CG - have a full bars when i am listening to the state system pretty much everywhere
That really doesn't determine much at all. The "bars" are just a basic RSSI indicator on the level of signal coming in on that RF port either at or adjacent to the frequency. The quality of reception can only be determined by other factors. (There is a measurement for this on the SDS, but I forgot off the top of my head what it's called. Digital decode or something). And just because you have reception bars maxed, doesn't mean you're not going to have simulcast distortion. CLMRN, with the sites, is notoriously bad for it, unless you are in an area where one site just simply overpowers everything and you don't get reception from any other site. The 996P2 is simply a poor simulcast receiver. This is very well documented and tested. The 536, which is a better overall receiver than the 996P2, still doesn't handle simulcast distortion well at all.
I've mentioned a few times here, in my rather frequent trips across CT, side by side, my SDS100 out performs anything else on CLMRN. Litchfield, Hartford, Middlesex, Tolland and Windham counties, I've driven just about everywhere in those counties, and seen the results.
There are no programming tricks to get around this either, as you inferred earlier. That's not how the scanners actually work. It's great you seemingly have good luck with it, but that's simply due to your location and the site you're receiving. But your idea of programming everything into a single site means nothing. The scanner stops on the next control channel, decodes it and receives based off of the decode. If you put the Troop H in one Bank and Troop D into another, or put both control channels into the same bank, it'll just hop along. None of this has anything to do with simulcast distortion.
