[Elecraft] Need help with K3 vs Win 10

[Don Putnick]

I'm having problems controlling my K3 with applications under Win 10. Truth
in lending: Win 10 is on the Bootcamp partition of my MacBook Pro running
Big Sur.

The K3 Utility on the Mac side works just fine, so I know the cable is
okay. I can send CW via the Utility's terminal window. I can't on the Win
10 side, but the connection is established. N1MM is a mixed bag. I can read
and control the VCOs but I can't get the macros to send CW.

I'd appreciate any suggestions anyone has to offer. Not urgent but
frustrating. I have until Field Day.
