Once again Chapter 36 will meet to simply talk shop, share some cheer, and toast to a great coming year.
Our past meeting place, Cozymel’s at UTC, is now rubble, so we’ll gather at Casa Machado, 3750 John J. Montgomery Drive, on the south side of the runways at Montgomery Field in Kearny Mesa, San Diego. Date is Wednesday, December 16, 2015. The meeting time is a bit earlier, at 11:30AM.
Please reserve a spot if you intend to join us so that we can plan sufficient table space. Whether you’re a member, a guest, or just came to town, you’re welcome. Expect to spend about $15 – 20 for lunch and a tip.
If you would like to donate a gift for an exchange, let us know and bring it with you.
If you work at a typical broadcast station, you have a number of little boxes under a console or in the back of an equipment rack. They amplify the lower level of a prosumer audio playback device, mute a speaker, or digitize an audio feed. Hank Landsberg is one of the original interface box makers and says he’s sold 120,000 little blue boxes. He still makes the IHF interface amps, but now offers a wide product selection, including a new AES audio switcher, PowerClamp surge suppressors, and A-to-D converters.
Come meet Hank and learn a thing or two about how he got started, what’s different about his blue boxes, and what’s new to the line-up.
Join us at iHeart Media, 9660 Granite Ridge Drive, San Diego on Wednesday, November 18th at 12 noon. Henry buys us lunch. All are all welcome. Continue reading November 18 Meeting: Henry’s Little Boxes

The “Importance of Proper Grounding” SBE webinar will be presented on Thursday, July 23 at 2 p.m. ET. The one-hour program will review the elements of a building’s wiring and grounding systems (including lightning protection) that pertain to power quality at communications facilities and improve up-time. Proper wiring and grounding, beyond those minimal requirements of the NEC, can greatly alleviate power quality problems in broadcast and public service communications facilities. These improvements can be very cost-effective, usually simple in description, and help prevent costly downtime and equipment damage. The presentation concentrates on actual experiences at broadcast facilities where grounding and lightning protection were of paramount importance in maintaining system availability.

For several decades, the technological, bandwidth, and cost differences between television and radio made them two different electronic media. Information technology erases many of those differences. For example, IBOC has provisions for video while ATSC has provisions for radio, and IP has provisions for both. If broadcast engineering was separated into TV and radio in the past, this generation of engineers is divided between the over-the-air and content technologists. Broadcasting’s future is always bright and the nature of its creators, transmission, content and business plans constantly changing. There are practical things broadcast engineers can do for their stations and themselves, and some things broadcast engineers at some level already mostly know we can expect of the future.

We all went through the TV loudness discussion and regulations. How about radio and netcasting? Bob Orban will give a remote presentation to Chapter 36 about just this:
My main topic will be the relationship between the fairly recent ITU-R BS.1770 loudness measurement standard and non-television applications such as FM radio and audio-only netcasting: what “target loudness” is and how it applies to audio-only services. I will also briefly touch upon low bitrate compression artifacts and how things have changed with the widespread adoption of the MPEG4 HE-AAC codec.
Join us and learn something! It’s Wednesday, March 18, at 12 noon at iHeartMedia, 9660 Granite Ridge Road, San Diego. Orban will provide a light lunch. Members and guests welcome.
