Have a PRO-106 for about a week now and everything is working great. Purchased the RS communication cable and installed ARC500 and became a member of RR online. Just a quick question cuz I can't seem to find my answer from many searches in this forum. Say I created a long list of frequencies for only my county and upload them to my scanner yesterday. Scan list 1. Then today I want to add the counties that surround mine. If I upload this new list to my scanner and also called it scan list 1, does it completely overwrite what's there already or add to it, or what. Yes I could name it scan list 2 but I just want to understand what it does with a "same named" scan list. Thanks, and I love this website.
