Carl builds the ULTRA-PK “PicoKeyer” CW memory Keyer Kit

Many thanks to Carl who writes:

Hi Thomas,

I’ve grown to love the prerecorded CW memories on my KX2. I’d fallen out of love with my 817ND because it didn’t have them.

Then I saw your video where you used a PicoKeyer. So… I ordered one.

But I messed up and it came in kit format.

So, tonight I built my first Kit-anything in about 30 years.

And, it actually worked!

What a cool little device..

Thank you for sharing this, Carl! This little kit is a lot of fun to build and quite affordable. The end product is one you’ll use for years to come as well.

It’s an amazingly capable little keyer and a proper value!

I purchased mine from this Bay seller in Ft Collins, CO

Pairing my new Xiegu X6100 with a 31 foot speaker wire antenna (and avoiding RX overload)

Regular readers of QRPer.com might question the wording in my title since I’ve already posted several field reports and even a full review of the Xiegu X6100. So why would this X6100 be considered a “new” radio–?

Since I go over this in more detail in the activation video (linked and embedded below), I’ll give you the nutshell version here:

My activations with the X6100 early this year (2022) were all performed using a loaner unit sent to me by Radioddity. I kept that unit for a few weeks, shipped it on, and purchased one of my own.

In February, when I received the X6100 I purchased, I immediately noticed a small mechanical issue with the encoder.

This is the X6100 open. You can see the back of the encoder to the right of the ribbon cable.

I tried fixing it (with instructions received from Xiegu) but in the end had to return the transceiver for replacement.

The X6100 unit in this field report is my replacement–technically, the third X6100 I’ve had in my hands, and this was my first activation using it.

Many of you have asked why I haven’t taken the X6100 to the field more often this year and this is why. I basically didn’t have a functioning unit for most of February, March, and April. Radioddity was quite responsive to my issues with the X6100, but frankly I had a lot going on during that time frame so it took longer than normal to troubleshoot, modify, test, and send back the faulty unit.

Fortunately, the replacement X6100 has no encoder issues other than the brake is very tight. I’m not willing to break the warranty seal on this unit to adjust it, so I’ll just live with a much-tighter-than-I’d-like encoder.

[Update: Bob (W0BNC) points out that the tight brake is due to friction caused by a felt pad under the X6100 encoder knob. The remedy is to pull off the rubber ring around the encoder knob, loosen the set screw, lift the knob slightly off the body, and retighten. I’ll do this when I’m back with the X6100 after summer travels. Thanks, Bob!]

X6100 field kit test

This activation was also the perfect opportunity to test all of the components of a dedicated field kit I’m building around the X6100.

The kit consists of:

  • The Xiegu X6100 QRP transceiver,
  • a BNC binding post adapter,
  • paddles,
  • the X6100 battery charger,
  • a 31′ speaker wire antenna
  • 25 meters of 2mm throw line,
  • a weaver 8oz weight, and a
  • logging pad and pencil.

Everything, save the antenna, fits in my Red Oxx Hound EDC pack.

Eventually, I’ll replace the speaker wire with some thinner Wireman stuff and it should all fit in the Hound pack, albeit snuggly!

I’ve decided that the X6100 will live at my parents’ home in the NC foothills, so I’ll always have a field radio kit available while staying there overnight.

On May 9, 2002, an opportunity opened up in the afternoon to finally take my new X6100 to the field! Continue reading Pairing my new Xiegu X6100 with a 31 foot speaker wire antenna (and avoiding RX overload)

Yaesu FT-817ND: A morning QRP POTA activation at New River State Park

No better way to start a QRP day…

I took the family on a multi-day camping trip at New River State Park in April 2022.  During that trip, I made an activation of New River each day and also fit in a quick SOTA activation (click here to read an overview). I didn’t film all of my on-the-air because some of that radio time was spent sitting around chatting with my family and even some neighbors at the campground.

Since I’ve already posted a summary of that fine trip, and since I’m traveling today, I’ll keep this field report brief(er).

Morning POTA

One thing I love about POTA while camping is how effortless it is to do morning activations. You simply roll out of bed and get on the air. That easy.

The following field report was for an activation session on the morning of April 29, 2022.

I spent the early morning that day brewing a couple cups of coffee and catching up on my QRP Quarterly and QST, then I took Hazel on a short hike.

Back at the campsite, I served Hazel some breakfast and then she enjoyed her first of many morning naps. (I swear that dog is only awake a max of one hour per day–!). Continue reading Yaesu FT-817ND: A morning QRP POTA activation at New River State Park

Scott Builds a clever Icom IC-705 Paddle Mount

Many thanks to Scott (KK4Z) who shares the following project from his blog KK4Z.com:

Paddle Mount for the IC-705

I kinda like the idea of being able to mount your paddle to your radio when operating portable. You can use the weight of the radio to help prevent the paddles from moving around and it frees your off hand for other tasks. We see examples of this with the Elecraft KX series of radios and there are some adapters for radios such as the Yaesu Ft-817/818.

