The way it goes to all-digital is to move the sidebands back in to the center. When that happens, there will be no adjacent channel hash, or at least not much. Everything will be on-channel. The power of the digital signal will also be increased significantly, though not to the power used for analog. KGO-810 will not be killing 800 and 820, and will no longer be 50kw. The power for the digital signal will be calculated to give equivalent coverage. I have not figured what that will be. I personally do not think that AM radio will survive the estimated ten year plus transitional period. At least not in a way that is fair to all concerned. That seems to be just what the iBiquity consortium is banking on, that it will weed out the lesser-financed and more marginal stations leaving the big, well-financed companies that have the resources to weather this. Financial jamming.. FWIW, I have asked one of the local IBOC station engineers if there is a way to do a test in the all-digital mode. This would give the few of us with HD Radios the chance to see if IBOC DX can exist. So endeth my once-monthly IBOC pest, er, post...
