Penmon entered service on the 1st February 1937 with the Welsh Regional Programme on 804 kHz. With the outbreak of WW2 in September 1939, Penmon was retuned to 565 kHz and was used to mask the Irish station at Athlone, but by 1940 was retuned to 767 kHz and transmitted the Home Service. At the end of WW2, Penmon returned to 804 kHz, transmitting the Welsh Home Service. The frequency was changed to 881 kHz on the 15th March 1950 and to 882 kHz on the 23rd November 1978.
From 2nd October 1955 to 20th December 1958, Penmon also transmitted the Welsh Home Service on
94.0 MHz, until the new transmitter at Llanddona came into service. |
