Whenever propagation has allowed, I have been chasing some of the Youngsters On The Air (YOTA) stations, predominantly on 20m.
From the YOTA website……
Youngsters on the air is a highly motivated group of people of all ages and from all over the world working together tightly to make sure that there will still be somebody to answer your CQ call in the future. We ensure that there is a next generation of amateur radio enthusiasts which bring new energy into the hobby. The future of amateur radio rests on the shoulders of Youngsters On The Air but without your support amateur radio might die out in the next decades.
I have worked a number of the YOTA stations and have achieved 15 points and in turn, have qualified for the YOTA certificate.
