Hi me1900;
The only suggestion I can make is to trim the window value down a bit more. Try increments of 0.125 in the correction value to get the window value to a single digit.
Drift is nonexistent holding at 0.0000 with squelch at 40. I don't think I want to go negative ppm. The OKWIN Motorola PII system isn't really strongest it can be in the middle of the Oklahoma City Metro. I'm having to monitor the EDACS 9600bd Provoice system. I really doubt that 300bd data hum can be eliminated now.
On a side-note, Rick, I still see a bug in Unitrunker 1.0.33.5 preview that on EDACS system after downloading from RR database 2810 It won't label the system and sticks to "Unknown" when it should say "Oklahoma City" as the system label. Still having to manually label it. No such issue on Motorola PII system.
All talk groups and frequencies are correct. It's following the system quite well though.
