I usually have trouble distinguishing co-frequency stations in the

spot in the stereo image from the other, making them quite easy to
discriminate. It's really rejuventated my interest. I'll have to get
out the old dusty loop and see what happens.

The older Sony sets were neat because you could switch between decoding
systems ... which sometimes helped in using them as AM DX sets rather than
just stereo receivers. Problem is, as you've discovered, there is less and
less stereo broadcasting to listen to. I wonder what's happening in Japan,
where AM stereo was booming and there were multiple receivers on the
market (including super digital portables from Sony and AIWA). Those sets
are off the market and they don't seem to have replaced them.
