Wait, it was not KL INT, but KY INT for 'key interrupter'. I think I have it
figured out.
I recently sold my SteppIR vertical which required me to use the PTT Key
line to prevent the amp from keying while the SteppIR was moving. This piece
was used to interrupt the PTT in the AUX cables (missing

Mike,
I recently had a similar problem with my KPA500. A couple of components in
the low frequency T/R filter blew out. The amp made a trip back to the

No, the asterisk on the KPA is missing. Nothing appears on the left of the

and another one from the KAT500 to the KPA.
I did recently change my
Some of those connectors can be a bit finicky, wanting to be snugged up

Ask me how I know... wiggle, snug, wiggle snug.

It is definitely a cable problem. If the asterisk is not being displayed on
key-down, then the
amplifier is not going to go into transmit. recheck the cables all the way from
the K3 to the KPA
to see what came undone. Find and fix that and the KPA will come back to life.
You might want
When you key the K3, does an asterisk show up on the left side of the KPA’s
LCD? If not, check the AUX or PTT connections to the KPA500.
Otherwise, let me know so I can follow up with you to get you going.
