[Elecraft] connection among K3, KPA500 and KAT500

[Richard Ferch]

Johnny,

I don't believe that will work. According to Dick K6KR: "For amplifier 
key line interrupt, you should use two 15-pin cables, or two RCA cables 
(radio to ATU, ATU to amplifier). But you can't use one of each. The RCA 
connectors and 15-pin ACC cables use different poles of a double pole 
amplifier key line interrupt relay." (see 
<http://www.mail-archive.com/elecraft@mailman.qth.net/msg144163.html> 
for Dick's full message, which has other useful information about this 
topic).
