I imported a car from Japan and it would get audio from TV stations as the radio went down to lower frequencies =)

Before the North American conversion to a digital only TV broadcasts, the audio for all analog channel 6 television stations in the United States could be picked up on 87.7 FM

Some channel 6 stations have expressed interest in/have implemented also broadcasting the sound for their broadcasts back on radio again after moving solely to digital broadcasts.
