Field Kit Gallery: KM4CFT’s QRP Labs QMX/QCX-Mini Go Kit

Many thanks to Jonathan (KM4CFT) 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, check out this post. Jonathan writes:


Hi Tom,

I thought I would share the two go kits I have. I tend to customize my equipment and supplies before I go on a POTA or SOTA outing but I keep these for the rare occasion when I want to grab a radio real quick. [The first on is my] QRPlabs go kit:

The kit is for my QRP Labs QMX/20 meter QCX mini. It contains everything I need to operate 20 meters CW.

The case is a regular Lowepro case that I got with my KX2 when I purchased it from another ham. I did not realize it came with it so I accidentally ordered an extra from Elecraft which I now use with the KX2 kit [featured in a future Field Kit Gallery post].

The kit uses many components from K6ARK, including the 20 meter EFHW antenna and the retractable paddle.

The battery is a TalentCell from Amazon. I use it because it supplies 12v instead of 13.8v. One of the downsides of the QMX is that it cannot handle 13.8v, so I have to stick with 12.

I keep a cheap pair of earbuds with me just in case but I try to bring a nicer pair of headphones whenever possible.

Hopefully this information is useful to you and your readers!

KM4CFT: A Relaxing Labor Day SOTA Activation

Many thanks to Jonathan (KM4CFT) who shares the following guest field report:


A Relaxing Labor Day SOTA Activation

by Jonathan Kayne (KM4CFT)

September 4, 2023

Days off from work can be a really great thing. And for someone who spends most of his time indoors at a computer, I try to find plenty of excuses to go outside and get some fresh air. Labor Day is one of those days I get off from work, so I decided I would do a SOTA activation, but I wasn’t entirely sure where.

Luckily, there are plenty of tools out there to help with planning a SOTA activation, namely sotl.as, which shows all the summits on a map along with additional information about the summit.

I wasn’t entirely sure which one to pick, so I just searched around and came across Evergreen Mountain, which has the reference designator W0C/FR-076. Doing some research showed that it was about a 2-3 mile hike to the summit from the parking lot, which was perfect. The air around Denver, CO can be somewhat thin and these hikes can be strenuous if you aren’t used to it. I have been living in the Denver area for 2 years and I still am not used to it!

After a small amount of planning, I pack my radio and antenna into a bag along with the usual hiking gear and drive to the base of the mountain. There were a lot of cars already parked there, so I had to park on the side of the road. It seems other people had the same idea that I did!

The trail to the summit of Evergreen mountain was comparatively easy due to the trail being designed for mountain biking. Mountains in Colorado tend to be incredibly steep, which can make them quite the workout, even if the hike is short. This trail consisted of plenty of switchbacks, which made the hike incredibly easy, trading steepness for distance. This was a massive bonus from my perspective!

As you might have guessed, Evergreen Mountain (and the town) get their name from the impressive number of evergreen trees in the area. As you drive towards the town, it almost becomes exclusively pine trees everywhere!

As I walked, I couldn’t help but notice all the fallen pine trees, which concerned me, but I quickly came across a sign explaining the reason.

I really got to enjoy walking through these trees, and listening to the wind howl through the mountains. It also had the benefit of keeping me nice and cool in the reasonable 83° temperature outside.

The trees also blocked the views of the mountains to some extent, but my research showed me that we get plenty of gorgeous views closer to the summit!

Right before the summit loop, I was rewarded with a small glimpse of the views that were to come!

I made it to the summit loop trail, and advanced to the last little bit before the summit. Right before the true summit there is a tenth-mile little trail that leads to a scenic overlook. I, of course, had to go and take a look.

I went back and made it to the summit. The top of the mountain was pretty flat so I just went to what I thought was the summit and set up my station there. Searching around showed that I was well within the activation zone. The area had some nice rocks to sit on as well as trees for me to lash my crappie pole to with para-cord.

