In Europe we used at 70s years a teletype machine, type RFT (from German Democratc Rep.) in wooden case, convertor ST 5 and a oscilloscope for tunning...TCVR SOKA DX 505.. ( club station OK1OAZ.) Very strong tingle in head was after contest, from noise of the teletype machine..And hard work with log. 73!!! Frantisek, 7X0RY http://www.ok1df.nagano.cz/7x0ry
