[Elecraft] "K3 VFO A Not Responding" message

For it to lock your computer totally it is usually a problem in the driver
area and I would suspect a problem with the USB to RS232 interface if that
is what you are using. I know proper RS232 ports are rare these days but you
may consider a PCI express type RS232 port. After some frustration with
similar problems over the years I have made them go away by not using the
USB to RS232 solutions, some of them just seem a little sensitive to RF
despite common mode chokes.

Not much help but just a thought.

Regards.

Hi Guys,
 
Hoping someone can help me fix the following problem which is driving  me
crazy:
 
For the past couple of years, on the top of the N1MM Logger screen, I often
get the message "K3 VFO A not responding.  When I get this message  my
computer is locked up and I'm unable to log or transmit.  A very  bad
problem to have when running stations during a contest.  The  problem seems
to occur aprx. every 15 minutes when operating RTTY and aprx.  every 30
minutes on CW.
