I have BCD536HP and have a single system ICORRS P25 APCO programmed and only scanning one county. I have plenty of signal. Certain feeds are garbled or choppy and cut out. Since it's a trunking system, I can't adjust any of the P25 settings. I have tried turning on and off the digital AGC and leaving it off has some improvement. I have a 996XT that decodes correctly. Is there any way the P25 settings can be adjusted in trunking mode ? It seems like the threshold isn't correct...Any suggestions will be greatly appreciated... thanks in advance..
