TWiRT 305 - HD Multiplex with Philipp Schmid

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.

TWiRT 303 - Hey, We Found Chris Tarr!

What’s an engineer to do when the old transmitter you’re getting rid of won’t fit through the building door?  You could cut it apart with a Sawz-All, or you could break out a wall and make a bigger door.  Well, Chris Tarr used both strategies during two recent transmitter upgrades.  The Ninjaneer joins Chris Tobin and me for a TWiRT reunion episode.

TWiRT 302 - Virtual Machine Tech and Radio

Virtual Machines have been used in computer data centers and corporate IT systems since the late 1990’s, with popularity skyrocketing in the past 5 to 8 years.  Today’s VM technology is allowing broadcasters to run several automation and production systems on virtual computers - on hardware that’s fully redundant.  Dave Turner from ENCO joins us to tell us how this all works.
