Survey #1 Results: What QRP transceiver do you turn to the most in the field?

This past weekend, I posted the first of several surveys on QRPer.com asking:

What QRP radio do you tend to use the most in the field?

The responses started flowing in immediately and within the first day we had already accumulated over 400 votes.

I turned off the survey this morning at 5:00 EDT with a total of 696 responses.

Survey Results

Here’s a pie chart showing the top 26 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 received 131 votes. I’ll admit, this was my top choice, too.

The KX2 is the most compact, full-featured radio currently on the market. I know of no other radio that weighs less and is smaller in size that also sports options for an internal battery and internal ATU. It’s also one of only about five radio models on the market that has a built-in microphone.

The KX2 is one of the pricier QRP transceivers on the market, so in that sense, it did surprise me that it was number 1.

The Yaesu FT-817 and FT-818 series transceivers took second place with 105 votes.

Since this radio enjoyed one of the longest production runs in the history of amateur radio–and the price floated around $650 US new–we shouldn’t be surprised. It has so many good things going for it; click here if you want a deep dive into why I think the 817/818 is a fantastic field radio.

The Icom IC-705 took third place with 101 votes.

The IC-705 is an incredibly versatile radio as well and it packs some serious performance! It’s also one of the priciest QRP radio on the market at around $1,400 US. Click here to read my full review of the IC-705.

These are only the top three radios–check out the full results below to see how the top ten ranked among a total of 48 entrants.

Survey 1: What QRP HF transceiver do you turn to the most in the field?

Last week, Phil shared results from a survey he conducted on Facebook regarding the most popular radios used for POTA. The survey was informal and, of course, only open to those in the POTA Facebook community.

The survey confirmed my suspicions that both the Yaesu FT-891 and Xiegu G90 were among the top radios used by POTA activators. Heck…I hardly know a POTA op that doesn’t have one of these two rigs–!

The survey also made me realize that I live in the world of QRP and often forget that the vast majority of ham radio operators do not, necessarily.

QRP Radio Survey Series

I thought it might be fun to publish a series of surveys over the course of the next few weeks that specifically focus on QRP transceivers.  Each survey will contain only one question.

These will all be informal surveys, but I’d like to have a fairly specific question in mind with each and would ask that you think about that question and answer it as honestly as you can. Many of these are subjective, so this isn’t always an easy task.

This first question, though? It’s easier to base on fact…

What QRP radio do you use the most in the field?

At the end of the day, our “favorite” radio might not be the one we actually use the most in the field.

In this first survey, please select the QRP radio you use most often in the field

Notes:

  • If you see a glaring omission in this list–a popular, mass-produced QRP radio I’ve overlooked–please comment and I’ll add it to the list.  Otherwise, simply select the “Other” choice and provide the manufacturer and model.
  • This list is pretty comprehensive, but I didn’t include some of the more obscure models, nor did I include vintage or Japanese Novice models simply because I see so few people using them as daily drivers in the field.
  • For this survey, I included radios with a maximum output power of roughly 20 watts.
  • The survey form has no place for comments, so if you’d like to tell us about your selection (even if it’s your only QRP radio), feel free to leave a comment on this post!

Thank you!

Survey 1:

The New Penntek TR-45L: A Video Tour/Overview, then a full POTA activation!

Yesterday, John (WA3RNC) opened orders for his long-awaited Penntek TR-45L 5 band, CW-only, QRP transceiver.

As I mentioned yesterday, I’ve had the pleasure of helping John beta test this radio for the past month. In that time, I’ve gotten to know the radio from the inside out and have even taken it on a few POTA activations. In fact, with John’s permission, I just posted my first TR-45L activation video for Patreon supporters yesterday. The radio was using an early firmware version in that video.

TR-45L Video Tour and Overview

Yesterday, after an early morning appointment, my schedule opened up; a rarity in my world.

I then got the idea to take the TR-45L out to a park, do a full video overview of its features, then put it on the air in a POTA activation.

Hazel loved this idea too.

So I packed the TR-45L, a log book, my throw line, and two 28′ lengths of wire. Hazel jumped in the car before I could invite her.

I’ve used a wide variety of antennas on the TR-45L over the past weeks, but I hadn’t yet performed a park activation only using two lengths of wire and relying on the TR-45L’s optional Z-Match manual antenna tuner. This would make for a great real-life test!

Quick note about video timeline

Side note for those of you who follow my field reports and activation videos

I pushed this video to the front of the line since the TR-45L just hit the market. I wanted to give potential buyers an opportunity to see and hear this radio in real world conditions thinking it might help them with their purchase decision.

I’m currently about 7 weeks behind publishing my activation videos. Much of this has to do with my travel schedule, free time to write up the reports, and availability of bandwidth to do the video uploads (I’ve mentioned that the Internet service at the QTH is almost dial-up speed).

I was able to publish this video within one day using a new (limited bandwidth) 4G mobile hotspot.  Patreon supporters have made it possible for me to subscribe to this hotspot service and I am most grateful. Thank you!

So that I can publish this report quickly (this AM), I’m not going to produce a long-format article like I typically do. Instead, this is one of those rare times when the video will have much more information about the radio and the activation than my report.  I’ve linked to and embedded the video below.

Now back to the activation…

Choosing a Field Radio: How to find the perfect transceiver for your outdoor radio activities!

The following article was originally published in the June 2022 issue of The Spectrum Monitor Magazine:


Choosing a Field Radio

by Thomas (K4SWL)

At least ninety percent of all of my radio operations happen in the field. Whether I’m in a park, on a summit activation, or I’m out camping, I’ve always thoroughly enjoyed “playing radio” outdoors. In fact, it was the joy of field radio––and the accompanying challenge of low-power operations––which launched my labor of love in the world of ham radio.

