Garry,
I don't know about Ira's setup guide. However the one I did
based on Router 5 and has been available for a long time via
"help | download documents" in Router and from the microHAM
list on Yahoo was fully checked on my own microKEYER and K3.
I have recently refreshed most of the example configurations
to reflect Router 7.6.x.

DATA A is far more convenient. I would not even consider
using USB/LSB unless the transceiver completely lacked a
DATA mode (e.g., the Kenwood boxes).

PTT is not germane to any problems with PSK31 in MK.
First, if DX4Win is configured properly to use "PTT Control"
in PSK and CW it should use the CAT port DTR line. I do that
in all my configurations to minimize the number of virtual
ports needed and reduce the operating resources needed. It
also helps with the "keep everything in the first 8 COM
ports problem."
Second when using "Line In" on the K3, microKEYER should be
configured for audio switching "BBB" which does not change
based on PTT. In that case PTT is used only for PTT and
not audio switching.

Your issues are probably confined to the K3 set-up ... make
sure you select "Line In" using the "mic sel" menu while
you are in DATA A mode. There is no substitute for understanding
the OEM manual.

Note: the original copy of this response sent from microHAM
support includes a copy of the example configuration.
Unlike the meddling from W3FPR, the only issue is
probably in your configuration of the K3 Line In.
There is no reason to give up the other features of
microKEYER (including WinKey and automatic mic switching
and mic override of the soundcard in voice contesting)
simply because Don continues to trash microHAM products
used with Elecraft rigs.
