[Elecraft] K3, 15 Pin Acc Cables - Commercially Made

[N2TK]

Guess I got lucky. Had an old VGA cable. Cut off the one end. Terminated it
in a female DB9 RS solder plug with a plastic hood and added a transistor
switch for FSK. There were no coax cables imbedded in the VGA cable. Several
single wires and a few twisted pair.

What I would like to do when I get time is terminate the VGA cable in a box
with terminal strips. Add jacks to the box to break out the signals on the
ACC jack. This way it would be easy to add cables to other external devices.

Maybe Elecraft or someone will come up with a plug in box to do this?

N2TK, Tony

Another reason NOT to use the computer-use socket on a ham radio.....  Tiny
wires, tiny pins, weak strain relief.... do I need

say any more.....   Come on, designers:  remember your customers have normal
sized hands and weak eyesight!!!

It is not fun.  But in that application, it was the only way to get the
correct connections, the correct wire type, and so on, connected to the
device.
