key line interrupter

Howard Sherer
I have a 15 pin adapter with pin 10 removed as a ptt interrupter. With it
inserted in line with my acc cable on the rear of the K3 to the KPA, the
amp still keys. I would like the KPA to not key when I am using other amps
for VHF. I can only do this by removing the acc cable from the rear of the
K3
I do have an additional PTT cable between the K3 & KPA with a switch to
disconnect the ptt line but the KPA still keys?
