    After looking at the list of sites https://www.ordnancesurvey.co.uk/docs/gps/OSNet_GPSWebSite_Coordinates_File.txt , I was tempted to see if I could find my local one, LINO N 53 15 00.918762,W 000 31 12.370061 in ETRS89 on Google Maps (WGS 84).  Google Maps shows it on top of a government building in Lincoln, and believe it or not, Satellite at maximum magnification shows the red marker almost on top of a small white round dot.  Could this be the aerial?  No need for a guard dog in this situation.

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
