Sounds like you may have a strong AM broadcast signal that is
overwhelming the K3 input.
MW signals will be attenuated by the Low Pass Filter, but those signals
below 160m will not be.
The K3 does have some suppression of AM Broadcast band frequencies, but
it may not be sufficient in your case.

Yes, I can turn the attenuator off once I'm on 160M, but within 2
seconds of turning it off
it will turn itself back on.
