Kansas City to the Countryside: N5DUX’s Work Trip POTA Journey

Work Trip POTA

by Tommy (N5DUX)

I recently had a work trip that took me to lovely Emporia, Kansas – home of Emporia State University. Prior to leaving for the trip, I did a little POTA sleuthing to see if there were any parks in the general region I could activate after I finished work each day. As luck would have it, I found there were indeed a handful locations on the POTA map within a reasonable drive – including one right in town!

One of the locations was a fun looking site called the Tallgrass Prairie Preserve National Conservation Area (US-3673), home to a herd of bison.

Viewing on Google Maps I saw a “scenic lookout” in the middle of the prairie and figured that sounded like a great place to setup.

Packing my suitcase for the trip (there’s work to do, remember!) I included my Buddistick and a collapsable, “450cm” carbon fiber fishing rod. The rest of my kit was in a hand held bag that I would carry with me. My main radio for this activation was my Elecraft KX2.

For an antenna, I brought my a newly built 20W K6ARK EFHW trimmed which I had tuned to work on 40m, 20m, and 10m with the idea of using the fishing pole to hold up the far end of my end-fed. Should that fail or disappoint, I had my Buddistick which is self-supporting thanks to the excellent design of its shock-cord tripod and “tie-down” to keep the whole thing upright in strong winds.

Included in my bag was a 9Ah Bioenno battery, reel of kite string, a throwing weight, notebook for logging, pencil, Elecraft hand mic, Elecraft paddles, some earbuds, and a few other insignificant odds and ends (adapters, pigtails, etc)

When packing radio equipment in your suitcase, remember to not pack any batteries in your checked bag. For carry-on, remember to not pack any pointed objects like tent stakes, screw drivers, or spikes like some vertical antennas like the Chelegence 750 or PAC-12 have. Pack smart – think about what the radio will look like to someone unfamiliar with our hobby.

TSA really doesn’t care about our radios or wires – they just don’t want bricks of organic material surrounded by wires on the plane or sharp pointy things in the cabin.

On Easter Sunday, I flew into Kansas City, picked up a rental car, got a quick bite of BBQ recommended by the guy at the rental car place, and set off. The weather upon arrival was excellent. A nice breeze, sun shining, and warm temps. Lovely. But the weather forecast had told me it wouldn’t last.

While at work on Monday, the temperature began its steady slide as a cold front moved through the area. As soon as the work day was finished, I quickly changed clothes and headed west of Emporia for the Tallgrass Prairie Nature Preserve.

The weather continued to get cooler and the wind had picked up.

As soon as I arrived, I was greeted by a park ranger leaving. I asked about the bison herd and he told me the scenic overlook I’d picked as my destination was a couple miles down a gravel trail. I ask the ranger if he knew about ham radio and he said there was a group coming in a couple months or something but said I was welcome to setup wherever I pleased. I grabbed my gear, preparing to make the 2 mile hike, and started down the path.

I got about a quarter mile in and cresting the first grassy rise, I realized I’d underestimated just how strong the wind really was and how cold it was going to get if I stayed exposed. I had not worn my thicker coat and realized I wouldn’t last long on the prairie given my attire and the weather to come. Seeing the bison would have to wait.

I changed course and walked back to a historic ranch situated on the property with some still-used cattle pens. Surveying my options there, I spotted a shelter for the livestock over in the corner of one corral. Eyeing the grassy area in that pen, I decided that was going to be my operating position. No sooner had I chosen my spot when I heard the faintest tick of raindrops hitting the tin roof.

I unfolded my chair in the dirt under the roof then unpacked my radio, pencil, logbook, some trail mix (nabbed from the hotel front desk snack bin), and my water bottle. I unspooled the EFHW and erected the fishing pole to hold up the far end. I connected the antenna and let the Elecraft KX2’s internal tuner do its thing. It found a 1:1 match in no time and everything was set.

Shack in the lap with the KX2.

I dialed through the band to get a sense of conditions on 20m. I listened to a few other POTA stations and was able to work them. I then found an unused frequency, called out, and listened. Nothing heard – I was ready to go. By this point, it was only about 30 minutes total since my arrival – not too bad.

