IP Protocols for Audio and Video - A Networking Update. Presented by Frank Grundstein of Logitek. IP Audio Networks have become the accepted method for new facility construction. Video over IP is gaining traction fast. For Audio, we have the universally adopted AES-67 transport standard; the AES-70 not so widely adopted control protocol, but still no discovery protocol. For Video, there are, at this moment, an alphabet soup of 7 industry groups proposing various solutions for Video over IP. Where do we stand and how do we know what to do if we are thinking about a facility renovation? We’ll review the current state of IP for Audio and Video, see where the paths intersect and maybe find a Unified Field Theory for IP for broadcast.
Lunch will be provided by Logitek. When you arrive at Zarda proceed to the back room for lunch and the meeting.
Future Meeting Programs:
May 17: RF Specialties - AM Multiplexing
June 14: TBD

On February 8, 2017, Chris Childs of Satellite Engineering Group (SEG) gave a presentation to our SBE chapter on the AMC 8 satellite transition.
Here are his presentation slides:
He also supplied a link to another source of up-to-date information:
September 28th 1:20 PM central time.....that is the official date and time for the next National EAS test.
The FCC's Public Safety and Homeland Security Bureau has officially published notice that all EAS Participants are required to participate in the nationwide test.
In case anything arises to delay it (such as a real emergency, during which a test could cause confusion), a secondary test date is set for Oct. 5.
Items stations must take care before that date....
1. Make sure your EAS equipment is programmed with the new national location code of six zeros (000000). This new code covers every state and county in the United States and should be programmed with National Periodic Test (NPT) event code. Deadline to have the new code programmed is July 30th.
2. All EAS Participants must register with new EAS Test Reporting System. Click on ETRS registration page (you must have station FRN user name and password to enter this page).
You will be emailed a special user name and password for use to access the forms. You must file ETRS Form One by Aug. 26. Form two will be filed on the day of the test (September 28th) and form three must be filed by November 14th.
3. Check you EAS logs to make sure you are receiving the IPAWS Required Weekly Test (RWT) each Monday at 11:00 AM local time.
"The test message will clearly state that the alert is only a test of the EAS," the FCC bureau stated. "FEMA's alert will be transmitted in English and Spanish and include both audio and the text of the test message, which can be used to populate an accessible video crawl. These improvements will help ensure that all members of the public, including non-English speakers and individuals with disabilities, will receive emergency information.

At the regular chapter meeting in August, 2014, Perry Priestley of Anywave Communication Technolgies gave a presentation on DTV transmitter efficiency. Here are the slides from that presentation in PDF form:
At the May, 2014, monthly chapter meeting a new piece of legislation in the neighboring state of Oklahoma related to broadcasters and emergency situations was discussed.
The final version of the act can viewed on-line here:
Further research showed that a similar bill was being considered this year in Missouri:
The Missouri House Bill 1582 “First Informer Broadcasters Act” will have to be taken up this fall as the Missouri Legislature ended its session on Friday, May 16th (2014). The bill “establishes certification (for) radio and television broadcasters under the "First Informer Broadcasters Act" in order to prepare for and respond appropriately to an emergency or disaster.”
At the October, 2013, SBE meeting Kirk Chestnut mentioned a local organization that is involved in promoting science, mentoring, and hosts a city-wide science fair that is in need of judges/volunteers. Here is a link to their website:

At the monthly meeting on October 9, 2013, chapter member John Gray gave a presentation on quantum physics and the double slit experiement. Below are links to some YouTube videos on the topic presented by Richard Feynman.
Presentation from 1964 (worth it just to watch the intro):

At our April meeting chapter member Ed Treese brought in an item that was located in engineering storage at 1480.
It is made of rubber and has a small weep hole. So - what is it?
Chriss Scherer, CPBE CBNT, editor of Radio magazine, past president of the Society of Broadcast Engineers (SBE), and local SBE chapter 59 member paid tribute to the founder of the SBE and former technical editor of Radio magazine, John Battison (1915-2012), during the SBE's Awards Banquet at the 2012 National Meeting on Oct. 24, 2012.
