QSO Today Podcast - Interviews with the leaders in amateur radio

Andre Hansen, K6AH, and his team of open source developers have taken amateur radio mesh networking to a new level with AREDN, that allows commercial low cost WIFI routers and access points to be used to build out local and regional broadband networks in the amateur bands above 2 GHz. Andre and I discuss this technology and its possibilities for the amateur radio community in this QSO Today.

Kristen McIntyre, K6WX, is the president of the Palo Alto Amateur Radio Club, in the heart of California's Silicon Valley, and an ARRL Pacific Division Vice Director. Trained as an MIT electronic engineer, she was an entrepreneur for many years in Japan. Kristen is a much sought after speaker at amateur radio conventions and forums. Antenna design, digital modes, and just getting on the air is key to Kristen's amateur radio success. K6WX, is my QSO Today.

Richard Dillman, W6AWO, is the founding member of the Maritime Radio Historical Society, where they preserve the skills, traditions, and folklore of maritime telegraph operators, from the California Bay Area coastal station, KSM. The "Summer of Love" brought Richard to California, in the Sixties, to pursue broadcast engineering and a 30 year career with Greenpeace. W6AWO is my QSO Today.

Dan Gravereaux, N1ZZ, began his ham radio story as a kid leading to a career in electronics, a stint at the CBS Labs working on quadraphonic sound, and later founding West Mountain Radio creators of the Rigblaster interfaces for HF digital modes. West Mountain Radio also popularized the ubiquitous Anderson Power Poles that we all use now and love. N1ZZ shares his ham radio story and expertise in this QSO Today.

Fred Lloyd, AA7BQ, is the creator of perhaps the Internet's oldest ham radio resource, QRZ.com. With over 700 thousand subscribers, QRZ.com is the goto place for hams wanting to look up other hams in its call sign database. It does however, have a large number of other resources available to amateurs that Fred and Eric, 4Z1UG, discuss in this QSO Today.

Ray Waldemar, WA6NVL, was an early adopter of electronic technology that found its way into amateur radio including the first Apple 1 computer, first instances of D-Star, and now DMR.
