Hi Mike,

Thanks for your reply and the screenshot.  I read a posting of yours several 
months ago where you
mentioned about some clipper diodes across your isolation transformer.  I 
lashed up a limiter here
consisting of a 10 ohm series resistor then a back-to-back pair of  diodes.  
It's in the lead between
my rig's external speaker jack and the input jack of my DSP-59+ filter.  It's 
really made a difference,
with the overload light not coming on nearly as much, and I can run the 
receiver's audio gain a lot
higher to give Argo and other programs more signal to work with.  That was a 
good tip!
