I would have thought somebody must have heard this, so why no comments?
I am interested to know what happens when a
long as the 25HZ tone was received by the
detector circuit on the AM Stereo radio then the radi could receive the Stereo
AM signal.
I listen to Radio 2CA in Canberra without any problems, Canberra is around 300
miles away from here.

from receivers using a wider bandwidth, and of course this recording is getting
some adjacent channel interference

Hi!
Okay, it seems that Australia used the Motoroller method for transmitting
Stereo AM in the end after a battle in court over here, the U.S. apparently
used the Magnavox method or the Haris method, nothing was tightly controlled by
the FCC until it was far too late smile.

I think it's important if you want to broadcast long distance, especially in
countries like the USA, Canada or Australia where there are people who don't
live in the range of many FM stations.

Okay fine and I appreciate you looking this up in Wikipedia however not
everything on Wikipedia is accurate, I know someone else who
is well informed on this topic and - whilst I'm not disputing the standard

mention of the Harris system back in the 80s.

Hi Dane,
From Wikipedia:
C-QUAM is the method of AM stereo broadcasting used in Canada, the United
States and most other countries. It was invented in 1977
by Norman Parker, Francis Hilbert and Yoshio Sakaie, and published
, quite nice audio so - for those who have never
heard stereo AM before - take a moment to enjoy.

Back in the 80s when I was visiting my parents in California, there was a
stero AM station. But I didn't have any stereo AM receivers. But I did have
two portable radios. I discovered that if you tuned them just right, you
could get the stereo sound.

Yep, that's how I used to do it back in the 80s, was a Teenager then and had no
buying power smile., its a crewed way of doing it but it did work to an
extent.
Of course, that procedure you outlined very much depended on the method of
broadcasting Stereo AM.

Hi Dane,
Thanks for that information. I didn't know that there was stereo am.
Could you please post the direct link because all I found via google was a
guy introducing a stereo am tuner, announcing that he would play it and then
stopping after a quite boring show of unwrapping the thing:

I think I know the Sony Walkman Stereo AM Walkman you're referring to, its
easily identifiable by the very large band switch on the face of the radio, I
used to call that Walkman the Biscuit Radio as the band switch reminded me of

Maybe the Melbourne station used SeQuam like the system that was adopted in
the states. Stereo separation was pretty decent and most of the big gun
radio stations in Pittsburgh broadcast in stereo 24 7. by the late 90's
stereo AM went buy the wayside like HD AM is pretty much done around here
Yes, Australia used the C-QUAM standard for AM stereo.

uses quadrature amplitude
