Kevin - Thanks for the clarification. I have one of those 1/4 KW VHF MICOR Repeaters in my garage, and wish I could get it to move down to 2-Meters. We have a local government agency that has one on 151 MHz, the sticker (the Motorola sticker that says ___ ua = ___ watts) on the inside of the cabinet says that it's doing 430 watts output! We always thought that one would be fun to move to 2-Meters on a simplex channel, but moving it there would be nearly impossible. LJ

Larry - I didn't. The 250 watts is produced by a GE MASTR Pro/II 4EF5A1 capable of 330 watts continuous. The MICOR high-band tube amplifier, IMHO, is junk compared to the GE 4CX250R based VHF power amplifier. The 4EF5A1 is designed to operate from 144 to 174 MHz. without modification. Obtaining proper drive for it was the fun part.
