November 15 Meeting: Caig Labs

One of the biggest causes of grief for any broadcast engineer has been corrosion of dissimilar metals and its effect on circuits that are supposed to conduct. We’re talking switch contacts, insulation displacement contacts, and connectors of all kinds. Caig Labs, based right here in Poway, has made chemicals for treating contacts with anti-corrosion and lubricating qualities for some time. What goes into these products? Which ones are right for which problems? How did Caig Labs get started?

Join us at Wednesday, November 15th at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego as Jimmy Hong of Caig Labs gives us a presentation. We’ll provide a simple lunch.

Jimmy Hong has been with Caig Labs as a Sales Rep. for a year, servicing retailers, repair and maintenance shops, and OEMs.

October 18th Meeting: Wheatstone HD Audio Alignment and Other Tricks

Keeping your FM station’s IBOC digital audio time-aligned with your analog audio has been a source of frustration since digital was introduced. At one time, this meant manual adjustments until you could no longer perceive the difference, perhaps using a headphone with one stereo side in digital and the other in analog. Then along came separate boxes to attempt alignment, but that introduced another single point of audio failure into your system.

Wheatstone’s Mike Erickson, one of the country’s most renowned processor experts, discussed at our October 18, 2017, meeting the AirAura processor and how it addresses HD time alignment and other FM challenges with a correction input from a Belar monitor. We also discussed processing as it relates to the reduction of FM multipath.

In Chapter 36 business, we discussed the recent survey and how it related to occasional low meeting attendance. Officer elections are next month. It’s a good time to step up and try your hand at leadership positions. Contact Gary Stigall.

About Mike Erickson

Since 2010 Mike Erickson has been Wheatstone’s system and support engineer for their line of broadcast and studio processors. Before working at Wheatstone, Mike spent 15 years at CBS New York, the last 4 years as the chief engineer of WCBS FM.

September 20 Meeting: Ground is a Myth!

Ground is something you stand on, but in an electrical sense, the meaning is much less clear. When it comes to broadcasters and ground, things get really confused. We drive rods into the earth, but why? Let’s take a look at whether any of this makes sense, and what theory tells us about “ground”, and if it exists in any sensible way at all. We’ll talk about DC grounds, RF grounds, and even about gravity.
Join us Wednesday, September 20th, 2017 at noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Chapter 36 will provide pizza for this great lunch ‘n’ learn session.

Using Drones in Broadcast Operations

Drones, or unmanned aerial vehicles, are useful in several broadcast operations, including ENG, tower inspections, site documentation, signal measurements, and even training videos. During this hour and half webinar, we will explore these uses and discuss FAA requirements, including how to get your Remote Pilot license, and some of the challenges and opportunities drones can bring to your stations. Sam Wallington, vice president of engineering, Educational Media Foundation (K-Love/Air) presents on Thursday, October 19, 11:00 AM to 12:15 PM PDT.
