This week, we've pulled together a few items that touch on some persistent challenges and evolving technologies in the shack. There's a practical look at mitigating common-mode issues, something that comes up often when dealing with feed lines and antenna installations, especially for those running higher power or operating portable. We also have a couple of pieces exploring the expanding role of Software Defined Radio, both as a standalone system for advanced modes like Digital Amateur Television and as a valuable companion to traditional transceivers. Finally, a quick nod to the wider RF spectrum with a public safety audio feed, a reminder of the diverse signals out there. It’s a mix that should offer something for those experimenting with RF, optimizing their home station, or even considering satellite operations.
