SOTA or Summits On The Air is a really neat way of combining walking and amateur radio. There is a website dedicated to this side of the hobby at www.sota.org.uk/
In a nutshell, Radio enjoys the clear views and height on top of the hills as much as I do. At height you can get a really clear signal and speak with contacts all over the world.
I got my amateur radio licence on the 5th January 2017. My callsign is 2E0KUK.
I can be found out on the hills most Sundays, and I can be tracked here
