G0KSC

Episode 211 - Justin Johnson - G0KSC

Justin Johnson, G0KSC, tells his ham radio story and how it led to the founding of his company,  Innovantenna, and his approach to antenna designs, that maximize signal to noise, rather than gain, to produce amazing results. If you are re-considering your antenna system, then you will enjoy this QSO Today with G0KSC.

Most excited by:  6 meters, SDRs and digital modes, SDR Radio , and low noise yagis

Advice to new or returning hams:  Join forums about digital modes, try the weak signal modes, and buy a rig with a built-in PC interface for digital modes.
