Hi, im in Columbus ohio and i downloaded from win 500 the channels i wanted to my scanner. which was zone 3 dispatch, Columbus fire and sheriff, but im not getting everything and its not coming in that clear. when i was in the win 500 program i got the system frequency but i didn't choose nothing from the trunking tables. i went through it and seen p-25 700 MHz, 800 MHz and 900 MHz. So i was wondering if i chose the p25 800 MHz would that make the channels come in better and clearer. Thanks
