[Elecraft] KAT500 + AUX Cable

[Richard Ferch]

I was not actually asking about which lines needed to be connected 
within the cable, although that is another important aspect. I was 
simply asking whether it is necessary to purchase two complete KPAK3AUX 
cable sets. It seems to me that with two complete KPAK3AUX cable sets, I 
would end up with at least one surplus Y-cable (assuming I need the 
first one) and a surplus key line interrupter (or is it actually two; 
i.e., does the KAT500 even need a separate interrupter?).

Stated otherwise, I'd like to know whether the only way to purchase (as 
distinct from fabricate) the necessary additional 7-wire DE-15 to DE-15 
cable is to order another complete KPAK3AUX cable set, or whether it is 
possible to order the DE-15 to DE-15 cable on its own (on the assumption 
that that is all I would need, of course).
