Does anyone have any insight as to how the SP's on Tinker run their radio system. I hear Control simulcast on both frequencies of 406.1625 and 407.1625 but everyting else, i.e., handhelds and mobiles, is only on one freq or the other. How are the channels assigned and how do they keep traffic from both channels going on at the same time? Or do they have 2 different dispatchers in the same room, 1 on each freq, but able to monitor both channels?
