Hi John,
       a suggestion : Argo starts with the AGC on by default (probably I will change this).
In many cases, especially if you have strong statics, switch it off. When it is on, the statics are
almost totally invisible on the screen, as the gain reacts in zero time (the signal is delayed),
but an undesirable side effect is that dots and dashes are chopped for the duration of the
static, due to the lowering of the gain of the magnitude->saturation mapping.

So perhaps it is better to accept vertical stripes on the screen, but having unchopped
dots/dashes.

Good luck with your efforts,
