OKC area NXDN ...

Are there any active channels? I have entered what I found at https://digitalfrequencysearch.com for Cleveland and Oklahoma Counties, but so far the only thing I am seeing 853.1375 (The City of Midwest City) light up with a RAN. Since these are entered as conventional and then set to digital only by me to prevent analog falsing, can I assume this is really a NXDN channel?

I'm sure https://digitalfrequencysearch.com makes a guess based on the licensee's emission type but is that an exact match? Or could the same emission type actually be one of several DV types? My 436HP has all the keys, so I assume it will decode whatever is appropriate.

And let me quickly add that even though BNSF and UP have updated their licenses for NXDN (which is the AAR's preferred digital solution) I don't actually expect them to start using NXDN for years.

Looks like they are just best-guesses at that site. On 461.9000 and 463.5000, both licensed to Chickasaw, I get Color Codes and slots, so pretty clearly DMR there ... TGIDs, too.

There is no way to tell besides direct monitoring. Sometimes more emission types are on a license than are actually used and sometimes they use emission types that aren't on the license. The same is true with frequencies.

I figured as much. I was really hoping that someone was going to say "yeah, listen to <some frequency>" but alas ....

I've been logging on my BCD436HP using ProScan today and 853.1375 and 806.1375 are both showing up in ProScan as "NX4" with "R 1" in the Tone column (which is a RAN, I gather). Maybe it's really a NXDN system. The signal is always there on 853.1375 so I put a negative delay on it so it would start scanning every few seconds in case that signal was real. Maybe it's a control channel? Sentinel hasn't been updated to do anything with NXDN but maybe ProScan has. I know basically nothing about NXDN ... guess I need to read up.

You might try your local county jail - I've heard they run NXDN in simplex...but I can't verify that.

On a clear night, I can hear Enid...it's a little choppy with the 536.

The Devon/Cana Gas Plant ( https://www.radioreference.com/apps/db/?sid=8591 ) comes in ok for me, but very little activity.

I drove out to the gas plant in Canadian County yesterday to see what i could find...it was a sleeper!, I guess because it was Easter. I then drove to Enid and picked up all 5 LCN's and also logged an undocumented TG which might have been PD. Its number was 31103 and also logged a RAN of 1.

We're you able to log all the LCN's for the gas plant? Also note the license actually shows 5 freqs.

From what I've found in enid 31100 is Life EMS. I'm thinking all the 311xx is releated to EMS.
The 1000x TGs are PD and animal control.

KAMO power has a large system in OK and MO that I've been trying to work on getting the LCNs correct with the licenses.

Where is the easiest place to find the frequencies that KAMO uses in and around southwest Missouri? Thank you.

Yes on the LCNs for the Gas Plant - they are submitted and available in the database (click on the site name). Listing again here, they are:
CH ID Frequency
111 451.375
139 451.725
511 461.375c
675 463.425

As for KAMO, yes - we should work on figuring out that system...it's very large. I can only hear the Shawnee site typically. I did find some new freq for that site and think I submitted them, but they aren't in the db yet. They are:

Shawnee - Site 3, RAN3
153.650 - LCN10
153.725 - LCN11
152.945 - LCN12
153.110 - LCN13

Neighbors 4 (CC10), 10 (CC40), 29 (CC125)

I am in East Norman and can probably hear this node. Will take a listen later today.

Is there any documentation on how the NXDN stuff works on the BCDx36HP? I have, through intense deduction, figured out that "NX4" is a 4800-baud transmitter and that "NX9" is a 9600-baud transmitter. Sadly, I have no idea what that means. :lol:

Unless it's changed like, today, Sentinel doesn't do anything with NXDN. I do have a license for ProScan, though, and the author has made some NXDN updates but I'm still left with not really knowing what that means.

If there aren't docs, how about a comparison to, say, a DMR system?

The only frequency that seems active is 153.6500. Progged as a conventional, I get a display that tells me Sys is 10, Site is 3, and both TG and U are 0. Icon says NX4.

So is this a control channel or something?

ProScan will let me program a system as NXDN Trunk or NXDN OFT. I see in the DB that this has 2 frequencies (though it may be behind since you have four). I'll program it as a trunked system and see what happens.

Correct that is the control channel. The System ID for KAMO is 10.

All four of those frequencies are on the license for Shawnee. I ran LCN finder for several hours a couple days ago on the Bristow site with no hits. (Actually I had one LCN found on the CC 153.260 CCID/LCN 14.)

wx5uif · Apr 5, 2018

Got these for KAMO today. I wish I would have looked at the site numbers...

Stillwater

151.535 126
151.6625 128
153.1925 129
153.35 125

(License shows these but no hits on LCN finder. 153.3275, 153.4925)

Bristow

151.4975 16
152.2850 17
153.2600 14

(License shows 154.6100, but no hits on LCN finder.)

Yes, this is a trunked system. "OFT" is short of "one frequency trunk". You could think of OFT as a conventional, where there can be different users on a single frequency. The 4800 and 9600 are just different flavors/brands sometimes of trunked systems - some having to do with the bandwidth allocated (12.5k or 6.25k). You can think of the NXDN trunked systems similar to a P25 or Connect Plus DMR system - there is a control channel, all voice channels are digital, and they are (can be) networked to other sites.

On the 536, I've been just editing the favorites list with a text editor once I get enough info to actually program the system(s). It works ok...I actually prefer the GPS input in dd.dddd vs the Sentinel dd mm ss.s and easy edit several channels quickly.

Eric Cotrell's post is helpful, though not related to Uniden's implementation:
