Nova might be Nova Scotia Canada.I don't know where NOVA is, or what type of radio system(s) being used there, so I can't give you specifics. However, most people on here are able to scan conventional channels with few or no problems. But when they want to monitor a trunked radio system, it is a huge hurdle. So I'd want to start reading up on Motorola, EDACS & LTR type trunked radio systems and understand the difference. There are other systems as well, but those are the only 3 presently supported by scanners.
+1The one's that apply to that new persons unique situation.
