The "Roam" and "Stat" modes for the PSR-500 are nice (basically with these two modes, you can program in multiple sites in a single TSYS object (which is where you store the actual info for control channels; talkgroups behave just like conventional frequencies with the PSR-500) and the PSR-500 will automagically see which control channel has the highest signal level and decode rate, then will lock on from there till it drops below a certain threshold then it starts internally "scanning" for the strongest signal and so on)--definitely a very fun toy with multiple-site systems like SAFE-T. It's definitely worth it IMHO, but then again, I've always been a fan of GRE kit. Your mileage may vary.
Interesting that you're picking up the Fort Knox system as 9600bps APCO-25. (Again, though, I could be in a fringe area for that system. Hence why I'd like to try it out in Shepherdsville or West Point or somewhere actually *closer* to Hardin County to test things out with. It could also be a difference on how the Uniden and the GRE radios handle things.) I can set the mode to P25 Manual on the test setup for KYSP (presently it's on P25 Auto) and see if that helps at all, though.
I am leaning towards "fringe area" being the culprit, BTW, on why I can't pick up the Ft. Knox system reliably. I can pick up KYSP pretty well, but both transmitters near me are roughly 15mi from my location. (The PSR-500 is easily the most sensitive radio I've owned yet, so it's not a matter that it's deaf at that frequency range.)
(For that matter, I also now need to add the new KYMAI freqs that were recently found on here to see if we can pick up the NAC codes for those. Did I mention the PSR-500 does NAC natively? Did I mention this is just about the best thing since sliced bread if you're on a "border area" monitoring KYSP?
