Hi jason
I can't disagree with you. I suppose I would have been more correct in
saying, QSK operation resulted in audible clicks in the headphones with P52
connected. Like you, I just moved the connector over to keep things tidy
whilst severing the offending connection. I haven't used my Omni VI+ for
years but maybe I'll give it an airing one of these days.
