MaxxCasting Co-Channel Translator

david

According to GBS MaxxCasting Expands KYLA-KYRA/L.A. Audience Reach KYRA-FM (LA north) and KYLA-FM (Fountain Valley = LA south) who simulcast on 92.7 FM have expanded their joint signal quality and audience reach through the installation of a broadcast translator in downtown L.A., increasing the listener reach by as much as four million.

If this is an option for connecting two co-channel signals to provide continuous expanded, seamless coverage then I hope KCSN and KSBR who are co-channels on 88.5 FM explore doing this as well to improve their signals and increase their listeners and drive ratings and donation revenue growth.

The article say MaxxCasting combines radio and cellular technology and enables FM Broadcasters to enhance their signals by reducing interference between the main and booster transmissions through the use of a cluster of low-to-the-ground, high power, highly directionalized, synchronized node sites. It claims the technology also allows for innovation in spectrum allocation, coverage problems and frequency acquisition.

And apparently, the tech allows for geo-fencing and targeted ads. 🤔
 
New technology allows them to get a more precise alignment on the timing between the booster signals and the main signals to control the interference zones. The MaxxCasting people also are trying to get approval to carry different content on each booster (targeted ads). It seems like the interference area would increase when they split programming.
 
I can see how this would work in the digital realm. But this is analog FM right? 1/2 wavelength is still about 60 inches. I can't see how there won't be destructive interference in the area where two signals are equal. The laws of physics still apply. And yes, two different programs (targeted ads) will essentially mean two non-coherent signals, which makes things even worse. The new DSP receivers and diversity antennas on some vehicles will definitely help, and chances are the overall coverage will increase. But definitely not like a single, high-powered signal.

This is something I've always wanted to try with all-digital though. Even on AM. I bet it would work.

Synchronized transmitters on AM has already been proven successful. They too have an interference zone, but much smaller
