[Elecraft] KPA500 w/ KX3 & K3 & w/ KAT500

[James Bennett]

Hoop -

Something must not be cabled properly. I have the same setup - K3, KX3 on a coax switch going to the KPA500 and KAT500. I can operate either K3 or KX3 with or without the amp/tuner. If my K3 is powered off and I want to use the KPA500 with the KX3, there is no issue - I can press the OPER/STBY switch on the amp and it does what it is supposed to do.

I do not recall having to do any menu settings on either rig for this to work. Be sure you have stuff cabled EXACTLY as Fred’s book shows…

I have configured cabling as shown in section "9.8 The KX3 and the KPA500”, figure 9.17, which shows use of the Keyline Interrupter, RCA cables, E980232 Adapter for the KX3, et al, with an RF switch between the K3 and KX3 in order to input either to the KAT500/KPA500 pair.
