February 15 Meeting: Audio Precision and the Noise Floor

How Low Can You Go?

What are the capabilities of modern test equipment and its ability to test very low noise and distortion devices? Can test equipment of today keep up with increasingly impressive specs? Are the specs real? We’ll review some real world examples from both the electrical audio test world as well as room acoustics testing.

Join Chapter 36 Wednesday, February 15, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Audio Precision buys lunch. Members and visitors are welcome as always.

What Bob Gonsett Says About Loss of Bay City Television

Bob Gonsett, a well-known broadcast engineering consultant who counted among his clients XETV Tijuana, said this about the announced closure of their San Diego office:

Early XETV screen logo

XETV not only had the best channel to cover San Diego from a propagation standpoint, it also had a rich history of being technologically first in a number of important areas including the use of circular polarization which significantly improved indoor “rabbit ear” reception.  Station management in the U.S. was constantly striving to make XETV Number One and they made the funds available to do so. The Tijuana transmitter plant, run by Felipe Fernandez, was a meticulous operation in full compliance with SCT/FCC mandates and from a labor perspective,

Phil always advocated the very best for his engineers. He was a true father to many. It was an honor and privilege for me to work with XETV for decades as their FCC engineering consultant.

January 18 Meeting: LTE for Broadcast by Moseley

Sumit Singh of Moseley discusses LTE technology for broadcast microwave news at KFMB-TV.
Sumit Singh of Moseley discusses LTE technology for broadcast microwave news at KFMB-TV.

An attentive crowd at the KFMB studios heard Sumnit Singh make a case for using the technology developed for consumer mobile devices to relay news audio and video to broadcast outlets over private networks. It should be interesting to see if stations step up to the plate to capitalize this evolution, or if an organization will step up to finance the movement and then resell to broadcasters, or if the technology will die on the vine before being rolled out.

Many thanks to Sumit Singh for traveling to San Diego and for buying our lunch. Continue reading January 18 Meeting: LTE for Broadcast by Moseley

KFMB also hired Joseph Pandolfo, past Chief Engineer at each KMIR Palm Springs, WTXL Tallahassee and WDBD Jackson. He had also served with Harris Broadcast as server product field support engineer. He’s been a member of SBE since 1984 and has a CBNT certification.

FCC Catches Up to LA Area Radio Pirates

In early December, 2016, the FCC issued a Notice of Apparent Liability, proposing a $25,000 fine for Iglesia el Remanente Fraternidad Elim in Panorama City in the San Fernando Valley of Los Angeles. That church has operated a radio station on 93.7 MHz while repeatedly ignoring FCC requests to shut down since 2013. In fact, the website continues to publicize the FM pirate station.

In a second Panorama City church pirate radio case, field agents traced a signal at 95.1 FM back to an antenna atop the Ministerio Internacional Luz A Las Naciones church after they received complaints about the station in March 2015. They warned the property tenant, Nelson Quintanilla, that his continued unlicensed operations could lead to more than a warning. But the station remained on the air despite repeated warnings to Quintanilla—who at one point admitted to agents he was responsible for the station. The Enforcement Bureau says when agents returned to the church in October 2016, the station was broadcasting again. They are also proposing a $25,000 fine for this case.

SBE 36 Holiday Luncheon at Mimi’s Cafe in Mission Valley, December 2016.

The SBE gang held its annual holiday luncheon this year at Mimi’s Cafe in Mission Valley and had a great time of it. Congratulations to those who walked out with prizes. Nigel Worrall received a ham radio handi-talkie from RF Specialties. Bob Gonsett, Steve Frick, and Barbara Lange walked off with chocolates or wine from Piper Digital and Utah Scientific. Everyone got great food and conversation.

SBE Chapter 36 Gets UHF Amateur Radio Repeater

Mt. Soledad in La Jolla is now home to another radiator, KI6KHB/F. A new Yaseu Fusion repeater is broadcasting on 445.540 -. It is in Auto mode meaning if you transmit FM, the output will be FM. If you’re using the digital C4FM mode, the output will be in C4FM.

Frequency: 445.540 -, PL 88.5Hz, DSQ code: 36

Repeater output is 25 watts TPO on a station master omni antenna right above the roof line at the KGTV site.

Note: This repeater is coordinated with SCRRBA and is co-channel with the WB6AJE repeater on Mt. Wilson in Los Angeles. Outside Oceanside there may be overlap between the two machines so we’re suggesting only use the repeater if within the county.

Local broadcast engineers are encouraged to use the new repeater.

Huge thanks to Chris Durso, Gary Stigall, Bob Vaillancourt, John Bush and many others that made this year long project a reality.

KURS Sold to El Sembrador Ministries

KURS 1040 kHz AM San Diego
KURS 1040 kHz AM San Diego

RadioInsight.com reported last week: “El Sembrador Ministries is exercising its option to purchase silent 1040 KURS San Diego CA from Quetzal Bilingual Communications for $900,000. El Sembrador is being credited half of its time brokerage fees paid since July 2014 subtracting $310,000 from the money owed. KURS went silent in early October after failing to pay tower owner Multicultural Broadcasting due rent. $10,816 from the deposit paid to Quetzal will go to Multicultural to restore the station’s use of the tower.”

In June this year, the FCC issued a $12,000 monetary forfeiture and short-term renewal for KURS(AM) for failure to prepare issues and program’s lists in the Station’s public file and to file biennial ownership reports.

The same station was issued a Notice of Apparent Liability for violating output power limits in June 1999.

Jaime Bonilla, associated with Quetzal Bilingual Communications, also owns group Media Sports de Mexico stations XHPRS Tecate (operated by Broadcasting Corporation of America as Max 105.7), XEPE 1700 kHz (also operated by BCA), XESDD 1030 kHz Tijuana, and XESS 620 kHz Rosarito, Mexico. XESDD was noted by local engineers for its dial position only 10 kHz away from co-owned KURS, less than 20 miles away.

New Tijuana DTV Station on Channel 33

A new DTV signal appeared last month on physical channel 33.  An informed source says the signal is from XHCTTI on Mt. San Antonio in Tijuana, virtual channel 3.1 broadcasting the new network Imagen, meant to compete directly with the dominant Azteca and Televisa networks.
