I originally got my psr500 on 2/20/08 at that time it seemed to be working verry well. I have been scanning for 25 yrs. or better so i am no novice. I have manually programed conv. freq's , Digital freq's and trunked freq's and for a while the radio worked flawllessly for some time . However since i began downloading the new firmware's and acquiring the arc500 software and programming from the rr database the radio seems to be in att. mode, because my old por 94 is picking up frequencies when my psr500 is silent. I have reset the radio to factory settings numerous times but it dosent help . i really am at my witts end . dose anyone have any info that might help with my reception priblems . I am listening to Ohio co in west va. belmont co. in ohio and jefferson co. in ohio and marshall co. in west va. i am using the arc500 software to load the scanner now but it does not help . can anyone offer some help please . thanks Paul1. ps i live in bethelehem wv. a suburb of wheeling west va and my residence is some 600 feet above the ohio river so my reception has always been good with any scanner.
