearing and I was surprised this guy or gal let me get as close as he or she did.

Pinckney island is an important link in the chain of wildlife refuges along the Atlantic Flyway and attracts thousands of migratory birds each year, according to the US Fish and Wildlife Service. The Atlantic Flyway is a major north-south route for migratory birds and it generally follows the Atlantic Coast of the US.

I saw and heard many birds while visiting the refuge including a flock of White Ibis feeding in the marsh and tidal flats, a Great Blue Heron fishing with a Snowy Egret walking nearby, American Coots, a molting male Painted Bunting, crows flying overhead, and I swear I heard a pair of Sandhill Cranes calling to one another at Ibis Pond. I could have spent all day watching the comings and goings of the refuge inhabitants let alone do a POTA activation.

However, I was here for POTA and, in short order, arrived at Ibis Pond. It is one of five manmade ponds on the island and exists to preserve feeding and nesting areas for birds. The pond has cattails around its edges and much of the water is covered by duckweed.  I figured I would be less likely to have any human visitors if I followed the trail around the pond to the far side. But I was wrong. Ten to twelve people walked by my station while there, more than I usually encounter at any park. Continue reading The POTA Babe Spreads Her Wings at Pinckney Island →

Xiegu X6200: Does version 1.0.1 firmware fix CW keyer timing?

8 Comments

I’ve had a production unit of the Xiegu X6200 since June of this year and have made several field reports using it for both SSB and CW.

You may have noticed, though, that I haven’t used it much in the field since June.

The reason? I’m primarily a CW operator, and the original firmware had some frustrating CW keyer timing issues.

These keying issues are most noticeable when operating in iambic mode, especially when trying to form letters like C, R, or K by squeezing the paddles. Often, when I try to send a “C,” as in “CQ,” the keyer produces a “B” instead. If you’ve watched any of my previous X6200 videos, you might have seen this happen a few times.

After some time using the radio, I can adapt and reduce the miskeying, but it still happens occasionally. I suspect part of the issue is related to the keyer timing in relation to the transmit/receive switching.

While these keyer issues aren’t severe enough to prevent me from completing an activation, they are certainly annoying.

As I’m reviewing the X6200 (thanks to Radioddity for the extended loan!), I reported the issue to Xiegu back in May and hoped the first firmware update would address it.

The first firmware update, Version 1.0.1, was released in early August. There was an earlier release, but it was retracted due to other issues.

I checked the release notes and didn’t see anything specific about CW keyer timing in the long list of fixes. I had hoped another update would follow soon, but none has been issued yet. Meanwhile, several readers and subscribers have asked me if the keyer issue was resolved.

I decided to update the firmware and take the X6200 out for another field test.

If you follow QRPer.com daily, you may have already seen the spoiler alert: unfortunately, the keyer timing issue was not fixed in this release.

Still, I had a great time squeezing in a quick activation with the X6200, and I thought I’d share the video and a mini field report with you now!

Pisgah National Forest (US-4510)

My wife and I were out while one of our daughters was in Shakespeare rehearsals in Mills River, NC on Friday September 6, 2024. We had a number of errands to run, but my wife kindly worked with me to carve out 30 minutes for a quick activation.

The most convenient POTA location was the Sycamore Flats Picnic Area in Pisgah National Forest.

By mid-afternoon, the park was busy, but most of the picnic areas were open, giving me plenty of options for setting up.

With limited time, I turned on the camera to start my real-time, real-life activation video and got straight to work.

Since the X6200 has a built-in ATU, I decided to use my PackTenna End-Fed Random Wire, as it’s quick to deploy with its 31’ long radiator—any nearby tree would do.

Next, I paired the X6200 with my BaMaKeY TP-III, plugged in the antenna, and found a spot on the band to start operating!

Time to POTA!

On The Air

After tuning up on the 20-meter band, I spotted myself and started calling CQ POTA. Fortunately, hunters quickly responded.

In just twelve minutes, I logged thirteen contacts. Thanks to all the hunters!

My activation was brief, and I was so focused on making contacts and packing up that I forgot to take any photos of the radio in action. I’ve included some screen captures from the video instead.

