THE TOROSAY TRANSMITTER is one of four UHF main stations in the STV Central region and serves the South West Highlands and Islands.  This area includes the Isle of Mull, where the transmitter is based, as well as neighbouring islands and parts of the west coast of mainland Scotland.

It shares main UHF transmitter status in this region with Black Hill, Craigkelly and Darvel and is the basis of one of the five post-Digital Switchover transmitter groups along with the aforementioned and also the Darvel relay station at Rosneath.

Entering regular service on 11 June 1976, Torosay was the last of the four UHF main stations in the region to commence transmission.

Under analogue, Torosay was classed as a UHF main station in somewhat anomalous circumstances in that it was fed from Black Hill and accordingly numbered as a relay of Black Hill (105.10).  It still retains this number post-Digital Switchover but is now a main station entirely independent of Black Hill.

(A similar situation exists with the UHF main station at Bressay in the Shetland Islands which is numbered 134.02 as a dependent of the Keelylang Hill main station on Orkney).

Torosay does not currently broadcast any radio services.  The nearest carrier of BBC National FM, Local FM and BBC National DAB radio is the Torosay UHF relay at Oban on the mainland west coast.

TRANSMISSION STRUCTURE

Due to the site benefitting from a ground elevation of 427 metres (1401-ft) above sea level, Torosay requires only a 52-metre (171-ft) tower to carry its main UHF transmitting aerial, with a reserve aerial carried on the shorter neighbouring tower.
