unknown frequency

Was on my SDR today and I came across a weak DMR transmission at 453.801-ish. The signal became stronger as the afternoon progressed. It appears to be a school bus radio system. Checking through the FCC I found no licenses for a school bus company. I can upload some audio recordings if needed...
