Is there a way to get these DMR channels to scan faster, And why is my scanner skipping frequencies?

Alright this has been a problem for awhile i have tried programming every way you can i have used OFT and conventional but i get the same results.
HERE is the system and on dsdplus there is a data signal on all the channels it will go away at times but stays constant but when the my 536HP or SDS100 comes to that system it basically slows waaaaayy down and cycles through each channel really slowly , I know that it has to check the signal and see if there is any activity on it but i have tried to read as much as i can from other posts and some of it i don't understand as much but is there any way to tweak anything or a way to set it up so it isn't so slow?


Also i have a P25 phase 1 conv channel that has a really strong signal and i can set dsdpllus to it and it will decode clear and strong but both my scanners pass it up i tried using P25 OFT and conventional and my scanners won't even see it but dsdplus is decoding it fine with 0 issues i tried setting a hold time and delay times but this really has me suspicious of my own scanners because if they are passing up frequencies that clearly have a strong signal with traffic then who's to say it isn't passing up ton's more active frequencies i have set in my FL?.

Just very confusing stuff and if anyone has any advice i would really appreciate it . Thanks.

It looks like this system is composed of 5 sites. Have you tried programming only one site instead of all sites? This could be beneficial if all of the traffic is carried on each site.

Does every site carry the same talkgroup(s) (only one is identified in the RRDB) Why not just site hold on the site closest to you?

Also i have a P25 phase 1 conv channel that has a really strong signal and i can set dsdpllus to it and it will decode clear and strong but both my scanners pass it up
Is the applicable service type turned on for the talkgroup carried on this frequency?

Thank you i will try that right now and see.... i don't understand why neither of my scanners will pick up this channel when before it use to pick it up fine it's a P25 conventional channel dsdplus will let me hear it fine but my scanners sometimes if i park on it i will hear some traffic it's not the signal because it's strong .

Yes the service type is turned on for the p25 channel . it does carry the 25000 talkgroup but sometimes it will show different talkgroups

Scanner speed and screen speed are two different things. The Uniden scanners tend to scan at about 80 channels per second, while the scanner screens refresh about 10-15 times per second, often less.

When scanning a trunked system, it'll stay on the control channel for a bit longer, so it would know what channels to go to that are active. This isn't the scanner's fault on any slowness, but the speed of the control channel itself.

Thanks i tried narrowing it down to just one site and i will test this some and see how it goes but as long as it picks up i think this will work with speed i don't see how i didn't think of this before lol.

Now why neither of my scanners will stop on this P25 channel when dsdplus is decoding it fine is beyond me i'm using the same antenna on everything but like i said it makes me think i'm probably missing tons more .
