Four years ago Philipp Schmid at Nautel introduced HD Radio technology allowing up to 15 digital program feeds on one FM channel. They called it “Multiplex FM”. Now the idea and technology have expanded to include the DRM (Digital Radio Mondiale) transmission system. What’s more, Nautel and Telos Alliance have demonstrated a cloud-based system for processing multiple HD channels along with the analog FM program, with reliable Internet delivery to transmitter sites. Philip and Alex fill us in on this technology on TWiRT!
