The Saint Lawrence Valley repeater Council (SLVRC) or Comit de Coordination de Fr quences de la Vall e du St-Laurent enlightened me when I clicked their Notes on the 222 MHz Band link. Internet research leads me to a web site hosted by our neighbors to the north. Trying to keep an open mind, I realized that most of what we purchase in the way of electronics (including amateur gear) is probably manufactured in China anyhow, so I investigated further. He suggested that we consider building a 220 repeater from two TYT- TH9000 Mobile transceivers! Oh I had to overcome the perception that these were cheap Chinese radios and the concept would not be feasible due to technical or quality issues. Ģ While pondering this dilemma, an innovative idea was suggested by KD0 TLS (Todd). The two boards alone would cost $ and would only be a starting point for a repeater. who sell VHF FM exciter and receiver boards. The story is very different today with the only choice available being Hamtronics, Inc. Back in the day you could obtain boards, modules or entire 220 band repeaters from companies such as SCC and VHF Engineering. When it was working, this repeater was probably the best performing 220 repeater in the Twin Cities area due to its excellent location and 80 watts of RF power. This repeater had served the club and the ham radio community for many years and was built from Spectrum Communications Corporation (SCC) modules mounted in a VHF Engineering enclosure. It all started when the Twin Cities repeater Club's aging 220 repeater on MHz failed due to what appeared to be audio problems. īuild a repeater from TYT- TH9000 Mobile Transceivers Now it was a simple matter to peel off the sticker covering the 9-pin serial port cut-out andġ Build a repeater from TYT- TH9000 Mobile Transceivers Part 1 Modifying the TYT- TH9000 (D).
