Jim, If you are converting a carrier-squelch radio to TPL decode, you must remove the jumper that normally bypasses the PL decoder. Do you have the manual that covers your particular station?

I made the changes to the encoder board per rptr-builder. Although, I have yet to see it decoded on my service monitor with the input audio at TB1(1&3). I am learning what all the jumpers do/not do on the Micor. I get mix-up as to which tone the manual is referring to.Control tone or PL tone. Motorola Control tones are not used at this site. The Micor receiver, does decode the PL, w/ audio at the speaker, but the audio doesnt come out at TB1(4&6). Remote Control Chassis -TCN1148A/TCN1223A Stn control - TLN4635B Line driver - TLN4668B Sq. gate - TLN4662A Time out timer - TLN4636A Any input which will make this simpler ? Thanks for your input. 73's, Jim Kh6jkg.
