Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation!

8 Comments

I’m very fortunate in that over the past few years I’ve accumulated a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

I’ve written formal reviews about most of the field radios in my collection over the years. In those reviews, I try to take a wide angle view of a radio–I try to see how it might appeal to a number of types of operators: field operators, DXers, summit activators, contesters, rag-chewers, casual operators, SWLs, travelers, outdoor adventurers, mobile operators, etc. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

On that note, I thought it might be fun to take a radio out for a field activation and spend a bit of time explaining why I enjoy using it and why it’s a part of my permanent field radio collection. Instead of taking that wide-angle view of a radio like I do in magazine reviews, I share my own personal thoughts based on long-term experience.

Each new video in the Getting To Know You series will highlight one of the field radios from my field radio collection.  I’ll spend time in each video explaining what I personally appreciate about each radio, then we’ll do a park or summit activation with the radio.

I’ll release these every few weeks or so–when the notion strikes me.  They will not be on a regular schedule, but I hope to include each of my radios in this series over the the next year.

The Ten-Tec Argonaut V

The third radio in the Getting To Know You series is my Ten-Tec Argonaut V (Model 516).

I’ve always been a big fan of Ten-Tec products because I love their focus on quality, high-performance receivers, and benchmark audio fidelity.

Ten-Tec has produced some impressive radios over the years and was a trail-blazer in the world of QRP with their Power Mites and original analog Argonaut series (check out these and more T-T radios here).

When Ten-Tec manufacturing was located in Sevierville, Tennessee, I knew many of the employees of the company and even did Alpha and Beta testing for their QRP radios like the Patriot, Rebel, and Argonaut VI.

I love the ergonomics and simple front panel design of the Argo V.

I purchased my Argonaut V used in 2021 when I saw it for sale on QTH.com. The price was right and, frankly, I wanted a Ten-Tec radio back in my life.

In the activation video (below) I’ll speak to all of the reasons I love the Argonaut V, why I think it’s so unique, and why I’ve no intention of ever selling it. Then, we’ll perform a POTA activation with it.

Keep in mind that my perspective will primarily focus on HF CW operating–I don’t actually own a microphone for the Argonaut V, but I do plan to at some point.

Lake James State Park (K-2739)

On Sunday, August 13, 2023, I made a detour to Lake James State Park en route to visit my parents in Hickory, NC. As I’ve mentioned many times before, Lake James is one of the easiest parks I can hit in my travels and it’s open every day of the week–in the summer, it’s also open quite late which is a bonus.

The only negative with evening activations at Lake James is fighting the mozzies–they can be persistent!

I picked out a picnic table close to the car and pulled the Argonaut V from my Husky latching box.

I then immediately deployed my MW0SAW 40 meter End-Fed Half-Wave antenna. Since the Argonaut V doesn’t have an internal ATU, the EFHW would give me the flexibility to operate on 40, 20, 15, and 10 meters natively.

Of course, it was in the early evening, so I only intended to hop on 40 meters, but I had the option to move up the band if needed.

After deploying my antenna, I recorded the “Getting To Know You” portion of the activation video–I’d encourage you to check that out below!

Time to hop on the air! Continue reading Getting To Know You Series: The Ten-Tec Argonaut V (Model 516) – My thoughts, notes, and a POTA activation! →

Best QRP field transceivers for operators who are blind/visually-impaired?

8 Comments

I recently received the following inquiry from Vic (K7HSS) who shared that he is blind and seeking a field-portable transceiver that is user-friendly to those who are visually impaired. 

Vic notes:

I’ve actually owned the KX2 before, but it was now sold, because I realize that I was sitting on a lot of money, and I wasn’t doing that much portable operations at the time.

The KX line is ideal because it has CW read outs. Having said that, I will be able to make do if a radio somehow stops or notifies me at band edges. From there, I could put some sort of markers on the knob, so that I could roughly gage where I am base on how many spins I’ve given the knob. I’m not very sure how the single band radios like the QCX mini operates. Does it stop once you reach the band edge?

Anyways, those are some thoughts that I have. Also, I’ve been following your Youtube channel and blog for quite a while and is definitely a fan.

I hope you will have a lovely day.

Best and 73,

Vic (K7HSS)

Thank you for the kind words, Vic. 

I’m not visually-impaired so feel like I can’t really comment here, but I do know of at least two other hams who are completely blind and use the Elecraft KX3. From what I gather, it is loved for the CW read outs (as you mentioned) and for there being a dedicated tactile button and/or knob for most of the important functions and features one would use in the field.  

Vic would welcome your comments especially if you are visually-impaired or if you can provide insight about radios with features (like band edge notification) that make it more accessible.  Click here to comment!

