Charles, Welcome to the world of 6 Meter repeaters. They can be a lot of fun. In Missouri you are a little better off frequency and duplexer wise due to your 1.7 MHz split between transmit and receive frequencies.
For radios it depends if you are a GE or Motorola person. If you are a GE person, the Mastr II is the repeater of choice, followed by a Exec II. If you are a Motorola person, the Micor or MSR2000 are the repeaters of choice, followed by the Mitrek. For a duplexer, any good commercial duplexer rated at 1 MHz spacing should do the trick. Andrew LDF Heliax for feedline, and my favorite antenna is a pair of DB Products loops, if you have enough tower space. If not a single loop will work pretty good. I tend to shy away from fiberglass (Stationmaster style) antennas for use on 6 Meter repeaters. Your worst enemy will be anything rusty or loose on the tower. If you are on a busy site near other radios and man made noise, you most likely will not need nor want to use a preamp on the receiver, but if you are out in the middle of nowhere on a solar site with a good quiet solar controller a preamp may be of benefit. Good Luck with your project. Joe - WA7JAW --- In Repeater-Builder@yahoogroups.com, "Charles Rader" <kc5...@...> wrote: > > I am tossing around the idea of building a 6 meter repeater.
