Taking up the Torch

This month marks the return of SDM’s 5-Minute Tech Quiz following the death last year of author Ron Nelson. I am profoundly humbled at the opportunity to be able to continue this column from Ron, a long-time friend and mentor, although I could never replace him. For 16 years Ron authored the 5-Minute Tech Quiz with the hope of engaging his audience in sometimes simple yet overlooked issues one might come upon every day. Regardless of who called him, colleague or competitor, Ron would offer advice and assistance. And since Ron worked for a central station, my first column is dedicated to him and to monitoring. Here’s to you Ron. I hope to make you proud!  Roy Pollack
