Tom,
I don't know the particular logistics of making this happen but
wouldn't the amplifier (keyup) be at a minimum current state? So, is
it necessary to switch the amp on and off between characters? I
guess QSK wouldn't be possible under those conditions, but it should
shut up the offensive realy noise. And this from a guy who has never
owned an amp. However, with the hole you were making in the band
yesterday, I am sure tempted!!
