UMA is an LTR you need to program the Radio for LTR Trunking with the channels in Logical Order. What you hear is the system polling.
Nothing new has been submitted since early 2008
so any changes from the RR DB
would be great.
I would suggest reading the WIKI on LTR and it will help you deceipher
the info, to post to the RR DB with some valid updates.
