ATV repeater Cologne, DB0KO

DB0KO-Testbild alt

This repeater located in Cologne since 1980 (licence holder DF9KH) had an FM-ATV output on 1280 MHz (only antenna and Sat-TV-Receiver attached to any TV set needed). It was intended to be a "Multimedia" repeater from the start, so besides the ATV inputs from 70 cm to 3 cm there were RTTY, SSTV and FAX inputs on the 2 m band (not active any more). That needed a complex control system working computerized.
