I keep my wildcards open and save anything new that pops up. I have several that RR's page on AWIN does not list. There seems to be several in my area that are used for talk around, no specific agencies identified yet but I keep listening. Since I use Win500, I edit them after saving to flash the LED and double chirp. That way I know to pay closer attention to what is being said.
Part of the lure of scanning!
