First licensed in 1956 as KN6RDJ with lots of assistance from W6LYJ my high school physics prof. Have enjoyed providing emergency communications for local civil defense and AREC activities in and around the Redwood City to San Jose, CA in the SF Bay Area for many years. Interests are mobile and portable operations with a keen interest in QRP especially building and designing small, trail-friendly gear. I currently run a Small Wonder Labs SW-40+ built into a Hammond cast aluminum box together with an L-section antenna tuner, absorptive SWR meter, and an Embedded Research dc-dc converter running off a set of 8 Alkaline AA cells. The dc-dc converter does a bang up job of providing fixed 12 vdc over an internal battery or external input range of 6 to 16 volts. I also enjoyed designing a paddle key which plugs directly into the front of the rig. I just managed to 'squeeze' in an NE-QRP SCAF filter into the Hammond box I have the rig in. Tight, but sure helps reduce effects of QRN/QRM and brings up the signal being copied out of the noise.
