I can tell you what I've came up with on mine and it might help. I have
M120's as link transmitters, the boards are basically the same. If I turn my
power down below 8 to 10 watts it starts acting up, spurs and changing power
out each time you tx out. I keep my power set at 12 to 15 watts and seem to
do fine. I mounted it and VHF radius 100 on top of 12 amp Astron. I have 5
of these units running in repeater system. Some of them have ran as long as
8 years with out being touched. When I did have problems it was power supply
problems not radio problems. I also put 4" fan blowing across the fins.
Hope this helps. Bruce KD4BOH.
