Jim and any others interested:

An article written in 1994 on the principle I was alluding
to. Way-back in 1999, AA2TX wrote Instatune which performed this for
the FT-847. KB5MU writes in 1999 that several other programs have
this feature (but the link is broken to the Amsat Store). Currently
Amsat offers: MacDoppler and SatPC32 (which I already have).
http://store.amsat.org/catalog/index.php?cPath=2
I'll have to check to see if it is implemented in SatPC32 (what
radios are supported). But most likely it does not support control
of either the K3 or KX3. Software mavens most likely can easily make
a driver that will work with SatPC32.

I believe the software is available on the AMSAT website and if you sign
up for AMSAT membership they will allow the download and send a CD of
the available software etc.
