The POTA Babe Gets a Partner!

13 Comments

Those of you that read the final article for my spring-break Florida POTA trip know that I recently reconciled with someone dear to me. This man, Glenn W4YES, has moved to Savannah, Georgia and we are in a relationship. He is a CW op and the person behind CW Innovations’ Comprehensive ICR course. He knows how much I love POTA and joined me Friday, May 3rd for an activation.

I could have resumed my quest for 60 new-to-me parks. However, I figured we had enough “new” stuff going on with a new activator and a different set up for Glenn. POTA tends to throw the unexpected at you already and the more variables you add, the more opportunities there are for mistakes (er, learning opportunities) and/or hilarity to ensue. So I chose to return to Evans County Fishing Lake (US-7464), a site already known to me, for our dual activation.

What a gorgeous day! Sunny skies and 71 degrees! The drive is a short (about 50 minutes) and easy one to this park.

Given Glenn would use QRO equipment and didn’t have a chair or knee board like myself, I chose one of the few spots with a picnic table. The site looks out on Bidd Sands lake. We could have shared my QRP set-up but decided to activate at the same time which necessitated two sets of equipment.

I chose familiarity over reinventing the wheel when it came to picking equipment for Glenn – I grabbed my Yaesu FC-50 tuner and Yaesu FT-891 rig from my ham shack and the Pacific Antenna 2040 trap dipole antenna and SOTABeams travel mast from my equipment stash. This was the set-up I used for POTA before I went QRP with the KX2 and Tufteln EFRW last May. It wasn’t long before a station was set up on the picnic table for Glenn. However, the antenna was another matter.

Glenn’s set up

When I grabbed coax for the antenna, I forgot the connector is a BNC connector which is why I have a coil of RG-174 in my stash. Instead of grabbing that RG-174, I grabbed my 50’ coil of RG-8x. (Doh!) That coax is extremely heavy for the SOTABeams travel mast and, after adding an adapter for the BNC to SO-239 connector, the antenna was hanging over precipitously. It just goes to show how well-made and durable the SOTABeams travel mast is. I was mortified as I like the best possible arrangement for my antennas but Glenn wasn’t. He knew what we had was good enough for contacts (see his QSO map down below) and his thinking turned out to be correct.

20-40 Pacific Antenna

While Glenn finished getting everything in order for his activation, I began setting up for mine. I know this park allows antennas in the trees so it wasn’t long before the trusty Tufteln EFRW was installed. Daisy and I chose a shady location near the antenna, got comfortable, and began my activation.

As Glenn was running QRO (the power I usually run on my Yaesu FT-891 is 75 watts) on 20 meters, I began working other bands. I initially wondered if I would have any difficulty running a QRP station so close to a QRO set-up, but I didn’t. Continue reading The POTA Babe Gets a Partner! →

Field Radio Kit Gallery: KF6EFG’s Not so QRP box(es)

4 Comments

Many thanks to John (KF6EFG) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post.

Hello Thomas,

Thanks for posting so much interesting content on your website, and helping to host the Ham Radio Workbench! I have gotten a number of ideas for my ‘Fat Boy’ kit from you guys.

I am sending a couple of images of my not-so-lightweight field boxes.

I have been under time constraints while at work, so I developed a series of boxes that can be used in the field while on lunch break.

The core is a black watertight box and a 21ft mast. I can make do with my truck battery in a pinch, and did until I purchased an external battery.

Since I took these images, I have moved the RG-174 and choke to the black box, making black box a complete kit, sans power.

I am playing with a small netbook and will become FT-capable soon!

Black Box:

Orange box:

  • 50ft RG-8x coax cable
  • Bioenno Li4po battery, charger in box.
  • Tufteln Choke adapter
  • Tufteln EFRW antenna cut for 20m.
  • 25 ft RG-174
  • Amazon small packing cube with assorted adapters, small bungee cords, and tools.

Not shown:

  • 21ft fiberglass pole, in a PVC pipe case. Case doubles as a base and short guy point for the mast.
Please don’t mind my messy truck bed!

Green box:

  • Tripods
  • Wolf River Coils WRC-1000
  • Extra 21ft fiberglass pole.
  • Construction twine for disposable guying.
  • 2 extendable whip antennas

Also pictured above:

  • Adjustable antenna clamp
  • Homemade trailer reciever antenna stand off

The Amazon medium packing cube contains:

  • Various adapters
  • Various power pole wires and other ends (clamps, cigarette lighter, ring)

Tool kit:

  • Multi tool
  • Tape
  • Connectors (one screw on UHF, ring, butt)
  • 4 Radial wires , 17 ft.

