Everything You Ever Wanted to Know about SOTA
Brad (the Voice of the Village) Berger
Here is a lot of good information on SOTA (Summits On The Air). Summits On The Air is a scheme that encourages amateur radio operators to go portable and work from high places around the country, and around the world – You don’t need to be a mountaineer to take part, and if the idea of climbing mountains and hills in the name of amateur radio doesn’t appeal, then you can be a ‘chaser’ sitting comfortably at home working the more adventurous SOTA operators. My friend Ken KD9PPH in Spfld. IL sent this to me.
Thanks guys having me present my SOTA gear/antennas etc ...here’s the links to topics in my show Please note: I’m no expert or EE but just an experimenter at heart and this is where I stole my intel on how to make my EFHWs and traps etc ...so to speak! Have fun, Steve/wGOAT (WG0AT)
