The Motorola R-2600 Service Monitor Uses the HMN-1065D Microphone this appears to be a Small palm Mic , I would like to use the Bigger Mic , does anyone know the Wiring for the Plug I have a friend who can put a RJ-45 Plug in . I would like to use A New Mic I picked up , Mod HMN1001B Unknown if that would be compatible any info will be greatly appreciated

Thanks Don

HMN1035C is the larger version of the compact mic. The 1001 I think was used in older converta-coms and has different switching and unaware of the impedance.
