Transmitter

500w ex-Halifax aircraft transmitter (as used by Radio Sutch)

(from September 1964)


An  ex-US Navy  General Electric transmitter (3.5Kw) used for music broadcasts on 1034kHz (290m) (but announced as 299m), while a surplus Ministry of Defence Airforce Cossor transmitter was used to air the sponsored religious programmes on 1605kHz (188m).

The original Radio Sutch transmitter was retained for making contact with the landbased office

(From mid December 1964)


(Later the Cossor transmitter from Shivering Sands was transferred to Knock John Fort when  a second station was being planned.)


Aerial

Originally a horizontal wire aerial was strung between scaffold poles mounted on one of the Fort’s towers.


In June 1965 a 200' (61m) aerial mast was installed on top of one of the 117’ (35.6m) high  towers on the Shivering Sands Fort, giving a total aerial height of 317’ (96.6m)
