Anyone have any idea who would use 163.700 in the Big Bend area? I was thinking it might be border patrol, but I don't know. They have a repeater further east (between Ozona and Del Rio) that is P25 encrypted. I heard this 163.700 today very weakly from north of Ft. Stockton. It was analog encrypted, so I have no way to listen to figure out who it is. Any other guesses?? Under the RRDB, the Big Bend area BP doesn't use these freqs.
