OK GE Mastr II experts, I have a question for you. Our club has been the benefactor of a local law enforcement agency's upgrade. We have acquired a VHF (155 mHz) Mastr II base station with 3 solid state PAs that total a rated output power of 225 watts. It appears to have a single PA power split into two outputs. each driving a second PA that is then summed back into a single output. I know the cable lengths of the splitters and combiners are critical. Also understood is the importance of cooling. What I am asking the experts on the list is: Is this a reasonable project to undertake converting to 2 meters (TX 145.XXX)? Obviously the tuning instructions will need to be followed precisely. This station has been in reliable service to the original owner for years. We are wondering about the reliability post conversion. If we do the conversion we would clean the old heatsink compound, replace it, and re-torque the transistor mounting screws, and change the appropriate cable lengths.
Your thoughts appreciated.. Bill, N9SII
