Episode 513 – Lee Barrett – K7NM

Picture
Lee Barrett, K7NM, has had a wonderful career, in broadcast radio,  military projects, command and control, spacecraft, and medical device development.  His early initiation into amateur radio set in motion all that came later in both professional and amateur radio life. From early in his ham radio career, Lee published papers on vertical antenna beam tilt for repeater networks, and well as his most recent “C-Match Method of Phasing HF Vertical Antennas.  He was a presenter at the QSO Today Virtual Ham Expo, speaks to radio clubs all over the United States, and at the Dayton Hamvention.  K7NM is my QSO today.
