Hi,
I added an external controller to our club's repeater. I used the
instructions found on the RB website to disable the internal controller.
What that paper does not cover is how to re activate the TX PL tone. Does
anyone happen to know how to get that working again ?
TIA

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.