This box resides in the truck bed for use when I want to use a vertical antenna.

I usually end up on my lunch break at the local RC flying club. I work at a multi use airfield, and the club has graciously allowed me to use their field when no flying activity is present.

73,

Will the Yaesu FT-891 fit in the CP Gear Tactical Aircrew/Pubs bag?

5 Comments

Many thanks to Rick (K3RTK) who writes:

Thomas,

I watch your videos often and enjoy them thoroughly! Quick question : I really like CP Gear Pack Aircrew Bag that you reviewed on one of your recent videos. I was wondering if the Yeasu FT-891 would fit in the padded compartment where you are storing the 817. I know you now have a FT-891, but for reference, the 891 is about 2 inches deeper, 1/2 in taller and almost an inch wider. Thanks in advance!

Rick K3RTK

You’re not the only person to ask this question, Rick! Several people have contacted me to find out if the FT-891 will fit the CP Geat Tactical Aircrew/Pubs bag. 

The answer is yes. See the photos below:


In fact, the Aircrew bag fits the ‘891 with a wee bit of room in the padded pocket to spare.

Keep in mind that the FT-817 or FT-818, when outfitted with the Armoloq TPA-817 Pack Frame (see photo below), is actually a bit bulkier than the FT-891 without a pack frame or side rails:

I think the Aircrew bag would make for a very handy FT-891 field pack!  Thank you for your question!

Finally did it! First POTA activation with my new-to-me Yaesu FT-891

23 Comments

Yep. I finally did it.

Over the past few years, I’ve received numerous requests to check out the Yaesu FT-891 HF transceiver. Almost all of my ham friends have one and they are widely considered one of the best 100 watt HF radios for park activators. Indeed, I bet it is *the* most popular 100W radio among POTA activators.

I’ve been tempted to ask Yaesu for a loaner model and I even came within one button click of ordering a new FT-891 from DX Engineering during a Black Friday sale in 2020.

I’ve resisted the FT-891 temptation, though, because I tend to use smaller, more portable QRP radios in heavier POTA rotation. I knew if I purchased an FT-891, it just wouldn’t get a lot of field use. It also demands a beefier field battery due to its current requirements and, frankly, it’s so rare I run more than 5 watts (and 5 watts is the lowest power setting on the ‘891) I would simply have a lot of radio for my needs.

A few weeks ago, however, a friend reached out because he wanted to sell his FT-891 and 30Ah Bioenno battery and downsize to a smaller field portable radio like the Xiegu X5105. Long story short, we worked out a trade/purchase which included the ‘891 and his battery. I had been thinking about a large capacity battery to use as a backup in the shack, so this worked out well for both parties.

Zebulon B. Vance Birthplace (K-6856)

On Tuesday, March 14, 2023, I once again had an hour to fit in an activation at the Vance Birthplace before picking up my daughters at school. I’ve really enjoyed the opportunity to play radio at Vance so much during this particular school term; next term, it’s unlikely I’ll have this opening, so I’ll enjoy it while I can!

I deployed the Chelegance MC-750 vertical again. I’ll admit that it’s so convenient keeping an antenna in the car trunk/boot that can be made resonant so easily from 40 meters and higher.

I was going to show the antenna deployment again in my activation video, but received a call and decided to deploy the antenna while finishing up the phone call. It only takes a couple of minutes to set up.

Next, I connected my 15Ah Bioenno battery to the FT-891. Even though I was only using five watts, the ‘891 needs more capacity than the 3Ah packs I normally carry with my QRP rigs.

I also connected the Begali Traveler key–I do love this key (thanks again, Jackie!). Continue reading Finally did it! First POTA activation with my new-to-me Yaesu FT-891 →

André’s All-Season Yaesu FT-891 Go-Box

3 Comments

Many thanks to André (PY2KGB/VE2ZDX) who writes:

Hi Thomas!

I’m writing to share my idea for a cheap and easy to build go box. It’s not for a QRP rig, but the concept can be applied for the ft818, for example. Check out this YouTube video:

I’ve been operating under snow with this box, in “ninja” style.

Because if I wait for it to stop snowing here I’ll do nothing for 3 months, hehe!

Guest Post: “Why I Quit QRP (and maybe shouldn’t have)”

16 Comments

Many thanks to John (VA3KOT) who shares the following guest post which was originally published on his Ham Radio Outside the Box blog:

Why I Quit QRP (and maybe shouldn’t have)

by John (VA3KOT)

For many years I was a dedicated QRP operator. I even took my “Portable QRP Operation” show-and-tell out on the road for presentation at ham clubs in my area. Then along came the dark, gloomy depths of the solar cycle minimum. My forays out into the Big Blue Sky Shack became a series of disappointments. Maybe the odd QSO here and there, but most often I came home with nothing but a few RBN spots after multiple CQ calls. Something had to change.

