Retired Emergency Medicine physician, and USAF flight surgeon. I stumbled across HAM radio a couple of years ago, and enjoyed the multiple challenges it involves. I am trying to teach myself radio theory, electronics and basic programing. Interested in improving my modest station without resorting to high power amplifiers. I enjoy low power transmission, receiving satellite data and building my own antennas, all with the goal of improved performance with only 5-100 Watts.
