In my never-ending fascination with broadcast transmitters, I bring you the Harris\/Gates BC1H. This is an updated model of the BC1G, the main difference being the solid-state audio and oscillator sections in the later H model. This design uses the simple 833 parallel final and 833 push-pull modulator<\/p>\n\n\n\n

Harris\/Gates BC1H Transmitter running at 1,000 watts into the antenna.\u00a0 Like many old tube transmitters, this sounds great on the air.\u00a0 The transmitter was made in 1975 and is in backup service.\u00a0 For a 37 year old transmitter, it runs like a champ and comes on consistently.\u00a0 Like the preceding Gates BC-1 models, this transmitter is rugged and reliable.\u00a0\u00a0 My only comment is the transistors in the solid-state driver section are no longer available.\u00a0 If that were to become an issue, one can always look up the tube audio driver from previous versions (T and H models).\u00a0 It would be a shame to throw away a good transmitter for lack of a couple of transistors, but I know some who have done just that.<\/p>\n","protected":false},"excerpt":{"rendered":"
