The 775DSP has control system timing problems that generate thumps
and bumps when on CW split, as well as severe leading-edge power
overshoot in the PA.
None of that is good on the PA transistors, or other people trying to
receive weak signals nearby. I would suspect the power overshoot as
causing the problem before the RX antenna.73, Tom W8JI
