[Elecraft] K3 : SSB modulation

[Tim Tucker]

Are any of you guys driving your K3 with W2IHY or other audio rack gear?  If
so, I'm curious as to the settings you ended up with on the rig.  I'm still
waiting for my K3 to get back from the factory, but I plan on running the
full stack of W2IHY gear with a Heil GM-5 Mic.  I imagine I will probably
end up with the comp and EQ on the rig turned off, but I'd like to hear what
others do.
