i tried a few combinations of audio high pass/low pass and different
ssb in each ear. there are some interesting effects you can get that

can get the feeling that the signals come in one ear and out the other
as you tune across them... interesting once you get used to it on cw,
but probably not much use on other modes.


RTTY might have a ping-pong game on acid effect.
