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.

This week, we're looking at some interesting developments in the LoRa space, particularly how it's being leveraged for amateur radio applications. We've got a few resources that touch on mesh networking, off-grid text messaging, and the integration of LoRa with APRS. For those experimenting with portable setups or considering resilient communication methods beyond traditional HF, these items offer practical insights. There's also a utility for managing virtual serial ports, something that comes up often when interfacing modern transceivers or microcontrollers with logging software or control applications. It’s a mix of hardware-adjacent firmware projects and mapping tools, all relevant for operators keen on digital modes and self-contained systems.

This week, we’re looking at some practical antenna builds and a handy reference for precise timing. For those operating on 70cm, there are a couple of interesting options: a UHF Double Bazooka Antenna Construction guide details building with RG213, something worth considering for fixed stations needing a clean pattern. Then, for the mobile crowd, especially those on two wheels, a Vertical J-Pole for motorcycle use offers a compact solution for 430-450 MHz. It’s a robust design, which is key when you’re out on the road. Finally, for anyone needing to calibrate their rigs or just curious about propagation, the HF Time Broadcasts and Time Signal Stations List is a solid resource. It’s always good to have those frequencies handy, whether for a quick check or more serious experimentation.
