Loudness Control. Bob Orban will deliver a presentation that will cover Orban’s approach to automatic, CALM-Act-compliant loudness control as embodied in the Optimod-TV 8685 Surround Loudness Controller, and will discuss the features of the 8685 in detail. He will discuss how Orban combines the CBS Technology Center and ITU-R BS.1770 approaches to obtain the advantages of both. It will cover the concept of “genre” in the context of BS.1770, as first introduced in a 2015 AES Recommendation, and how taking genre into account can reduce some of the practical objections that have been raised as a result of experience with normalizing all program material to the same BS.1770 target loudness. He will also present measurements showing the effectiveness of Orban’s approach.
Lunch will be provided by Orban. When you arrive at Entercom, proceed to the lobby on the second floor from which you will be directed to the meeting location.

National EAS Test Update (2016)
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….
- 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.
- All EAS Participants must register with newEAS 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.
- Check you EAS logs to make sure you are receiving theIPAWS 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.

Oklahoma First Informer Broadcasters Act
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:
