Information from RCAHMS (DE), February 1999

Situated on the S side of the A9 trunk road at Crakaig and Lothbeg Point. The main site covers the whole of Crakaig Links on the S side of the railway. The accommodation camp and remote reserve are situated at Crackaig farmsteading.
Many buildings are still extant, including the two transmitter (Tx) and two Receiver (Rx) blocks, mast bases, hut bases and lookout posts. This site underwent several modifications during the war which resulted in the duplication of some of the buildings. The equipment for this station came from Thrumster (ND34SW 37))

Elements of the site were surveyed and recorded during the East Sutherland Coastal Survey, conducted by GUARD in Spring 2010.
Remains were recorded, spread out over c. 3 km of coastline and included bunkers, concrete bases for several masts, remains of hut foundations and lookout posts. The site was recorded as deteriorating as many parts are located in exposed positions and sand is being blown away from a bunker at the western end of the complex. The site was recommended for future monitoring.<2>

Further information on individual bunkers, lookout posts, and accomadation blocks, is available in each of the linked records. <3>

A plan of the Radio Station at Loth was received via Martin Briscoe. The site closed on 15/03/1944. He reports that there are three lookout posts along the coast and they possibly predate the use of this site as a radar station. <4><5>

Photographs were contributed by Martin Briscoe via the Highland HER Flickr group.<6>
