I believe the Key line interrupter interrupts pin 10 rather than pin 11 after reviewing the K3 and KPA manual. I don't use the Pin 11 option on the KPA (it's disabled) rather use the keyline interrupter and RCA jack cabling to interface all the keying interruption which includes my antenna switch.
Thanks for your concern and don't hesitate to correct me if I've made an incorrect assessment. 73 jim ab3cv On Mon, Apr 15, 2013 at 9:06 PM, Terry Posey <tpo...@nettally.com> wrote: > Hi Jim - > > You are well on your way to 6m success with the K3/KPA500/KAT500/PR6 line > up.
