[CQ-Contest] WPX CW Signal Quality Concerns

[N4ZR]

Pardon a dumb question, but isn't the TXDelay normally from TR relay 
actuation to first RF? I know that's the case with my K3.  In that case, 
unless you're running QSK, I don't see how that would cause clicks 
throughout the transmission, just at the beginning of the first character.
