Wow, thanks Carl! Tha Dood liked it too, and thought Motorola should have done more to promote like that. I agree, and they could have sent lots of cassettes, showing how AM stereo sounds to audio stores and give them away free.
Having a cold this past week actually helped, because I rested sitting in front of the screen more.
Listening to the demo files again, I might want to re-do them, since I just flipped through files in a playlist, but I could plan it a little better and cover more types of audio, including how AM stereo might sound with audio the way it's produced today.
Sure AM Stereo is practically dead and listeners don't even notice stereo anymore but I still think its cool folks are still willing to experiment with stereo.
I have a cuthbert stereo transmitter, after some tweaking its not a bad little rig. I've long thought about stuffing it in an outdoor box with a CB whip strapped to it.
Legacy, the antenna material will make little difference. I suspect you are losing RF between the TX and antenna, moving the TX closer to the antenna with minimal line loss will be your ticket to decent coverage.
I got a Directed brand bookshelf DHHD Radio system that is supposed to decode AM stereo, and I even saw a demo of it doing so, on video, but I haven't been able to successfully decode an AM stereo station either.
