Is MARCS a simulcast system? Here in Worthington I get choppy audio that cuts in and out much like it would on a simulcast P25 system. I have the Columbus site programmed in, which gives somewhat choppy audio. Since I live near the Delaware County line, I deleted the Columbus frequencies and tried the Delaware site frequencies and the reception is slightly worse. Does anyone else have this problem with MARCS? I am using a PSR-500, and I've experimented with the Multi-Site feature and I still get the same problems, however the reception is at its "best" when the feature is turned off.
