KUMI (FM) Relinquishes License

Activist San Diego (“ASD”), licensees of a new non-comm FM station, KUMI 89.9 Romona, sent a letter to the FCC dated July 19, 2021 responding to an earlier FCC letter asking for clarification regarding whether the station had ever been on the air.

Acting General Manager Martin Eder said in the response that they had offered to transfer the license to the Los Coyotes Tribal Chairman’s Association but “heard nothing in return.” Eder did not state whether ASD had actually ever installed or operated a transmitter in spite of having claimed to have been on the air since July 2019 and having held a current license.

Eder told the FCC that ASD “voluntarily relinquishes our FCC broadcast license for 89.9, Romona, CA hoping to serve the greater good.”

The FCC canceled the license July 24, 2021.

Digital Alert Systems Issues New FEMA IPAWS CA File to Replace Expiring Certificate

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.

Sage ENDEC Offers Firmware Update

Sage Alerting Systems has announced that the Sage Digital ENDEC model 3644 users should concern themselves with two upcoming events:

FEMA Signing Certificate updates (CR-Rev6)

A signing certificate used by FEMA to validate CAP alerts will expire on Aug 21, 2021 at 21:00:00 UTC. Sage has released a free firmware update for Rev95 that you must install to permit your ENDEC to continue to receive EAS CAP alerts from FEMA after that date. You can install the CR-Rev6 update at any time before August 21, 2021. You do not need to install it before the National Periodic Test as the NPT will not use CAP this year.
Please go to the Sage firmware update page at https://www.sagealertingsystems.com/support-firmware-new.htm to read the release notes and download the update file. You must already be running the Rev95 release to install this update.

National Periodic Test (NPT)

This year’s test will be sent via the Primary Entry Point (PEP) network, that is, via over-the-air audio-EAS only, on August 11, 2021 at 2:20p.m. EDT. CAP will not be used. To help ensure that you will receive and relay this test, take the following steps:

1) Check your log to make sure that you are receiving weekly tests from your monitor assignments, and that you have been originating weekly tests and relaying Monthly Tests as required by your license type.

2) Make sure your ENDEC has a filter to receive and relay the NPT. The easiest way to check this is to access your ENDEC with a web browser. From the main page, click the Tools button on the left column, then click the “Verify Req” button. If you see “Your ENDEC will meet the FCC requirements for the National Periodic Test” on the last line, your ENDEC is ready.

If you have any questions regarding this update or the NPT, please email us at support@… or call 914-872-4069 and press 1 for support. If you get voice mail, please leave a message and we will call you back.

FM Stations Finish the Great Mt. Soledad Antenna Swap

[Updated July 18, 2021] Crews working at the KFMB-TV transmit site on Mt. Soledad last month replaced the 8-bay multi-station Dielectric FM transmit antenna with a new antenna. The current group of sharing stations switched temporarily to the old aux antenna Monday, June 7. Then, Wireless Infrastructure Services disassembled the ERI antenna known as “Quadzilla.” They replaced it with a new 12-bay, 1/2-wavelength spaced Dielectric antenna designed to handle the greater power from the three moved from neighborhood transmitters. 

The FCC in late February and early March granted Minor Modification applications for all of the iHeartMedia FM stations atop Mt. Soledad to consolidate at the historic KFMB-TV site, moving from KGTV’s antenna across the street. iHeart’s KMYI 94.1 and KIOZ 105.3 will join current master FM antenna partners KPBS-FM 89.5, KBZT (FM) 94.9, KXSN (FM) 98.1, and KFBG (FM) 100.7. EMF’s KLVJ (FM) 102.1 Encinitas has taken delivery of a Nautel GV15 transmitter and will move its signal from the UCSD tower site to the new master FM antenna, as well. 

iHeartMedia’s KSSX (FM) 95.7 Carlsbad moved from KGTV to KFMB-TV, but their allocation requires a separate, directional antenna that was mounted on the tenant tower at KFMB-TV. The signal has some reduction in signal toward Mexico to the southeast. Last week, Vic Soelberg installed the new Dielectric antenna. 

All the stations on the KFMB-TV site fired up their transmitters at full power during the week of July 11–17, the last ones late in the week after an air conditioning upgrade was finalized.

The FCC granted a Minor Modification application for iHeart Media to move K277DH, the KLSD (AM) translator on 103.3 MHz, from a KGTV-owned tower to the KFMB-TV tower. The CP specifies a vertically polarized Kathrein yagi with an east-west orientation at 250 watts ERP. 

Since the KFMB Stations were sold to TEGNA, InSite had been managing the site for income. American Tower Corp. recently acquired all of the InSite properties and management contracts and has taken over management of the KFMB-TV property.

Chapter 36 Calls a July Beach Party

Says Chairman Anthony McDaid, “It’s been 15 months since Chapter 36 had an in-person meeting. so I thought it would be nice to have a day at the beach as a way to socialize and find out what everyone has been up to during that time.”

“Please join us July 30th at Mission Bay. Pizza and drinks will be supplied but feel free to bring your own. Parking is nonexistent so best to ride share. Meeting point is 815 Coronado Court, 92109. I will be there from 12:00 noon and will have an easy-up and some chairs already set up on the bay side nearby.”

If you can’t find parking on Mission Boulevard, consider parking at the public lot across Mission Blvd. from the Belmont roller coaster, then walking the quarter mile to Coronado Court.

You’re welcome to bring your significant other. No presentations, just sun and conversation.

Sounds like a good time to celebrate the opening up of COVID protocols. See you there!