I spotted myself on the POTA site and my first hunter responded to my CQ pretty quickly. This trend continued unabated for quite some time.

When there was a lull in activity, I grabbed a handful of trail mix and was mid-chew when someone called. I tried to swallow and got choked. He’s calling me. I’m trying to clear my throat. Nobody’s around – the best I could muster was a half-wheezy reply to his call. He probably thought my signal dropped a few dB – no old man, it was my voice. A splash of water after we were clear and I was back to normal.

Around this time, the raindrops decided to spit a little and the wind had definitely picked up. I adjusted my antenna to see if that helped matters. I used my kite string to secure one end of my wire antenna to the stone wall surrounding the pen and moved the fishing pole support from the end near the wall more toward the middle This gave the antenna more of an inverted V configuration.

It actually helped! Whereas before my “sloper” was more of a “sagger”, I actually got an increase in the relative frequency of QSOs. I worked with this configuration for the rest of my stay at the preserve. The wind never let up and the temps continued to slide. I was shivering by the time I finished packing up and the sun had set and darkness was setting in.

Back to the rental car and heater, please!

Tuesday brought a similar workday but I planned to activate a historic home there in town after enjoying a dinner at a local restaurant recommended by my hosts. The weather was considerably colder than Monday and it was downright windy. I’m glad I’d worked the nature preserve on Monday and didn’t wait to try on Tuesday!

Rental car portable at the William Allen White House known as “Red Rocks” in Emporia, Kansas

I made my way over to the William Allen White House State Historic Site (US-9183) a few blocks from the university and the dinner spot. With the weather as it was, I opted to sit in the rental car and run my antenna out the top of a cracked window over a couple low branches and over to another large tree branch. I got my rig setup in the car for my first “rental car portable” activation and found it to be considerably more comfortable than the night before. I managed to log about 20 QSOs in short order on 20m until band conditions deteriorated.

On Wednesday, we wrapped up the work project that had brought me to town. We had a final wrap-up meeting with my point of contact there and I headed back to Kansas City. The intent was to grab a quick dinner with a friend, head for the hotel, throw down my stuff and make for the World War I Museum National Memorial (US-4591). The dinner lasted much longer than I’d planned but it was okay. Dinner was with my CO whom I hadn’t seen since I was in the Guard.

We shared a great dinner with his wife, recounting funny stories from our times together and generally getting caught up. I didn’t get to the hotel until very late so I decided I better get some shut-eye and just activate the Museum and Memorial in the morning.

Thursday morning, I packed up everything to get ready for the airport.

My plan for the WW1 Memorial was to find a tree and throw the EFHW there and get some sun while sitting at a park bench or something. It didn’t happen. The strong, cold wind continued. I opted for another “rental car portable” operation. Noticing my “sloper” was again a “sagger,” I pulled the fishing pole out of my suitcase and elevated the antenna wire in the middle. Much better.

Band conditions on 20m were rapidly going down the drain and it was hard for me to hear anyone – the big guns that I worked toward the end of my activation provided such poor signal reports, I knew my QRP signal just couldn’t compete with the noise floor that continued to come up.

In total, I managed to bag about 14 QSOs in short order – but it was enough to count as another activation! And, since this was on the Missouri side of Kansas City, it gave me a new state.

I packed up, grabbed some more famous Kansas City BBQ at another local haunt, and headed for the airport to fly home.

The reliable, trusted Buddistick surprisingly never saw the light of day on this trip. It sure was along for the ride, but the EFHW really worked well and I enjoyed the simplicity of it when it came time to pack up. Being less of a compromise antenna led me to believe it would be more efficient anyway.

I’m still somewhat new to POTA and I continue to learn – but this was a memorable work trip because I brought my radio along with me and it took me to some spots I may not have otherwise ventured to visit. The work that brought me to the university went well enough that we began scheduling a return trip slated for sometime in a couple months. I plan on bringing my radio with me for that and on all future work trips in other places.

Leap Year Day report from the Great White North

5 Comments

by Vince (VE6LK)

It seemed easy enough on paper. Famous last words, right?

It’s a leap year in 2024 and how many chances will I ever get to activate on February 29th, at least that was the reason for the multi-entity rove. That and the fact I hadn’t been up close to the mountains in at least a month despite living in close proximity.

