Episode 399 – John Raydo – K0IZ


John Raydo, K0IZ, had a great mentor at the beginning of his ham radio story that laid the foundation for John’s approach to operating amateur radio and building radio equipment from scratch. John shares this story and how he now remotely controls and has the noise benefit of his rural Colorado rig when operating from his QTH in Missouri.  K0IZ is my QSO Today.
