Listening in Dallas. It's hard to describe the sound. At first, I thought maybe I was off 5 or 10 kHz so I put it in a ham radio VFO. Tuning around, that doesn't seem to be the case as the audio sounds like crap no matter where I go. When they key up, the first syllable or two is intelligible then it all goes to garbage. I can still make out some words though so I'm doubting it's encryption.