The day before departure for #POTAThon240229 my heart sank when I saw the forecast of 4-8″ of snow. I’d already done my planning and secured most of the day off work. The plan was bold, including 3 National Parks and 2 National Heritage Areas in two provinces and would take about 9 hours to execute from end to end. I was also badly in need of some mountain therapy as it had been a couple of months since I’d been close-up to the Canadian Rockies. I went to bed not hopeful for the next day but kept an open (hopeful?) mind.

The next morning, the forecast had changed drastically and the snowfall had been cut in half; 2 to 4″ of snow is pretty normal this time of year and that means the roads are usually no problem, and yes that is a foreshadowing .. The route planned was to go out along the Trans-Canada Highway to Field, British Columbia, and work my way back towards home with stops along the way. A simple out-and-back as it were.

I hit the road and aimed the F-350 for Yoho National Park in Field B.C. where I snapped the photo below. Two-thirds of the way there, the roads turned terrible, and a two or three lane road was open with only a single lane. Whiteouts happened on and off and travel was Sierra Lima Oscar Whiskey, to say the least.

Pottymouth made some short inward appearances, mostly exclamations about my lack of luck. With conditions like this, the basic rules are to take your time and allow twice the following distance you think you need. “Why not turn around?” you ask? Because I was already two-thirds of the way to the endpoint, thus deeply invested in the travel and I figured it would not get much worse.

Mount Dennis as seen from Field B.C.

It didn’t get much worse, and arriving at the Field Visitor Centre, I was parked within 100′ of the Kicking Horse River National Heritage Area by being in the parking lot pictured above. In the summer months, this lot is jammed with cars and the view is stunning as you are in a narrow valley with a small town across the fast-moving river. It appears that the 2-4″ of fresh snow was more like 8″ as the parking lot had not yet been plowed and it was up past the chest of Red Wrangler the Shiba Inu.

Red Wrangler the Shiba Inu, totally within his element

The parking lot is at ~1225m (4045′) Above Sea Level and the mountains nearby are ~2400m (7920′) and are just about right beside the road. The narrow valley runs Northeast to Southwest so it for certain affects takeoff angles on any antenna. Given the temperatures were plus or minus the freezing point, I opted to stay in the cab of the truck for the day. I completed my activation 25 minutes later and started driving. At this point I’m close to 2 hours behind plan and I made the choice to visit Lake Louise and do a food stop, but not to activate.

Lake Louise, lakeside and pretty snowy

If you are wondering what Lake Louise looks like without 2′ of fresh snow, you can do that here with Google Street View. Even though I was behind plan, it was a must-do visit in order to refresh my soul and get some fresh mountain air.  Mister Dog and I made a quick trip to the lake’s edge and back to the truck to continue along with our day, as even if I had the time, I did not bring snow-clearing equipment -like a front-end loader- to clear off a park bench to set up!

About 45 minutes later, I crossed over the fifth mountain pass of the day and ended up in Kootenay National Park (CA-0045) at the Alberta/BC border on Highway 93. It’s a geographically unique spot as it is also at the Continental Divide. It was the third point of the Continental Divide I’d cross during the trip. At least by now the snow has stopped falling.

The Continental Divide at AB/BC Highway 93

Once again, I arrived to a fresh 8″ of snow in the unplowed parking lot and Wrangler was most pleased to cavort about and stretch his legs. At this point, I was surrounded by ~3100m and ~2600m mountains while sitting at ~1631m ASL. Again, a narrow valley with rocks on either side of me and, thanks to low-hanging clouds, I couldn’t see much of them at all, sigh.

I’ve travelled up and down this valley before so I know that, as long as I’m not right next to the rocks, my signal will be heard someplace. I’d learned first-hand just how much close proximity to the side of a mountain can impair your signal during my trip to Montana’s Glacier National Park last August. The noise floor and signals will drop out as you drive along beside the rocks and then comes back up as you move away from them even by 50′ or so.

SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit!

12 Comments

A few weeks ago, I mentioned that Jonathan (KM4CFT) sent me one of his new QRP end-fed half-wave/random wire antenna kits.

