[Dx4win] MicroKeyer2, DX4WIN, HDSDR and Omni-Rig

[Radivoj Kar, F6GNZ]

I have
updated my shack with an SDR which I want to use for reception only  and keep my existing MK2, FT1000MP+ IC706 (for
50 MHz) for transmit only.
I can control
SDR with HDSDR program and synchronise FT1000MP/IC706 frequencies/modes via the
Omni-Rig program interfaced with HDSDR. This combination works perfectly, but
now my DX4WIN becomes useless as it can’t read nor control the radio, saying “ie_Open,
device already open” and
“Could not
open COM4 for keying, ie_Open, device already open” when I try to Start the Radio.
So, I can’t
log the QSOs with related radio data (mode, freq’s) nor use spot clicks to set
up the TX/RX frequencies,  nor  control my antenna rotator.
Is there
any way to make the above combination work together???
