Main transmitter – 50Kw RCA Ampliphase BTA 50H
1 x 10Kw RCA BTH 10H
1 x 5Kw RCA BTA 5G (converted for use as a 10Kw shortwave transmitter, repaired after the raid in August 1989 and used on 558kHz medium wave)
1 x Orban Optimod AM 9000A unit to process the transmitter's signal, giving near FM quality.
In October 1989 (following the raid) transmissions were on very low power, less than 1Kw, achieving a signal range of less than 100 miles from the Ross Revenge. However there was a significant increase in power to 4Kw, when transmissions resumed on 9th January 1990, following three days of engineering work.
