WABC's programming is simulcast on WPLJ's HD3 channel. Yet they never mention "WPLJ-HD3" in their legal ID at the top of the hour. Aren't they required by the FCC to state their HD channels in their legal ID, or is it not necessary? Most everyone else in the market recognizes their HD channels in their legal ID, even if it's on an HD1 channel. CBS Radio does it. Clear Channel's stations do it, too. Odd that ABC doesn't.
