• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

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.

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

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...
ICE is becon or voted here then

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.

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

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.

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
