Transmission
Initially its highest frequency transmitter was at 100.3 MHz, with all others sitting in the 98 MHz band. E.g. Limerick was 98.4 MHz at 50 watts and Cork 98.8 MHz at 500 watts (effective radiated power). Within the first year the frequencies were eventually changed, ranging from 100.0 to 101.8 MHz, matching what Today FM is now broadcasting on. Century also broadcast on 1143 kHz AM in Dublin and Cork. These two AM transmitters were introduced some weeks after the station launched.
