[Elecraft] K3 - MixW interfacing

[Ray Albers]

So after having built a KX1 15 yrs ago, and 5 yrs ago acquiring a KX-3,
I've finally gotten a [used] K3.

I use MixW for logging (I no longer use it for digital modes, and haven't
upgraded it for years). I had interfaced my old ICOM 746PRO  and it worked
perfectly, entering the frequency into the log.  Now I can't get the K3 to
do it.

I'm using a Dell laptop running Windows XP. I've tried interfacing radio
and computer with a serial cable (yes, the old laptop actually has a serial
interface) and also with a serial to USB converter, with no joy.

A bit of Googling told me that folks have gotten the interface to work by
selecting Kenwood as the radio (in MixW) and then selecting Elecraft K2 as
the model. Still no luck. The latest is that in the Freq column, MixW
displays
-13677 and that doesn't change when I turn the big knob on the K3.

Any suggestions?
