On a side note, I heard several transmissions in the clear on 171.9875 $167 last night and early this morning. Nothing distinguishable - just short comms from a YL calling for someone.

I routinely hear that freq. with mixed clear and encrypted surveillance traffic. Always following people around the Cincinnati area. It's very active. A few of the radio ID's logged: 3114049/3113004/3114000. Given the nature of the conversations I have heard I had it ID'd as DEA, but I could be wrong.

OK, that last letter is a capital I and not a lower case l (L).

The RID format I know of signifies these as FBI.

Around me it's used as an input to a Reclamation repeater.

Interesting, thanks. I'll update my files.

Yes, hard to tell sometimes on these Dang computers

$167 99.9% of the time means it is the FBI especially in VHF bands.
$156 99.9% of the time menas it is the DEA especially in UHF bands

Most of the clear traffic on 171.9875 $167 seems to be an ID followed by the time. I keep missing the first part, but its "??? 390." I think the second or third letter is "U."

I use to hear quite a bit of traffic on that frequency in the clear. All of the sudden it seems it's gone all encrypted.

Also, I am picking up 173.250 131.8 loud and clear. I'm trying to determine what it is. Hopefully a few days of recording I can help nail it down.

even with encryption you can decode radio ID's.grouping those radio IDs that pop up on the same NAC can give you an idea of what agency is keying up..

did it here in philly with our p25 federal interop channel..but usually only catch B-ATF-E teams on ops..
they have like 7 or 8 digit RIDs..

Correct, however the OP made no comments about RID's and based on that CP and I would not have questioned the comment of the ENC, however not many folks [based on postings] are into Single Freq P25 trunking and until a NAC is entered the process can provide false info, especially where a Freq is shared with different NACs in a Region

ie: 163.7000 here in New England is an ICE NAT with one NAC, but it's the RI Rptr with a different. Same with one of the CBP Air channels one NAC for that and a 2nd for the TSA Low-Power xRay/Scanners at Logan.

171.9875 $167 was just active with traffic: "KQC 390, 2215." That's the ID for the FBI Cincinnati Field Office, if I'm not mistaken.