When my friend, Alan (W2AEW), caught wind that I planned to buy some 26AWG wire for this build, he sent me a spool of wire from a large reel he’d recently picked up at a hamfest.

What a nice guy! The blue wire is absolutely ideal for portable antennas.

Being the nice guy he is, Alan actually published a video about building Jonathan’s antenna kit on his YouTube channel. I highly recommend watching it!

Before I received the kit, I already knew what type of antenna I’d build: a 30 meter end-fed half-wave (EFHW) linked with a 40 meter extension. This antenna design has been on my mind for some time and Jonathan’s kit was the perfect excuse to build one.

Why a 30M EFHW with a 40M extension? Because a 40M EFHW gives me excellent SWR matches on 40, 20, 15, and 10 meters without needing an ATU.  A 30M EFHW gives me matches 30 and 17 meters.

Thus, with one linked wire antenna, I can cover 40, 30, 20, 17, 15, and 10 meters! That’s a lot of bands!

And since the antenna needs no extra matching, it’ll work with my transceivers that lack an internal ATU.

The Mountain Topper MTR-5B I acquired earlier this year.

In fact, I originally thought about this antenna design to use with my Mountain Topper MTR-5B which covers 40, 30, 20, 17, and 15 meters.

I built this antenna by first trimming it for a 1:1 match on 30 meters including a loop and strain relief to attach the extension.

When I was satisfied with my 30M EFHW, I then made the 40M extension, attached it to the 30M section with 2mm bullet banana connectors, then trimmed the antenna for a 1:1 match on 40M.

I spent the better part of 60 minutes trimming this antenna. I feel like patience really pays off because it’ll set up the antenna for good matches on all of the upper harmonics. Admittedly, I was a bit pressed for time that day, so I only tested this antenna in one configuration (an inverted vee shape) so hadn’t checked the SWR as a sloper or vertical.

My advice is to aim for a 1.3:1 or better match on 30M and 40M–that should be very doable if you wound your transformer correctly.

This was my first attempt at making in-line links, so I wouldn’t consider link my method as a “best practice”–rather, check out K7ULM’s guidance for making in-line links. Continue reading SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit! →

Greg discovers the joy of QRP in his first QRP SSB POTA activation

Many thanks to Greg (KJ6ER) who shares a post he originally published on Facebook regarding his first ever QRP SSB POTA activation. This post is just as much a break down of his field kit, so we’re also including it in our Field Radio Kit Gallery.

My First POTA QRP SSB Activation

by Greg (KJ6ER)

Wooo hooo! After 700 QRO SSB POTA activations in California over the past 2 years, I decided to try my first 10-watt QRP SSB activation from K-3473 in San Jose. To my pleasant surprise, it was very successful: 121 SSB QSOs in 4 bands (10, 12, 15 and 17M) across 5 countries including DX to Japan, Alaska and Argentina. I worked 34 U.S. states and 5 Canadian provinces. I operated a total of 4 hours, averaging a QRP QSO every 2 minutes. Lesson learned: Inspired by my QRP mentor Kevin Behn, QRP is not only as fun as QRO (when the bands are working) but it is simpler and faster to deploy. And I can wear the entire station on my back!

My QRP shack-in-a-pack is the ICOM IC-705 (in an ICOM backpack) with a 7M Spiderbeam fiberglass telescoping pole and my homebrew resonant halfwave monoband antennas. Quite frankly, a significant contributor to my success was the monoband resonant halfwave antenna: low angle of radiation and more gain than a typical quarterwave with radials. I modeled this after my homebrew POTA Dominator resonant halfwave antenna. If you’re interested in more detailed information about this antenna and components in my backpack, take a look at each photo with descriptions (below).

Starting on 10M, I was planning to work my way down the HF bands to 20M where I assumed would get me the most QSOs and help me officially activate.

Well … I never made it to 20M: by band, 24 QSOs on 10M, 13 QSOs on 12M, 32 QSOs on 15M and 52 QSOs on 17M = 121 QSOs! I will plan to do a 20 and 40M QRP activation soon, as well as 2M and 70cm since the IC-705 supports those bands, too.