“Why QRP?“

I began to ask myself “why QRP?”. It’s a valid enough question. Just what is so magical about an output power of 5 watts? Why not 1 watt, 3 watts, or 20 watts? It has often been said that 5 watts of CW is equivalent to 100 watts of SSB. There is a mathematical proof but I won’t repeat it here. So shouldn’t 100 watts of SSB be considered QRP?

QRP has a cult-like following. There are several online organizations dedicated to it. I am a member of some of them. QRP certainly has an appeal for those of us who like to operate in the great outdoors. Perhaps the greatest advantage is that an entire station can be stuffed into a couple of pockets – antenna and all. And a QRP rig sips battery power so slowly that some can be powered all day on a 9-volt alkaline battery.

I laid the blame for my lack of portable QRP QSOs on poor propagation. Maybe my signal just wasn’t making the trip. The propagation demons in the sky were swallowing my signals, burping and grinning down at me with a smug, malicious gleam in their eyes. QRP-’til-I-die operators shrug that off as “the fun of QRP”. Not getting any QSOs is fun?

In hindsight, there could have been another explanation. The Reverse Beacon Network was constantly reaffirming that my puny emissions were making it up to the ionosphere and being refracted back down to the Earth. So why were so very few people responding to my CQs? I have a theory about that. Maybe, back then, random CQs only appealed to a small number of people. I asked myself how often I responded to random CQs. Hmmm, not too often!

Anyway, images of QRO rigs were dancing around my head whispering sweet messages of temptation in my ear. “Yes” I said to myself; “that’s the answer. Maybe I just need to blow more watts into the air and I will fill up my logbook!” But first a roadblock. I had to persuade “senior management” that I should invest in a new radio.

Enticing radios in the periphery

46 Comments

Since my early days in the world of radio, there have been radios I found very intriguing, but have never owned. I’m sure I’m not alone in this regard.

These radios have enticed me, but not enough to pull the trigger…you know…to actually buy one.

Not yet, at least.

Here’s a small sampling of radios I currently window shop:

The Elecraft K3/K3s

There’s a reason this particular radio series has been on so many DXpeditions: it packs a lot of performance and is efficient for its size.

I’ve owned all of Elecraft’s QRP radios and I love them. I know I’d like the K3 or K3s as well.

There are a couple reasons why I haven’t purchased a K3 or K3s. First of all, I already own a KX3 with a CW roofing filter and a KXPA100 amplifier. In a sense, I feel like this is a rough equivalent of the K3. The KX3 doesn’t have all of the features or options of the K3 series, but it has everything I need as a primarily portable op. Secondly, the price of the K3 or K3s–depending on the installed options–range anywhere from $1,100 – 2,900 used. The lower priced ones tend to be QRP and lack some of the performance options.

That said, if I ever landed a super deal on a K3, there’s a decent likelihood I’d buy it.

The Yaesu FT-897D

I know what it is about the FT-897: it looks like it means business. I’ve always found the rugged design of the ‘897 appealing even though a friend jokes that it’s the ugliest radio Yaesu’s ever made. Of course, folks who buy an 897 aren’t looking at the form, they’re going for the function.

Mark discovers an affordable IP67 rated protective case for the Yaesu FT-891

2 Comments

Many thanks to Mark Hirst who writes:

Thomas,

I got a new FT-891 recently and wanted a protective case for taking it out into the field.

A mixture of internet searches and Amazon algorithms turned up this very affordable case which closely matches the size of the radio, as the enclosed photograph shows.

It uses the familiar pick and pluck foam, although in two layers.

The base layer is a bit thin, so I might put a layer of rigid plastic over it to stop the feet of the radio pushing down to the outer case.

I prioritised the side wall thickness opposite from the carry handle, as the case is designed to sit on its side like a briefcase.

Via Amazon USA ($29.31)

Via Amazon UK (£20.99)

Mark

Wow, Mark! I do love the size of this case and the fact that it fits the FT-891 so perfectly.

Recently, I’ve been thinking about building out a case to hold one of my smaller QRP transceivers (the KX1, KX2, or MTR3B) in the field to be used when it’s raining. Perhaps this has been on my mind because I’ve been enjoying nearly 5 straight days of rain and fog! A case like this would be an affordable solution and I wouldn’t feel terribly bad about drilling through the case to mount antenna, key, mic, and headphone ports.

Thank you again for the tip!
