Did you check the rest of the frequencies for a control channel? It's rare, but sometimes they do roll.

DOITT 700

I programmed all the frequencies as a "conventional system" and I am getting lots of traffic on all the frequencies, but none are giving me control channel static.
The control channel programmed in as a conventional channel is locking squelch but no audio at all??

Are you using a Uniden scanner? If so, most models automatically mute the control channel audio if programmed conventionally. If you see DAT flashing on a particular frequency, then that's the control channel.

Yes it is a uniden bcd325p2 I have 3 or 4 other NYC trunked systems in my scanner and if I hold on their control channels I hear the control channel noise on all of them.
Besides that the DOITT 700 has been trunking fine until today. Something happened to their control channel
Their units are communicating normally but my scanner can no longer trunk the system.

Could be an issue with simulcast distortion, perhaps due to atmospheric conditions. See if moving the scanner around helps any, as dumb as that sounds.

I literally just checked it 10 minutes ago. Locked onto 774.34375 immediately and was monitoring the system just fine.
