[Elecraft] K3 comatose - sorted, thanks

[Greg - AB7R]

Stewart,

I also use a Microham device (MK2R+).  Click SETUP  for the radio port on the PORTS 
tab.  Set the radio to NONE and disable querries.  Save the configuration as 
something like "K3 Firmware".  Now it should work fine.  It may be a little slower 
than a straight native COM port, but it has worked fine for me for the past 4 
months or so.

Now whenever I need to update, I just click that preset and there's no problems.
