I currently live in Waldorf, MD and am using a PSR800 to monitor the Charles County Sheriff's Office. I think I am hearing most of the calls and not suffering from simulcast distortion. I am looking for someone in my area that has an SDS100 that would be willing to help to determine if I am actually missing calls on the PSR800. I am happy with my PSR800 and don't need to upgrade if I am hearing all the calls.
If Charles county is going to Phase 2 (TDMA) in the future and you are happy with the PSR-800, I'd wait until they actually get the new system online and working a year or so from now to see how the 800 handles it.
I have a PSR-800 and a PRO-668 and a TRX-1. They all handle Phase 1 and Phase 2 simulcast systems reasonably well, especially considering the cost of all 3 together vs the cost of 1 SDS-100. I don't need to hear every single word of every single transmission on every single TG, so they do the job just fine for me.
Another reason to wait would be to see if they encrypt everything as is all the rage right now. Especially on a 'new' system.
Why spend that kind of $$ on a SDS-100 now and end up with a radio that won't do much on encrypted TGs.
Just my 2 cents worth.