QRPer Notes: 23cm on the IC-705, New Color Counterpoises, and Rekindling the NJQRP Club

4 Comments

Because I receive so many tips from readers here on QRPer, I wanted way to share them in a concise newsletter format.  To that end, welcome to QRPer Notes, a collection of links to interesting stories and tips making waves in the world of radio!

1296 on the Icom IC-705

Many thanks to Alan who shares this video of VK3FS operating his Icom IC-705 on the 23cm band.

Video description:

If you enjoy SOTA, parks, microwave or radio in the great outdoors, then Icom IC-705 is the radio for you. Having received many accolades, and a long list of positives, some might say there’s one thing missing on the IC-705 and that’s the 23cm band.

The good news – is it’s a relatively easy fix with the help of a 1296 MHz transverter from SG Labs.

Chameleon adds color counterpoise kits to catalog

Many thanks to Don (W7SSB) who notes that Chameleon antennas has added color counterpoises to their product offerings.

Efforts to Rekindle NJQRP Club

Many thanks to Dennis (K2DCD) who shares the following message sent originally by Larry (W2LJ):

Once again, I’ve been giving thought to attempting to pump new life back into the New Jersey QRP Club. For many, many years it was considered to be one of the top QRP organizations in the country. It ranked right up there with the NorCal QRP Club, the Colorado QRP Club, the New England QRP Club and others.

In the early 2000’s, due to the efforts of George N2APB and Joe N2CX and a host of others, the NJQRP Club reached its azimuth when it sponsored Atlanticon, the QRP confab of the Mid-Atlantic Coast. It was held in Baltimore and each year I was dying to go. But my two kids weren’t even really toddlers yet, and with Marianne and I both working full time, it was an impossibility.

Soon after Atlanticon ceased, it seemed the club started to wither away. Stalwarts became Silent Keys, others moved away and NJQRP started to become a shadow of its former self. There were a few times I met with other members at the food court of one of the malls near Princeton. There were also a few outdoor gatherings at the park in Grover’s Mill – the infamous landing spot of the Martians in Orson Well’s “War of the Worlds”. And then finally there was nothing.

So where does that leave us? The website was moved to its present URL location in 2016. As far as I can tell, there have been no updates. And in all honesty, except for the Skeeter Hunt, there hasn’t been much activity to update the webpage with. Whatever the members have been up to individually, there’s been no real effective means of communication between them.

George N2APB has moved to Tennessee and N2CX is a Silent Key. There’s no roster, so there’s really no way to tell who was a member and who was not, and what members if any have either moved out of the area or have become Silent Keys. And since the last iteration of NJQRP, there just may be a whole new generation of New Jersey QRP’ers anxious to meet their like minded brethren in the state.

So we start with a new beginning. I started a Facebook page. As of right now, it’s a public group and I think you can just join. I’ve also started a Groups.io group now that Yahoo groups are defunct. This group will be an e-mail reflector and our main way of keeping in touch with each other. If you’d like to join that, you’ll have to send me an e-mail ([email protected]) and I’ll send you an invitation to join.

Granted, it’s not much of a start, but it is a beginning. Hopefully, as the word spreads and QRPers in New Jersey and the surrounding area become interested, maybe we can start holding meetings, if we can find a location that is convenient for all.

I’d like to stress that while the New Jersey QRP Club will primarily serve local QRPers as far as any future live in person events go, there are no residency requirements. All are welcome and if we do meet in person, we can always incorporate a Zoom component as other clubs I belong to have been doing to include those who can’t attend in person for whatever reason.

It’s not my job to run the organization, that will be up to the members. I’m just going to try and re-launch it. So stay tuned – maybe we can light this candle and get this puppy off the ground!

Survey #3 Results: What QRP HF transceiver would you or do you choose for air travel?

17 Comments

This past week, I posted the third of several surveys on QRPer.com, this time asking:

“What QRP HF transceiver would you or do you choose for air travel?”

I turned off the survey at 6:30 EDT today, with a total of 475 responses.

Survey Results

Here’s a pie chart showing the top 18 results in the survey. To see detail, you will need to click on the image below (or click this link) to enlarge it in a new window:

The top choice was the Elecraft KX2 which accounted for 22.9% of the votes.

It’s funny: I had assumed the Icom IC-705 might take first place in this survey. Then I realized that I own both the KX2 and IC-705 and, this summer, I chose the KX2 each time I traveled. Indeed, I can’t think of a time in recent memory that I didn’t take the KX2 with me during travels.

The reason I picked the KX2 each time is because it’s such a comprehensive HF radio with a superb built-in ATU and battery pack. There’s no field situation I can throw at it that it can’t handle. In fact, if a site doesn’t allow any antennas on the ground, I can even pair it with my AX1 or AX2 tabletop antennas.

I see why so many of you picked it as your first choice.

Your second choice was the Icom IC-705 which accounted for 14.3% of the votes.

The IC-705 has one very cool feature for travel: you can charge it with a common Micro USB charger!

