Re: [IRCA] Two Thoughts About IBOC



A station can increase coverage by increasing modulation percentage, changing the spectral distribution to match the frequencies that most affect people’s judgments of whether a signal is good or bad, making the antenna more efficient, etc.

 

Where is your proof that CAM-D decreases coverage? Yours would be the first claim that CAM-D decreases coverage, so some real proof from you will be necessary.

 

As for digital broadcasting reducing coverage, it sounds like you don’t have experience with the required signal to noise ratio needed to demodulate many digital signals. If IBOC ever gets to the pure digital mode (as opposed to the hybrid mode), the transmitted power needed to match today’s analog coverage will be about one tenth that of the analog power.

 

I believe you confuse hybrid broadcasting of analog + digital with pure digital broadcasting.

Chuck,

 

Leonard Kahn is obviously LYING. The only way a station can increase coverage area is by increasing power. C-QUAM AM Stereo has never been proven to decrease coverage, unlike both CAM-D and "HD Radio". C-QUAM AM Stereo is already capable of CD-quality sound, along with FM Stereo. We don't need digital signals on the AM or FM bands; the only place for digital radio is via satellite.

 

Kahn lied about the "advantages" his AM Stereo system had over the far superior C-QUAM format. The truth to the matter is that DIGITAL BROADCASTING REDUCES COVERAGE. This is true with KFUO 850; they used to be heard at the Lake of The Ozarks with a good signal; they're lucky to make it past Warrenton now. CAM-D will not increase AM coverage areas, unlike a power increase.
