Broadcast TV antenna manufacturers should make some good sales numbers in the next couple of years as the FCC forces broadcasters to shuffle channels again. This time around, the emphasis will be on broadband designs. Jampro has been working to make their antennas work on multiple channels with minimal wind loading. Many broadcasters will be looking at designs that make the best use of ATSC 3.0 as well. There are things to keep in mind you as broadcast engineers may not have considered, like OFDM Crest Factor and circular polarization for mobile coverage.
As a bonus, they plan to talk about their experience in Singapore with DVB-T2 and Single Frequency Networks.
Join us March 15 at 12 noon at KGTV, 4600 Air Way near I-805 and CA-94 in San Diego for the Chapter 36 regular monthly meeting. Jampro is buying lunch in the cafeteria.
What are the capabilities of modern test equipment and its ability to test very low noise and distortion devices? Can test equipment of today keep up with increasingly impressive specs? Are the specs real? We’ll review some real world examples from both the electrical audio test world as well as room acoustics testing.
Join Chapter 36 Wednesday, February 15, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Audio Precision buys lunch. Members and visitors are welcome as always.

An attentive crowd at the KFMB studios heard Sumnit Singh make a case for using the technology developed for consumer mobile devices to relay news audio and video to broadcast outlets over private networks. It should be interesting to see if stations step up to the plate to capitalize this evolution, or if an organization will step up to finance the movement and then resell to broadcasters, or if the technology will die on the vine before being rolled out.
The SBE gang held its annual holiday luncheon this year at Mimi’s Cafe in Mission Valley and had a great time of it. Congratulations to those who walked out with prizes. Nigel Worrall received a ham radio handi-talkie from RF Specialties. Bob Gonsett, Steve Frick, and Barbara Lange walked off with chocolates or wine from Piper Digital and Utah Scientific. Everyone got great food and conversation.
When broadcasters swap CD’s, cart machines, turntables and audio consoles for PC-based digital playout, mixing & processing systems, we call that Virtual Radio. At our next meeting, guest speaker Bill Bennett, Lawo’s Radio Applications lead in the U.S., will describe virtualization in greater detail by outlining the real applications in use today. He’ll explore how broadcasters may now reap operational benefits and gains by capitalizing on I.T.’s investment in R&D and will discuss virtualization’s anticipated role in content creation and broadcast workflow in the future.
Virtual Radio is a hot topic. A recent episode of This Week in Radio Tech (TWiRT) featured a Lawo presentation on this topic. How did they conduct their broadcast interview? Virtually, of course!
Lawo is a provider of virtual radio products, digital mixing consoles, routing systems, video solutions and turnkey systems for the professional broadcast industry. Their equipment is utilized by TV and radio stations, production companies, and theaters worldwide.
Bill Bennett made his presentation Wednesday, November 9th, 2016 at iHeartMedia, San Diego before a sizable audience of local broadcast engineers.
