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.

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! 73 Jim W7RY _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users
