[Elecraft] Test serial-to-USB converter

[Nr4c]

Call support for assistance. They will walk you through the tests. Have lid off and DVM handy. Very simple. 

I had a choke on the ground line go and it was very obvious with visual exam.

I also lost communication to my MDS rotor, which uses a built-in USB cable, which I believe may also be a serial-to-USB arrangement.  I checked things out a bit, and I can tell that my USB ports all seem to work.  I also tried the K3 with another computer and was unable to communicate with it.  However, I also tried a direct serial-to-serial cable from the K3 to the first computer, which has a serial port, and was also unable to communicate.  I am now unsure of the location of the problem.  I am willing to go with whatever works.
