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 From:
irca-bounces@xxxxxxxxxxxxxxxx [mailto:irca-bounces@xxxxxxxxxxxxxxxx] On Behalf Of N0UIHEric@xxxxxxx 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 73, Eric (N0UIH) |
