Palstar TR30A HF Transceiver

This week, we’re looking at a few practical builds and modifications that might spark some winter workbench activity. There's a detailed guide for a multi-band portable vertical, the PAC-12 Antenna, which uses easily replaceable loading coils—something that comes up often when you’re trying to cover a lot of ground with minimal gear. For those running an Elecraft KX2, a modification for adding audio I/Q output is presented, useful for external SDR software or a spectrum scope, which can really enhance signal analysis in the field or at the home station. We also have a look at a 40-meter reversible Moxon design, a practical approach to directional antennas without needing a rotator, and a simple 80-meter CW transmitter build for those who enjoy getting on the air with minimal parts. Finally, there's a discussion on optimizing keyboard setups for CW contesting, a small detail that can make a big difference in a pileup.
