Thanks UPMan. You are correct again

I am using FreeScan so the option to select CC Only is there but I don't see it in the radio when on P25. I set ATT and I see some improvements but still choppy audio around the tower. My station location is a probably a perfect storm for the simulcast issue as it is exactly in the middle of two ant sites. I see the same choppiness as I do near one of the towers.
I am imagining that this could "simply" be a system that is not in standard spec rather than a scanner issue.
