[Elecraft] RIGblaster Advantage for Serious Digital Modes, with KX3?

[Nicklas Johnson]

I find that putting my KX3 into "DATA" mode to bypass all the EQ, setting
the volume to "30", and setting both the in and out gain of my sound card
to "8" works perfectly well.

Yes, the volume on the KX3 isn't "fixed", so I "fix" it manually by knowing
what number I want to set it on (30) which gives it about the same gain
that my little headset adapter soundcard ($10 on Amazon) gets from my
Icom's fixed output.

Enabling DATA disables EQ and compression. It works great.

No complaints, and I make perfectly reasonable data mode contacts
consistently with it.  I did find that I needed to build a ground-loop
isolator for the KX3 to play nice with the computer, evidently because
either the Rigblaster I use with the Icom, or the Icom itself already has a
1:1 isolation transformer, whereas the KX3 apparently does not.

worth supporting.
