I've been in ham radio for about 33 years now. My callsign is WB3GCK. I'm particularly interested in low-power (QRP) operation. I'm member of the Eastern Pennsylvania QRP Club (EPA QRP), the QRP Amateur Radio Club International (QRP ARCI), the American QRP Club, the Michigan QRP Club, and the the Adventure Radio Society. I'm also a long-time subscriber to the Internet QRP Mailing List (QRP-L).

I'm a member of the American Radio Relay League (ARRL) and hold a field appointment as an Official Emergency Station (OES) in the Eastern Pennsylvania Section. I am an Assistant Emergency Coordinator with Chester County ARES/RACES (CCAR), which provides emergency communications for the county. I'm also a SKYWARN weather spotter.
