Hi Alberto  I found argo to be very sensitive and easy to use.  When watching

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,
