eddie,
its very easy to hear and see when theres multipath on fm, local signals flutter at a time varying rate, they hit a peak then flutter back to where they usually are with a woosh wooosh woooosh sound as the multiple paths arriving at different phase angles sum and cancel each other,

on ssb the effect is similar to the effect you get when switching the polarity of one loudspeaker on a hifi cancelling the bass frequencies but its not switched, it is a variable in and out of phase sound.
