PRO106. Garbled audio on P-25.

[Befuddled]

When listening to Illinois StarCom 21 on a PRO-106 the audio is usually garbled, choppy and unreadable. Occasionally, though, a transmission will be loud and clear. I have programmed in site 1-013 (Will Co. simulcast) with a half dozen or so talk groups. I am set for P25 Auto, the 3 appropriate control freqs and Multi site STAT. The same talkgroup and frequency may be garbled on one transmission and clear on another. I am located about 6 miles from District 5 headquarters, and the signal strength is very good. What am I doing wrong?

Set for ROAM and turn on DSP.
Also BECAUSE you're so close there is sometimes an issue with multipath, so try relocating the radio and/or the antenna.
I am 3 miles from the site 2-29.

Do a search on "simulcast distortion". My 106 does this when I go to Naperville and listen to the Elgin and Will Co. sites.......Roninjoliet is very knowledgeable about this topic....

Also trying setting the Narow FM: to yes. This helps a little bit also.

Welcome to radio.

You oughta hear what it sounds like on genuine Starcom radios. It may not be a problem on your end.
