VA2NW’s Icom IC-705 Field Kit

by Tom (VA2NW)

I got my start in field radio with Summits on the Air (SOTA) a little over 12 years ago. With SOTA, size and weight are the main considerations when building out a field kit; you have to haul everything up a mountain after all.

These days, my focus has shifted to Parks on the Air (POTA). With POTA, activations I don’t need to include any hiking at all. With that in mind, I decided to build a field kit that focused on high quality gear to maximize performance and enjoyment while minimizing my impact on nature (i.e. no wires in trees, no spikes in the ground, etc).

The ideal use case for this kit is a rural POTA park or a low difficulty SOTA summit that involves zero to twenty minutes of hiking or walking for a medium length activation of one to three hours with a maximum setup and teardown time of ten minutes. This article showcases the various items in the field kit and provides some context on the decisions that were made about what I’ve included.

Radio

After buying and trying many QRP radios, I decided that I wanted an all band all mode QRP radio with a waterfall display, SWR sweep, tuning knob (Sorry KD1JV), CW filters, optional battery pack which can be removed or replaced easily in the field, full 5W output, reasonable power consumption, plenty of options for accessories, a large community, well written manuals, availability for purchase without a long backorder, and easy configuration with touch screen and/or intuitive menus.

The Icom IC-705 fit the bill.

Several of the Xiegu brand radios come close to meeting these requirements and are much more budget-friendly. However, I have encountered some issues with my Xiegu X6100 becoming too hot to touch in the first half hour of a normal CW activation, and that was concerning enough to me to take it out of contention for being my main portable transceiver.

Key

For the key, I chose the CW Morse double lever paddles with steel base. The base does add weight to the kit, but this key fits my operating style perfectly. I key with my left hand and write with my right hand, so having a solid base that keeps the key from moving when in use helps me avoid having to hold the key with my non-keying hand. The paddles are good quality and won’t break the bank. I really like the feel of the hard stop when the paddles hit the contacts.

The paddles are easy to use with or without gloves which is a huge plus where I operate in Canada.

Antenna and feedline

Throughout the years, I’ve experimented with many different types of antennas from simple wire antennas to magnetic loops to yagis to verticals and more. I’ve gone on many group outings and have gotten to see a lot of options. I live in Canada, and I wanted something I can use all year round. As I realized in the field last November with my JPC-12 ground spike vertical, you can’t drive a ground spike into the ground when the ground is frozen. I’m a big fan of wire antennas; however, I’ve never found a support system that I liked. Tree branches can break easily, especially in the winter, damaging the trees. Additionally, not all locations have suitable trees.

Telescoping poles are an alternative but need some sort of support, usually with something in the ground. Magnetic loops don’t require anything in trees or in the ground, but dealing with the narrow bandwidth and constant re-tuning makes searching and pouncing quite a chore. An antenna that can cover the most activte POTA bands, 20m and 40m, is also important to me. My last requirement for an antenna is one that doesn’t require an external tuner; manual tuners require some fiddling and auto-tuners generally require some sort of power supply and coax jumper. In both cases, external tuners generally have some amount of insertion loss.

Those requirements led me to focus in on a tripod mounted vertical antenna. There are several options in this space including the SuperAntenna, Slidewinder, Wolf River Coils, JPC-12 with tripod, REZ Ranger 80, and others. I ultimately picked the REZ Ranger 80. The key features that led me to choosing the REZ Ranger 80 were the quality, the bands supported, the online reviews, and the availability to ship to Canada without backorder nor complicated ordering process. It’s built like a tank, can go all the way down to 80m, has glowing online reviews, was in-stock, and I could take care of the customs and import fees at time of purchase with DX Engineering.

Golden Hour QRP POTA Activation with the REZ Ranger 80 Portable Vertical Antenna

September 11, 2023 Thomas Witherspoon 6 Comments

On Sunday, August 20, 2023, en route to check in with my parents, I popped by Lake James State Park for a little early evening POTA fun.

In the car, I’d pack the Elecraft KX2 kit and I still had the REZ Ranger 80 vertical antenna system on loan from REZ Antennas (it’s since been returned to them).

