Hi everyone. I am needing the pin out for the 44pin accessory port on the back of the radio? I would really appreciate the help in finding this out so I can interface to the following:
1) filtered audio (fixed level, hopefully in the range of 300mVpp to 600mVpp... usually a typical range for filtered audio... from my personal experiences)
2) MIC audio
3) PTT
4) finally, the return signal pins for both the audio and PTT (NOTE: I know that some radios have dedicated return signal pins for analog and digital signals)
Again, all the above is for the 44pin accessory port on the back of the radio. Thank you very much for helping.
