Glenmarksie was one of a number of SHF link sites bringing TV and radio to North West Scotland. The site was originally built by the BBC to provide four channels of 625-line colour TV and in the late 1980's the BBC PCM/Nicam radio distribution.
The feed started at Rosemarkie, onto Glenmarksie, Falls of Conon, Sgurr Marcasaidh, Glen Docherty, Melvaig and onto Eitshal and Skriaig. To save on the cost of putting in electricity, access road, maintenance etc in this remote and mountainous area, Glenmarksie and Sgurr Marcasaidh were passive repeaters. Glenmarksie is a plane reflector, while Sgurr Marcasaidh was a passive repeater having 2 dishes mounted back-to-back, connected, but with no powered electronics. Falls of Conon was an active repeater, adjacent to a road and an electricity substation with dishes pointing towards Glenmarksie and Sgurr Marcasaidh. More information about the link system is provided in a BBC Engineering article linked at the foot of this page.
In between Rosemarkie and Falls of Conon lies Glenmarksie. Its purpose was to reflect the SHF signals from Rosemarkie to Falls of Conon, an active repeater about a mile away in the valley below. |
