Having just come back from my first Four Days in May, hosted by QRP-ARCI, I have a lot to talk about. My first FDIM really exceeded my expectations; true, the Dayton Hamvention is an impressive event, but the activities and … Continue reading
Goodbye, old Paint
I can’t believe that I haven’t made a post since the middle of August. The latter part of summer was absorbed by major family events, and the time just evaporated. Now as winter is approaching, and things have settled down … Continue reading
