Heard my 1st AM/MW "HD" Radio Broadcast - Today 6 OCT 2007


Time : 1253 PM PDT in Twain Harte, CA


Radio Station : KFIV 1360 kHz @ 4000 Watts from Modesto, CA
KFIV =http://www.k5radio.com/main.htmlhttp...bin/amq?list=0...
- - - So the Digital Signal at 1% would be 40 Watts
Transmitter and Towers are located between Modesto
and Riverbank, CA. {ERP is 'only' 950 Watts Nights}http://www.radio-locator.com/cgi-bin...=KFIV&sr=Y&s=C


Heard the end of Glen Beck followed by Fox News at
1 PM PDT; and then the Jerry Doyle Show.http://www.kfiv1360.com/pages/KFIVweekends.html


Audio Sound Notes :


Voice sounded Thin and Tinnie with an Echo


Bumper Music in Stereo was OK.

Actually the distance was about 55~60 Miles and it was
the 1st AM/MW "HD" Radio that I have been able to Hear
up here in Twain Harte, CA.


Again the Stereo {Bumper} Music sounded OK -but- the
Talk Radio Hosts and the Fox News Readers voices all
sounded thin and tinny with an echo. I assume that this
was due to the KFIV 1360 kHz Radio Station's Audio
Processing or may be the Fringe Area reception
characteristics of IBOC -idk-


In general the few FM "HD" Radio Station's Music Sound
and Voice Quality that I have heard has been 'as good'
or 'better' than the Analog FM Radio in Stereo up here in
the Foothills; that I can get from the California Central
Valley Cities around 60~90 Miles away.


Currently using a Vertical Rectangle Loop Antenna that is
about 6-Feet High by 24-Feet Long (60-Feet Around) with
a Coax Cable feed-in-line. Pointed at Modesto, CA.
Plus a Radi-Osophy HD-100 Radio.

Hello and Welcome to the "HD Radio" NewsGroup

- Stereo ?

David, { Yes I Did Say "Stereo" }

Yes it is my understanding that the iBiquity IBOC's Hybrid
AM/MW "HD" Radio's Digital Side Bands do provide Stereo
Sound to AM/MW "HD" Radio Listeners.
http://en.wikipedia.org/wiki/HD_Radio

About iBiquity HD Radio = http://meduci.com/ .
Each AM Radio Station is allowed to transmit one
Stereo Digital Channel, and cannot stream multiple
channels, as in the case of FM HD Radio.

About IBOC = http://en.wikipedia.org/wiki/In-band_on-channel .
It is based on the Principle of AM Stereo where it puts
a Digital Signal where the C-QUAM System would put
the Analog Stereo Decoding Information.

Foti on AM HD Radio: 'No Static at All' {and Stereo}
Radio World OnLine -by- Frank Foti
http://www.rwonline.com/reference-ro...d_foti_1.shtml
* With the rollout of AM HD Radio, the senior band not only
offers no static at all, but Wide Frequency Response that
is equal to FM, and - ready for this? - Stereo!
* It's still a bit surreal to realize that the Audio Signal
emanating from an AM "HD" Radio contains 15 kHz
Audio response, Stereophonic Sound, low noise floor
.... and ... no static at all!

HD Radio Ready for Prime Time
Radio World OnLine -by- Glen Clark .
http://www.radioworld.com/reference-...d_glen_2.shtml
* AM HD is stereo (in "enhanced" mode).
* I found that the AM "HD" Radio System usually stayed in
Stereo Mode when the daytime signal strength was more
than 5 mV/m,

AM/MW "HD" Radio is 'by-design' Engineered to provide
a Pair of {Left and Right} Primary Digital Side-Bands and
that these Two Side-Band can be used to produce "Stereo"
sound from a "HD" Radio that has a Two-Channel Audio
Amplifier and a Pair of Speakers.