The last time I deployed the REZ was on Mount Mitchell in some pretty sketchy weather. While I recorded a couple of short videos, I didn’t record a full activation video since we were having a family picnic that day.

Before sending the Ranger 80 back, I wanted to fit in a proper activation showing how I deploy the antenna, how I tuned it for the first time, and how it might perform on the 40 meter band.

Lake James State Park (K-2739)

It was golden hour at Lake James and the park was bustling with activity. There were kids running around, parents chasing them, and several families cooking out at the numerous picnic sites.

I sought out a location that was private and quiet mainly because the Ranger 80 antenna has four 31 foot radials, thus a large footprint; I didn’t want children, pets, or anyone tripping on the ground radials.

Fortunately, one of my favorite spots overlooking the lake was free, so I could simply set the Ranger 80 up in the woods where folks weren’t walking.

The Ranger 80 is super easy to deploy: simply extend the vertical, attach it to the top of the base, then attach the stainless spike to the base and plunge the entire thing into the ground. Next, you deploy the four radials and connect it to the base of the antenna.

It only takes a couple of minutes especially since the counterpoises are wound using the over-under method. I simply tossed each line into the woods and didn’t worry if they were all lying perfectly on the ground.

Note to REZ: Consider offering optional high-visibility counterpoise wires–for those of us setting up in busy parks, it would make the ground radials more conspicuous to passersby.

Next, I needed to tune the Ranger 80 for the forty meter band.

Typically, when I use a sliding-tap tuning coil style antenna like this one, I turn on the radio and move the coil until I hear an audio peak, then I fine tune it by sending a “dit” on the radio, checking the SWR, and adjusting the coil slider.

That evening, though, I had my RigExpert AA-35 Zoom antenna analyzer so I set it to continuous SWR monitoring and adjusted the coil until I achieved a good match. Easy.

I should add here that when you use an antenna like this frequently, you learn where the best tap points are on the coil thus tuning becomes easier. My friend Alan (W2AEW) actually made a PVC rig for his coil antenna (click here to check it out).

With the antenna all set up and ready to rock-and-roll, I simply hooked up the Elecraft KX2, my VK3IL pressure paddles, and prepared the logs.

It was time to play radio! Continue reading Golden Hour QRP POTA Activation with the REZ Ranger 80 Portable Vertical Antenna →

POTA on Mount Mitchell: The new REZ Ranger 80 and how to use the Over/Under method to coil wire and cable

August 14, 2023 Thomas Witherspoon 1 Comment

The REZ Ranger 80 antenna system ships with everything you need, including a nice backpack.

Back in March, I received an email from Mike Giannaccio (W5REZ) the owner of REZ Antenna Systems–he was curious if I’d like to check out his REZ Ranger 80 antenna system.

At the time, my plate was pretty full, so he arranged to send it to me on loan in July.

If you’re not familiar, the Ranger 80 is a portable vertical antenna with a tuning coil at the base that employs a sliding tap for tuning. The Ranger 80 will cover anywhere from 80 – 15 meters without needing any sort of external matching device (like an ATU).

If you’re familiar with the Wolf River Coils antenna systems, then you’re familiar with this type of vertical antenna. The difference is that the Ranger 80 is built to what I could only describe as MilSpec standards.

Much of the Ranger 80’s components are CNC machined from premium materials. It sports a Delrin body, black anodized 6061 aluminum, and all stainless steel hardware.

This is not a featherweight antenna: it has the heft to match the caliber of materials used in its construction. It’s not an inexpensive antenna either–it’s currently about $560 US at DX Engineering.

The base of the Ranger 80: note the beautifully CNC-machined holes for the four counterpoises.

The Ranger 80 is also rated for 500W SSB and 250W CW/Digital–in other words, quite a bit more power than I’d ever use in the field, but this design will make activators and field ops happy that like to push some wattage.

I was curious how easy the Ranger 80 would be to deploy and tune, so on Sunday, August 6, 2023, I took it to one of my favorite parks on the planet.
