Hello,
I am the person who entered their MOTOTRBO CAP+ system into RR. I was there a couple weeks ago and brought both my Uniden BCD325P2, (the scanner I used to initially track the system), and my VHF Motorola DMR portable. I programmed my Motorola radio in a way to be able to monitor 16 talkgroups as an RX list by monitoring the control/ voice channels as conventional channels in a scan list.
As mentioned above, the data bursts and possible data on any of the system channels would mess a standard DMR radio's scanning up, including the config I used in my Motorola DMR radio.
If you have a DMR scanner, I recommend listening to the system! It has a lot of activity and operations are pretty interesting across the talkgroups. In the two days I was there, I heard all of the talkgroups listed for the system plus more which I still consider unconfirmed.
I'm not affiliated with Knoebels, but I've been going there for a while and it was fun to scan their system.
Have a great day and 73!
