The system isn’t entirely 100 percent compatible with receivers as the PowerSide system favors one sideband over the other. Some receivers won’t see the envelope correctly and end up sounding very distorted when tuned to a PowerSide signal.
Again it all goes back to the receiver manufacturers and their for no good reason to make AM receivers so frigging cheap thus creating this incompatible nonsense through and through, be it for Kahn’s PowerSide format, or his AM stereo format, or even for standard mono hi-fidelity reception with the use of very very cheap IF ceramic filters. Even in the 80’s ceramic filters were cheap enough to make AM receivers as good as they should have been.
Problem Kahn had with his AM stereo system, as was the same with the Belar system was both used a combination of FM and AM modulation and were not 100 percent compatible with existing mono receivers. The only two (after the Magnavox FCC Foobar) were the Motorola C-QUAM and Harris V-CPM systems that were compatible with mono receivers.
