Episode 518 - Dan Quigley - N7HQ

Dan Quigley, N7HQ, is a true veteran in the world of ham radio and technology. Like many of us, Dan's passion for radio began early, with a crystal radio, and earned his license while delivering newspapers to pay for his new hobby. Dan’s professional career evolved based on the specific needs of clients and customers, creating long and successful stints through Microsoft and Amazon before joining FlexRadio as their Director of Strategic Solutions. N7HQ is a kindred spirit, perhaps to many of us, and tells his ham radio story in this QSO Today.

He modified his SSB only BitX transceiver to operate CW and to use it for CW practice. As a software engineer by trade, Ram has a keen interest in software defined radio, SDR, homebrewing radios, and CW. VU2JXN is my QSO Today.
