duga-3

When I got my Novice ticket in 1978, the Russian Woodpecker was at its peak. Developed to detect ICBM launches, the over-the-horizon radars known as Duga-1, Duga-2 and Duga-3  caused an incredible amount of QRM on the 20- and 40-meter ham bands. Even Radio Moscow was not immune. The system became operational in 1976 amid…

10B-DXCC QRP

Via Wayne N6KR on the Elecraft reflector: I wanted to acknowledge what is, to the best of my knowledge, a unique feat by Don Bush, WA2TPU. He has achieved DXCC (over 100 countries worked) on every ham band from 160-6 meters, excluding 60 meters, running 5 watts or less for all QSOs. He used a…
