Might be better to look at posts and post in the Iowa forum....
From what RR is showing it looks like a Harris system (but that's just a guess from the fact that ALL of the frequencies are listed as either a primary or alternate control channel frequency). Others - even with the newer x36 radios are reporting problems on these systems (but I haven't noticed any significant difference from receiving other simulcast systems). The most I can tell you for a local Harris simulcast system in my state is that the system hasn't yet been built out fully (they only have like 5 towers but know they really need 13 and are building towards that - even thought the systems has been live since August).
I'm not sure how comfortable you are with programming your scanner but my suggestion is to try and figure out which frequency is actually active and being used as the control channel and only enter that frequency into your radio/system. Remove all others. Basically, this forces the radio to immediately check that one frequency right away if the radio loses sync on the CC (rather than it walking through each of the frequencies one at a time just to come back around to the same one it left).
Additionally - load this as the only system (don't try scanning others at the same time).
And - run in ID SEARCH mode or whatever the HP-1 equivalent is.
And finally - consider going close to one of the transmitter/tower sites. This virtually eliminates the simulcast concerns.
If none of this works, I'd suspect a programming problem.
Happy hunting.
EDIT: also seeing lots of Encrypted talkgroups on the system....
Ah ha!
