In Vegas, Plenty to Talk About

IP infrastructure, FM boosters, drones, the behavior of FM receivers, digital on the AM band are among topics of NAB Show engineering sessions March 16, 2015

IP infrastructure, FM boosters, drones, the behavior of FM receivers, digital on the AM band … these are among topics of engineering sessions at the NAB Show. Among the more promising:

On Saturday Wayne Pecena, director of engineering for Texas A&M University/KAMU, will give a three-hour “Tutorial: Router Configuration” as part of the SBE Ennes Workshop. “Wayne will build a network from the ground up, show us how to add access points, implement practical security [and] teach us about what we can learn from our routers in terms of traffic and use patterns,” the program promises.

At the 2014 NAB Show, Ricardo Da Silva of BW Broadcast and Alan Kilgore of WRVM(FM) in Suring, Wis., discuss FM transmitters.
That afternoon, Kevin Gross of AVA Networks will talk about “Implementing AES-67, Audio over IP in the Station and Studio.” It will be interesting to hear about “what’s next” now that AES-67, with its promise of interoperability, has been in place for a while.

We’ll be interested too in hearing what Sam Matheny, executive vice president and chief technology officer of NAB, will say in his keynote for the engineering conference; that’s Sunday morning.

Then Hal Kneller of GeoBroadcast Solutions will update attendees on “New Technologies in FM On-Channel Boosters.” It’s part of a three-hour group of presentations called “Advanced Radio Technology” chaired by Milford Smith of Greater Media. Also included are “The Curious Behavior of Consumer FM Receivers During Hyper-modulation” by Jeff Keith at Wheatstone; and David Layer of NAB gives more info about the ongoing tests of all-digital operation on the AM band.

Sunday afternoon brings a “Radio Technology Forum.” Samples: John Kean of NPR Labs will review a “Study of Audio Loudness Range for Consumers in Various Listening Modes and Ambient Noise Levels” and there will be a discussion of “–10 dB IBOC at Combined Transmission Sites” by Dan Fallon and John Schadler of Dielectric.

The senior band gets an entire “AM Radio Boot Camp” occupying most of the day Monday, with topics from RF safety and antenna system modeling to how to lease out space on towers. Monday also brings a discussion of “Preliminary Findings From Preparations for The IPAWS National Test” by Al Kenyon of FEMA, part of a track on “Technical Regulatory Issues for Broadcasters.”

A Tuesday track focuses on “Radio Facilities” and is hosted by Barry Blesser of 25-Seven Systems; it will include discussions about personal broadcast platforms, aiming parabolic dishes and Blesser’s own presentation on “Monitoring for Ratings.” A Tuesday afternoon track on “Radio Connectivity” includes a number of experts on codecs and telephony.

On Wednesday, Garrison Cavell of Cavell, Mertz and Associates moderates an all-day “RF Boot Camp,” and the Technology Luncheon is sure to be crowded when John McAfee (yes, that John McAfee) comes to speak, and NAB honors Tom King of Kintronic Labs and Richard Friedel of Fox Networks with its Engineering Achievement Award.
