If you're referring to the radioreferenceuk.co.uk website, that has nothing whatsoever to do with radioreference.com (the site we're on now).Has there ever been any thought of radio reference UK maintaining a database the way it is in USA.
Although there are obviously listings here on RadioReference.com for the UK, the issue is that it's Uniden America that maintains the Sentinel database, and frankly they only seem to care about customers in North America. Well, the U.S.A. and Canada more specifically, as those are the only two countries they pull data from for Sentinel...Mexico gets no love either.