Many thanks to all the hunters who helped me complete my first QRP activation! While I certainly did not experience any massive pile-ups like my typical QRO activations, the slower pace QRP activation made it very relaxing. I strongly recommend it! Feel free to let me know if you have any questions, I’d be happy to help  72 KJ6ER, San Jose

Field Kit Details

My complete QRP shack-in-a-pack!

The ICOM IC-705 running 10 watts off a 3Ah Bioenno battery. Just to the right of the pack in the field is my 7M Spiderbeam fiberglass telescoping pole supporting monoband resonant halfwave wire antennas for 10M, 12M and 15M. I also use the pole to operate on 17M and 20M as a sloper or inverted-V, and 40M as an inverted-V. I love how fast I can get operating with just a backpack and telescoping pole!

My first QRP SSB 10-watt activation resulted in 121 QSOs on 10-17M including DX to Japan, Alaska and Argentina.

I thought I would need 20M to activate but the uppers bands worked so well, I never got there. I completed my activation in 4 hours and averaged about 1 QRP QSO every 2 minutes. While I was not getting my usual 5-9 QRO signal reports, I was heard clearly on the low noise upper bands with my QRP SSB signal.

The 7M Spiderbeam fiberglass telescoping pole supports my monoband halfwave vertical wire antennas for 10M, 12M and 15M, as well as 17M and 20M when used as a sloper or inverted-V. I also use it as a center mast for my 40M inverted-V. Continue reading Greg discovers the joy of QRP in his first QRP SSB POTA activation →

(tr)USDx Ultralight Portable Kit

by Jim (KI7URL)

I like to take amateur radio with me wherever I go. In my backpack, I keep a Yaesu FT-60 (powered by 18650 batteries, but that is a different discussion). But I do not like to limit myself to VHF/UHF.

My wife, on the other hand, does not think my “go bag” should take up a significant portion of our suitcase when we travel. I did build a slimmed-down go kit with my Yaesu 891, but that was still north of 12 pounds (vetoed by Wife). Then, I made a go kit with my Yaesu 818, but that was still near the 10-pound zone (again, vetoed). I needed a slimmer package.

I turned to the likes of the QCX mini or other CW-only radios. The problem is that I still am far from proficient with my code, so relying only on CW was a bit more frustrating than I wanted it to be. The (tr)USDx, an open-source radio about the size of two stacked decks of cards, interested me in both price point and functionality. It has SSB, CW, and digital capabilities….on five different bands! Once it was in my hands, I had to build a kit around this new radio!

I want to keep my radio protected, so I started with a small dry box. On the inside, I printed a ‘redneck laminated’ (see also: packing taped) a quick setup guide for using the radio on digital modes if I ever have an in-field case of “the dumb.”

The radio is powered by a small RC battery. I chose this for size, weight, and availability (had it lying around from another project). When fully charged, it reads 12.6 volts. I added powerpole connectors to it because who does love powerpoles (be careful not to short the battery when adding power poles)? I have a small power adapter that goes from powerpoles to the 1.3mm connector so I can use my bench supply or other power sources without making another cable.

I have two antennas that I use (a K6ARK end fed and a QRP Guys No-Tune end fed with 26 gauge wire for 20m). But I like the QRP Guys one because I mostly do 20m and I think it was slightly lighter than the K6ARK antenna (don’t quote me on that though, I loaned the K6ARK one out and have not gotten it back). Plus, not having a tuner lightens my load as well!

Deployed for digital modes.

I have a retired smartphone in my kit that I use for some logging and some other ham-related apps, but mostly for FT8 using the FT8CN app. I also have WoAD on there and soon I hope I can get WinLink functionality with a small TNC as per this video by OH8STN. HF WinLink would be a good benefit with a lighter load than packing in a laptop or Raspberry Pi.

The kit weighs in at 2 pounds 6 ounces (just over a kilogram). This could be stripped down if I only did an SSB, Digital, or, gasp, a CW activation. But as it stands, the small form factor and low weight make the wife happy!

73,

VE6LK makes a quick trip to Montana o/a AI7LK – Day 2

2 Comments

by Vince (VE6LK)

As you read in day 1 of this story, I landed up in Montana opportunistically. The plan for day 2 was to say goodbye to our visiting family, then make our way north from Kalispell, MT via Eureka, MT and head for home. We’d stop on the way to visit with friends and, of course do one more POTA activation.

