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, discussed at our September chapter meeting 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.
Many thanks to GEO Broadcasting Solutions and the attendees who made this meeting a great success.
