My understanding of it was that it was operated by all kinds of stations including the Observer Corps. using old TR9s. The idea was that the aircraft made a Darky call and if anyone with a crappy radio heard it and replied then they knew roughly where they were because the range was so low. There were also beacons on some mountains in Wales that operated on the same frequency, so if you heard it you must be too close!
