New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

There are few things that make me happier than radios and pets.  On Saturday, January 7, 2023, I got copious amounts of both.

On the way back to the QTH, I stopped by Table Rock Fish Hatchery (K-8012) for a nice, leisurely POTA activation.

En route to Table Rock I gave some though to the antenna I might deploy. In the end, I decided I’d once again set up the Chelegance MC-750.

There was no question which radio I’d use: it’d be the brilliant Penntek TR-35 packed-up in its new field kit!

Table Rock Fish Hatchery (K-8012)

Table Rock Fish Hatchery isn’t open on Saturdays, but that really isn’t a problem because the picnic area where I set up shop is open 24/7.

And the best part about Table Rock? The welcoming committee…

These two dogs are so incredibly sweet and always a highlight of activating Table Rock. You may have seen them in my previous field reports and videos. Continue reading New Penntek TR-35 Field Kit, Canine Welcome Party, & Brilliant 20 Meter POTA Conditions!

Field Report :POTA Activation K-0228, Stuart B. McKinney National Wildlife Refuge, Great Meadows Unit

by Conrad (N2YCH)

January 21, 2023

Parks On the Air’s Support Your Parks weekend event for winter 2023 is the third full weekend in January and I found myself without my Jeep. I sold my ten-year-old Jeep Wrangler and my new Jeep wasn’t due to be delivered until the following week, leaving me without my “POTA activation vehicle”. I ended up borrowing my XYL’s MINI Countryman to activate K-0228, but let’s face it, a MINI is not a Jeep. It didn’t have all of my “stuff” in it. I needed to get creative about what to bring along with me that would fit easily in the MINI, yet work well enough to activate the park.

I started with my backpack kit which contains an Elecraft KX3, battery, Signalink and computer (for FT8 and logging).

It includes everything I need to transmit and it’s easy to toss in the car. I just needed to decide on what antenna to use. Since it’s winter here in Connecticut and pretty cold outside, this would be an “in-the-car” activation and without the Jeep, my antenna options were limited. I could have brought my Sotabeams Tac-Mini which could fly my PackTenna EFHW up about 20’. However, anchoring the mast would be a challenge in the cold weather. In the end, I decided to bring my Buddipole tripod and nested mast, which are compact and fit in a small bag which fit right in the passenger seat.

Some ham radio retailers have a limited number of new Yaesu FT-818NDs incoming

As you, no doubt, know by now, Yaesu recently discontinued the FT-818ND QRP transceiver. Within a day of the announcement most US retailers sold out their remaining inventory. There may still be new units at some UK and EU retailers at time of posting.

Ham Radio Outlet

Many thanks to John (KC8RZM) who writes:

I notice HRO, after having no listing for new FT818NDs for a few days, it’s now back being listed as being available for ordering (though not currently in stock).

John was correct, of course. I checked HRO’s FT-818ND product page and see that they’re listed as out-of-stock yet you can still order one for $699.95 US they seemed to have increased the price to $799.99 since yesterday (Jan 24, 2023).

I reached out to HRO to gather more information. HRO Sales Manager, Steve (W4SHG), replied:

We have been told more may be coming, we have no idea how many or when they may arrive.

So it sounds like they’re taking orders for an unknown quantity of radios they’ll be taking into inventory at some point in the future.

Martin Lynch & Sons

It also appears ML&S have new FT-818ND inventory arrive by end of January. They are allowing pre-orders to reserve these units. The price is £624.95 and they include a free MyDEL Leg Peg kit. Not a bad deal!

Should you bite the bullet?

If you’ve been considering a new-in-box, fully warranted FT-818ND, it might be worth reserving one of these units.

I would certainly not panic-buy an FT-818ND because there are so many tens of thousands of these in the wild I think there are deals to be found on the used market. I do suspect there may be a temporary increase in prices on the used market, but in a few months they’ll go back down.

Other retailers?

If you know of any other ham radio retailers who will be receiving new FT-818 stock, please comment below.


Here are some tips from readers from the comments section:

Wimo (Europe)

Leo (DL2COM) comments: Wimo was out of stock a few days ago and now seems to have a few new ones. Click here.Scott (K4IBX) comments: Thomas – thanks for all you do! Nevada Radio still has stock w/shipping and today’s exchange rate about $705+/- delivered via FedEx to US.

