Ok, perhaps I'm just crazy... but I bought an MTS 2000 off of ebay awhile back, and one of the frequencies preprogrammed in it says "Fed Channel". I have been getting traffic locally here in Columbus on it, but since I don't have the software for the radio yet, I have no idea what the frequency is. I know its not DCFS, or Rickenbacker. It sounds kind of digital, has a bit of a worrble to it. They seem to check in on the hour, with unit numbers like G501C. They also refer to dispatch as the "Mega Center" . Anybody have a clue as to what this may be.
