Federal Radio IDs

[west-pac]

320xxxx is the Indianapolis Field Office
Covering the counties of Boone, Clinton, Hamilton, Hancock, Hendricks, Howard, Johnson, Marion, Morgan, Shelby, and Tipton

As to where this repeater is, I would suggest more listening and see if they slip up on the channnel name/location
or you can match cross-streets from a Surv.

Hint/Note - don't expect a lot of Federal to actually be in the RRDB

There was no radio traffic. This is a beacon at specific times of the day.

This FBI list is quite detailed, so I presume it was accurate at one time. U.S. Federal Government (Indiana) Scanner Frequencies and Radio Frequency Reference

So, there is only 1 "FBI Field Office" in Indiana, in Indianapolis; but apparently there are ~15 additional satellite FBI offices around Indiana.

167.4375 and 167.6625 simulcast the same beacon, with the same RID, at the same time intervals. Neither of these freqs are listed as the closest FBI repeaters to me.

Also, in Indiana, Federal agencies use the statewide P25 system.

Field Offices aka FO would be the Regional HQ
Resident Agencies aka RA would be the substations under that HQ

Odd on the Beacon to show a RID - never experienced that in my home region

IF the same ID was talking at the same time on multiple repeaters, then it is a Wide-Area or Vote-Scan "Net"
but the beacon of the RID does have me baffled

I would say. based on a recent visit to Indiana, that "SOME" Federal agencies have access to the statewide P25
as I did find users on their own NTIA Federal allocations.

Altho yes quite detailed, much out of date as the Bureau went P25 long ago and I see PL's still listed

Keep in mind, the Networks are always in a state of change, depending on what coverage they need
Recently we [Boston area] have found 3 new Repeaters in use.

Two part of the Wide-Area/Vote Scan for an RA
the other seems to be "Gang" only related

Fwiw, 167.6625 is still Fort Wayne, IN. I happened to be in Fort Wayne at the correct time for the automated beacon; received it full-scale on a handheld.

Now I need to program the VA stuff in, and see if I receive any of that stuff.

How about getting the DB updated, as it still shows PL not P25 , as you actually confirm them to now be P25

407.775 NAC:482 TG:1 P25E RIDs:40208, 8322xxx, 8321xxx, received in East Central Indiana. I saw this freq and NAC listed in a NYC post from earlier this year. Possible USPS? I only received this for about 10 minutes during twilight this evening. The signal is completely gone now.

Pretty much Day-time Ops Only or during a Surv event
US Postal Inspectors (aka PIS) - 95.999% ENC [been so long since I heard clear, might need to up that to 99.989%)

Postal Service / Postal Inspection Service Frequencies

Here is a list of confirmed frequency allocations available to the US Postal Service: 162.1500 162.2250 162.2500 162.5875 162....

I did a little more digging, and the closest PIS facilities, to me, are Indianapolis, Cincinnati, and Detroit. Of those three, I believe, Detroit had that freq listed. Today I left DSD+ sitting on 407.725 to see if I receive any activity there. That seems to be another common PIS freq.

I can tell you that a lot of Feds from various agencies are using State, County or Regional trunked systems owned by all three of the above as their PRIMARY comms. Most of it is due to interoperability and even more so, coverage. Most fed systems barely have street coverage in a lot of their AORs.

As far as identifying UIDs on these systems, it all depends on how the system admin sets it up. I've seen certain agencies get their own "block" of IDs. I've also seen some get their own talkgroup, and its strapped to ENC. But I can also tell you I know of a certain three-letter agency that uses a County system full-time and the Sheriff radio shop just gave them the next sequential number in line. Same when they add new radios. They also don't have their own dedicated talkgroup, just use one of the available Sheriff's tacs as their primary.

As far as identifying their UIDs on their conventional P25 fed repeaters, good luck....that radio is literally on their desk collecting dust, buried in a bag in their lockbox in their g-ride (most don't even have mobiles anymore due to the switch the trunked outside owned systems) and they haven't been rekeyed in months via OTAR.

Those would be the Hubs, but (IMHO) there are multiple repeaters spread across the Operational area

Keep in mind, not all has been reported/shared with the RRDB (Federally)

And also Zello on their phones...

170.725 and 170.9125 P25E TG:1 $167 RID: 3209xxx simulcast beacon north east-central Indiana.

I've learned that the following freqs all beacon at the same times everyday, with the same RID:

167.4375
167.6625
170.725
170.9125

The 170mhz freqs were received better at my location in the morning, possibly due to some enhancements, or a quieter RF environment. 🤷‍♂️

 

[ecps92]

Could also be the 167's are farther away

The 170's get weaker during the daylight. They are likely further away from me.

I know where one of the 167's are. The 170's I do not know where they are.

 

[ecps92]

Which RA do you feel they are attached to ?
my experience, (varies in each FO tho) is that each RA has it's own Zone and set of VS Repeaters
Once you know which RA, then narrowing down a site get's easier or atleast geographically smaller