My winter kit-building cycle

What is it about winter that engages my inner kit-builder–?

I go through this cycle every year: when outdoor temps plummet, I fire up the soldering iron and start building kits that have been sitting on the shelf for the previous three seasons.

I used to think that I built more kits in the winter because I spent more time indoors, but that’s not actually true. Reality is, I probably spend more time outdoors in the winter than I do in the other seasons…save fall, perhaps.

I actually have a QCX+ transceiver kit that a kind reader generously donated to me (thanks again, OM!). I can’t wait to dig into this particular build, but I’m forcing myself to wait.

Until I finish building and installing my Murphy Bench (check out this HRWB podcast episode where we take a deep-dive) I don’t have a dedicated space for a good multi-day transceiver kit. At present, I have to take over the dining room table and as you might imagine, the others in my family aren’t incredibly pleased with a semi-permanent workbench in the middle of the house.

I’m making my Murphy Bench a priority and dangling the QCX+ as a reward for completing the build. Wish me luck!

I’m curious: Do you find that you also do more kit-building during certain seasons? What kits or other projects are on your horizon?Please comment!

PackTenna linked 20/40 meter EFHW in stock (for the moment)

Update (one hour after publishing this post): It appears they’ve already sold out again. Sorry! I’m sure more will be produced in the near future. 

Last night, during a recording of the Ham Radio Workbench podcast, George (KJ6VU) noted that he had just replenished stock of the Packtenna 20/40 End-Fed Half-Wave.

This particular antenna has a tuned 20 meter radiator and an additional 33′ of antenna wire finished off with strain loops and gold banana connectors. To operate on 40 meters, simply plug in the additional wire and connect the strain relief loops to the supplied S-Hook clip.

These antennas are made in batches and sell out very quickly (indeed, during the show recording George sold nearly half his stock).  This morning, there are still a few left.

I mention this since I know a number of readers have been waiting for this particular linked EFHW to be in stock again.

Hike & Talk Session: Conquering the CW Doldrums

A couple years ago, I started making Hike & Talk video sessions covering in-depth topics that are challenging to answer via email or even long-format blog posts.

When I receive a question from a reader and think to myself, “I’d rather answer that in-person than write a reply,” I make a note to do a Hike & Talk session.

These sessions are not scripted, outlined, or formatted in any way shape or form. When I make a Hike and Talk video, I imagine that I’m chatting away with you informally as you join me on a hike or walk.

All this to say that these long-format videos aren’t for everyone, so if it doesn’t sound like your cuppa’ tea, it’s okay to skip it! I promise, I won’t be offended.

Conquering the CW Doldrums

On January 11, 2023, I was driving back from Raleigh and decided that a quick POTA break was in order. That morning, I read an email from a reader and it was on my mind as I drove to Tuttle Educational State Forest. It was a long email, but here are the relevant bits:

Hi Thomas […]I’ve been studying CW on my own for about four months now. I know you advise joining a group like the Long Island CW Club to learn CW but my work schedule simply doesn’t allow for this. I travel frequently and have team members across the globe so my schedule is a mess. I have so little free time.

[…]I’ve been using various CW apps, CW recordings like W1AW and your videos to practice CW. I can’t stress how much your videos have encouraged me along the way because you make this all seem so achievable. I download your videos from Patreon and listen to them when driving, flying, during layovers, and in the evenings in my hotel room. Many times I just listen to your video audio as I would a podcast.

I am not at a point where I can understand all of the contacts you receive, but I do get maybe 1 out of 3. It’s a real thrill to know I decoded a callsign on my own. I see a day when I will do CW activations.

[…]I’m writing though because I feel like I’ve reached a barrier. I know all of my characters and numbers and I continue to do regular CW practice, but I feel like I’m not learning. Like my brain has stopped soaking up the code. It’s discouraging. Do you have any advice for getting through this?

I’ve received similar emails and comments in the past which is proof that you’re not alone if you can relate to this reader.

I’ve certainly been there, too!

Hike & Talk

In this video I will talk about the CW Doldrums, how I related to them, and how I work through them myself.

I include (against my better judgement!) a very long side story about my path to learning French. It relates, but perhaps not how you might think.

