In September 2019, at the Radio Show in Dallas, Texas, “Tech Tuesday” debuted with an all-day program featuring content on the latest developments in radio technology. Shown above is a panel from Tech Tuesday on all-digital AM, moderated by David Layer, NAB, and featuring Russ Mundschenk, Xperi, and Dave Kolesar, Hubbard Broadcasting.

While this year’s Radio Show has gone virtual, NAB is proud to present another strong technical lineup, offering a 30-minute technical session each day during Radio Week, October 5-9, 2020. This blog features a short description of each session. For more information about attendance and registration visit the Radio Show website.

3:30-4 p.m. ET | How Radio Broadcasters can Support RadioDNS

With hybrid radio-equipped vehicles by Audi and BMW now appearing in the U.S., radio broadcasters need to get registered with RadioDNS so their stations can take advantage of the additional station-data presentation and streaming-audio capabilities that hybrid radio receivers provide. This session will provide information on the steps needed to provide RadioDNS support, stressing how simple it is and how it can easily be done in-house.

  • Nick Piggott, project director, RadioDNS
  • Jason Ornellas, director of Engineering, Bonneville International Corporation
  • Mark McConnell, system administrator and digital content manager, Bonneville International Corporation

3:30-4 p.m. ET |  All-digital AM – A Progress Report

WWFD in Frederick, Md., is now in its third year as the first all-digital AM station, and other AM stations have subsequently obtained experimental authority from the Federal Communications Commission (FCC) to switch to all-digital. We’ll hear from Dave Kolesar at WWFD on the latest lessons learned at his facility as well as from Brian Walsh at WIOE in Fort Wayne, Ind., the newest all-digital AM operation in the U.S.

3:30-4 p.m. ET | Broadcast Equipment Evolution – From Hardware to Software and into the Cloud, Part 2

Broadcast equipment manufacturers have been making strides in simplifying facility infrastructure and preparing for the day when broadcast operations become less of a capital expenditure and more of an operational cost. In this session we’ll hear from broadcasters and developers who are paving the way to simplified – and ideally, cost-reduced – technical operations. The first part of this two-part session considers virtualization of traditionally hardware-based systems. The second part covers next-gen HD Radio architectures.
