[Elecraft] K3 Attenuator Turning Itself On

[Don Wilhelm]

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.