No need to take a separate power supply, battery pack, or custom charger. Simply bring a Micro USB cable and plug it into the hotel USB charger, your phone’s charger, or even a Lithium power pack. If you’re happy with 5 watts of output power, you really need no other battery, power supply, or charger.

Of course, the IC-705 is compact, sports the entire HF band, VHF, and UHF and is multimode. It can also receive FM and AM broadcasts along with weather radio, and the AIR band.

You can even do D-Star natively and allow the GPS in the IC-705 to find the closest repeaters and load them to memory.

The IC-705 is a very savvy travel transceiver!

Your third choice was the Yaesu FT-817/818 which accounted for 9.9% of the votes.

At first, I was a little surprised the FT-817/818 would gather more votes than, say, the Elecraft KX3, but then again it’s actually a very compact radio. I remember when I used to travel Europe for a living, I would tuck my FT-817 into my carry-on and I hardly noticed it was there.

It also ships with a NiMH battery pack, and you can also buy a much longer-life and faster-charging Li-Ion pack.

The FT-817/818 is a rugged radio. You don’t have to worry about it being harmed in a pack and it lays pretty flat as well so it’s easy to protect and pad among your clothes.

The Elecraft KX3 took forth place with 8.6% of the votes.

The KX3 is one of the highest-performance field radios ever made and it is incredibly portable.

I added the Side KX panels to my KX3 many years ago. With those installed and using the Lexan cover, it’s a very rugged radio. Simply toss it on your flight bag and you’re good to go!

The KX3 is also a very efficient radio, so you could easily power it with, say, a $25 Talentcell USB battery pack–one that TSA wouldn’t blink at.

I’ve traveled pretty extensively with my KX3 so I see why it ranks so high on the list. Like its newer sibling, the KX2, it has an amazing internal ATU. You can also load the KX3 with AA cells for short on-the-air sessions or longer listening sessions.

Fifth on this list of travel radios is the Xiegu X6100 which accounted for 6.1% of the votes.

No doubt, what makes the X6100 so appealing is that, like the KX2, it’s a proper shack-in-a-box. Indeed, I would also add the X5105 to this same list.

The X6100 contains a high-capacity rechargeable internal battery pack and an excellent ATU. It’s an all-in-one radio solution that’s actually quite rugged and could easily handle the bumps and jolts of air travel.

Notable mention…

There was another winner in this survey. It wasn’t any one model, but rather a whole class of HF transceivers: super compact portable transceivers. If lumped together as a category, these would have placed in the top five.

I’m talking about radios like the: Mountain Topper series, QCX-Mini, QMX, QDX, SW-3B, (tr)uSDX, TR-25, TR-35, and similar. These radios are so incredibly tiny that they can be packed away in a very compact pouch.

Indeed, I have a complete dedicated POTA/SOTA station built around my Venus SW-3B (see photo above). It’s all contained in a small BROG headrest pouch that I could easily toss in a travel bag.

These pint-sized radios aren’t general coverage radios like the top 5 listed above, and many are CW-only. Still: if your goal is to hit the field a bit during your vacation, they’re incredibly effective.

This radio class also represents some of the most efficient and affordable transceivers on the market.

Survey 3: What QRP HF transceiver would you choose for air travel?

21 Comments

Many of us are traveling this summer and with pandemic concerns lessening, we are taking to the air and going much further afield!

This summer, I’ve gotten a number of inquiries from readers asking about the “best” HF QRP radios for air travel.

While I have suggestions, in truth, these days the radio selection often comes down to availability. It might be difficult to order and receive your first choice radio prior to your travels unless you scope out the used market or are simply looking ahead to travels next year.

With air travel in mind, of course, transceiver size and weight become important factors especially if, like me, you’re a one-bag traveler.

In addition, being able to easily power the radio without a large/heavy external battery/power supply is also important.

This is why QRP radios are so ideal for air travel; they’re so much easier to stash in luggage compared with their 100 watt siblings.

Survey #3

The first and second surveys we posted were so much fun and insightful! As I mentioned in May, I’ve a number of surveys in store this year.

As with our previous, surveys, this one also also focuses specifically on HF QRP transceivers.

If you would like to participate, please use the Google Form below. If you don’t see the radio you would choose in this list, feel free to add it in the “Other” selection, but again, please do not list 100 watt radios in this particular survey that focuses on QRP HF transceivers.

While the survey form doesn’t allow for comments, this QRPer post does! Please consider sharing your thoughts about the radio you chose in the survey–this is a brilliant way to elaborate on your entire travel set-up. Being a radio, pack, and travel geek? I love this stuff!

Thank you!

The Elecraft KX2

The first radio in the Getting To Know You series is my Elecraft KX2.

Without a doubt, I’ve put more time in with the Elecraft KX2 than any other radio I’ve ever owned. As a field radio op, it’s one of my all-time favorite transceivers.

