On this episode of This Week in Radio Tech, Kirk Harnack is joined by broadcast engineer Aaron Read of L and R Broadcast Services, formerly with Rhode Island Public Radio. Aaron shares thoughtful, experience-based insights on how broadcast engineers play a direct role in establishing—and sometimes unintentionally eroding—listener trust, and why that trust remains one of radio’s greatest strengths. The conversation also dives into Aaron’s practical “Tip of the Week,” focusing on securing Barix codecs and other IP audio devices, including why built-in security features and proper password discipline matter. Aaron strongly advocates for using site-to-site VPNs to protect studio-to-transmitter IP links, explaining how this approach improves both security and reliability. Throughout the episode, Aaron emphasizes the importance of remaining open-minded and committed to continuous learning as technology and workflows evolve. This is a valuable listen for engineers who care about protecting the craft, the signal, and the audience relationship.
