170.3375 MHz in Dallas - TSA?

I have received some reports of a new P-25 digital channel being heard in the Dallas/Ft. Worth Metroplex.

Reports are that 170.3375 MHz, NAC001 has been heard with clear traffic that seems to make references to possible TSA operations at DFW Airport in Grapevine.

This frequency does not appear in the previously known TSA frequency assignments, however, DFW Airport had always had some non-standard TSA radio operations. 169.1625 MHz and 169.1875 MHz have previously reported as being used but the TSA at DFW. Apparently they were concerned about TSA frequencies used at Dallas Love Field would interfere with operations at DFW.
