Bob Heil, K9EID, is no stranger to ham radio, as a pioneer in audio systems, not only for the rock and roll stars in the 60’s and 70’s, but for ham radio as well. As the founder of Heil Sound, Bob’s injection of audio experience and know how has raised the bar of what is acceptable for good sounding voice communications on amateur radio. Bob shares his ham radio story with Eric, 4Z1UG, on this episode of QSO Today.