I’ve been running QRPer.com now for fourteen years, and during that time, the questions I’m asked most deal with selecting a field radio. Turns out, it’s an incredibly difficult question to answer, and we’ll touch on why that is before we dive into the reasons one radio might hold appeal over another for you.

Instead of offering up a list of field radios on the market, and reviewing each one—and, to be fair, there are so many these days—I’ll share with you a series of questions you might ask yourself before making a radio purchase, and follow up with a few bits of advice based on my own experience.These deceptively simple questions will help hone your decision-making. Finally, I’ll note a few of my favorite general coverage field radios and share what I love about each.

But, first…

Spoiler alert: It’s all about the operator, less about the specs

When searching for a new radio, we hams tend to take deep dives into feature and specification comparisons between various models of radios. We’ll reference Rob Sherwood’s superb receiver test data table, we’ll pour over user reviews, and we’ll download full radio manuals before we choose.

While this is valuable information—especially since radios can be quite a costly “investment”—I would argue that this process shouldn’t be your first step.

I’ve found that enjoyment of any particular radio—whether field radio or not—has everything to do with the operator and less to do with the radio’s actual performance.

A realistic assessment of yourself

The first step in choosing a field radio is to ask yourself a few questions, and answer them as honestly as you can. Here are some basic questions to get you started in your search of a field radio:

Question 1:  Where do I plan to operate?

If you plan to operate mostly at the QTH or indoors with only the occasional foray outdoors, you may want a field-capable radio that best suits you indoors—one with robust audio, a larger encoder, a larger display, and more front panel real estate.

On the other hand, if you plan to take your radio on backpacking adventures, then portability, battery efficiency and durability are king

Of course, most of us may be somewhere in between, having park activations or camping trips in mind, but overall size may be less important as we may be driving or taking only a short walk to the activation site. When your shack is a picnic table not too far from a parking lot or even an RV, you have a lot more options than when you have to hike up a mountain with your radio gear in tow.

Question 2:  What modes will I operate the most?

Are you a single mode operator? If your intention is to only use digital modes, then you’ll want a radio designed with easy digital mode operation in mind.

If you plan to focus on single sideband, power output may be more important and features like voice-memory keying.

If you plan to primarily operate CW, then the radio world is your oyster because it even opens the door to numerous inexpensive CW-only field radios.

If you plan to primarily operate CW,  I would strongly suggest going low power or QRP. I’ve often heard that 5 watts CW is roughly equivalent to 80 watts single sideband. I tend to agree with this. CW field operators hardly need more than 5 watts, in my experience.

And if, like most of us, you plan to operate a variety of modes, then you’ll want a radio that is multi-mode. Continue reading Choosing a Field Radio: How to find the perfect transceiver for your outdoor radio activities!

Which to choose? The Venus SW-3B or the Penntek TR-35?

Many thanks to Pat (N0HR) who shared following question in a comment:

Thomas

I simply love your videos – both your impressions of the gear and the activations themselves. Great stuff.

I’m curious – now that you’ve played with both the SW-3B and the Penntek TR-35, which is the favorite? Seems like they’re both roughly in the same price range.

Thanks for your fantastic channel and website

73,
Pat N0HR

Thank you for the kind words, Pat, and great question! Several people have asked me variations of this very question recently.

I like both radios, so I’ll frame this in a way that might help others make a purchase decision.

Spoiler alert: You really can’t go wrong with either radio and I feel it’s more a question of operator preferences. Continue reading Which to choose? The Venus SW-3B or the Penntek TR-35?

The new Mountain Topper MTR-4B V2 by LnR Precision

The venerable Mountain Topper MTR-3B

I’ve just noticed that LnR Precision has announced their new Mountain Topper MTR-4B V2.

They’ve released a few details with the promise of photos soon. Looks like the MTR-4B will of course sport four bands (80, 40, 30, and 20 meters) but adds two valuable tools its predecessors lacked: an SWR and RF power meter.

A full 5 watts output power is attained with a 12V supply, but the voltage operating range is 5.5 to 13volts.  The MTR-3B’s (photo above) has an upper operating range of 12V.

I look forward to checking out the MTR-4B and we’ll post photos as soon as they are available.

Here are the details from the LnR Precision Website:

Another very active table at the Dayton Hamvention and Four Days in May is that of Hendricks QRP Kits.

Doug Hendricks (pictured right) and his team produce some amazing, affordable QRP kits that fill many a niche in the shack. Below, I have photos of a small selection of their offerings at the Hamvention.  Note that all of these kits are available on the Hendricks QRP Kits website.

Many of Hendrick’s kits are suitable for beginners. If you’re in doubt about your kit building skills, simply contact the folks at Hendricks and they’ll help guide you to the right kit.

The NUE-PSK Digital Modem

QRPers have long been fans of PSK. And why wouldn’t they? The mode is efficient and uses DSP technology to help discover low bandwidth digital signals.  What that means for the QRPer is: 1 watt + PSK = DX   Very effective use of the juice!

Thing is, PSK has traditionally required the QRPer to bring along some sort of computer and a handful of wires and cables to take PSK to the field.

The American QRP Club has made this easier with the introduction of their portable digital modem–the NUE-PSK. This modem, like other AmQRP products is a kit and requires some experience with surface mount kits.

Here’s the AmQRP description of their modem:

The NUE-PSK is a small 7″ x 4″ x 1″ standalone, battery-operated digital modem using a graphic display for transmit and receive text data, as well as for showing band spectrum and tuning. Just plug in a standard PS2 keyboard and connect to an SSB-capable transceiver like the FT-817 or the PSK-xx transceivers from Small Wonder Labs, and you’ll have an effective digital mode station that goes absolutely anywhere.
