[Elecraft] [K3] Serial cable for my new K3

[Don Wilhelm]

Roger,

Use the straight through cable.  For your future reference, that is the 
information that can be found in the K3 manual on page 18 in the 
description of the KIO3 module.

Only 3 wires are required in the cable TXD, RXD and Signal Ground (pins 
2, 3, and 5) for communication with the K3.  DTR and RTS are also 
available for PTT and KEYING from the computer serial port, so if you 
plan to use those in the future, buying the serial M/F cable would be a 
good choice.

73,
Don W3FPR
