Investment private equity firms Standard General and Apollo Global Management announced last week they are jointly purchasing broadcasting holding company TEGNA for $5.4-billion. The purchase will include San Diego CBS affiliate KFMB (TV), which had been picked up by TEGNA in late 2017.
Standard General previously led Young Broadcasting out of bankruptcy, with the company acquiring a controlling stake in Media General, which sold to Nexstar in 2018. Apollo, meanwhile, owns the TV stations that had been operated by Cox Media Group, having acquired them in 2019.
Audacy-owned KNX Los Angeles, known for its all-news radio format since 1968, began last week broadcasting on KNOU (FM) 97.1 and identifying itself exclusively by its FM channel location.
KNOU (FM) is licensed for 21 kW from Mt. Wilson with a directional antenna aimed southwest, so its signal toward most of the LA basin is compromised, but given its elevation, it still covers the region well.
With cars increasingly leaving out AM tuners (looking at you, Tesla), and with the superior fidelity of FM, the move could help boost listenership. Other Audacy all news outlets, such as KCBS San Francisco, WBBM Chicago, and KYW Philadelphia, now simulcast on FM stations.
The Society of Broadcast Engineers, the association for broadcast and multimedia technology professionals, announces the results of the 2021 election for the national board of directors. Andrea Cummis, CBT, CTO, was elected as the society’s president. Cummis is the chief technical officer of PBS39/WLVT-TV, in Bethlehem, PA. She is the first woman to be elected to hold the office. She is a member of SBE Chapter 15 in New York City.
Regarding the election, President-elect Cummis said, “I look forward to serving the Society and its members. President Wayne Pecena has led the society through an interesting and unusual time, and as everyone looks forward to a return to normal, I’m pleased that the society is still growing and thriving. I’m eager to work with the Board of Directors and the membership so we can expand our membership and outreach to the media professionals among us.”
DASDEC and One-Net Users Must Update Certificate Before Aug. 21 to Maintain Proper Operation
LYNDONVILLE, N.Y. — July 20, 2021 — Digital Alert Systems, the global leader in emergency communications solutions for video services providers, today announced the availability of an important update of Federal Emergency Management Agency (FEMA) digital certificates used to authenticate messaging from the Integrated Public Alert and Warning System (IPAWS).
The company has released updated IPAWS Certificate Authority (CA) credentials for the DASDECTM and One-NetTM series of Emergency Alert System/Common Alerting Protocol (EAS/CAP) encoder/decoders to replace a certificate in the current certification chain that will expire on Aug. 21. All U.S. DASDEC and One-Net users are advised to replace the soon-to-expire certificate to ensure the required message authentication continues to operate properly. Digital Alert Systems reminds all EAS participants the FCC requires them to “configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature.”
“With just a few weeks to go, we urge DASDEC and One-Net customers to update their certificate files before Aug. 21 to prevent any disruptions,” said Adam Jones, senior sales engineer for Digital Alert Systems. “While this seems like an annual occurrence, our customers will be pleased to know this new certificate is good until April of 2024!”
Digital certificates, called CAs, are used by FEMA to create a chain of trust between an EAS device and the IPAWS servers. The DASDEC and One-Net EAS/CAP devices use these special digital certificates to validate the authenticity of IPAWS-sourced CAP alerts. These certificates are designed to expire on a specific date and time, requiring the issuing authority to publish new certificates as replacements.
All DASDEC and One-Net customers using the IPAWS system must have the latest certificates in place so only messages authenticated through IPAWS are processed. IPAWS users who do not update their equipment before Aug. 21 could see this error message: “Event Log: Digital Signature
VERIFICATION ERROR: Signer UNTRUSTED! Check for correct CAP decoder CA file.” Alternatively, the device might simply ignore valid IPAWS alerts.
The new field service bulletin and CA file are now available from the Digital Alert Systems website at www.digitalalertsystems.com/DAS_pages/resources_fsb.html. DASDEC and One-Net customers should go to the website, download the field service bulletin for instructions, and link to the new CA file.