Operating position at K-4848. This spot is at the south end of Lower Stillwater Lake.

After departing Kalispell we arrived at Lower Stillwater Lake, part of K-4848, at around 11am MT.

There is one picnic table near a boat launch and it was vacant so I got to work quickly and set up. I had brought along a lightweight kit consisting of my VE6VID EFHW, Elecraft AX-1, the KX3, a battery, a key, a paper logbook and some extra bits like carabiners, a bit of masonry string and a small mast that I landed up not using. With my wife and doggo along for the ride, I didn’t want to take too much time to set up and operate, so the natural choice would have been the Elecraft AX1 antenna, but with conditions being as soft as they were a day earlier, the resonant wire antenna seemed the better choice for the extra 5 minutes it would take to set up.

This short video shows my full set-up:

I looped the feedpoint end around a nearby tree branch and unrolled the antenna and tossed it up in a branch just out of my reach – another low-slung wire antenna! The rest of the gear came out on the table and I used the tote box as a makeshift stand for my shortie camera tripod. Continue reading VE6LK makes a quick trip to Montana o/a AI7LK – Day 2 →

VE6LK makes a quick trip to Montana o/a AI7LK – Day 1

6 Comments

by Vince (VE6LK)

Luck is what happens when preparation meets opportunity.

In early August 2023 I was lucky to be able to activate parks in beautiful West Montana on such short notice.

As opportunity would have it, my brother Dan, AG7GM, and Sister-in-Law Val were at the tail end of visiting with us and wanted to do a drive on Glacier National Park’s Going-to-the-Sun Road as part of their return journey home. We had attempted this trip with them some years ago but were met with inclement weather and were turned around after landslides blocked the road. After an overnight stop in Kalispell for all of us, they would continue towards home and we would head back to ours.

The preparation involved plotting out which of the 9 parks I could tackle along the routes I would be travelling. I settled on K-0028, Glacier National Park and K-4848, Stillwater State Forest. But, still, my activations would need to be opportunistic in nature and involve a willing family allowing me to partake in one of my favourite activities.

Before you do this road trip, you need to understand that the Going-to-the-Sun Road is highly popular and the park restricts the number and type of vehicles that pass along it each day. You can find out more details about Going-to-the-Sun Road here. While their advance booking system granted me one vehicle pass, I needed two and was unsuccessful in the days before the actual trip to secure a second one. Luckily (there’s that word again) we arrived after 3pm when passes are not required at this time of year. I was absolutely stoked as I love driving on mountain roads!

An in-depth review of the Xiegu G106 QRP HF transceiver

16 Comments

Note that the following review first appeared in the May 2023 issue of TheSpectrum Monitor magazine.

Update: Also, please note that the G106 is on sale at Radioddity at time of posting. With our affiliate link pricing is only $264 US (see note at end of review). Please read this review prior to making a purchase decision!

An in-depth review of the Xiegu G106 QRP HF transceiver

by Thomas (K4SWL)

Last year––in May of 2022, that is––Xiegu announced a new compact field radio that would be added to their line of transceivers: the Xiegu G106.

Xiegu has really made a name for themselves over the past few years with several transceiver offerings, many of which have become very popular. Among these:

  • The Xiegu G90 is a 20-watt transceiver with an excellent built-in ATU. The G90 has become a very popular field radio over the past few years.
  • The Xiegu X5101 is a five-watt shack-in-a-box HF transceiver covering 160-6 meters. The X5105 has become a go-to QRP portable due to its fine built-in ATU and built-in rechargeable battery pack.
  • The Xiegu X6100 is much like the X5105, in that it’s also a shack-in-a-box QRP transceiver, but it leverages SDR technology to provide a beautiful color spectrum display and a host of features not found on its predecessors. Many have adopted the X6100 because its operating system is Linux-based and many enthusiasts have created their own X6100 interface that promised direct digital mode operation.

Because we’re seeing more products like these from Xiegu, the up-and-coming Xiegu G106 stirred interest.

