Ian:
I don’t think you are understanding what I am saying...
You DO NOT use "Windows Audio" OR the laptop's soundcard at all. The
"Soundcard" is built in to the MicroKeyer 2. It is specially designed for
this application, with low noise and high dynamic range plus a standard
codec driver. So you just connect the rig to the MicroKeyer 2 and the MK2
to the laptop using USB and everything works, even my HC4 Boomset through
the MK's External Mic in.
And there is no need for special CAT commands in the macros or the use of
PTT by radio command that can get messy since Logger just sends the CAT
command like a UDP packet.
But, to each their own, if it works for you, I'm glad.
I look forward to working you on SS. I will be using my K3 driven with my
MK2 from home.

I will probably use the KDVR3 with N1MM for Sweepstakes this year, as I'll
be a guest operator at another station (with real antennas), and will be
taking my own laptop. The built-in audio on the laptop is garbage (when the
gain is cranked up high enough for a Heil HC4 as input, it has all sorts of
nasty noises in it), and none of the USB audio devices that I have seem to
do duplex audio in the way I need for N1MM software voice keying....
I do use N1MM software voice keying for other contests, including SO2R SSB.
It works well most of the time, with a decent sound card. For a simple
single-operator contester who just wants to have a convenient recorded CQ
and maybe exchange, the KDVR3 method can be easier than messing around with
Windows audio, and there's less to go wrong...
