Episode 445 - Nick Tusa - K5EF

Nick Tusa, K5EF, embarked on his ham radio journey as a teenager in a New Orleans Jesuit high school, where he was introduced to the cutting-edge technology of a Central Electronics 10A SSB Exciter at the school's ham radio station. This early fascination sparked a lifelong friendship between Nick and Wes Schum, W9DYV, the co-founder and chief engineer of Central Electronics. Over the course of their 50-year friendship, Nick not only built a successful career in radio and communications but also became Schum's biographer. K5EF is my QSO today.
