As documented in the microHAM Users Manual for each interface, the
sound card in the microHAM Interface should *NEVER* be the Windows
default device or the Windows default communications device.  See
"Configuring microHAM CODEC" or "Configuring USB Audio CODEC" in
your users manual (as appropriate).

In addition, *always* use "Line (microHAM CODEC)" as the input (RX)
sound card in digital software.  "Headset microphone (microHAM CODEC)"
is connected to the microphone circuit in MK II (and not used in DK II)
for recording DVK messages only.  By setting the digital software input
to "Headset microphone (microHAM CODEC)" you are receiving via *audio*
*coupling* between your speaker and the microphone - no wonder you can
not copy anything in MMTTY!
