QRP Eric Falkof, K1NUN For the North Shore Radio Association, 08-Apr-2006
Sixty Years of QRP History in One Slide! Once radio “happened,” it was big! But Hams (and others) wanted it small. “Compaction” began, and in the 50s, we began to see transceivers Then TenTec opened the gates to the modern era
Transceivers helped with compaction Collins KWM-1: the first transceiver and 175 W (1955ish) Cosmophone (UK); 35, 50, and 1000 W (1957ish) Gonset G-76: 100 W AM (1959) Ten-Tec Powermites: 2 W (1966ish) Heath HW-7: 3 W (1972)
So, what is QRP? > 100 W > 10 W > 5 W > 1 W
