September Meeting – Single Frequency Networks for Radio

You should be able to drive around our terrain-challenged media market and receive excellent FM broadcast reception everywhere. Till now you haven’t been able to because of signal shadows and multipath. GEO Broadcast Solutions has been working on this throughout the nation and this year has been helping Entercom’s KWFN (FM) locally extend their 97.3 MHz signal through a series of boosters extending their coverage into northern San Diego County. The science of this is more complex than you might imagine; boosters have to be in-phase to the digital bit to work effectively. How do they do that?

Bert Goldman, advisor to GEO Broadcast Solutions, will give a talk at our next chapter meeting on the science and implementation of what they call “Maxxcasting™,” SFN’s for FM broadcast transmission. They’re also working on a related technology, “ZoneCasting™” that could allow geographic targeting of ads within Maxxcasting™ regions.

Join us Wednesday, September 18th at 12 noon at iHeartMedia, 9660 Granite Ridge Drive. We’ll provide a lunch and give Bert the floor for this important presentation.
