KFMB’s “Quadzilla” Being Replaced This Week

Crews are working this week at the KFMB-TV transmit site on Mt. Soledad to swap out the 8-bay multi-station Dielectric FM transmit antenna for a new 12-bay Dielectric. After the current group of sharing stations moves to the lower power Dielectric aux antenna Monday, June7, Wireless Infrastructure Services will disassemble the ERI antenna known as “Quadzilla.” They’ll replace it with the 12-bay, 1/2-wavelength spaced Dielectric antenna designed to handle the greater power that will be needed to handle the addition of three more full-power stations.

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 new 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 will also move from KGTV to KFMB-TV, but their allocation requires a separate, directional antenna to be mounted on a tenant tower at KFMB-TV. The signal has some reduction in signal toward Mexico to the southeast. 

he 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.

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.

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.
