This week, we’re looking at a few antenna projects that might spark some interest for those running VHF/UHF. There's a good bit on J-poles, specifically for 2 meters and dual-band operation, using everything from twin lead to copper pipe. We also have a solid 5/8-wavelength vertical build for 2 meters that avoids loading coils, which is always a plus for efficiency. Beyond the hardware, there's a handy utility for Windows users who need virtual serial ports—something that comes up often when integrating various logging or control software. And for those still honing their CW skills, or just curious, a browser-based Morse code decoder that works from images could be quite useful. These selections touch on practical builds and software tools that can enhance both home station and portable setups.

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.
