Karl Anderson (NM7N) is the subject of the article "The Fishing is Great on Mount Saint Helens" posted January 7, 2008 on the front page of the ARRL web site (
http://www.arrl.org). In it he talks about his Elecraft K2 and battery used for the backpack operation. It is a good read--and features one of our favorite rigs.
