It depends where you are and when you tune in, as lately they've been in flux.Info on 103.3 and 104.1 correct.
Stations like BUR and UMB just have an HD1 signal
101.7 HD2 is now Evolution, 100.7 HD2 now RKO, 107.9 HD2 now WBZ newsradio
I don't have an HD radio with AM.The HD radio site lists 1430 as Mia, music in Spanish, which ended in July of 15.But as said above, WBZ now the only AM station using HD. You get splatter on an ordinary radio though awhile back it must have been turned off as I could get KDKA with minimal splatter, not unable to be heard.