Instead of editing my videos, I always try to include chapter markings in the YouTube timeline so you can skip over any sections that aren’t of interest to you.

You’re going to need a few cups of coffee or tea for this one. You’ve been warned!

Thank you

Thank you for joining me on this Hike & Talk session!

If you’re experiencing or have experienced the CW Doldrums yourself, let us know how you work through them in the comments section.

The important part is to know that you’re not alone and that, in fact, the Doldrums are truly a healthy sign that you’re learning CW and your brain is doing it’s thing!

As always, a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support.

Thanks for spending part of your day with me on the trail!

Cheers & 72,

Flying With Ham Gear and Navigating TSA

Many thanks to Michael (N7CCD) for sharing the following guest post:


Flying With Ham Gear

by Michael (N7CCD)

I often get asked “how hard is it to fly with ….”, or “what does TSA say about …” as my job has me flying a fair amount throughout the year. In fact, I’m writing this now while waiting to board my flight for a week in Georgia and Alabama, after having just gone through TSA.

In a recent QRPer post by Thomas, I posted a comment about my frequent travel with ham gear and Thomas gave me a gentle “hint hint” nudge to write up my experiences on the matter. I thought this trip would be a good time to share my experiences in traveling with ham gear in my check-on baggage, as well as my carry-on baggage and my process for each. I’m always interested in learning from other’s experiences, so if you have some ideas for the good of the community, please share them in the comments below!

Before starting this article, and out of curiosity, I checked my past calendar and figured out that I passed through TSA screening about 26 times in 2022. I would say that, since starting my current role four years ago, I have at a minimum hit that number each year.

To address the main question I get about ham gear (antennas, radios, batteries, etc.) and TSA, surprisingly TSA has very little interest in any of it.

In all of my trips through the x-ray machine, TSA has never once pulled my bag out to further investigate what was inside. They have asked about my thermal camera, but never my ham gear. Full disclosure, I am TSA Pre-Check which does exclude me from having to remove laptops, iPads, etc. However, on a recent non-business trip with my wife and kids to visit family in Mexico, I wasn’t pre-check and they still didn’t care about any of my radio gear.

Since I’m limited on the amount of stuff I can physically carry on the plane, and my work gear requires me to check a bag anyway, I have divided my radio gear between what I want with me on the plane, and what I’ll just pick up when I collect my bag at baggage claim.

I have settled on a hard sided suitcase after having to replace some of my work arc flash PPE (personal protective equipment) when baggage handlers cracked my arc flash face shield. After upgrading to a hard sided suitcase, I started adding more ham equipment I would otherwise worry about getting damaged. In the image below you can see what, at this point, I’ve included in my checked bag.

From top left to bottom right: Raspberry Pi kit (more photos on that below), CWMorse paddle in a dollar store container with cable, Buddipole PowerMini, charging cradle for HT, SignalStuff mag mount for HT in rental car, hand mic for HT for use in rental car, throw line and weight, AlexLoop w/ Amazon Basics tripod, US Road Atlas

The idea behind the Pi and AlexLoop antenna is I can work HF digital no matter where I am. This is more fun than watching TV in a hotel, but also gives me digital capabilities to send emails or texts over HF if I am stranded without service of any kind. The mag mount and HT hand mic allow me to use my HT in my rental car as a mobile radio. The same SignalStuff antenna on my HT can be transferred to the mag mount easily once I step into the car.

“On All Bands” Three-Part Field Antenna Series

Last year, DX Engineering asked if I would consider being a guest contributor on their new blog, On All Bands.

I’m a big fan of DX Engineering, so happily accepted.

My first contribution turned into a three-part series on choosing the right antenna for field radio activities.  I put quite a bit of time in it and enjoyed the process!

You can check out this series and any of my future contributions, by clicking here.

DX Engineering has a number of contributors and I’ve enjoyed reading through the site archives. Click here to check out the On All Bands home page.

Pairing the Penntek TR-45L and Chelegance MC-750 on a swift POTA activation

Friday, January 6, 2023, was a beautiful day and my route took me within 10 minutes of South Mountains State Park (K-2753).

Of course, I had to activate it!

In truth, I had only a short window to do the activation, but I knew it would be seriously fun.

I’d packed my Penntek TR-45L and Chelegance MC-750 for the trip and was looking forward to pairing the two.

