Thanks for the link, David.
I have my own take on this, which is more generic and differs a bit from
Eric's. Part of it is because I run SO2R feeding my mic through a YCCC
box, but mostly it's the result of my greater understanding of audio and
the fundamental causes of hum and buzz. And I prefer solutions that are
effective, free, and simple. :)

All of this advice applies to both SSB and digital modes, except that I
no longer recommend using most internal sound cards for digital modes
because inexpensive USB sound cards work a lot better.

Jim,
Good stuff, thanks!
I also recommend K3NA's article on adjusting SSB audio chain. While
specific to Orion, the principles are adaptable any any rig.
