NYC DOITT system Control Channel

[DOPPLERBOB]

I got back from vacation and all of a sudden I do not receive the control channel for the DOITT system on any of the 15 frequencies. It was on 860.9375 for the longest time. As I manually step through the 15 channels, I can receive DOITT transmissions loud and clear, so it doesn't seem to be an issue with reception. The Pro-96 will also decode the talkgroup if you are manually stopped on a frequency and it is set in the MO (motorola) mode. The talkgroups are coming up on the display and everything, but no contorl channel data can be heard at my location on any of the 15 frequencies (except I get control channels from other systems on a couple of the freqs, but they do not belong to the DOITT system).
Is anyone receiving the Control Channel data now?

I had a similar problem last week. I normally scan in control channel only mode, and it seems they changed the usual control channel. I switched to scanning all of the channels, and programmed them in. Now I'm receiving DoITT again.

Hmmm. But I tried all of the 15 freqs of the system, and cannot receive it on any of them. But I get transmissions from the units on the system loud and clear. What freq are you getting the control channel on?
Thanks, Bob

Thank you everyone for your replies. Here is what happened. As you all noticed, the control channel changed to 859.9375. That is one of the 4 freqs that is allocated to be a control channel. There are a maximum of 4 freqs that can be allocated to a Motorola trunked system. The reason why I was not hearing it was it was also the control channel for the East Hampton,NY (eastern Suffolk County) trunked system for the past few days, and I am much closer to them than I am NYC. Even with my 8 element beam pointed at NYC, the East Hampton signal out does the DOITT CC. I hope the DOITT system switches back to using the 860.9375 frequency, as it is not a part of the East Hampton system. That freq is shared with the Hartford, Ct system but they don't come in here strong enough to affect anything.
