Dang That's A Great Idea ! - seems like I read it before . . . RHF

Expanding the FM Radio Band from 76 MHz to 88 MHz
http://groups.google.com/group/rec.radio.shortwave/msg/93586e2bf667afb2
Expanding the FM Radio Band from 76 MHz to 88 MHz
would give an additional 12 MHz of Radio Spectrum for
60 More FM Radio Channels. Using the TV Spectrum
from the former Analog VHF Channels 5 and 6.
.
Point # 1 - Why Not - Expand the FM Band !
Yes "HD" Radio makes sense in an "Expanded"
FM Radio Band to cover 76 MHz to 88 MHz to
create and additional 60 Channels for many of
the AM/MW Radio Stations to Transition to . . .

.
For the current IBOC Broadcast 'Scheme' to work on the
AM/MW Radio Band : The current Channel "Spacing" of
10 kHz would have to be expanded to 25 kHz.
http://groups.google.com/group/rec.radio.shortwave/msg/20a7d4e83ffae181
Meaning that Half the Current AM/MW Radio Stations
would have to be 'transitioned' from the AM/MW Radio
Band to the FM Radio Band. In order to accomodate
these 'new' FM Radio Stations; the FM Radio Band would
have to be Expanded by using the former Analog TV
Channels 5 & 6 {76 MHz to 88 MHz}.
.
What Is Required Is - An Expanded FM Radio Band that uses
the old Analog TV Channel 5 & 6 Frequency Range 76~88 Mhz
for the Majority of former AM/MW Radio Stations to Transition
to using IBOC.
http://groups.google.com/group/rec.radio.shortwave/msg/c2d18eac3b6437fe
.
IMHO the Best most practical use of two of the former
VHF Analog TV Channels is to Expand the FM Band !
"HD" Radio makes sense in an "Expanded" FM Radio
Band to cover 76 MHz to 88 MHz to create and additional
60 Digital Audio Radio Channels for many of the AM/MW
Radio Stations to Transition to . . .
Simply by using the TV Spectrum from the former Analog
VHF Channels 5 and 6.
The future of Terestrial Radio is in FM HD-Radio Broadcasting.
The FCC should have simply left the AM/MW Radio Band
remain Analog and simply fade away.

Plan For The "HD" AM/MW Radio Band :

Why Not ! - Leave AM Radio Alone {Analog Only}
http://groups.google.com/group/rec.radio.shortwave/msg/f64c4f482b701d06
The Best short-term uses of FM HD-Radio Channels are...
