A & B hear each other but dont' hear C & D. But C hears either or both A and B.
If C is receiving D, then A or B is QRMing C.

HMMM By whom is C being QRMd. You didnt say who he is hearing as QRM. I am assuming that C is hearing either A or B or even both? In this case, if A and B were already in QSO, then C and D should QSY to start their QSO elsewhere. If the C and D QSO was already underway, and A and B started up, and they were not hearing either C or D (not probable as usually prop is two-way if it is strong enough for QRM) then C and D would either put up with it, or move since under this condition, they cant tell the other pair that the freq is in use. It is prudent for both parties, starting a QSO to insure that neither of them is intefering with an ongoing QSO, and by both checking to see (both automatic stations having the capability) if the freq was QRL - it would avoid inteference to others.
