I too had some difficulty learning WIN97, but it's breeze once you get the hang of it. The registered version (well worth it), may allow you to automaticall import control frequencies then pick and choose talkgroups within and put them in banks wherever you want.
I've not checked for your area so don't know what type systems they use in your neck of the woods. MOT is pretty easy to set up and use.
I too wanted ONLY to listen to a certain group of FireDepartments, PD's, and tac op's, some aviation frequencies, and other less listened frequencies.
This thing drove me nuts until I FINALLY understand the concept of how trunking systems work. I was an old school guy that was used to just conventional frequencies, so trunking was completly new to me.
You'll get the hang of it. I'll got back and look at your specific area and see what I can come up with. That will at least let you know what you are facing it getting it set up.
Here is a screen shot of stuff in your area
Good Luck!
