This Week’s Newsletter

Greetings from your broadcast friends out on the Desert…
This is BDR Newsletter 771, Volume 15, #43 for May 22, 2024

Here are some things you might want to know about:

THAT CEM ERUPTION WAS REALLY A CME
It is hard to hide when your headline goes awry. Some sharp-eyed readers last week wrote in to remind us that it was actually CME – a Coronal Mass Ejection. Those solar flares – five of which reached Earth – caused auroras as far south as Alabama and disrupted HF transmissions for days.

Some scientists saw this as a dress rehearsal for when a larger CME happens, or an EMP hits the world, from natural or man-made causes. The debate over what level of disruption this will be caused is worth examination by everyone, including broadcasters. How much infrastructure will survive? The late Glen Clark looked into it in a well thought out five-part series.

IF YOUR EAS RECEIVER GETS NO IPAWS TESTS/ALERTS
Reports from around the country indicate more than a few stations still have yet to install the latest certificate to allow the IPAWS tests and alerts to be received. The change in certificates was in late April. Stations without the latest update are risking a potential fine should the FCC become aware (note: an on-site inspection is not required for them to issue an NoV).

FM TRANSMITTER NEWS
One of the big themes this year is the way companies are building more and more features into the transmission system, including new lines of lower powered transmitters. At NAB, WorldCast displayed the way they have reduced the count of separate units with their AiO transmitter line. For one thing, the codec decoder is built into the transmitter. This not only reduces complexity, but also costs.

Join with us to hear Tony Peterle from WorldCast discuss the new transmitter’s features including the APTmpx link. We will be live, as usual, Thursday at 2 PM Eastern / 11 AM Pacific. We hope to see you then! The link request is still at www.thBDR.net/TLG/