My TR-45L actually has the built-in Z-Match manual antenna tuner, but I wanted to, once again, configure the MC-750 as a resonant antenna (much like I did in my previous activation).

I also had my new VK3IL pressure paddle along for the ride and wanted to see how nicely it might work with the TR-45L.

If I’m being honest, it was a bit strange not to use a wire antenna at this particular park because South Mountains has some very large old-growth trees that are ideal for hanging antennas.

That said, I also had my choice of spots to deploy the MC-750 vertical. Continue reading Pairing the Penntek TR-45L and Chelegance MC-750 on a swift POTA activation

Confession time: I bought a brand new Yaesu FT-818ND

I know what you’re thinking:

“But Thomas, don’t you already have two FT-817NDs–?!”

Why yes, I do!

Before you label me as a hopeless radio addict (I am, but let’s shelve that for a moment),  let me explain myself…

First off, why two FT-817s?

If you’ve been a reader for very long, you’ll already know that I’m a huge fan of the FT-817/818.

I won’t go into the reasons here because I published a very long-format article on this topic last year.

Suffice it to say: I believe the FT-817/818 an effective, durable, versatile, and frequency agile multimode radio.

I purchased my second FT-817ND because:

  1. I wanted it for full-duplex satellite work (funny: many satellite enthusiasts call a pair of 817s the “Yaesu FT-1634”)
  2. The unit I purchased was like-new with all original accessories and side rails for $350 shipped.

Although my first FT-817ND has a Collins narrow CW filter installed, I decided to build one for this second unit as well. That way, I could grab either radio on the way out the door to activate a park or summit.

So why the new FT-818ND?

It was always my plan to eventually replace out one of my FT-817NDs with an FT-818ND. Here are the reasons:

  1. I was having difficulty finding a TXCO. The  FT-818ND has a TCXO-9 high-stability oscillator built-in.
  2. I wanted one of my two radios to be a late model.

I had planned to buy a Yaesu FT-818ND sometime in 2023. Possibly at the 2023 Hamvention.

When Gavin (GM0WDD) informed me that Yaesu was discontinuing the FT-818ND on December 28, 2022–only moments after the announcement was made–I immediately hopped over to DX Engineering and purchased one. I realized that the remaining inventory of new radios would be depleted in short order and I was right. By the following day, all major US retailers were out of stock.

Are FT-818ND prices going to soar?

No. I don’t think so.

The FT-817 and FT-818 have been on the market since 2001. In that time, Yaesu has sold bazillions of them. Seriously. These pop up in the classifieds and at hamfests all the time because there are so many floating around out there in the wild.

The FT-818/817 is sort of the opposite of a rare, limited-production-run radio. If you’re looking for a used ‘818, I think you’ll find that the prices are relatively stable.

I would discourage you from paying a premium for an FT-818ND.

Next steps with my ‘818ND

I am going to set this unit up for POTA and SOTA activations; it can do double duty for satellite work.

I’ll remove the Portable Zero side rails from one of my other 817s and attach them to the FT-818.

I initially planned to yank the narrow CW filter out of my 2nd Yaesu FT-817, but that just seemed cruel. If/when I sell that radio, I would like to give the buyer a narrow CW filter option.

I decided, instead, to order a Collins filter from Japan and filter board from Artur in Poland and build yet another 500Hz filter.

I also purchased RT System’s programming software and cable for the FT-817/818. I’ve adopted RT systems for all of my other VHF/UHF radios, so it’ll be easy to load, change, and clone all of the frequency memories. I’ll be nice having both SOTA calling frequencies and repeaters pre-loaded on my radios.

I’ve thought about actually making a no-edit video of building/installing the CW filter and side rails.

Speaking of videos about building a narrow CW filter, though, check out this one Jonathan (KM4CFT) published only recently.

Zero buyer’s remorse

While the announcement by Yaesu may have prompted me to pull the ‘818 trigger a few months early, I have no regrets whatsoever.

The only challenge I’m going to face down the road is trying to sell the “extra” FT-817ND.

Then again, I’ve thought about keeping the third one decked out in the TPA-817 pack frame (see photo above) and lending it out to local POTA/SOTA newbies who want to test out the healing waters of QRP.
