Search for ID/TGID in digital frequencies

[jre]

My work has the Kenwood Nexgen radio's. They are using 464.1625 and 464.2875 both on direct (T/A no repeater) frequencies that are digital. I found out by the servicing radio company that we are programmed on the P25 programming but wouldn't provide other information.

I have the frequencies programmed into the scanner a few ways but I can't hear them. Is there a way to program the scanner with the above frequencies using P25 and search for the ID/TGID needed to hear them ?

The frequency is not scrambled just digital instead of analog.

What city, county, or agency? Link to it in the database?

While the radio service said it was digital, is it possible they are actually NXDN, not P25? If P25, Phase I or Phase II, your 536HP would be able to monitor them, unless encrypted. But if NXDN, currently the only scanners that receive that mode are Whstler's TRX-1 & TRX-2.

I Googled "Kenwood Nexgen" and came up with nothing matching that term. There is Kenwood Nexedge: Land Mobile Radio - KENWOOD USA

The "Nexedge" radios are capable of several different digital protocols, including the NXDN mentioned above. If your company has selected the NXDN, then as noted above, your 536 isn't capable of decoding that format. You may hear "noise" but nothing intelligible.

I see references to NextGen all the time and there doesn't seem to be anything definitive about that label/description.

There are several options:

- do a custom search of/around that frequency and see what you receive
- program a P25 One Channel system with those frequencies


Easiest is probably: program the frequencies as conventional/analog and listen... what does it sound like?

Digital*Modes*Samples

You can also post a recording and we can probably tell you based on the sound.

EDIT: Might this be in Windsor Locks? I see a license for that area which is NXDN voice and data....

No TGIDs on conventional channels and I thought I read that the UIDs won't display either.

Seems we need to determine which digital mode as a first step...

I made an error the radio is Kenwood Nexedge not (nexgen). I do not hear anything at all on the two frequencies 464.1625 & 464.2875 on convention or analog. but radio service told me it's programmed for P25 and it's digital (not scrambled or analog).

I won't post user name, state, county information until I get all of the information to listen to these channels.

As in my original question. Can the BCD536hp scan the above frequencies for the P25 ID's or TGID's so that I will get the audio ? and how is it done. Please

Something isn't set right. Turn on Close Call and key up the radio and see what the scanner does. If you aren't hearing anything, you likely have something programmed wrong. P25 is the x36 line's bread and butter.

We can't help you further unless you indicate which department you're trying to monitor. It's not classified info.

Hmmm.... P25? No. Not if it's a Nexedge radio.

As was stated previously, it sounds like you have a NXDN radio and not a P25 radio. No Uniden scanner handles NXDN. Since it does not decode NXDN, it won't tell you anything about the call metadata (talkgroup or radio IDs) and the audio will just sound like digital noise.

EDIT: I could be wrong - what is the model number on the radio?

Can you just post the model of the Kenwood please and help us all out?

OK - back to the original question....

I have the frequencies programmed into the scanner a few ways but I can't hear them. Is there a way to program the scanner with the above frequencies using P25 and search for the ID/TGID needed to hear them ?

I just did simple programming of a known P25 (trunked Phase 1) voice frequency on a 536.... All I did was

• Press the CHANNEL button.
  
• Enter the frequency and press Enter (save into Quick Save). Note that I didn't set the modulation type or any identifiers (talkgroup, radio, etc.)
  
• Backed out using the menu key until I was monitoring that single frequency I entered.

I am listening to P25 conversations.

Now, this is a repeater frequency and I can hear it at fairly great distances. If your frequencies are direct/non-repeater, you should still be able to hear them (using this and other already posted methods) -- you just need to be VERY close.

You should not need the talkgroup or radio IDs.

If you are not close enough, you are not likely to hear a non-repeater/direct transmission.

If the signal is other than P25 Phase 1, there would be other things to consider.

See: NEXEDGE - The RadioReference Wiki

Sometimes folks can be pretty cavalier when using terms like "P25", "Digital", "NXDN" and so on. These terms have been known to be interchanged though there are differences/nuances/etc.

If it was me, I'd program both frequencies as conventional channels in a conventional system and set the Audio Type to "All" and do some listening. While Talkgroup IDs are associated with trunked systems, you can program trunked system frequencies as conventional. You may not be following trunked groups, but you'll at least hear something to know you are in the right ballpark. (Of course if they are using NXDN, all bets are off because Uniden's won't decode NXDN,)

OP. If you have a radio that says NexEdge on the side of it it is Kenwood. With very very few exceptions a radio that says NexEdge on it will not decode any other digital format other than NXDN. So if your Kenwood radios are working in a digital mode then it will have to be NXDN unless you have NX7xx or 8xx mobile that has been Factory flashed for p25 operation or you have NX5xxx series with P25 option.

So again, tell us what you have that works on this system? Sure would save a whole bunch of guessing from all these people trying to figure out what you got.