I really like my IC-705. It is probably my best radio for POTA/potable operation. I think the only time I would leave it home is if weight became a problem or I needed to exercise one of my other radios. Recently, Begali came out with a mount to attach their Adventure paddle to the IC-705. It is a sweet set-up; however, the approx. $400 USD price tag got me looking for other alternatives. I have nothing against Begali, I own three of their paddles, and they are superb instruments. I think I wanted to tinker, and this gave me a good excuse.

For paddles, I have a set of Larry’s (N0SA) SOTA paddles. I love these paddles. When I go on an activation/Portable Operation, I bring these and my Begali Travelers. If I was going to do a SOTA activation, I would just bring Larry’s Paddles. Next was a trip to Tractor Supply Company (TSC) for a sheet of 16 ga. Steel. That set me back $16. I cut it to 3″ by 3 1/2″ using a cutoff wheel on my grinder.

I already have a stand I made out of 1″ x 1″ angle aluminum so I cut this to fit behind it.

The blue on the metal is Dykem Blue which is a layout fluid. In creating this project, I am only using hand tools. Power tools consisted of a grinder with a cut-off wheel. a hand drill, and my trusty Dremel tool. Here is a picture of me giving the mount a rough finish with a file.

Rough conditions but serious QRP POTA fun at New River State Park

The New River (Photo by K4TLI)

You might recall from my previous field report that I took the family on a camping trip at New River State Park in April 2022.  During that trip, I made an activation of New River each day and also fit in a very fun SOTA activation (click here to read an overview).

Note that anytime you’re performing an activation over multiple days at any one park, you can only have one activation per UTC day.

The following brief field report is essentially my “Part 2” from April 28, 2022. Since I’d already worked well over my ten contacts in the previous activation session that UTC day, all of these contacts were simply icing on the cake!

Keeping this one brief(er)

I’ve an insanely busy day today, what with exam study, errands, splitting firewood, and prep for our summer travels.

That said, I wanted to squeeze in an activation video and field report because the rest of the week is even crazier. Continue reading Rough conditions but serious QRP POTA fun at New River State Park

A comprehensive review of the Penntek TR-35 four band QRP transceiver

The following article originally appeared in the April 2022 issue of The Spectrum Monitor magazine:


“Look at this, Tom! Only the stuff I need and nothing more,” cheerfully noted my good friend and Elmer, Mike (K8RAT).  It was Field Day two decades ago, and Mike was gazing at his TEN-TEC Scout. I glanced over, and agreed. “So simple and so effective,” Mike added.

I’ve never forgotten Mike’s sage words. That Scout (Model 555) was about as simple as a then-modern HF transceiver could be:  it had a total of three knobs––one for AF gain and IF bandwidth, one for RIT and Mic gain, and an encoder. It also had three mechanical switches on the front: one for power, one for TUNE and NB, and one for CW speed and RIT. It also had an analog SWR/power meter. The Scout used plug-in band modules for each HF band and featured a large segmented bright green LED frequency display that was characteristic of so many TEN-TEC rigs of the day.

And Mike was right. For those of us who appreciate radios with a simple, uncluttered, and an almost utilitarian interface, the Scout was, in vintage parlance, “the bee’s knees.”  And that the Scout also performed beautifully was just icing on that cake.

When the Scout first appeared in 1994, embedded menu options and spectrum displays were not yet commonplace among amateur transceivers. Embedded menu items can open the door to near granular level control of your radio’s functionality and features. Then again, if those embedded menus aren’t well thought out, it can lead to awkward operation practices in the field, during a contest, or even during casual operation.

As a radio reviewer, I spend a great deal of time sorting out embedded menu functionality and design. Perhaps it’s for this reason that I so enjoyed reviewing a radio that bucks this trend and reminds me of a time that was simpler, not to mention, easier.

Enter the Penntek TR-35

The new Penntek TR-35 is a four-band CW-only QRP transceiver that is available both as a kit ($279) and as a factory assembled and tested unit ($379). Penntek transceivers are designed and manufactured by John Dillon (WA3RNC).

All of his transceiver kits are available at his website WA3RNC.com.

I was first drawn to the TR-35 after reading the opening paragraph of the product description:

“Compact but powerful 4-band, 5-watt CW transceiver kit that uses no tiny push buttons, and without those seemingly endless and hard-to-remember back menus. There is a knob or a switch for every function!”

Sold!

I considered buying and building the TR-35 kit, but I wanted my eventual review––this one!––to focus on the radio’s functionality and performance. So a factory-assembled and tested unit was right for this purpose, just so that any performance issues wouldn’t be a result of any shortcomings in my kit building skills.

