In reply to Bob Kemp:
I used to be a Radio Operator in the Royal Navy and left many years ago. A couple of years ago I got interested in becoming an amateur and have now a registered licence.
Then I discovered SOTA.org, which combines hill/mountains with radio. Its given me more motivation to get back out into our hills and mountains, especially summits I'd not normally go to. I suppose it combines two hobbies I have - 3 if you count birdwatching too! .
Basically you get various points for 'activating' a SOTA listed summit depending on hight & whether its winter etc., which means you have to contact at least four other radio amateurs from the summit area to get your points.

Its also world wide - There are some summits in Scotland no one has 'activated' (remoter small ones attracting few points), and some in Europe & North America that are unlikely to be activated unless you're pretty good at alpine mountaineering as well as being a keen amateur.
There are quite a few continental SOTA enthusiasts who are quite good and experienced alpine mountaineers too.
