[Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[Chris Johnson]

Hi Eric,

I do not have the AUX cable.  As described in the video, I am only using the RCA cable from the Flex 3000 into the KAT500 and then another cable from the KAT500 down to the KPA500.

I am not using this with a K3 radio, which in that case,  would only use the AUX cable and no RCA Key Line.

This can be done either via the the AMP keying line RCA connectors on the Rig, KAT500 and the AMP, or via the KPAK3AUX cable connections between the K3 and KAT500 and between the KAT500 and the KPA500 when the K3 is used.

One correctly through the KAT500 to the amp (usually via the KPAK3AUX cable), and the other incorrectly via a second path directly from the Rig's Key out RCA connector directly to the amp.  This second path will nullify the KAT500's attempt to open the AMP keying line to theMAP during tune.
