John, Your correct, the Master Pro was a very good radio, in the shop that I worked at we did the service for a freight delivery fleet of over 200 Master Pro's. The only part that I did not like was in the UHF transmitter where it had a varactor diode tripler. It could and from time to time did cause serious harmonics and or transmit noise. GE fixed that problem with the Master II. The only other problem I know of was with the mobile power supply, the rectifier diodes were poor quality and they would go bad, we got to where we would just replace all of the high voltage diodes with M-2.5 Mallory replacements.
My second repeater was a UHF Master Pro, I removed the 12 volt mobile power supply and installed a 110 volt Motorola Compa Station supply (with a few modifications). I built a 10 and 12 volt regulated power supply and used the repeater controller I had built for my first repeater. By the way, my first repeater was built out of a T-44 with a AC power supply. The GE Master Pro repeater worked for years. Sort of takes you back don't it! Also, your very correct about the GE TPL radios, they stunk!

I still have SEVERAL of the late model Mastr Pro's in service as repeaters on 6 meters, 2 meters, and 440 MHz in Oregon & Washington. Their receivers hold up in the most harsh environments. I have no immediate plans of retiring my Mastr Pro repeaters. (Of course, the Micor is no slouch either - I have those on as repeaters in Iowa) Neil McKie <[EMAIL PROTECTED]> wrote: SNIP > the Mastr Pro showed the county shop guys all was not lost. > I know, I was impressed.
