Greetings. I have 2 GM300s that both have the same problem. After they warm up they get distorted and seem to drift off frequency on both transmit and receive. Any ideas? Thanks in advance for any advice. Bill

Also, if the radio was force fed a code plug from another radio, the compensation setttings for the reference oscilator will be incorrect and it WILL drift with tempature. You have to go thru the RF and logic board replacement procedures in the RSS. Specifically the crystal perimitters and the voltage reading that are entered into the RSS.

The board interconnect pins may need cleaning.
