I had what I consider a reliable submission that 'somebody' is using NAC 136 on a DPS channel. After some consideration, I posted it as TABC since it was in that area. The tower (I picked) actually hosts quite a few transmitters including a DPS. The submitter said it was northern Tarrant and possibly Denton County.
The problem I have is that DPS has plenty of channels on 159.21 and doesn't need another NAC on that channel. We also have other reports of non-Highway Patrol state law enforcement units using 159.21 with a different NACs and some even using DPS NACs but using TG = 2 rather than 1.
I'm open to ideas but listed it under TABC as the NAC best matched their old PL. If we could get more ears on the freq and let me know what's actually going on there then we can nail down who's really using it.
At least y'all are awake and paying attention
Thanks,
Russell
