CDM1550 LOW TX power

Post by foothillradio »

HI All,

I have a few CDM1550 radios laying around that have low TX output. It's a 40 watt radio, but is only transmiting 3 watts. What causes this? Can it be fixed? How much will it cost on average? I also have a few M1225 with the same issue. Thanks

Could be a bad PA, sometimes caused by an antenna mismatch.

Hi,

Thanks for the reply. What is a PA? Could I switch it from another part mobile that I have? Is it expensive to order?

Thanks

Power amplifier... will require a full retuning of the radio after replacement... definitely NOT for the faint of heart
