What is a USM Radio? DSDPlus log excerpt, someone may understand it, huh?

Sync:+P25p1 NAC:167 TDU
Sync:+P25p1 NAC:167 PDU CONF DATA SAP=32 MFID=90 Blocks=1 LogicalLinkID=8802305 [[30.50472,-83.88321]] Aff'd TG=1
0 1EE 41865001 00000000 0A61C002 BCB55607 A.P......a....V.
Sync:+P25p1 NAC:167 TDU

USM = US Marshals Service
Generally their RIDs are 8xxxxxx Series and FBI is 3xxxxxx Series
where
304xxxx = Atlanta Field Office
306xxxx = Birmingham Field Office
322xxxx = Jacksonville Field Office

aff'd = indicates the users radio affliliated to that TG of 1 (common TG)

...No traffic monitored. It sends out a digital station id every 2 min. ...

Not really an ID. But it does send things like the NAC code.

Hey b mendez the only thing I have seen in the clear is:
freq P25 167.7125
NAC:167 pretty sure this is a FBI number, may be wrong tho
RID=3221135
TG=1
2 women talking about radio checks, like I have said I can't really understand digital
conversations. Lots of freqs being used but this is the only one not encrypted that I
have seen.

322xxxx would be a Florida Radio ID (RID) out of the Jacksonville Field Office
and the 7125 Repeater is likely somewhere in the Pan Handle

Thank you guess I really appreciate it

Well I am 20 miles from the Florida pan handle state line, so I guess that sounds right, thanks.
There is 3 or 4 freqs that hit at the same time, 167.7125 just happens to be the strongest. May be
skip, I'll sit a little more on these.

Typical FBI nets are
a. One Common input
b. Multiple Repeaters spread across the RA Territory anywhere from 3-12+ sites)

which ones do you hear key up at the same time for the Pan Handle ?

Working on that Bill, Perry Mason had a problem I couldn't get away from. Anyway it looks like
there are at least 3 different sets of freqs that key up at the same time. Gonna do some screen
snips and let yall see. Also try to determine the freqs for each group. A couple are so strong that
it wipes out the whole 10 meg display when they hit every 2 min. May take a while, Matlock is on
now, LOL!

inputs are generally (there are some exceptions) down in the 162-165 region

6075 and 6325 are suspect as the band would be

167.6000
167.6125
167.6250
167.6375
167.6500
167.6625

Seeing some P25 "data bursts" on 168.975 NAC330 in Auburn, AL. The FBI seems like a possible candidate based on some forum searches, but I did not see this particular frequency mentioned for this area.
