O n AM IBOC is used and does intact improve the sound quality significantly. The downside is that each adjacent channel is smothered in noise garbage caused by the digital signal. On FM the stander channel is 200khz wide but in the case of Hd radio 50khz at the top is use for the HD2 and potentially HD3 channels. I have yet to hear anything on FM that truly sounds better than the standard fm broadcast signal. Also for AM while it is true the sound is improved it simply means that the standard right wing rant talk radio sounds clearer now and I have no more interest in listening to it than I had before.
