Thanks Graham for that info and link.

I had PPL on the phone this morning, apparently they are not going to fine me for the years that I have had a radio on in the workshop, but will back charge me for last year and also charge me for next year.
The figure they want is around £140.00.

I can now tell them to go back amongst those pesky callers who want me to advertise in the 'emergency services' booklets that never seem to get printed. (yes I've been stung).
