It's been a few years since I played with the 1520/4020 units, but if memory serves me correctly, you'll need to enter in the DTMF command to tell the internal controller to enable the pl encoder. The internal factory controller also controls the state of the tx's pl encoder. Each time the power is reset to the RP1520, you'll have to go through the procedure of entering the command. The other option is to study the schematic and permanently set the logic state between the CPU and encoder chip. Hopefully you only disconnected the "TX" side of the internal controller (ie: tx ptt and tx audio), and left the factory controller still attached, so as to decode incoming dtmf tones. Eric KE2D
