My QSO this week is with Fred Regennitter, K4IU, has a rich ham radio history spanning over 50 years, from the first crystal radio receiver to his modern FlexRadio software defined transceiver. DX and contests are Fred’s interest and the new digital modes have won a new appeal for making contacts as we reach the bottom of the Sunspot cycle.  Amateur radio has expanded into a big tent that with many facets.  K4IU tells us why in this episode of QSO Today.
