Brian, I just checked my UHF Micor manual, and it shows that TLN4926A Power Control Board is used in both the 2/12 W and the 75 W stations. That suggests that all of the scaling is done in the antenna network, which is different for the various power levels. You should be able to use any PA you want, because the appropriate power control functions are integral.
In the specific instance of converting a 2W amp into a 12W amp by removing the power attenuator, you need to add the resistor and the thermistor in order to properly protect and control the PA. 73, Eric Lemmon WB6FLY Brian Williams wrote: > > What alterations need to be done in the sensing circuits, What I have done > exactly was convert these 2-watt repeaters to 75 watt with a high power PA I > had.
