Unfortunately, on our CTCSS output, there is about 0.15 Volts when no signal, and 5 when there is signal. The RTCM thinks that there is Always a signal.

Top posting is improper. Try a 10k resistor to ground on that pin. If it's TTL logic it would make that a hard 0 volts (or close enough to fool CMOS). I've had to do this before a few times.
From when I spoke to Jim about this last he was doing menu item this for version 2 of the voter, but I believe that project never got to production. I was asking for an independent setting of CTCSS level on transmit :)
If you're doing simulcast with the RTCM you'll need to sync the 9.6mhz clock in it as well, or maybe not if you don't have a ton of overlap. 73's -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
