Dennis Younker Retiring from Long Career at Cox Communications

If you’ve been in TV broadcast engineering management at any time over the past 27 years, you’ve had the pleasure of working with Dennis Younker, Cox Communications Headend Manager, regarding getting your signal on cable TV. He’s told you if you had issues with color, lip-sync, signal dropout, and even digital drift or jitter. In other words, he’s had your backside. After 43 years in the business, he’s hanging up his keys and will be doing exactly what he wants to from now on. Dennis sat down and wrote this memoir about the cable business and his part in it for SBE 36. Enjoy.

Q: You were hired to lead the Engineering Department at KNSD though you had come from a non-broadcast background, right? That speaks highly of your impressing the hiring staff. What had you done before taking that job?

A: I worked for the Dept of Defense. This was my first job in TV. I had to learn a lot very quickly, but I was helped by an amazing team at KNSD, an industry changing to look more like IT, and similarities between broadcast and DoD standards.

KWFN 97.3 Pioneers New FM HD Booster Network

Entercom San Diego, through technical consultants GEO Broadcast Solutions, has built out a significantly advanced Single Frequency Network (SFN) for their 97.3 MHz station, KWFN (FM), “The Fan.” The team added analog-digital hybrid Xperi HD Radio on February 19, 2020 to help KWFN reach an audience that now extends past some significant terrain barriers within their licensed service contour. KWFN, with its sports talk format, hosts the current Padres Radio Network. The SFN includes the booster KWFN-FM1 La Jolla (in the Bird Rock neighborhood), KWFN-FM2 Ramona, KWFN-FM3 San Marcos (from Whitney Peak), and KWFN-FM4 Escondido (from Black Mountain). GEO is working to add the KWFN-FM5 booster in Encinitas that they have an FCC Construction Permit for.

The FCC Wants Comments on “Franken-FMs”

The Media Bureau of the FCC issued a Public Notice last week seeking comment on whether channel 6 analog LPTV stations should be able to continue to operate after the deadline to switch to digital.

Even after the 2009 TV broadcast transition to digital, the FCC allowed LPTVs to continue to broadcast in analog until 12 months after the completion of the post-incentive auction repack, due for a July 3, 2020 completion. This means LPTVs would have to make the digital switch by July 3, 2021.

This aural service on TV channel 6 has taken the pejorative term “Franken-FM” due to the distorted analog TV broadcast technology that boosts the power of the FM aural carrier, increases the modulation, sets the pre-emphasis to match that of the FM broadcast band, and usually runs a video slide show or fixed graphic in the visual portion of the signal. This is all done to add an FM station to the market. Venture Technologies, based in Los Angeles, has placed these stations all over the country, including KRPE-LP in San Diego, on Mt. San Miguel. Most home and car radios can receive this signal on 87.75 MHz, and such stations generate marketing materials promoting “87.7 FM.” Venture Technologies leases its signals to third-party programmers.

Comments must be in to the FCC 45 days after the comments solicitation is published in the Federal Register.
