I'm monitoring a NXDN trunk system which is part of a network in eastern MA. One site seems to operating as a single frequency trunk as the control channel data is also a voice channel.
Has anyone else seen that sort of activity?
Yes - there is a site on a system in Maryland where when I last looked, only the control channel frequency was active and when the only user talked, they took over that frequency. The CC returned when they were done talking.
Not the same thing but I've monitored another system that used the control channel frequency as a voice overflow when all other frequencies on the system were in use.
