Been doing a lot of listening on the the Litchfield Site over the past couple of months. (LCN's 4, 14, 24, 34 Color Code 3)
Programmed conventionally in a 996P2 with DMR upgrade and listening to all traffic I heard many crews doing day to day work and of course a lot more traffic during storm situations. Keeping hold and delay times at zero it very easy to follow and listen to all conversations completely. The system isn't that busy yet even during storm work. I'm not able to scan the control channel (LCN 14) conventionally because the scanner will just sit on it and not scan anything else. Because of this I'm assuming that I'm missing the ability to listen to 1 voice slot in this site. I'm assuming that the control channel uses 1 slot for the data stream and has 1 slot available for voice. (I'm assuming - certainly correct me if I'm wrong as I'm still learning about DMR systems) However it doesn't seem like the site uses this slot much if it exists. It seems to prefer LCN 24 and 34 for most voice traffic.
I did hear radio service checking levels of these channels directly a few days ago and they were called out by their channel numbers so the LCN's listed in the data base for the Litchfield site of 4, 14, 24 and 34 seem to be verified as correct. It does appear that in this system LCN 1 starts off with LSN 3&4 so the LCN is the even slot number divided by 2 minus 1.
For a while it appeared that traffic from this site was being simulcasted on the old low band 48.400. That seems to have ceased and most line trucks and station electricians vehicles appear to be fitted with new radios which are being used.
Lastly, I also programmed this system in a 2nd DMR upgraded 996P2 as a DMR tier 3 with the frequencies programmed into a "site" with proper LCN's and color codes and the talk groups properly programmed. I left the groups on search rather than scan to make sure I wasn't missing any undiscovered groups. When compared side by side to a 2nd 996 scanning the frequencies conventionally, the 996 scanning the system as a DMR tier 3 only receives around 10% - 15% of transmissions. it misses the rest. It does display the proper talk group. "Western Ops" seems to be the most used during storm work.
So it's definitely confirmed that Uniden scanners struggle to track this Tait DMR system when its actually programmed as such.
@JoeBearcat any idea if there will be any Uniden firmware upgrades coming that will solve this issue ?
If anyone has any more info or corrections to what I've observed feel free to follow up.
