[App_rpt-users] Talk-through tone....

[Ramesh Dhami (VA3UV)]

Hi Guys;

I have just updated to app_rpt v0.307 from 0.306.


My main motivator was to get rid of the darn squelch crash on my 220 
repeater!

So, I have added the following 2 COP commands to rpt.conf

882=cop,58              ; talk through tone
883=cop,59              ; normal ctcss



So the cop,58 command works great for LOCAL RF users - no more squelch 
crashes - YEH :)

However, we are not hearing remote activity (from connected links) or 
any 'commanded' telemetry (link status, etc.) - it's all there, but no 
PL is being transmitted.

What am I missing???


Here is my usbradio.conf file contents:
