REDMOSS

| As well as transmitting Absolute, Talk Sport, Radio 5 Live and Radio Scotland, Redmoss (Aberdeen) also relays the Radio 4 Long Wave service at 2kw on 1449kHz to cover the mush zone in the overlap of the Westerglen and Burghead 198kHz service areas. This was a busy medium wave site - no fewer than 6 services were broadcast from here, all of them BBC up until the early 1990s. There are four masts and one self supporting tower at this site. The tower holds the usual array of mobile 'phone antennas and may also be home to the FM Tx antenna of a low powered relay for Original 106 and the DAB Tx antenna, but my visit was before these entered service. |

The second occasion was from 21st January 1984, when UHF BBC 1 and ITV were transmitted from Redmoss, following a fire within the UHF cylinder at the main transmitter for the area at Durris. |
