[Elecraft] Serial Cable routing

[Jack Brindle]

Oh Fred...

You are mixing Apples and Lenovos… We are talking two different connections. The ones I listed are for the serial port. The connection you are talking about is the 15-pin AUX cable, which indeed goes from the K3 to the KAT500, then a second from the KAT500 to the KPA500. These are two totally different communications media. Also note that RS-232 is _NOT_ involved in the AUX connection, nor is the computer (or your Pig box).

The KAT500 indeed does interrupt the KEY line that is included in the AUX cable running from the K3 to the KPA500. If you have separate phono-cables that connect the K3/KAT500/KPA500, you should immediately remove them! That signaling is handled in the AUX cable! I suspect you have things cabled properly, though. Otherwise you wouldn’t be cleaning my clock in all those contests!

Perhaps we should have walked further to the IN-N-Out… :-)

The instructions told me to go to the P3 before the K3, and to put the KAT500 in between the K3 and KPA500.  This has worked for me from the very beginning, not long after the Big Bang, and for ever after ... well, at least as far as we've gotten.
