5MHz band - RSGB notice

See http://rsgb.org/main/blog/uncategorized/2014/04/08/important-update-5-mhz-band/ .

The primary user is carrying out some exercises in the next few days and amateurs (secondary users) are asked to use the channels we have carefully to avoid interference to the primary users.

So far, I have only used the band for WSPR on a couple of occasions. It was fun.
