I travel through Polk County (Florida) which runs a P25 Phase 1 CAI Exclusive system. Work takes me through 20-25 county/city systems on a regular basis, and this one is by far the one that my 436 has the most difficulty with. I run either I-4 or SR60 across the county, so I hit a pretty good sampling of towers/conditions.
I'm no expert, but I believe that I'm encountering both LSM distortion and low signal strength at different locations during my trips. I also carry a P7100 specifically for monitoring Polk County because the 436's performance on this system is so poor. I'd estimate that I'm only hearing 60% of the traffic with the 436. I've tried numerous antennas, attenuation, everything that I can think of - nothing seems to help.
My question is this. Manual P25 threshold adjustment mode of 7 or 8 achieves good results while stationary with good signal strength. Would there be any advantage to using auto versus manual in the varying conditions while mobile? I've used both, and the advantage is not glaringly obvious in favor of one or the other. Just wondering if there is a theoretical reason that one would work better than the other.
And Uniden techs, if you're reading this, fly your family into Orlando, drop them off at Disneyworld, and head west on I-4 across Polk County. This system is certainly a worthy opponent to the 436's decoder. Just make sure you bring a professional grade radio, because the difference is night and day.
