[Scan-DC] Arlington County encrypted TGID 115?

[Andrew Clegg]

Hi all,

Arlington County's P25 system has a TGID of 115 that's encrypted.  That ID is not listed in Radio Reference. Anyone know what it's used for? Only one unit ID ever shows up (3134800), although perhaps that's an artifact of an encrypted channel? The TGID is fairly active at the moment. I'm seeing it on the trunk system's output frequencies via my Home Patrol 1 "Current Activity" utility, and simultaneously on the input frequencies via my Icom 8600.