I decided to reach out to WA3RNC and ask for a loaner. John very kindly sent a factory built TR-35 to me along with return postage and a very flexible loan period (thank you, John!). Continue reading A comprehensive review of the Penntek TR-35 four band QRP transceiver

Leo’s first SOTA activation included impressive SSB QRP DX and a CW pile-up!

Many thanks to Leo (DL2COM) who writes:

Hey Thomas,

[…]I just wanted to give you a quick update on my 1st SOTA activation (May 18th). We spent a few days in the south of France with the extended family. From the garden of the house we rented we were constantly looking towards a beautiful mountain front and it turned out to be SOTA summit FR/CR-205 (726m, 2382ft). So I decided to try and activate it since we had enough people around who offered to watch out for our kids.

Next morning: 6am my dear XYL and I started our ascent.

What a wonderful scenery with morning mist covering most of the mountain landscape and the sun in perfect shape for an early hike.

At around 7:45am we arrived at the summit and I started throwing up my arborist weight into pretty much the only suitable tree available. Continue reading Leo’s first SOTA activation included impressive SSB QRP DX and a CW pile-up!

SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome!

Although I live in the mountains of North Carolina and am surrounded by SOTA summits, it’s much easier for me to activate a park rather than a summit.

Parks can be quite easy: find the park on a map, drive through their main entrance, find a good picnic table to set up, and next thing you know you’re on the air! Of course, wildlife management areas and game lands can be more tricky, but typically you can drive to the activation site.

Summits–speaking as someone who activates in North Carolina–take much more planning. If it’s a new-to-me summit, I typically need to:

  1. find the GPS coordinates of the true summit
  2. map out the drive to the trail head
  3. read through previous activation notes (if they exist) to find out
    • what type of antenna/gear I might pack
    • and any notes I might need to find the trail or bushwhack to the true summit (quite often published, well-worn trails don’t lead to the actual summit)
  4. look up the trail map and make sure I have a paper and/or electronic copy
  5. pack all needed gear for the hike, activation, and emergencies
  6. sort out the time it will take to travel to the site, hike the full trail to the summit, activate, and return home

If you ask most any SOTA activator, they’ll tell you that the planning is part of the fun.

It really is.

One summit I’ve had on my activation list for ages is Craggy Dome (W4C/CM-007). Out of the higher summits in this region, it’s one of the easier ones for me to reach from the QTH. In fact, as with Lane Pinnacle, I could simply hike from my house directly to the summit (although one way to Craggy might take the better part of a day). The trailhead is about a 50 minute drive, and the hike about 30 minutes.

SOTA notes and All Trails indicated that Craggy Dome’s trail isn’t always easy to follow and that it’s steep and slippery.

Craggy has been activated loads of times, though, so I wasn’t concerned at all.

Living here and knowing how much brush there was on the manway to the summit, I knew that Craggy would be a pretty easy summit if I could activate it after the parkway re-opened for the spring and before the mountain “greened-up”; about a five week window.

Meeting Bruce

My schedule opened up for an activation of Craggy Dome on the morning of April 21, 2022 and I was very much looking forward to it.

I wouldn’t be alone on this hike either. Bruce (KO4ZRN), a newly-minted ham, contacted me and asked if he could join me on a hike and simply be an observer during a SOTA activation.

Fortunately, timing worked for him to join me on this particular SOTA activation. Continue reading SOTA in the Clouds: Pairing the Elecraft KX2 and MPAS Lite for brilliant QRP fun on Craggy Dome!

Dale’s solution for enhanced CW field ergonomics

Many thanks to Dale (N3HXZ) who shares the following guest post:


Ergonomics of Operating CW in the Field

by Dale (N3HXZ)

About a year ago I started getting active in Parks On The Air (POTA) and Summits On The Air (SOTA). I had always been an avid hiker and backpacker, and though I am getting up there in years (recently retired!) these amateur radio opportunities were just the medicine I needed to rekindle my passion for the outdoors and amateur radio.

Thanks to Thomas (K4SWL) and his blog post and videos I was able to quickly come up to speed on the basics and get out into the field for CW activations.  I quickly discovered that operating CW in the field is quite different from operating at home. The creature comforts of a good chair, a level and spacious operating table, and isolation from the weather makes for a great experience in the shack, but is not available in the field, especially if you are backpacking to your destination. My early activations were sitting on a rock, or the ground, and using only a clip board to mount my rig (Elecraft KX2), locate my CW paddle, and place a notepad to record QSO’s.

While simple, this operating setup poses problems. Attaining and maintaining a flat workspace is tough in the field in order to keep things from shifting or falling off the clipboard, especially if you are not firmly seated. There is not enough space to set your wrist in order to steady your CW operating, and the notebook pages can flap in the wind, or the wind can blow your logbook clear off the table while operating. I realized I needed to upgrade my mobile station! Continue reading Dale’s solution for enhanced CW field ergonomics

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?
