This week, we’ve pulled together a few items that touch on practical antenna work and some digital modes. There’s a good look at a multi-band portable dipole, something that comes up often for field day or SOTA ops, detailing a switching arrangement for 40 through 15 meters. We also have a piece on building and testing 50 MHz traps, comparing different capacitor types—useful for anyone experimenting with 6-meter antennas. For those running APRS, a comprehensive symbol table is included, which is always handy for interpreting what you see on the map. Finally, we’ve got a mention of open-source firmware for LoRa transceivers and a popular Android application for APRS tracking, both relevant for modern portable and mobile setups.
