Right. I don't have a receiver for AM broadcast where
I can do that anymore. I've always been fascinated by
that rolling resonance effect you hear from 80 through
40 meters, especially with short wave stations, even
1's running ssb, that swirling sound as if someone was
talking through a tube that keeps shrinking. I always
wondered why those particular bands are more likely to
get that rolling effect. You'd never hear it on 10
meters for example, or near the bottom of AM
broadcast.
