N1MM+ on Linux

The N1MM+ contest logging program is among the most popular, if not the most popular, loggers in use by contesters up and down the spectrum. It supports a wide variety of contests and works well with features supporting the largest multi/multi and the smallest “little pistol” alike. It’s constantly under development by a team of volunteer programmers, is frequently updated and is well supported. Best of all, it’s free for the download.

Unfortunately for those of us who choose either the open-source computing life (or are Macintosh users), N1MM+ is only available for the Microsoft Windows operating platform. We have ways, though, Continue reading “N1MM+ on Linux”

Practice, practice

I’ll skip the usual joke about asking for directions to Carnegie Hall, but the advice to practice is just as valid, whether it’s music or ham radio.

Grounding and bonding presentation

Thanks to the South Lyon Area Amateur Radio Club for hosting me Sunday, March 11 for a presentation on grounding and bonding for the average ham. You can find links and resources here, or via the menu to the right under Presentations.

Single-point ground plane for antenna lines

I’ve replaced my current system of shack feedline grounding with a single-point ground plane for the antenna lines coming into the station.

Previously, the HF antennas (off-center-fed 80 meter dipole, 6BTV vertical, and 160-meter inverted-L) all terminated in a rotary coax switch. The switch is grounded to the station ground bus that runs along the back of the operating desk, in turn grounded with strap to the ground rods through the basement wall outside. Other antennas, such as the 160-meter receive loop, six meter beam and the VHF-FM antenna in the attic, connect to their respective devices directly.

The new SPGP consists of a heavy piece of aluminum angle stock with feedthrough UHF connectors. Continue reading “Single-point ground plane for antenna lines”
