Tonight is the bimonthly SBE HAMnet that originates in Denver but broadcasts on Echolink for everyone to listen/participate.
We hope to have this linked into our repeater soon but for tonight join them on Echolink.
The SBE IRLP (Internet Repeater Linking Project) HAMnet is today (Monday), at 9 p.m. US ET (6 p.m. US PT) and worldwide via IRLP reflector 9615.
The SBE IRLP HAMnet uses the Denver-based N0PQV repeater 145.340, IRLP node #3350. The SBE IRLP Reflector, Node 9615, is now connected to the world via Echolink using a computer as well as via radio. This reflector is also connected full time to the WA2CBS repeater in New York City.
Broadcast TV antenna manufacturers should make some good sales numbers in the next couple of years as the FCC forces broadcasters to shuffle channels again. This time around, the emphasis will be on broadband designs. Jampro has been working to make their antennas work on multiple channels with minimal wind loading. Many broadcasters will be looking at designs that make the best use of ATSC 3.0 as well. There are things to keep in mind you as broadcast engineers may not have considered, like OFDM Crest Factor and circular polarization for mobile coverage.
As a bonus, they plan to talk about their experience in Singapore with DVB-T2 and Single Frequency Networks.
Join us March 15 at 12 noon at KGTV, 4600 Air Way near I-805 and CA-94 in San Diego for the Chapter 36 regular monthly meeting. Jampro is buying lunch in the cafeteria.
The FCC last week issued a Notice of Proposed Rulemaking that would give TV stations the right to use ATSC 3.0. This was made in response to a petition made in April 2016 by a consortium of Public Television, NAB, the Consumer Technology Association, and the AWARN Alliance.
There are several catches, however. One would require stations to continue broadcasting in ATSC 1.0 as they do now. The other is that manufacturers would not be required to produce equipment that could be used to decode the signals. The likelihood that broadcasters would use the technology is near zero, especially due to upcoming TV spectrum repacking that will use all available bandwidth in just about every market. A third hurdle is that consumers would have to bear the cost of converting the ATSC 3.0 signals to something usable with present TV sets.
Broadcasters and manufacturers will have an opportunity in the coming months to comment on the NPRM.
The Enforcement Bureau imposed a forfeiture order of $25,000 against Nelson Quintanilla for operating a pirate broadcast station on 95.1 MHz in Panorama City.
They also imposed a monetary forfeiture of $25,000 on Iglesia el Remanente Fraternidad Elim, Inc. and Belarmino Lara for operating a pirate radio station on 93.7 MHz in Arleta, near the intersection of I-5 and CA-118.
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.
About the Presenter
Tony Spica recently joined Audio Precision after nine years with Bruel and Kjaer as an Application Engineer and Solution Manager. He is based in Los Angeles where he has lived and worked for the past eight years. Prior to joining Bruel and Kjaer, Tony worked as a NVH Engineer developing test systems to detect defects in automotive parts through sound and vibration signatures in Detroit, Michigan.
General Manager Chuck Dunning told a teary-eyed station staff Wednesday, January 25, that the San Diego’s CW6 News Department would stop operations on March 31. Further, he said, they would end the CW affiliation and close the Kearny Mesa facility May 31 this year. At that time, XETV Tijuana will begin relaying Canal 9 from Mexico City.

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:
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.
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.
KFMB hired two Broadcast Maintenance Engineers in November.
The AM/FM/TV combo hired Julio Ramirez, previously with the Signal Wiz contract engineering company assisting with maintenance at KPRI (FM), KSDY-LD, and other clients. More recently, he had done IT work at XETV for Paul Redfield’s Orbdot contracting services company, and tech support for ESET security software. Julio enjoys music and photography after hours.
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.
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.
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.
