Mike Curran reports “I received a call from Jon Cook from Palomar Communications. He has received notification from the City of San Diego that the washed out road conditions on the road up to Mt. Woodson would be undergoing repair work starting on May 13th, and will last for approximately one week. These repairs will cause the road to be closed to all vehicular traffic. Accommodations for emergency engineering personnel to make repairs up on the mountain will be made by allowing us to park at the bottom of the hill and then be shuttled by golf cart up to the construction site, then the engineering staff will have to hand carry their tools over the construction site to another awaiting vehicle and be ferried up to the top of the hill to perform their duties. So the only thing you can get up to the mountaintop is what you can carry by hand.”

Regional Transmitter Site Copper Theft Continues

From the Southern California Broadcasters Association:

Two LA-based SCBA members have been robbed of all copper and copper connectors at their transmitter sites. Both crimes occurred within the past 30 days This was not the work of kids as all they were after was the copper, and knew to cut the video security cables.

L.A. police are not making this damage to a public service resource a priority, so we must.

If you have been robbed as well, please let us know ASAP.

If this is a ring targeting SoCal Radio station transmitter sites, none of our member sites are safe. If they are a ring, we want to escalate this crime to the FBI and the Mayor’s office. Having a number of break-ins makes our case for federal inspection, protection, and prosecution stronger.

San Diego is Done with 600 MHz TV Broadcasts

On March 26, 2019,

  • KVCR San Bernardino switched to channel 5 from channel 26
  • KSWB San Diego then switched to channel 26 from 19
  • KPBS San Diego then switched from channel 19 from 30

If you are an over-the-air viewer with a TV antenna rather than cable or satellite and you can’t receive some of the local TV stations, you will need to perform a RESCAN on your TV for the new channel lineup. Press your remote control MENU button and find the SIGNAL or ANTENNA submenu, then select AIR (not CABLE), then AUTOPROGRAM or SCAN or RESCAN. Not all TVs have the same menu titles, so you may have to consult your TV set owner’s manual. Yeah, sorry you threw that away. Check out YouTube, maybe.

Bonus March Chapter Meeting: SAS and Recent Digital Audio Protocols

While AES-67 Audio over IP and now AES-70 (GPIO and Control over IP) are popular in the radio broadcast world, a little known standard called IEEE-802.1 (also called AVB), is continuing to grow in the TV/Film, Production, Automotive and Consumer Industries. AVB (“Audio Video Bridging”) is an Audio over Ethernet (AoE) mechanism with auto QoS. With its growing popularity many other industries, the IEEE is positioning this technology to replace HDMI in entertainment systems, gaming consoles and TV Displays. AVB provides a mechanism for intuitive control and discovery. AES-67 is an Audio over IP (AoIP) topology, and while development is ongoing for “control and discovery”, (as is AES70), it’s poised to become the industry standard for radio broadcasting. We’ll outline key differences and typical applications for each protocol.
