[App_rpt-users] RTCM CTCSS Output Tone

[Jim Duuuude]

Sorry if this information is redundant, but I havent had time to follow all the messages here..

The channel driver (chan_voter) in Asterisk is what generates the CTCSS tone for an RTCM (or Voter board),
if you use the option to feed your transmitter flat audio.

Just received my RTCM!  Whoo Hoo!  Have a question though. 
 
The PL tone output is also the transmit audio output. With my USB fob, I 
used both channels of the TX out, one for PL and one for audio. This worked 
perfectly for a Motorola Mitrek. Now I will be using a GP300 or P110 for a 
transmitter and would really like to separate the PL tone output from the audio 
output. 
 
What have others done? Will a 16 pin GM300 take PL into the microphone 
input? 
 
Or are you running the RTCM transmit audio into the flat audio input of the 
radio?  Does the radio provide deviation limiting with this setup? I don’t 
think it does. 
 
Thanks!
