Southgate Amateur Radio Club, eHam,Net and other sources have reported a story of an amateur radio operator who was injured during a hike in Washington state in the USA. He made a transmission which was picked up by a station over 600 miles away. That station was able to initiate a rescue.
Anyway, read the full story from Everett, WA here.
If you enjoy Amateur Radio in the outdoors, this is a great reminder to make sure that someone knows where you are, when you should be back and to make sure there are ways that you can raise the alarm if something goes wrong.
