[Elecraft] K3s won't connect to PC

[Christian Friess]

Hi Jim,
even if you haven't changed any settings before I would check the COM 
Port settings
like Baud rate etc. at the N1MM+

Check the settings at the K3S too.

Next should be the connection from K3S to PC. If you have another cable. 
Give it a try

If you boot the PC make sure the K3S is already ON