Moreover, Xiegu has become a low-cost leader among HF transceiver manufacturers. In each of the reviews I’ve published about Xiegu radios, my summary statement is that each unit offers a lot of performance for the price. Xiegu transceivers don’t have the most robust receiver front-ends, and the audio is unrefined, but their rigs get the job done and have some serious “fun factor.”

So when I first learned about the new Xiegu G106, I was curious where it would fit into their product line.

Introducing the Xiegu G106

As I was capping off my summer in Canada back in August of 2022, Xiegu retailer Radioddity started shipping the G106. Radioddity had me on the list to send a loaner G106 for review, but  upon my return I found myself so busy that I didn’t immediately request it.

I did watch, however, K8MRD’s initial and updated review of the G106 on YouTube. While it was less than stellar––understatement alert––more relevant to me was that Mike shipped his second evaluation unit to me on behalf of Radioddity.

I connected that G106 to a dummy load, checked the transmitted signal on my SDRplay RSPdx spectrum display, and it simply didn’t look very clean. In fact, it looked worse than it did when Mike checked it only a couple of weeks prior.

I shared my results with Radioddity and told them I didn’t feel comfortable putting the G106 on the air; they asked that the unit be returned and checked out.

Fast-forward to January 2023, when I was once again contacted by Radioddity to see if I would like to field test an updated G106? I answered that I was happy to do so, because I was curious whether the G106 experience had improved.

In the spirit of full disclosure, keep in mind that Radioddity is a Xiegu retailer/distributor––the company is not the manufacturer, nor is it owned by Xiegu. They sent this G106 to me on an extended loan for an honest evaluation.

So where does the G106 fit into the Xiegu product line?  It’s being marketed as a low-cost, entry level, multi-mode QRP HF transceiver that leverages 16-bit CODEC sampling to provide the user with a lot of radio for the price. It’s basic, and meant to be so, in that  it’s only a transceiver; there is no built-in ATU or battery. The G106 is marketed as a bare-bones portable HF transceiver.

I feel like it hits this mark.

The G106 doesn’t have a lot of features or controls one might expect in other Xiegu radios, but it has more features than any other modern HF radio I know of in its price class (see features list below). Indeed, I can’t think of any other 80-10 meter general coverage QRP transceiver that retails for $320 or less. The G106 has this market niche to itself for the moment.

Overview

When I first received the G106, I was a little surprised:  it was even more compact than I had imagined.

The sides of the G106 are rounded and the chassis extends beyond the encoder and front controls of the radio, thus the interior is quite well protected in the event the radio is dropped. This is one of the few QRP field radios on the market that doesn’t need an aftermarket cage. I’ve been transporting the G106 in an old hard shell headphone case a friend gave me. The case isn’t large, but it easily holds the G106 and a power cord with a bit of room to spare.

 

The G106 sports a small monochrome backlit display that’s very easy to read in the shack or in the field with full sunlight.

Besides the weighted encoder (which has soft detents), the volume control, and microphone port, there are also four multi-function buttons located under the small display on the front panel. On top of the radio, there is a power/backlight button, mode/pre-amp button, and two band buttons that also can be pressed and held to change the frequency cursor position. The internal speaker is also mounted on the bottom of the top cover, just behind the top panel buttons.

On the back of the G106, you’ll find a BNC antenna port, ground/earth lug, key port, COM port, 8 pin ACC port, and a DC input port.

The most conspicuous omission is a headphone or external speaker port. I would have expected this in a QRP field radio because operators often prefer using headphones in the field rather than a speaker. I know that some G106 owners have built their own RJ9 audio plug to port out the audio to headphones. There is a headphone port on the supplied speaker mic, but CW-only operators might prefer a more direct way to connect earphones in order to keep the bulk of their field kit to a minimum.

What is surprising is that the G106 has a very basic spectrum display that is actually quite useful!

Ergonomics

The ergonomics of the G106 are overall pretty good…but a bit quirky. To be honest, giving the user access to numerous functions and features on a radio this small is always going to affect ergonomics; there’s only so much control-surface real estate.

Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Many thanks to Jonathan (KM4CFT) who shares the following guest field report and video:

Chatfield State Park (K-1212)

January 20, 2022

by Jonathan Kayne (KM4CFT)

The honorable Yaesu FT-817/818. You all know it and love it. I had been wanting to get myself one for a while but after just buying myself a shiny new ICOM IC-705, I had been planning on getting myself an 818 in the spring to play around with. December came and I find out that Yaesu was going to discontinue the 818, so I went and bit the bullet and bought one from Ham Radio Outlet.

I had been getting into CW for portable operations lately after wanting to learn CW for a while and my friend Zach Thompson (KM4BLG) had pushed me to learn it. I learned it over the course of two months through an app called “Morse Machine” and listening to Thomas’s YouTube videos while working so as to get used to the exchanges and pick up words. Then I activated and all the rest is history! (If you want to see my 3rd time activating see this video here.)

Why is this important? Because the FT-818ND does not have a narrow 500 Hz filter for CW operation by default, and since I consider myself to be still a newbie I wanted to install a Collins Filter before I take my new 818 into the field. Since these filters are hard to obtain, I went with the build your own route. The method I used has been outlined in this blog and I have made a video of it here.

Now that I had my radio all ready to go with a filter, side rails, and Windcamp Battery, I wanted to get it in the field as soon as possible. Unfortunately due to a snow storm, the temperature in the Denver area was quite cold.

I can handle myself pretty well in the cold if I put on enough layers, but my fingers are another story. I have found that I cannot write properly unless my fingertips are exposed. The solution: do the activation in the car! Continue reading Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation! →

QRP by Lantern Light: A CW/SSB sunset POTA activation at Lake James State Park

3 Comments

The one thing about doing POTA activations in the winter is being aware of just how short the days are. It seems like, lately, I’ve had a number of activations that have spilled over well beyond sunset.

With POTA, running out of sunlight really isn’t a big deal. As long as I have a headlamp (I always do) and/or a lantern, I can continue operating as long as the park is still open to guests.

With SOTA, running out of sunlight can develop into a serious situation, especially if you’ve bushwhacked to a summit in unfamiliar territory. Even with a headlamp, it can be difficult finding your way back to an established trail.  I’ve never scheduled a SOTA activation that pushed sunset unless I’m comfortable with the path to the summit.

If I’m being honest, I think a part of me actually enjoys doing POTA activations after sunset. It feels a lot like camping.

On Sunday, December 4, 2022, I was on the road once again and could not help but squeeze in a POTA activation at Lake James State Park.

It was late afternoon and I knew I’d be pushing sunset, but I had my little LED lantern just in case I ran out of sunlight (hint: I did!) and I was ready to play some radio: both CW and SSB!

Lake James State Park (K-2739)

It was a grey, chilly day and there were no other cars in the parking lot at the Catawba River Access. I had the whole park to myself until closing time at 7:00PM.

I chose a picnic table by the lake, putting some distance between me and the visitor’s center which has been known to spew radio interference (QRM) in the past.

I brought along my Elecraft KX3 for this activation.

The KX3 is one of my top field portable radios, but I rarely take it to the field these days for a couple reasons:

  1. It’s my main shack radio and is hooked up to my KXPA100 amplifier 100% of the time (although I rarely run enough power that the amplifier engages). I do much of my park/summit hunting from home with the KX3.
  2. Since I purchased my KX2 in 2016, I tend to take it to the field instead since it’s *that* much more portable. It’s like a smaller version of the KX3 with nearly the performance and only lacking 160 and 6 meters.

But I do love my KX3. It’s a benchmark radio–and one of the best field transceivers on the market.  You will see a few field reports with it each year since I try to give all of my radios a regular dose of fresh air!

Setting up

After recording the intro to my activation video (which I tried to do before the sun actually set), I decided to film the antenna deployment as well.

I debated which antenna to use at the site. I decided upon the super easy-to-deploy 28.5′ “no transformer” random wire antenna by Tufteln (see link in the Gear section below). I first demoed this super simple antenna on Mount Mitchell during a SOTA activation. It’s basically two lengths of 28.5 foot 26 AWG wire connected to a BNC connector on a small 3D printed mount which provides strain relief.

This antenna is basically my super simple speaker wire antenna, just in a more compact form factor.  Since there’s no transformer, the antenna relies on an ATU to do all of the heavy work of sorting out impedance matches.
