Survey 2: If you could only own one HF QRP radio, which one would it be?

I’m asked a variation of this question several times a month (no kidding!):

“Thomas, if you could only own one QRP radio, which one would you choose?”

If you’ve asked me this question, you’ll know I have a pretty canned response because I feel it’s a very subjective question–one that’s all about one’s own personal preferences–thus the radio I choose may not be the radio you would choose. Since others’ might use this choice to make a purchase decision, I’m uncomfortable providing a simple answer.

I need to better understand the operator before making a suggestion.

Survey #2

The last survey we conducted was so much fun and quite insightful! I’ve a number of surveys in store for the next few weeks. As with the previous, Survey #2 also focuses on HF QRP transceivers.

In this survey, I’d like to explore the topic above. In fact, another future survey will as well, but the case use will be more specific, so please read this survey question carefully:

Imagine, for a moment, that money is no object and that you could own any QRP transceiver in the world. Which one would you choose for all of your various radio activities?

In other words, you can own any QRP radio in the world, but you must use it for all of your radio activities (POTA, SOTA, QTH, Field Day, travel, etc.). Some of you may need a radio that can do all of these things. Some of you may only use it for Field Day, or travel.

In addition, some of you may only use one mode, while others use SSB, AM, CW, and various digital modes!

It’s all about you and how/where/when you might operate!

Please use the form below to make your selection. It’s okay to add a radio that isn’t listed in the “Other” selection, but make sure it’s a QRP (20 watts or less) transceiver, else the entry will be  removed because this particular survey is all about QRP radios.

The survey has no place for comments, but please let us know why you chose what you chose in the comments section of this post!

I will plan to share these results later this week. Thank you!

QRPer Notes: Phil’s Field Antenna Survey Results, Gripping the Palm Pico, and 70’s/80’s Vintage QRP Radios

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!


Field Antenna Survey

Many thanks to Phil (KA4KOE) who shares the results from an informal survey he conducted on the POTA Facebook group. Phil writes:

Tom

I’ve let the survey run for about 3 days on the POTA Facebook group. Sample size was 658 votes. I opted to do a “type” survey and not by manufacturer.

Results:

    1. End Fed Half-wave: 25%.
    2. Shortened vertical with loading coil: 20%.
    3. Full-size vertical antenna / Hamstick style vertical with helical coil:12% each.
    4. Full-size dipole/doublet, etc.: 10%.
    5. End Fed Random Wire: 9%.
    6. Screwdriver motorized coil antenna: 3%
    7. Something tossed in tree and just hoped it would work: 2%

Total: 93%.

Remaining obscure types cut-off below 2% accounted for 7%.

Again, like the poll I conducted previously on radio types, not surprised by the No. 1 spot.

What DID surprise me was #7: I put that selection in the poll types as a joke but 2% of hams throw a wire up in a tree or other support with no forethought and hope it works.


The Palm Pico: Getting a grip!

Many thanks to Terry (N7TB) who shares the following tip:

Hi Thomas,

I was looking at your post re: the Pico Paddle.

I have both the single and double Pico paddle and the KX3 mount. After watching you hand hold your paddles, I came up with a way to make small paddles easier to hold. I have attached a photo. It is a small piece of 3/8 ID pipe insulation to make holding the Pico paddle easier.

Have a great trip to Hamvention.

73,

QRP Radios from the 70s and 80s

Many thanks to Ron (W6AZ) who shares the following video from Mikrowave1 on YouTube:

You asked for it! Here is the birth of QRP and a whack at revealing the top 10 QRP Homebrew Projects and Commercial Radios that started it all. What is all the fuss about low power?

Postcard Field Report: Pairing my new-to-me Palm Pico with the TX-500 at K-6856!

I finally snagged one.

In the world of lightweight, super-compact QRP radio kits, there is one key that is, essentially, a legend: the venerable Palm Pico.

The Palm Pico has a stellar reputation because it’s super lightweight, can retract into its housing to protect it in transport, and can be directly attached to various radios with a specific mounting assembly or via Velcro or magnets.

The Palm Pico has been out of production for some time now and, they’re so highly desired, they often fetch the original purchase price or even higher on the used market. Truth is, so few Pico owners are willing to sell that very few of these keys ever enter the used market.

