Episode 222 - Greg Latta - AA8V

In episode 33 of the QSO Today podcast, Dr. Greg Latta, AA8V, was described as a renaissance man, a master homebrewer who designs and builds the old tube rigs and fabricates the beautiful metal enclosures that encase them.  Greg is also a college physics professor who says that vacuum tubes are one of the best ways to provide to students a visual representation electrons in motion. We reprise and update this QSO with AA8V.
