I believe this system is a DMR system simply based on the Kenwood NX-3820 low power base
station, which I looked up and the display indicates a digital system however, when programming the frequencies and I do hear talk between units, but not necessarily on all frequencies and I get pretty simple displays no color codes or anything like that that I believe are common to DMR systems.IMG_3189.png

As pointed out earlier, by @ScanRite , this license is expired and a search of the FCC database does not show a new license, so apparently they aren't worried about the FCC renewals or rules. However, the original license was analog, but they could have switched to DMR. It is hard to say unless we are there to listen. Keep in mind UHF is a designation for frequency range not mode, UHF can be a number of modes such as P25, DMR, NXDN, or analog, among others, but it is still UHF.

Looking at the emission designator it shows analog. See red box.

Thanks, did see the follow up on the expired license.

The system is up and running fine, obviously no concern for any FCC reaction, most likely a contracted communications service company provides the equipment, you would think if that was the case they would insure an updated license renewal. Was just curious, not like it’s a public safety entity.

Yup, but in 2023 when that was pointed out to him by @PDXh0b0 , it was only expired for 8. As seen here, Salem business freq needed

I did not locate those freqs on another license so its pretty clear they are having at it unlicensed.

Since you have been at this for 2 years, options are,

Get a dongle and Dsdplus.
Ask someone in charge at that place what's up.
Call these guys and ask them what's up.

Not much you can do with an expired license and a Uniden.

anywhere
The SDS-100 scanner will tell you if its DMR or NXDN. Its showing you NXDN. NXDN will always show you a RAN RX code. And it looks likes a conventional repeater, but it could be trunked ?

Ok, So I would just enter the high power ( looks like 20 watts) repeater frequencies above to be able to hear all the traffic, seems I’m missing some traffic.

Thanks so much, This is the first NXDN system I’ve listens to.
