[Elecraft] FW: QSK THUMPS?

[The Smiths]

I've heard this as well.  Mostly when doing QSK with the Sub Receiver on, and even more so when in Diversity Mode.  I think that it has to do with your Xmitted signal being heard by the receiver.  Wayne had adjusted this at one time, but it seems to be an issue again.  
I find that if I turn on the NB it helps reduce it.