I was very lucky, indeed, when a long-time Patreon supporter reached out and offered to sell me her Palm Pico and Palm Mini paddles along with a KX2 mounting assembly. She had noticed how my eyes lit up when Josh (KI6NAZ) showed me his Palm Pico paddle on an HRCC Livestream in February.

The price she offered was amazingly low. She told me that she favored some of the other keys in her collection and wanted to give me the opportunity to own them. They were like-new with all original boxes and accessories.

How could I resist? I’m so grateful.

I really look forward to using the Palm Pico and Palm Mini this year. I’m especially eager to hook up the Palm Pico directly to the KX2 with its custom mounting bracket.

I decided to take my Palm Pico on a maiden POTA activation at the Vance Birthplace on April 18, 2023.

Postcard Field Report

I’ve got a load of videos in the pipeline and to keep from falling behind publishing them, you’re going to see more of my slightly shorter “Postcard Field Reports” for the next couple of weeks during my travels.

These postcard reports contain all of the core information, just less wordy.  (In theory!)

Zebulon Vance Historic Birthplace (K-6856)

I arrived at the Vance Birthplace and checked in quickly with the park staff. There were no picnic shelter reservations that day but there was a family with children eating a picnic lunch when I arrived.

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.

Full Results…

Postcard Field Report: Pairing the Elecraft KX3 and Tufteln Random Wire

Believe it or not, the 2023 Hamvention and Four Days In May is only ten days away at time of posting.

Where in the world did the time go–?

If you’re going to Hamvention, I hope to meet you there. When I’m not floating around, I’ll be hanging out at the Ham Radio Workbench/Halibut Electronics table: 3011.

I’m super excited about attending, but I’ve so much to prepare in advance. Every day between now and then is planned out to the max with family activities and projects.

That, and being an introvert (this might surprise some of you), I have to mentally prepare myself for hanging out with 30+ thousand other human beings. I’ll need ten days for that alone. If I appear tired at Hamvention or FDIM, you’ll know why! Ha ha!

Tuttle Educational State Forest (K-4861)

On Wednesday, April 5, 2023, I had a bit of time in the early afternoon to do a POTA activation. Tuttle Educational State Forest was low-hanging fruit as my errands that day took me within a stone’s throw of the park.

I arrived a bit before noon and took some time to record a Hike and Talk video (which will be published in the next couple of weeks).

After the hike, I set up my Elecraft KX3 and paired it with my Tufteln End-Fed Random Wire antenna. Continue reading Postcard Field Report: Pairing the Elecraft KX3 and Tufteln Random Wire

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:

Picnic Blanket POTA on a beautiful spring day at South Mountains State Park

Monday, April 10, 2023, was a spectacular day weather-wise. Spring was out in all its glory making it impossible to stay indoors.

That day, I was driving back to the QTH and made a little detour to the Clear Creek Access of South Mountains State Park.

According to my calculations, I had about one hour to play radio. I did have a firm deadline to hop off the air because I needed to take my daughter to a tennis lesson that afternoon. Couldn’t be late to that!

South Mountains State Park (K-2753)

As I pulled into the Clear Creek Access parking area, I noticed a family of five grabbing picnic supplies from their car.

For the first time ever, there was going to be competition for the one single picnic table at the Clear Creek access!

Actually, there would be no competition at all because there was no way in the world I’d ever take over the picnic table when a family could use it. 🙂

They had a much better reason to use a picnic table than me. Frankly, I was super pleased to see someone else besides a POTA activator using that table. I get a real thrill out of seeing families enjoying our public lands.

Plus, I don’t need a table to play POTA so it was a brilliant excuse to pull the picnic blanket out of the car and set up under a beautiful antenna support…I mean, tree.

For this activation, I decided to use my Penntek TR-45L and, for an antenna, two 28 foot lengths of wire.

Philip shares battery sizing calculator spreadsheet and POTA radio survey results

Many thanks to Philip (KA4KOE) who shares the following two notes:

Battery sizing calculator

I developed the following spreadsheet as a response to all the folks asking “what size battery should I get“?

