Did Inova change the control channel for this system? I believe that 464.825 is new control channel on this system per what I am listening to and per the license.
I will have to check on that. I will check tommorrow and report. I was using my yaesu vx6r to to verify data bursts. I think it intermittent.What color code are you getting on 464.8250? The other three frequencies on the XPT system are using color code 1, so if 464.8250 is using 1 as well, that's a good indication that it's part of the system. Also, are you hearing continuous data on the frequency, intermittent data, or voice traffic?
