This week, we've gathered some interesting material for those of you exploring beyond the usual HF fare. There's a good piece on current satellite operations, covering both LEO and GEO birds, which is always something worth revisiting as the constellations evolve. For the portable ops crowd, we’ve got a practical guide to POTA antennas, focusing on field-friendly designs. And if you're looking to get on 10 meters with a minimal footprint, there's a neat build for a vertical antenna using common hardware store parts. Plus, a rigid 6-meter Moxon construction that won't break the bank, and a look at a long-standing DX group.

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.
