Denny, I would stay away for those Maxar's. They were never a very good radio, but they were a lot cheaper than buying a Maxtrac or Mitrek at the time they came out.
I would stick with trying to find a 42-50 MHz Maxtrac or other synthesized radio. If you really want something in a crystal controlled radio, I would try and find a GE MVP or Motorola Mitrek 42-50 MHz radio. The MVP's are a front mount or under dash radio and about the same style and age as the Maxar, but are a much better radio. The Mitrek in my opinion is a big step up over the MVP, but they are little harder to interface to, since they are a rear mount radio with a remote control head. Let me know if I can be of any help. Joe - WA7JAW If you find a synthesized radio and need help programming it, let me know and I may be able to give you a hand or program it for you. --- In Repeater-Builder@yahoogroups.com, Dennis Ashworth <k...@...> wrote: > > Tnx Eric - that may be good advice.
