I know that newer scanners and radios don't cover the frequencies used by hand held phones. (The radio link between the hand set and the base unit that is connected to the actual phone lines.) Maybe that model doesn't have that section of frequencies blocked.
The NS 3000 is a 10 meter mobile radio trans/receiver.
From what I can gather, it has something to do with it being citizen's band with additional sw frequencies??
Yeah, I did a little research on the NS 3000, and I think omega is right - it looks like a CB, but it will run on 10 and 11 meter bands. Truckers and preppers like to run without a license on the 10 meter band which, I imagine, causes a lot of friction with the ham radio community. The NS 3000 is also not type accepted to run legally on the 11 meter CB band. That means using it as a CB would be like using one of those Chinese HT's (like my Baofeng) on GMRS.
If I had one, I'd still use it - it appears to be a nice radio. As long as you follow radio etiquette, I doubt anyone would notice. Usually the FCC doesn't enforce many rules, unless there are a lot of complaints. My guess is you can thank a bunch of foul-mouthed truckers for stepping on amateur bands and getting these radios banned for import. Take that for what it's worth - its just my uninformed opinion, from the little research I've done on the topic.
