Ah, Radio 4 is broadcast out of Droitwich. That station first came on the air in October 1934, to improve the quality and coverage of the BBC longwave service. It used a "T" aerial strung between 700 foot masts, powered by six Marconi-Osram CAT14 valves operating in push-pull with 20kV anode potential. They put out a brochure in 1994 called "Droitwich calling", giving the history of the station. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
