I don't have freescan. I'm just wondering if i just clear the site & start fresh again?
Why would you do that?
If it was correctly programmed originally (by that, I mean you were able to monitor the system you wanted), then it sound like your "nothing to scan" has occurred because you managed to lock out the only active system or talkgroup in the scanner. That you could do by hitting a quick key number, or the lockout (L/O) for a talkgroup. A single, accidental, key press is not going to delete or modify your programming (other than the lockout status). Deletion or modification (or editing, if you prefer the term) requires a series of keystrokes, and selection of appropriate menu options.
Try resetting the lockout as I suggested earlier. If that does not work, or if you'd really prefer starting 'all over again', you can clear the scanner memory by turning it off, then pressing & holding the 2, 9, & <Hold> keys while turning the scanner back on. You'll get a prompt warning you that this will clear the scanner memory, so accept that, and you'll get another prompt asking if you want to load the pre-programmed systems that came in the scanner originally. I would say "no" to that, since that information is mostly out of date, and would include information from all the states.
Personally, I wouldn't go to that extreme, which is like using nuclear weapons on a fire ant mound. I'd correct the lockout status of the existing system & or talkgroups. The Nothing to Scan page linked above and the Easier to Read
manual both have details on how to edit your existing system.
The use of
software, such as FreeSCAN, ProScan, or ARC-XT would allow you to simply reload the scanner programming in a couple of minutes,, and you would be back in operation.