I did manage to take photos of the logs:

Here’s what this five-watt activation looked like when plotted out on a QSO Map:

Activation Video

Here’s my real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

Note that Patreon supporters can watch and even download this video 100% ad-free through Vimeo on my Patreon page:

CW Keyer Timing

As I discovered during this activation, the CW keyer timing issue has not yet been addressed in the firmware update.

After returning home, I made some notes and reached out to Xiegu to confirm that the CW keyer timing is still on their radar. They assured me that it will be addressed in the next firmware update. I’ll definitely test it and let you know once it’s resolved, so stay tuned!

If you’ve already purchased an X6200, I’d love to hear your thoughts about this all-in-one radio in the comments!

Thank you

Thank you for joining me during this short activation!

I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon, and the Coffee Fund. While not a requirement, as my content will always be free, I really appreciate the support.

As I mentioned before, the Patreon platform connected to Vimeo makes it possible for me to share videos that are not only 100% ad-free but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me! Have a brilliant weekend!

Cheers & 72,

CFT1 QRP: Labor Day Morning POTA with Vlado at Lake James State Park!

2 Comments

Labor Day weekend turned out to be full of labor here at QTH K4SWL. My wife and I had numerous projects to tackle, and my daughters had various activities scheduled as well. By Sunday, my wife looked at me and said, “You need a break. Why not spend tomorrow catching up on POTA?”

That was music to my ears.

I messaged my buddy, Vlado, to see if he might be interested in joining me, and he quickly replied, “Of course!”

So on Monday, September 2, 2024, Vlado packed his radio gear in my car, and we discussed where we should go. We had most of the day for radio, but we needed to decide if we’d head north, south, east, or west. In the end, we chose to travel east, as it offered the most options, including one site Vlado had never activated.

We decided to start at Lake James State Park. Since Vlado had only activated Lake James for the first time the previous day at the Paddy’s Creek Access, we opted for the Catawba River Access.

Lake James State Park (US-2739)

It was Labor Day, so we knew Lake James would get busy around lunchtime, which is why we hit it early. I also knew Paddy’s Creek Access would be much busier today because it has the beach, and I remembered how full the parking lot was during my Labor Day activation in 2023!

At 9:00 AM, when Vlado and I arrived at the Catawba River access, we were among the few people there, so we had our pick of spots to set up the POTA station.

For convenience—especially since there had been a deluge of rain the night before—we chose a spot close to the car, where I’ve activated a number of times in the past.

I also took this opportunity to show Vlado how to use an arborist throw line.

While I didn’t record the antenna deployment—frankly, I didn’t think about it at the time—I wish I had. Vlado was a natural!

On his second-ever throw, he snagged the perfect branch to deploy a 40-meter end-fed half-wave antenna.

CFT1 Time!

The CFT1 with Tufteln cover/stand, audio cable and pack with battery.

I knew exactly which radio I wanted to operate during this activation: the CFT1 by Jonathan (KM4CFT).

I had only recently swapped out my Beta unit for a production CFT1. As a thank-you to Beta testers, Jonathan let us keep the units we tested. I worked with Jonathan and Dan to return the Beta unit and compensate them for the difference.

In truth, there were only a few changes, mostly cosmetic, between the Beta and production units. The biggest improvement for me was that the Beta unit lacked a way to adjust the sidetone level independently from the AF gain. The production unit has this feature, which was my primary motivation for upgrading.

In addition, I prefer using radios that match what my readers and subscribers have. When I use a Beta unit, even if the changes are purely cosmetic, it generates more questions.

Interestingly, this wouldn’t be Vlado’s first time using the CFT1. He must have been one of the first people outside the Beta testing team to try it because we used it on Field Day alongside the TR-45L and X6200 (although you won’t see it in my report since it was still somewhat of a secret project at the time).

We paired my MW0SAW 40-meter EFHW and Bamakey TP-III with the CFT1. I also used my Anker Soundcore Mini speaker for audio.

Time to POTA!

On The Air

Beforehand, Vlado and I decided to set up just one station and take turns activating.

Vlado went first! He called CQ POTA, and hunters started replying. Continue reading CFT1 QRP: Labor Day Morning POTA with Vlado at Lake James State Park! →
