[Scan-DC] Arlington Co. TRS New Talkgroups

[David Schoenberger]

While monitoring the Arlington TRS on Friday, I found some talkgroups
that are either not in the RadioReference database, or need some
clarification. Thanks in advance if anyone has more info:

33616 listed in RR DB as "Special Ops Field," but sounded like an
ambulance transport

34320 appears to be "George" Sheriff channel

34768 brief traffic monitored; not in RR DB

34832 mentioned "SOG" and "supply room"

57856 probably a Type II talkgroup, even though Block 7 is listed as
Type I. Appears to be some kind of transportation--maybe the ART
buses? Mentioned "arriving Chestnut Hill" and "Arlington Hall."

By the way, I didn't hear much traffic all day from the local
government users, who previously used Blocks 2 and 7 of the TRS.
Anybody know the story there?

Thanks,
Dave
