History
An article in PO Telecommunications Journal, Winter 75/76 reports that installation of the 300-channel SHF links for the Highlands and Islands scheme was completed in May 1973 with Dunure to Campbeltown. A map with the article indicates Dunure also linked to Brodick. In practice this was a successor to a six-channel VHF link between Dunure and Campbeltown which entered service in 1942, then operating on frequencies around 70 MHz. A 1957 OS map shows "Wireless Station GPO".
The SHF site re-used the original flat-roofed building, with a "Type 4A" tower carrying pairs of dishes for each link. By 2007 there were four dishes for each link - potentially this was a mixture of old and new during migration from 4 GHz to 6 GHz - and the height of the tower had been increased. More recent photos show removal of all but two dishes, both facing Brodick. Ofcom data indicates there is no longer a link to Campbeltown.
