462.675 (CH 20) Data/Telemetry



I was bored on the way home from work (scanner was slow), so I flipped over to GMRS. On channel 20, I kept hearing a approximately 3s burst come across the radio: https://drive.google.com/file/d/1zzv_86znSQPPI0RYIFJiZ7p20m9VUyHM/view?usp=sharing


This repeated every minute for the 10+ minutes I had left to get home, so I recorded it.


I jumped on the FCC to do a search for this frequency, and got zero results with location and radius of 50 miles. Any idea what it is?
