[R-390] 60 Hz on Audio

[ANTHONY CASORSO]

If you have already mentioned it, my apologies. Are you in MGC or AGC mode? If AGC, what happens in MGC mode? I am thinking that the broader filter lets more noise through which generates more AGC, reducing the IF gain. If in MGC mode, then this is obviously not the case.
