Well the point in the first place was concerning the "hidden transmitter".
My point is, and I think you have made it, is that despite everything that we may do in software and operating procedures, if you are using HF, QRM is going to happen...QRM happens. HF, love it or leave it and go play on a 2M repeater.

OK - but only if C and D were in QSO first. But as I say, if A and B dont hear anyone else, the only thing that can happen is for C and D to live with it, or QSY. It all neither here nor there, it comes down to the golden rule "Do unto others as you would have them do unto you" And if automatic stations want to play that game, there are plenty of people out there with big signals that will.
