Retired Bioemedical Engineer exploring homebrew DIY amateur radio antennas, QRP projects, low power communications using minimalist antennas, aquarium sump filters and fluidics, and vintage WWII era radio restoration.

If you're interested in a WONDERFUL QRP club - I highly reccommend the North American QRP Century Club... the NAQCC. No dues or anthing... and they have REALLY fun monthly sprints.. and they do a lot of activities throughout the year. See:
