Nick,

The microKEYER and DXD Doubler presently work fine for SO2R operation.
I have a pdf showing the hook-up information.  Those who might need
it can e-mail me directly.

microHAM will be introducing "two radio microKEYER"s at Dayton ... the
details and specifications with the initial firmware release will be on
the web site (www.microHAM-USA.com) as soon as the firmware is finalized.

To what extent Writelog will work with the two radio (SO2R) microKEYER
is an open question.  However, the hardware and/or software interface
will be made available to any author who chooses to cooperate.  The
initial Windows interface will use the FTDI d2xx driver with Eltima
virtual serial ports and a CT/NA compatible LPT control interface to
facilitate early implementation.  An early update will include a command
(advanced) mode interface.   The interface for LINUX/Apple OS 10 will use
the FTDI USBSerial driver and respond to software command.

The two radio microKEYERs will also provide a "dumb" (no serial/no USB)
mode for use with DOS contesting software and a hybrid mode for use with
Windows command mode software that can use USB for radio command only.

73,
