FM modulator DX: You never know what you’ll hear

gpsLocal 93.3 WFLS’ HD Radio signal has been off for the past day or two, and in its absence, I have been monitoring 93.5 FM, a frequency that is usually occupied by WFLS’ IBOC interference.  As I live close to a major interstate and several main roads, I often get bits and pieces of audio from motorist-based FM modulators.  These are usually easy to spot, given the audio is often much quieter than a normal FM broadcast.

At 4:37 PM, I picked up something quite intriguing: a turn-by-turn navigation, presumably from a nearby motorists’ cell phone hooked up to an FM modulator on 93.5 FM.

Based on the mileage noted in the clip, the car must’ve been up to 2 miles away from my radios.  Pretty impressive.
