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.

Below: the last photo was taken from the top of the Ferris wheel at Codona’s Aberdeen Beach, and Durris can be seen in the distance, centre of the picture.

Station History:

Redmoss was first brought into use for the Scottish regional programme on the 9th September 1938, on 1285 kHz. On 1st September 1939, this frequency was changed to 767 kHz as Redmoss then formed part of the Northern Home Service group during WW2. From 29th July 1945 this became the Scottish Home Service with a new service, the Light Programme, added on 1149 kHz. The Third Programme was available from the launch on 29th September 1946 on 1474 kHz.

With the Copenhagen plan frequency changes, which came into effect on 15th March 1950, the Scottish Home Service changed to 809 kHz, Light Programme to 1214 kHz and the Third to 647 kHz.

1214 kHz was re-assigned to Radio 1 from 30th September 1967. A fourth service, Radio 2, was added on 1484 kHz, on the 1st October 1968, to provide an alternative to the weak long wave signal from Droitwich.

With the Geneva plan frequency reorganisation of 23rd November 1978, Redmoss gained a fifth service. Radio 4 on 1449 kHz. R.Scotland changed to 810 kHz; Radio 1, 1089 kHz; Radio 2, 693 kHz and Radio 3, 1215 kHz. A sixth service was added in the summer of 1981. Radio Aberdeen on 990 kHz.

Redmoss has twice been used as a television transmission site. 405-line BBC TV was transmitted from 14th December 1954 on VHF channel 4 until 12th October 1955, when the high powered station at Meldrum took over the 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.
