THE LETHANHILL TRANSMITTER is a UHF and BBC National FM relay station that serves areas of South and East Ayrshire.

For television purposes, the station relays transmissions received directly from the Darvel UHF main station.  With the exception of Radio 4, FM radio transmissions to the site also originate from Darvel but are relayed to Lethanhill via the station at Girvan on the Ayrshire coastline.  Both Lethanhill and Girvan lie south-west of Darvel, the FM signal therefore effectively bypasses Lethanhill en route to Girvan before being directed back north-east to Lethanhill.  Radio 4 transmissions meanwhile are received directly from Divis.

The station has only transmitted digital television since Digital Switchover in May 2011 and carries only the main Public Service Broadcast (PSB) multiplexes.

STATION HISTORY

Lethanhill was opened by the Independent Television Authority (ITA) on 31 January 1969 as a late entrant to their VHF transmitter network, completing a trio of relay stations built to improve 405-line television coverage in areas served inadequately from the Black Hill transmitter.  Preceded by the opening of the Rothesay transmitter on 30 August 1968 and Rosneath on 13 December 1968, Lethanhill was the last of these three relays to enter service.

The station was however the first of these 405-line relay sites to commence UHF transmission and doing so as the first relay of the Darvel UHF main station.  Both BBC and ITV UHF transmissions from Lethanhill commenced on 23 March 1973, less than four months after the opening of its parent station.

Its fellow 405-line relay sites did not commence UHF transmission until 1976, Rosneath also relaying Darvel for this purpose with Rothesay remaining a dependent of Black Hill.

The phased shutdown of the 405-line service commenced in 1982, a process which saw many of the last stations to have opened amongst the first to close, although closures were not specifically in reverse order of opening.  Nevertheless, having originally been the last of the three Black Hill 405-line relay sites to open, Lethanill was the first of these to close, doing so in October 1982, with Rothesay and Rosneath ending transmission in 1983. 

 

Above: Although presently a typically remote farnland setting for a transmitter site, Lethanhill was in fact previously one of the Ayrshire mining villages, referred to collectively as 'Ayrshire Miners Rows'.  The Lethanhill mining village existed between 1851 and 1954, after which it was completely vacated and subsequently demolished with the area reverting to farmland.

The only indications of the former village are the commemorative plaque seen in the above image, along with a War Memorial further back on the approach track and further downhill the former school house which is now a private residence.
