Knox County school Bus Contractors have been tranistioning to DMR over the past year. And I was wondering if anybody's knows the frequencies or system they use? Lately I have been ridding the bus to and from track/cross country events. The radios on these buses are not analog like the ones I already found and submitted to the database. It seems to have great coverage whatever system they are using The signal picked up all the way to a high school near Johnson city to down toward Chattanooga had full bars in middle of downtown knoxville near the Worlds Fair Park where my school is. I have been wanting to upgrade DMR on my scanner but I was unsure if the new frieqeincies where scrambled like the bid for the radios said. I just don't want to waste money if I can't monitor them any help would be appreciated I assume they rent the system. Repeater possibly on green top? Also I have noticed a lot of school use the the frequencies with the license of WQSH790 to communicate simplex around knox with Vertex Radios that the school system leases to schools.
