Tech Notes features technical articles submitted by our customers and others.  Topics can be Elecraft related or more general interest. Articles range from radio mods to technical 'how to' write ups. New articles will be posted monthly (or more often) and previous ones will also be archived on this page. We hope this page becomes a clearing house for useful information to the amateur radio community.
