[Elecraft] K3 - computer communications

[John R. Lonigro]

Phil:
The easiest way to check things out is by substitution.  First try a 
different computer, preferably one with a built-in serial port.  Do you 
have a spare one that wasn't affected by the event?  If not,do you have 
a friend with a laptop (and a USB-serial adapter) who wouldn't mind 
having Logic 8 installed temporarily as a test?  Do you have another 
radio (not necessarily a K-3) that you can check with  your current 
computer?  It seems to me it might be possible to substitute all 3 
components (radio, computer, USB-serial adapter) one at a time and come 
up with the answer.  If Logic 8 worked with no problems before, I doubt 
the software is the issue, but you could also try different logging 
software as well. 
Hope this helps.
