During the Berlin Blockade AFN Berlin started broadcasting around the clock. After the building of the Berlin Wall AFN Berlin then stayed on the air 24 hours until July 1994. AFN Berlin had three stations: * an AM station at 1107 kHz * an FM station at 87.85 MHz (adjusted to 87.9 MHz at a later stage, called 88FM) * a TV station on UHF channel E29 (US channel 25) broadcasting in NTSC (thus requiring a multistandard set for German viewers) with a low power transmitter limited to southwestern districts of Berlin