That’s one of those questions one can’t answer accurately without more information, so I created a spreadsheet.

Click here to download the spreadsheet (Rev 1 updated Feb 1, 23).

Popular POTA radios

I also recently ran a poll on the Facebook POTA group asking what radio they primarily used for POTA. The sample size was 1,148 votes.

Here are the rankings by percentages:

1. Yaesu FT-891: 25%
2. Xiegu G90: 9%
3. Icom IC-7300 and IC-705: 7%
4. Yaesu FT-857D, FT-991A, FT-817/818: 4%
5. Xiegu 6100, Yaesu FT-897D, Elecraft K/KX series: 3%

I cut off the poll at below 3% as there were 60 entries for various radios.

I’m not really surprised by the top 3 rankings.

Do I allow antenna wires to touch tree branches during field activations?

Many thanks to Keysrawk on my YouTube channel, who asks:

Do you usually try to use an isolator or do you often let your wires touch branches by just pulling them over? When you deploy 20m EFHWs, for example, do you try to avoid having an end touch a branch and only have the throw line going over the branch? I tried to go through your videos and look but you don’t often mention how far you pull the wire up and possibly over. Thanks!

This is a great question!

Before I answer, I’d like to add a little context:

  1. I am a QRP operator. The maximum amount of power I use in the field is 10 watts, but 99.5% of the time, it’s actually 5 watts or even much less.
  2. I am answering this as a field operator, meaning I’ll be referring to temporary antenna deployments.

That said, the quick answer is no, during park and summit activations, I do not worry about my antenna radiator wire touching tree branches.

I do isolate the end of my wire antennas from tree branches and leaves, but I don’t worry about other parts of the radiator touching.

Also, all of my antenna wire has some sort of jacket–I don’t run bare wire in the field.

More often than not, when I deploy a longer wire antenna–say, a 40M EFHW–I simply use a tree branch to support the apex of the antenna if I deploy it in an inverted vee configuration. Continue reading Do I allow antenna wires to touch tree branches during field activations?

POTA Field Report: Testing my CP Gear Tactical Aircrew/Pubs Bag with FT-817ND and Armoloq TPA-817 Pack Frame

Last year, during a Black Friday sale, I took a calculated risk and purchased a bag I hoped would accommodate my Yaesu FT-817ND that has been outfitted with an Armoloq TPA-817 Pack Frame.

CP Gear Tactical Aircrew/Pubs Bag

Rod (VA3ON) first introduced me to CP Gear Tactical–a  military pack manufacturer based in New Brunswick, Canada.

I’d had their their Aircrew/Pubs Bag with Padded Tablet Pocket on my wish list since the Ham Radio Workbench podcast episode where we talked about backpacks and pouches. CP Gear Tactical manufactures a wide variety of gear primarily for the Canadian military market. Everything is made either in Canada or the US (or both).

I contacted CP Gear Tactical shortly after outfitting my FT-817 with the TPA-817 pack frame. I measured the frame carefully and asked if the interior padded pocket (which is actually designed to hold a tablet–might fit my radio.

I never heard back from them. I could have called them, but on Black Friday, when it was on sale for 20% off and free shipping, I decided to throw caution to the wind and simply purchase it. My total price in USD was something like $62 shipped.

As soon as I opened the CP Gear pack, the first thing I did was check to see if the FT-817 with pack frame would fit in the interior pocket.

Much to my surprise, it fit it perfectly!

Indeed, it’s as if the pocket were specifically designed to accommodate the FT-817ND/TPA-817 combo.

Even the middle Velcro strap fits precisely in the middle of the radio between the pack frame side extensions. The strap holds the rig securely; once, I accidentally fumbled while holding the bag and even though it was upside down, the FT-817 remained securely inside. The strap held it in place.

The bag has loads of room inside. In fact, you can very easily transform it into a fully self-contained field radio kit.

I actually give a small tour of this pack in my activation video below, so if you’d like to see some of the exterior pockets, I would encourage you to check it out!

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, April 11, 2023, I once again popped by the Vance Birthplace for a leisurely POTA activation–I thought this activation, in particular, would be a good one to test my new Aircrew/Pubs bag!
