Been watching a feed on the u tube and the host is playing scanner traffic. Non stop the police have been saying stuff about illegal transmissions on the police frequencies. Was watching and you can hear people playing bubble sounds and goofy sounds over the police bands whichever the host is monitoring. The police have mdc identifiers and the sounds are coming over as normal radio traffic carrier. Sometimes over talking units with dispatch having them change channels and a dispatcher saying just stay on 1 they keep switching when we do anyway.
