Just wondering:

1) Is the UK govt doing this?

2) Is the USA doing anything similar?

3) What's the purpose?

4) Have you guys using GPS over there been affected?

(PS - If you email me and don't get a quick response, don't be concerned.
I get about 300 emails per day from alternate energy mailing lists and
such.  I don't always see new messages very quickly.  If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
