[Elecraft] "K3 VFO A not responding" message

[Rick Bates]

So what you're saying is that the N1MM software is the common thread with
the multiple QTH and computer combos?

I presume that it is up to date, along with any OS updates, drivers etc.?
What bit rate are you using on the serial line?  Maybe try other settings?

I've been using HRD with good success and V6 will handle the K3 even better
since they loaned on to the author.  Juzz sayin'

Hi Guys,
 
I've been a happy K3 owner for aprx. 3 years.  Regardless  which CPU I use, 
I've always had an occassional problem receiving the error  message "VFO A 
not responding".  When this happens  while "running" during a contest it 
presents a serious problem as the  computer and radio lock up for aprx. 30 
seconds.
 
During this 3 year span, I've operated with a dozen  different Windows XP 
and Windows 7 computers, always using N1MM Logging  Software.  I've operated

from several different QTH's and have the  same problem.  I always connect 
via a Serial Port  regardless of which CPU I use and have not tried a USB
to 
Serial Adapter.  During the past few months, this problem has  really 
increased, such as: during last weekends CQWW  Test, I got the dreaded "VFO
A not 
responding" message and computer lock-up  at least once every hour.  By the 
way, I do not have a 2nd  receiver in the K3 so I cannot say if I'd have 
the same problem with VFO  B.  
 
I'd be grateful for ideas on how to eliminate the "VFO A not  responding" 
problem.
 
Thanks & 73,
