This is a problem with the Centurion as it uses mechanincal relays and it will bounce. If you use an original Orion or the Orion 2 you will hear popping in your receive speaker after going from TX to RX. If fact, you will hear a pop pop as the relay bounces. This is especially noticable on 75 meters SSB.

The Orion has a TX to RX hang timeout of 13 to 15ms, which is just too fast a transit time for the Centurion to fully clear the relays back to receive.

Maybe the K3 transit time is just too fast for the Expert? IS there a menu setting which could change the RX hang timeout on the K3?

I used Centurion with K3 for a few years. Connected directly to BK, not Key
in/out. No problem that I could sense.

Now I use Expert 2k-fa. Now I have a real problem as the relays are
bouncing.
