Ubbe, do you know of any NXDN user in Sweden?
I only listen in Stockholm and the Saab-Scania plant in Södertälje has one channel that are encrypted and there are IDAS that are some sort of NXDN variation that are used for some events like Stockholm Marathon that are encrypted or cannot be decoded in NXDN mode. It's also some sort of conference facility that use NXDN here before I could decode it that nowadays haven't been heard. It's a satellite channel in the 250MHz range that sometimes use NXDN that can be decoded but are only some chit-chat conversations by unauthorized users.

It's a very specific sound to NXDN modulation, it's very soft almost like a whisper and not as harsh sounding as DMR, so is very easy to identify.
Just search the frequency ranges and record everything that opens squelch and then listen to it. But as DMR seems to be a cheaper and easier system to use it probably isn't many NXDN radios sold. I haven't studied NXDN's technology so can't say if it has any advantages over DMR to make someone want to use it.

I am still confused. It says DMR NXDN digital capable ( with an Asterisk) but i keep seeing that the DMR and NXDN are conventional. What is it and what does the asterisk mean?

Could also be dPMR. The problem with dPMR is the codec, which could be AMBE2+, RALCWI or some CCR homebrew stuff. dPMR does not strictly define the exact codec that has to be used.


dPMR with AMBE2+ support would be nice.

The trx-1 does not decode dPMR tier 1 for example.

Thanks for your answer.
Can't remember if I have heard anything like you describe, but I'll check the frequencies if I hear something like that.

Maybe NXDN is too expensive for smaller users and they choose DMR instead.

Conventional means "not trunked". Digital modes (including P25, DMR, and NXDN) *can* be trunked, but they can be conventional too. That just means a digital format is being used on a single frequency.

Everything we have seen and heard says that the two new scanners will be able to decode DMR and NDXN, but they will not trunk-track.

Ok so they are digital but no trunking involved. Thanks.

My third cent (since I already used my first two):

I think what many are overlooking when they complain about the features of these new scanners is that we ALL, as scanning enthusiasts, should be very excited that Uniden is actually introducing NEW scanners in 2023 (or 2024). Obviously the company feels it's a good business decision to do so, and THAT is something to be happy about whether these new models are something we intend to purchase or not.

If Universal Radio was still in business I'm sure they would already have all of the details/specs of the brand-new Uniden BCD260DN posted on their website and would be taking pre-orders with FREE shipping included! They were certainly on top of their game when it came to the release of any new models of radios/scanners or other related equipment.

If you recall, back in early 2018 Universal Radio let the cat out of the bag prematurely regarding the upcoming release of the SDS100 handheld. Uniden "blew a gasket" when they found out about it but there was nothing they could do because the horse had already left the barn! LOL
This thing looks a lot like my old BCT15 on the front, including the 'tracker' footprint in the upper right.

Yes, 'conventional' does not mean 'analog'...though that is a point of confusion I've seen in various places here or in Facebook groups over the years. There is 'convention' and there is 'trunking'.

you gave me an idea, however, wouldn't analog means like no digital screen and isn't conventional?

off to check my idea, lol

I am a huge fan of ProScan, but I'm not sure it's a matter of "doesn't trust Bob". If I am not mistaken, these new scanners will be of the "banks of channels" variety like the BC125AT and BC75XLT, right? ProScan doesn't support those models, but Butel does. I guess if I had been Uniden, I would have reached out to Bob and told him, "Hey we're going to release these new models but our guess is you won't want to support them in ProScan" but I'm not Uniden. :)

Good catch!
I'd definitely buy a BCD260DN if it could handle linear simulcast modulation transmissions, even if it can't track trunked radio systems.

That's probably 'way too much to expect, but what the heck . . . it's worth dreaming about.
