This is a follow-up to my previous article on the POTAPlus web browser extension. With the help of “ham-proxy-app.exe” and Omnirig, POTAPlus provided rig control to QSY to POTA spots and set the correct mode. With ham-proxy-app.exe, POTAPlus would also log your contact and add your spot to POTA. As you may recall, POTAPlus did…
This is a short followup to my previous article on antenna interactions. My original plan was to mount two wire antennas on a sidearm on the tower. The first is an 80M / 60M fan dipole mounted in an inverted vee configuration and the second is an 80M EFHW mounted as a sloper. I have…
If you have listened to Dave Casler on YouTube or read his column in QST, you probably know his first rule of antennas: “everything affects everything”. I recently had an eye-opening, learning experience when installing a couple of 80M wire antennas. While I thought that there could be some interaction between the antennas, I never…
This month’s article will highlight an application of AI (Artificial Intelligence) to ham radio. Most modern ham radio transceivers and receivers have built-in DSP (digital signal processing) capabilities. One of the most useful implementations of DSP is for noise reduction. The analog RF, IF (intermediate frequency) or AF (audio frequency) signals are converted to digital…
This month’s article will highlight some resources and method that I have used for learning Morse Code. There are many others available if none of these work for you. I started to study Morse Code in 2022. After learning the alphabet, I got distracted with other radio activities and stopped routine practice. I re-started my…
