Episode 233 – Ray Waldemar – WA6NVL

Ray Waldemar, WA6NVL, is an early adopter of electronic technologies that find their way into amateur radio including the first Apple 1 computer, first instances of repeaters, remote base stations, digital modes, D-Star, and now DMR.  Active on HF, VHF, UHF, and Microwave, from SSB to satellites. Ray just likes it all for the technical challenges and the social connections he makes from almost 50 years in the amateur radio hobby. WA6NVL is my QSO Today.
