Clear Channel announced in 2006 that KFBK would be converted from a
traditional AM broadcasting station to an HD2 facility. Eventually,
the HD conversion will allow for KFBK-1, KFBK-2 and KFBK-3 together on
the 1530 AM signal.

I didn't think you could carry all those separate IBOC services on the
AM band?

I thought IBOC for AM consisted basically of the station's digital
signal plus RDS, since there isn't room for anything else (unless you
turn off the analog signal).

IBOC FM, I know for certain, can support up to three or four
"streams". Maybe even more if you do away with analog subcarriers
(like 92 and 67 khz for voice) and the analog section of the signal.
