[Elecraft] k3 - JT65

[Gene]

Problem solved.
Thanks to Bob, WB4SON and Bill, W0BBI, JT65 is now running well on my 
desk top computer with Win7.

To make a long story short my main problems were, (A) Line - In plug at 
the K3 had to be Mono, ( I had used Stereo on my lap top). (B) Cable 
from line-in had to go to speaker, green jack on the computer.   
Line-out cable at K3 to Mic, blue jack on computer. (C) Windows 7 shut 
down my Prolific USB to Serial converter but got it back ok.  Don't know 
why this happened but will keep an eye out for this. (D) Make sure the 
com port you set in the setup page of JT65 is same as the USB to serial 
converter you are using.

Thank you all.
