Elecraft K3 dead spots in the FULL QSK RECEIVE AUDIO when operating QRQ CW mode

[Chuck aa0hw]

NOTICE the DEAD ZONE in the following SCOPE view of sending a couple of 55 ms DITs... while trying to listen for how much QSK RECEIVE AUDIO is between those dits....NOTE:  you will see a GAP of "NO AUDIO" from phase cancellation due to the technique that the K3 firmware uses to try and get "more" QSK audio for the QRQ OP's 

the steady tone in the background is from 10.000 standard time's signal...and the RED arrow is pointing at the DEAD ZONE of NO QSK AUDIO IS HEARD...the dead gap also causes key click/snapping sounds when a tone is present