I originally purchased and reviewed the KX2 in 2016 (click here to read my review).

In the activation video (below) I’ll tell you about how I acquired my KX2, why I think it’s one of the best portable HF field radios ever made, what makes it so unique, and why I turn to it more than any other radio I own. Then, we’ll perform a POTA activation.

Tuttle Educational State Forest (K-4861)

On Friday, June 23, 2023, I pulled into Tuttle Educational State Forest knowing it could rain on me at any point. We’d just come out of nearly a solid week of rain (after a very long dry spell). I had packed my ENO rain fly in the car, but my hope was that the Tuttle picnic shelter would be unoccupied.

POTA & SOTA at Monte Sano State Park in Huntsville, Alabama!

9 Comments

I had some big POTA plans for Alabama this summer.

After returning home from Hamvention, I had about three days to prepare my truck, our small travel trailer/caravan, and pack for one week of camping in Huntsville, Alabama.

We had a great excuse for hanging around Huntsville: my daughter was attending Advanced Space Academy (Space Camp) at the U.S. Space and Rocket Center.

The drive to Huntsville is about five hours and we decided that it would fun to go camping with not a whole lot to do for a week. Proper relaxation!

I looked at the POTA map in advance and plotted out at least four or five parks I could activate without driving too far. I planned to fit in activations on Sunday, Tuesday, and Wednesday. Thursday, we planned to spend the full day at the Space and Rocket Center and Friday was my daughter’s graduation.

My truck, though, had other plans!

About half way on our journey to Huntsville, my 1997 Dodge Ram 2500 started to have issues. Without going into too much detail here, there seemed to be a problem with the accelerator.

We drove to Huntsville on the Saturday of Memorial Day Weekend, so not an ideal time to have mechanical issues. I limped to truck to Alabama and waited for a diesel shop in Huntsville to open on Tuesday morning.

In the meantime, I was able to hunt POTA and SOTA stations from our campsite which overlooked the Space Camp model rocket launching station. No kidding: we probably witnessed some 300 model rocket launches during the day that week and it was an absolute blast (pun intended).

I never got tired of seeing a full scale Saturn V model above the tree line on our evening walks!

Fortunately, the diesel shop was able to sort out the issue and fix it in one day–I was super pleased with that. However, that only left Wednesday to play POTA–we’d already plotted out a visit to Monte Sano State Park. That was fine by me because, turns out, almost the entirety of Monte Sano State Park is also within a SOTA activation zone! A SOTA/POTA two-fer!

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

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.

Activating (sort of) Lake Thunderbird (K-2792) with a homebrew transmitter

Sam Duwe WN5C

When I dove into radio a couple years ago a few sub-hobbies caught my attention: QRP, portable ops, CW, and homebrew. Of course, these all fit nicely together, but in my mind there was a huge leap between soldering an unun and a building a radio. But why not try? What’s the worst that could happen by melting solder and then sitting at a picnic table? This is how I built a simple transmitter and kind of activated a park.

The Michigan Mighty Mite

Nearly everyone has heard about the Michigan Mighty Mite (MMM), a QRPp transmitter popularized by the Solder Smoke blog. There are countless YouTube videos and posts across the internet. It’s very simple: a single transistor, a variable cap, a coil, a crystal and some resistors and a cap. Supposedly one can get up to half a watt of output (I couldn’t). But with a small purchase from Mouser one can oscillate. That seemed pretty cool.

I hadn’t touched an iron until I started playing radio. But I’ve been drawn to homebrew projects. I built a regenerative receiver last year which was very rewarding. I’ve also put together kits (a QCX mini and a TR-35). But my dream has always been to construct a transmitter/receiver combo, or a transceiver. I thought a good place to start was the MMM.

I built the transmitter based on the common schematic for the 40-meter band. The MMM is crystal controlled but I opted to solder in a socket and buy a handful of crystals, so I have the luxury of operating on 7056, 7040, and 7030 kHz. I made a few other improvements, too. The first was to build a low pass filter to attenuate harmonics. Second, although I haven’t finished it yet, the switch on the right will be to choose between multiple crystals. And third, I added a BNC jack to connect a receiver, with a transmit switch. When not in use the transmitter will dump into a dummy load. This receiver switching idea was lifted from the design of the MMM that QRP Guys produces.

When I tested the transmitter at home the best I could get with my charged Bioenno 3 Ah battery was about 300 mW output. The filter is reducing things somewhat, but maybe I need to look into a different transistor or rewind the coil. But I was able to get a 339 signal report from Illinois (no sked) in the midst of distance lightning crashes, so I had a little confidence going forwards. School is out for me this summer, so I decided to head to the park. Continue reading Guest Post: Lake Thunderbird (K-2792) with a homebrew transmitter! →
