another thing i am noticing especially with some systems where i am at in Portland, OR currently, some it looks like some SMR's are licensing up blocks of bandwidth, and these are not even listed in the ULS properly and may not be, keep this in mind

Not sure if it was this thread or another one where someone was saying you can't do the control channel only scanning.
I have a system around me here where there's only 1 frequency assigned to the local tower. Now granted it's definitely not busy because today was the first day I actually heard something on it since doing the NXDN upgrade. But I did hear comms on the 1 and only frequency assigned which is also the control channel as well.

Just for clarification - that's not "control channel only" scanning. I'm not 100% certain but I suspect the radio still requires the LCN to be known/programmed even for a 1 frequency site. I have a similar system/site in my area.
"Control channel only" would mean that you could program only a control channel frequency and the radio would just "figure out" all of the voice frequencies all on it's own - somewhat akin to P25. It doesn't do that.
Yes. I do have the channel number for the only frequency for this particular site

LCN is not required or One Frequency Trunked. There's nowhere to enter it.
I would run a conventional search on this system to see if any other frequencies you can hear. Looks like you should be seeing more activity but I'm not as familiar as you would be,
Hi all,
There is a type of site where there is a constant control channel which is interrupted when voice traffic is required to be broadcast. It's used on sites where extremely low traffic is expected.
I know it as a VDOC (Voice & Data on Control) site, but that may be a P25 term. I think the NXDN term might be "composite control channel".
In any case, I'm fairly certain that the LCN is available to the scanner on the control channel itself, so in essence, that's technically "control channel only scanning" as the go-to-channel command would specify the same LCN as the "CC is on channel ___" announcement.
The initial intent of the claim, though - which I was the one to make a few weeks ago - is that CC-only scanning in the traditional way - on a site with multiple frequencies assigned - is not possible on NXDN, as there is no band plan transmitted.

Assuming the radio does determine the LCN for a single channel/frequency site like this (I'll have to test that!), I guess this is more or less true - but it would be a limited 'edge case' of "control channel only" (I still really wouldn't call it that). Should the system add more voice channels to that site (you probably would not know), it would stop working properly because a voice grant would be sent for a channel that the radio doesn't know about.
EDIT: I think I've heard of it referred to as "VOC" or "composite" as well. On a related note (sort of?) - I've seen not only this type of single frequency NXDN but also multi channel systems where once all of the voice frequencies are in use, the control channel temporarily becomes a voice channel as well.

Correct.
I do have a NXDN VDOC/composite site near me. I put the LCN in when I programmed it, simply because I knew what it was. I'll change it to zero and see what the result is.
You should check with your local distributor or the division of Uniden that serves your part of the world - if you're not in the US it's not Uniden America Corporation...
Not completely true.
Correct I bought it from the USA and AU dealers wont touch them because there not AU released, even repairs require the return of them to the US if anything goes up the creek with them.
I have purchased the up grades a few years back and the cost to me was $260AU about $200US for the 2 keys for DMR and P.V.
I, as an overseas buyer, cant even register as the original purchaser with My Uniden in the USA because I'm not a resident of the USA . AU doesn't even have such a thing, we didn't get the upgrade options in Australian model Uniden radios, this is the reason why I buy US Models.
Cheers Guys.
I don't know if this belongs here or in it's own thread, but I'll start it hear.
Has anyone noticed a return of the MotoTrbo wrong Talk Group problem after the NXDN upgrade? When operating mobile with my 536HP I've noticed a slight uptick in the incidence of the the Talk Group displayed not matching what I'm hearing. Nothing major, but I know that Uniden spent a fair amount of effort to reduce/eliminate that problem.
Also, the DMR audio seems a bit muddier than it was before the upgrade.
I know that they are two separate updates, but I also know that sometimes one program (for lack of a better word), can affect another one.

I've seen this happen on a NXDN 4800 trunking system I'm monitoring on occasion. I'll see when the firmware get's tweaked if it still occurs. No issue seen on MotoTRBO or DMR systems I'm monitoring.
In my case it's both the ICE and Comtronics Con+ systems. I only have one Cap+ system programmed in my x36HP scanners and it's not busy.
I've yet to notice it on the two NXDN 4800 systems I listen to. Then again, neither is that busy yet.
