November 20 Meeting: IP Networking Fundamentals with IEEE/BTS

This month we have the honor of being invited to share a meeting with the Broadcast Technology Society of the IEEE San Diego Chapter.

Wayne Pecena

Wayne Pecena, the current President of the SBE and a talented teacher, will lead a session on networking for the broadcast plant.

This presentation will review IP networking fundamentals and underlying standards to focus on the implementation of Ethernet switching and IP routing. “When to route and when to switch?”–that is the question. Theoretical concepts will be presented with considerations for network performance, security, and management utilizing practical implementation examples in a broadcast plant IP network.

Join us and the IEEE on Wednesday, November 20, 2019 at Advanced Test Equipment Rentals, 10401 Roselle St., in Sorrento Valley, San Diego. Networking, food, and refreshments start at 5:30 PM. The presentation starts at 6:00 PM and is expected to last about 90 minutes. This is an evening meeting.

The meeting is free for SBE and IEEE members, $5 for non-members. Everyone is welcome.

RSVP to Murat Karsi, BTS San Diego Chapter Co-chair at

DASDEC EAS Users Can Update IPAWS Certificates

From the SBE EAS List server:
If you are using a DASDEC or OneNet CAP EAS device, we received confirmation from FEMA to release the new Federal Bridge certificate bundle to our users.  Please try to have this certificate update file installed by November 8, 2019 – it is important for the proper validation of CAP alert messages from IPAWS.

The new FEMA IPAWS Certificate for DASDEC/One-Net is now posted: Instructions and download link for the bundle are found at that site.

Preventative Electrical Outages Take Down Local Radio Stations

Determined not to be blamed for fires due to sparking transmission lines, San Diego Gas & Electric has been turning off electricity prophylactically as Santa Ana winds build in northern and eastern San Diego County. Better to turn off power than have power lines spark in the wind, the theory goes. Outlying radio stations have gone off the air because of it.

We have reports of these radio stations leaving the air October 24 and 25:

  • KYDO 96.1 Campo
  • KKLJ 100.1 Julian
  • KWFN-FM2 97.3 Romona

KPRZ 1210 kHz San Marcos was reportedly able to stay on the air with a generator.

The FCC issued a Public Notice announcing the activation of a voluntary Disaster Information Reporting System in response to shutoffs by California electrical utilities PG&E and SDG&E. They are asking affected FCC licensees to report outages to the Disaster Information Reporting System (DIRS) at Of course, you’ll need to register with a User ID and password.

The FCC is asking communications providers to report outages from now until “DIRS is deactivated.” San Diego County is included in the “counties of interest” list.

FCC Considers Eliminating Old Rules Regarding Site Sharing

Let’s say you got in early–1949 perhaps–and you now own a highly-regarded communications site on a prominent location where no one else can develop a similar site. Let’s set as a random example, Mt. Soledad in La Jolla, California.

Should you be required by law to share that site with your competitors?

The FCC said so at the end of World War II, 1945, and that rule has remained in effect. And now they’re asking for comments on eliminating it.

Should they? On one hand, there are many more communications sites now to choose from. The likes of American Tower, Crown Castle, InSite, and Vertical Bridge are ready and waiting for you.

On the other hand, sites like Mt. Soledad will remain, as the FCC terms it, “peculiarly suitable for broadcasting.” What’s to keep Scripps and Tegna from excluding Entercom and iHeart from their sites at the end of their leases once the rules are changed?
