First POTA of 2026
So my first attempt to take out the QDX on its first POTA ended up in failure because I forgot the power cord on Tuesday Jan 6th. I was kind of bummed but it is what it is and POTA was not the primary reason for my trip to McHenry that day. I rectified that problem and did the typical ham thing of making extra cords and placing thing in backup locations. Yes there is a set of barrel cords in the car now just in case.
I rectified this on Friday afternoon Jan 9th and did a simple setup in one of the parking lots, very serene and tranquil spot where I could hear a woodpecker pecking one of the trees.
I used my usual Subaru POTA station setup for the winter but this time I used the 20m Hamstick with a mag mount on the roof. I was able to get an SWR of 1.26:1.
This was the first outing for my recently build QRP Labs QDX Rev 4 80-20m transceiver. On the bench with 12.3v I was able to get 3w out on 20m, but I used a new battery that had a barrel connector on it and it was not fully charged as it measured 12v. I was able to get out with 2.10 to 2.01W and that remained constant for a little over and hour of solid FT8. When I got home, the battery voltage dropped down to 11.8v. I was very happy that the QDX remained cool to the touch!
I was amazed how soon I hit a pileup on 20m FT8 and ended up with 42 QSOs in just over an hour. One of them ended up being a duplicate but did land two P2P contacts and one in Spain.
I ran a slightly different setup than when I use my IC-705. I did not use SDR-Control for ICOM, instead I did USB-C into the QDX and ran WSJT-X Improved with the Alternate Layout and Gridtracker. All of these are great pieces of software and I support and use all of them regularly.
So now I need to finish up the QMX+ that has landed on the workbench. As always I am using Wavelog running in Docker on my Raspberry Pi 5. Guest view is here.
