We just put a new cable order item onto the order page yesterday. You may want to consider the E850468 "Optional KAT500 to KPA500 Cable". It will also work as a K3 to KAT500 cable. It doesn't include the Y or Tx line keying adapter that are included in the KPAK3AUX cable set.

You can't use one 15-pin acc cable from K3 to KAT500 and then an RCA cable from KAT500 to the amplifier. The RCA key line path uses a separate relay pole from the key line in the 15-pin cable. For the K3 to KAT500 to KPA500, you'll probably want two of the 15-pin cables so that the K3 is aware of the KPA500. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Johnny Siu Sent: Tuesday, October 09, 2012 1:14 AM To: Elecraft Subject: [Elecraft] connection among K3, KPA500 and KAT500 Hello Elecrafters, I notice there have been discussions about the above in this forum. If I only have ONE KPAK3AUX cable, should I connect it between KAT500 and K3? The connection between KPA500 and KAT500 is just a RCA cable for PTT. Any ideas?
