Bert, Yes, and just exactly when do you think we'll stop broadcasting analog FM? The system is designed so that if the digital signal fades below reception threshold, the receiver switches to analog. No cliff edge effect. We now delay our analog signal by 8 seconds to match the digital stream for this reason. My prediction for analog FM cutoff is just shy of Doomsday.
