For the past several weeks I have been receiving Dallas Fire Dispatch (460.575) on some of the Dallas Police Frequencies (SE Patrol 460.5, CID/Gangs 460.475 and a few others) using a SDS100. It happens when both channels are active at the same time - I can hear both channels. It doesn’t help to avoid Fire Dispatch or use ATT or IFX on Fire Dispatch. Anyone else run across this before? Any suggestions? I’ve been scanning for years and this has never happened before.