I unpacked my gear and started to set up. The gear I brought was as follows:

With SOTA, I have the opportunity to use my VHF/UHF equipment to make some QSOs. I find it quite rare for me to do simplex communication on VHF or UHF these days as I almost exclusively operate on HF. Also, I like to try to operate in the parts of the bands with the lowest license requirement so that the less experienced hams have an opportunity to work me. With this, I can give our technicians a chance to chase SOTA! Continue reading KM4CFT: A Relaxing Labor Day SOTA Activation

Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

Many thanks to Jonathan (KM4CFT) who shares the following guest field report and video:


Chatfield State Park (K-1212)

January 20, 2022

by Jonathan Kayne (KM4CFT)

The honorable Yaesu FT-817/818. You all know it and love it. I had been wanting to get myself one for a while but after just buying myself a shiny new ICOM IC-705, I had been planning on getting myself an 818 in the spring to play around with. December came and I find out that Yaesu was going to discontinue the 818, so I went and bit the bullet and bought one from Ham Radio Outlet.

I had been getting into CW for portable operations lately after wanting to learn CW for a while and my friend Zach Thompson (KM4BLG) had pushed me to learn it. I learned it over the course of two months through an app called “Morse Machine” and listening to Thomas’s YouTube videos while working so as to get used to the exchanges and pick up words. Then I activated and all the rest is history! (If you want to see my 3rd time activating see this video here.)

Why is this important? Because the FT-818ND does not have a narrow 500 Hz filter for CW operation by default, and since I consider myself to be still a newbie I wanted to install a Collins Filter before I take my new 818 into the field. Since these filters are hard to obtain, I went with the build your own route. The method I used has been outlined in this blog and I have made a video of it here.

Now that I had my radio all ready to go with a filter, side rails, and Windcamp Battery, I wanted to get it in the field as soon as possible. Unfortunately due to a snow storm, the temperature in the Denver area was quite cold.

I can handle myself pretty well in the cold if I put on enough layers, but my fingers are another story. I have found that I cannot write properly unless my fingertips are exposed. The solution: do the activation in the car! Continue reading Jonathan takes the Yaesu FT-818ND on an inaugural POTA activation!

New CW YouTube Channels/Videos

In the past two weeks I’ve received a number of video links from QRPer readers who are featuring CW activations in their YouTube videos.

First up is Steve (K9NUD) who has started a new channel featuring his CW activations primarily using a cootie/sideswiper. Steve is doing something I wish I had the time to do which is add CW closed captions to his videos. This makes it easy to follow along. Check out this video:

Jonathan (KM4CFT) recently noted in the comments of my YouTube channel that he made a video of his third ever CW POTA activation. I had to check it out and am glad I did. You get a very good idea of what it’s like on the air as a CW newbie. In other words: not that bad at all! Incidentally, when I looked up Jonathan on QRZ, I discovered we have a mutual friend in Zach (KM4BLG).

Keep up the great work, Jonathan!

Chris (KD2YDN) sent me a link to the following video on his new YouTube channel. In the video I actually get to hear what my signal sounded like during his SOTA/POTA activation. He certainly captured some amazing morning scenery and a gorgeous sunrise from Westkill Mountain:

The ARRL Handbook 100th Edition

The ARRL has announced pre-orders for their new ARRL Handbook. I feel like everyone should have a copy of the Handbook. It’s simply chock-full of useful information–much of which is simply timeless. I still reference the 1994 handbook my buddy Mike (K8RAT) gave me shortly after I got my license in 1997. I feel like it’s important to have reference material like this in paper.

As a side note, I’ve been to a number of shortwave radio broadcast transmitting stations and at each one of them I’ve seen the ARRL Handbook on the Chief Engineer’s shelf. Lots of great radio principles inside.

The book is $80 on pre-order. That’s a lot for a book, but it’s also a LOT of book!

Here’s the announcement from the ARRL:
