National EAS Test Resuming This August

The National Periodic Test, not conducted last year during the heat of the pandemic, is scheduled for Wednesday, August 11, 2021. The transmission will be through the network of PEP (Primary Entry Point) stations—not through the IPAWS network.

San Diego County Stations can validate the NPT using their normally assigned LP sources, like LP-1 KOGO 600 kHz and LP-2 KLSD 1360 kHz. Additionally, KPBS 89.5 MHz is considered a PEP station by virtue of its affiliation with NPR. SiriusXM Radio has also been authorized as a PEP source. But you don’t need to reconfigure your system to confirm the National Periodic Test if it’s working for normal RWTs and RMTs.

SBE Online Presentation: All About WebRTC by Comrex

When Apple, Google, Microsoft and Mozilla team up, you might think, “Nothing good is going to come of this.” You’d be so wrong. An Open Source project is typically the last thing these tech behemoths would ever want to be involved in, let alone with their fiercest rivals. WebRTC is a fascinating example of how good things can be born of necessity and how they can foster cooperation on multiple levels. We’ll discuss the basics of WebRTC and the multitude of applications that are already using it to change the way the world communicates.  This is especially important in light of the rapid evaporation of our “traditional” telco infrastructure. We’ll also cover broadcast-specific applications and the future of live content creation.

SBE members and guests are welcome to join us online Tuesday, June 8, 2021 at 6:30 PM PDT/AZT.

Register in advance for this Zoom meeting here.

After registering, you will receive a confirmation email containing information about joining the meeting.

Stations Should Note Reason for IPAWS April 26 RWT Failure

When FEMA issues an IPAWS test or alert, it includes a “signature certificate.” This operates similar to a password for accessing different sites or files on a computer. In the case of a message from FEMA, a message without a correct signature the EAS device should ignore the message.

On April 26, 2021, the Required Weekly Test (RWT) from IPAWS was transmitted with an incorrect signature. The test messages had a mismatch between the digest inside the message, and the digest computed by receivers. This is a part of the validation for an alert, and checking it is required by FCC Rule 11.56(c): “EAS Participants shall configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature.”

Laszlo “Les” Zoltan Passes Away

We learned last week that the owner and CEO of DVEO in Ranch Bernardo, Laszlo “Les” Zoltan, died of complications of COVID-19 on January 30 this year.

According to his San Diego Union obituary, he was born in Hungary to Holocaust survivors, but they escaped to Canada when he was nine years old. Les graduated from the University of Waterloo with a degree in Electrical Engineering. After working at Tektronix for two years, he obtained a Master’s in Business Administration Degree from McGill University. In the U.S., he created Computer Modules, Inc. in 1982, selling industrial boards for PCs. Later under the name of DVEO, he sold video processors, converters, and streaming devices, as well as satellite receivers.

Les and DVEO supported SBE Chapter 36 as a sponsor and he was a part of the local broadcast community.
