I wish I could avoid the distortion that I get when doing Kahn ISB Stereo. Or well, the distortion that regular receivers end up with. Seems there is just some destructive cancellation going on there. There must be some other magic I'm missing. It sounds pretty good when rammed through a proper ISB stereo decoder though.

Fair signal via the Poland, New York, SDR ...
2216 UTC: OM-voiced ID, then "Geburt Einer Nation" by Laibach.
2221 UTC: "Victory (Single Mix)" by Killing Joke.
2225 UTC: "Alone" by Weedeater.
2228 UTC: "Kerosene" by Big Black, which started after an extended pause.

2253 UTC: Checked back and heard decent-sounding audio on "Down in the Park" by Gary Numan (a fave of mine) via the Fair Hill, Maryland, SDR.

The music can be heard normally, but there is a bit of oversaturation. Maybe you should lower the audio signal level a bit?
On 6962 AM is now, 22.26 UTC guitar music.
22.36 UTC off signal.

2227 UTC - Signal is S9+ in WNY, audio is a bit distorted.
2230 UTC - Signal is fading now, deep fades.

Where I'm getting into trouble is with the L - R stuff on the upper sideband. The lower sideband is the L + R channel. The other sideband is suppose to be L - R. That's where things get messy, it seems.

Switched to doing CQUAM AM Stereo. Regular receivers seem to not have the same sort of issues. Interesting experiments.
-
I understand. Ideally, nothing happens in life, I think it will do for a homemade transmitter. Although you can also try to adjust the high and low frequencies so that there is no audio choking.
On 6963 AM is now, rock music.

I think it's sort of a flaw of the Kahn AM stereo system. Or...at least in my implementation and/or understanding of it. The trick is to get both LSB and USB not to destructively interfere when shoved through an envelope detector. The CQUAM system doesn't have these problems, it seems. It also doesn't have as good stereo separation, IMHO. CQUAM was a lot easier implement, too!
