Yes, the K3/KIO3B or K3S USB Audio CODEC behaves exactly like the K3
with analog Line In/Line Out.  The USB Audio CODEC is essentially
"grafted on" to the Line In/Line Out.  In fact "Speaker (USB AUDIO
CODEC)" is connected in parallel with the analog Line Out jack.

Please refer to the K3S Owners Manual and the K3S schematic package
on-line.

Not by a long shot ... you no longer have a hardware based FSK, a
K1EL WinKey keyer, support for multiple CAT connections (for syncing
an external SDR panadapter), the ability to mute the microphone when
playing an SSB voice file, access to dedicated CI-V and/or SteppIR
control channel, etc.  While you may not have used all those features
you certainly do not have the same functionality as you had with the
microKEYER II.

On a whim, I restored an old known-good workspace, changed the parameters to the new hardware configuration and after a couple of bumpy starts, everything worked fine. I saved a new workspace with these settings, and then I went back to the original profile, and it remained screwed up. Once again I shut everything down, loaded the new profile that I’d just created and it’s all good. The bad profile has now been deleted off the system and all is once again right.

One final question, does the USB audio connection from the K3s separate out the main and sub receiver audio in the same manner as using a physical audio breakout cable two and 3.5mm plugs? I would like to have a second instance of MMTTY set up to receive the sub RX audio, with the primary using only the main VFO. I used to be able to accomplish this using left- and right-channels in the MMTTY setup, but that doesn’t seem to work using USB. Not a major issue now that FT8 Dxpedition Mode seems to be all the rage, but I would still like to have this functionality if possible.
