It's a Nexedge wide band Control Channel

I hear it around Comal County and San Marcos TX.
Also it is always turning on and off.

Based on the sound sample, frequency, location reported and FCC licenses I'm only guessing but it is pobably a site on this system that hasn't been identified and added to the database:
S & P Communications - NEXEDGE Trunking System, San Antonio, Texas - Scanner Frequencies
