What if you could transmit fifteen radio program channels from one FM transmitter, and receive them on existing FM-HD radios?  Philipp Schmid, Research Engineer at Nautel, has been demonstrating exactly that.  How does it work, and why might a broadcaster want to do this?  Philipp joins Chris Tobin and Kirk Harnack to explain.
