170.1000R $023 ICE in Indianapolis

170.7500R $293 - USM Court Securiry Officers [Federal Court House]
There are 10+Possible Repeater Pairs, only by finding the input
can we determine CSO-01 thru CSO-10 for the channel #/Name

In metro Indy... 170.1000 NAC 023... And 170.7500 NAC 293.

Ty. Is it common for conventional P25 to show dat and lnk like a TRS does?

 

[ecps92]

I have seen it, Common ? Good question.

Sometimes it is only when the Repeater is beaconing or could be part of a Vote-Scan network
CSO are conventional and not voted. Single site repeater inside the court house

ICE is becon or voted here then

 

[ecps92]

Interesting... as that is the only Report freq, I was going with a stand-alone Conventional.
When you hear it beacon, it is generally users turning on a radio, see if you find other beacons on other freqs at the same time.

All my other ICE notes in your area were the NAT TACS and Air Ops..
happy hunting...

It's so far only showing data and one voice hit fully E on that voice hit

 

[DaveNF2G]

Conventional roaming?

 

[INDY72]

Its a series of repeaters that are linked, using a voting system. And to add to the fun, just as with analog set ups like this, there are multiple input frequencies for each repeater with different NAC's depending on location/division, etc... The thing with Fed stuff is that unlike with "Civilian" stuff that has a nifty FCC license open to the public to view showing ALL freqs associated with each repeater location,.... NTIA stuff is under lock and key. (Except for the NFIOG stuff)... SO you have a much wider range of freqs to search through to nail down the inputs, instead of just a few freqs to put in a special side scan list.

 

[ecps92]

Now you have me wondering, if a single Repeater can be enabled for Vote-Scan, which might [hey ChrisP] explain some non-linked repeaters beaconing, just like Vote-Scan....hmmmm

It's so far only showing data and one voice hit fully E on that voice hit

 

[ecps92]

My experience with the Vote-Scan is [YMMV]
Multiple Repeaters with the same NAC output
One input for a wide-area [FBI RA as an example] with a single NAC for the Wide-Area linked Net

There have also been found, the above, but the ability to use a different NAC for single-site Operations, not Linked to the Wide-Area.

As to the FED, and some are low power sites, to cover a unique area, then others with the high power covering a large area...

Well we now have an active FBI net that was originally thought just a Chicago ops one that is also local Indy. Will have to dig to find the input here. But yes almost all FBI P25 is same NAC output. Also along the Gulf Coast FBI and I think DEA nets are all linked now? And then you have NPS for BRP and NTP... It can get interesting indeed figure out now lol.

 

[ecps92]

I've found [probably posted/mentioned before] that [atleast here in New England] the Repeaters are Clustered / Zoned by Resident Agencies, outside of Zone A, which is usually the Field Office channels

FBI and DEA are two separate wide area repeater nets on the Florida Gulf Coast. The US Marshals have started using the FBI wide area net. Both nets cover from Pensacola to Jacksonville. Wasted tax dollars on two separate wide area Motorola systems that are only used a hand-full of times during the year. The National Park Service at the Gulf Island National Seashore installed a wide area standalone P25 repeater on 166.300/172.525 a few years back. They never use it. NPS Law Enforcement finally gave the APX6000 portable radios to the Life Guards to use. I also have all the FBI and DEA frequencies if you want them, but there isn't much radio traffic. 99% encrypted except for Jacksonville FBI giving their callsign.

If you don’t mind Can you please message me that list of FBI frequencies I would like to see what I don’t have in my list not hearing much in central Florida

I was in Midtown Atlanta today and picked up 169.55 NFM unknown users talking I didn't catch the NAC code or the radio user id number when I was scanning in search mode for Federal VHF.

Probably CBP/HSI.

In Petersburg over the weekend and heard what sounded like a CC on 407.700 but couldn't get Pro96Comm or Unitrunker to pick it up.

Not FCC Petersburg, otherwise have no clue. Any guesses?

 

[ScubaJungle]

This is my list for the week. I dont know what any of them are right now, besides some possibilities:

Tam.pa Area

170.3375​	NAC100 - ENC
169.9​	NAC303 - ENC
410.8​	NAC201
164.7​	analog
418.3375​	analog
167.6875​	NAC167 - ENC

 

[RaleighGuy]

@ScubaJungle 410.8 NAC 210 usually encrypted is Federal Protective Service. 169.9 NAC 303 typically DHS/ICE.

Don't forget to check the wiki for NACS Federal NAC Codes - The RadioReference Wiki

Thanks, I was looking for that list and couldn't find it.
