I run my PSR-500 on a Onmi-Link, Multiple Site, Simo system without issue.
I am able to move around in a given site with no problems, and can roam to other sites and quickly acquire the new CC. The site I listen to most (Site 3) has 5 transmitters with overlapping coverage. In my same footprint, I can also receive at least 3 other sites which are also simo.
I do have a few areas that I get some odd interference in some areas, but I get that with other scanners in those areas as well.
I think it is about the best anyone can hope for. Since the 500/600 is providing the "latest" in simulcast decoding, I have to take what I can get. I think the performance, though, is marginal at best.
It always seems to cut out at the worst possible time for me...when something important is being said.
the only way to get good reception on a simulcast is with a good directional antenna and good cable..i have been through this with my system and it is the only way to make it work..i have a psr 500 that works great hooked to the directional on the roof but is not worth a dam portable with a RS 800 duckie..also have PRO 2096
