I'm using an RTCM for a half-duplex link, adding Allstar to an existing repeater remotely. (We don't have Internet at the repeater site yet, but eventually the plan is to have the link at the repeater site in full-duplex mode.) I'm trying to deduce the canon method to program the radio. The repeater only transmits PL when the receiver is active, so with CTCSS on the link receiver I don't have to worry about courtesy tones or IDer getting through the link. I have the RTCM set for external CTCSS. What I think I need is the link radio programmed for TX 147.90 no PL RX 147.30 88.5 Hz CTCSS Then add txctcss in chan_voter, so that the link only transmits PL when there is audio on the link. I don't want the link IDer going through the repeater. As far as I can tell, there's no CTCSS DSP in the RTCM or chan_voter, so I need to use the radio's CTCSS. Is this correct? Tom KD7LXL
