[Elecraft] Configuration of K3 and RigExpert Standard

[Doug Faunt N6TQS +1-510-655-8604]

I've finally gotten it together to hook this up.  The RE Standard has
a CAT port, which is configurable to RS232, but without DTR and RTS,
so I used the extra serial port (which does have those lines) for the
connection to the K3, and used the CAT port with a cable to the
rotator control, which only needs TXD and RXD.  Since these ports look
like standard COM ports to the computer, no problem.

I have now downloaded the firmware to the K3 using the RE serial port,
and MixW seems to work fine, although I have misplaced my stash of
15-pin HD connectors, so haven't gotten FSK hooked up yet.

And on that issue, there was some talk of being able to reconfigure
the firmare so that DTR could be the FSK input when in DATA mode.  I've not
been keeping up thoroughly- has this happened?  I can't find a mention
of this feature.  It would allow real FSK without any extra hardware.
