Hello, our repeater is in "carrier squelch"-mode. Since there is much traffic on our repeater we are used to use different subtones for different user groups just for the initial call to request a group member to continue the qso without subtone (so nobody else in the group will be disturbed). Unfortunately this seems to be impossible. We tried these configurations in usbradio.conf: #1 (we tried "0" in rxctcssfreqs/txctcssfreqs in CTCSS dsp-mode) hdwtype=0 ;txctcssdefault=71.9 rxctcssfreqs=0,67.0,71.9,74.4,77.0,79.7,82.5,85.4,88.5,91.5,94.8,97.4,100.0, 103.5,107.2,110.9,114.8,118.8,123.0,127.3,131.8,136.5,141.3,146.2,151.4,156. 7,162.2,167.9,173.8,179.9,186.2,192.8,203.5,210.7,218.1,225.7,233.6,241.8,25 0.3 txctcssfreqs=0,67.0,71.9,74.4,77.0,79.7,82.5,85.4,88.5,91.5,94.8,97.4,100.0, 103.5,107.2,110.9,114.8,118.8,123.0,127.3,131.8,136.5,141.3,146.2,151.4,156. 7,162.2,167.9,173.8,179.9,186.2,192.8,203.5,210.7,218.1,225.7,233.6,241.8,25 0.3 carrierfrom=dsp ctcssfrom=dsp rxdemod=flat txprelim=yes #2 (we tried to disable CTCSS) hdwtype=0 carrierfrom=dsp ctcssfrom=no rxdemod=flat txprelim=yes Is there a way to pass CTCSS tones through the repeater in "carrier squelch"-mode ? I don't care whether it will be decoded/encoded by the software or just passed through the repeater (0-300 Hz passthrough). Currently passthrough of 0-300 Hz seems to be blocked by the software.
