I generally avoid the IBOC discussions in this newsgroup, but it
appears that another 50 kW clear channel station has turned it off, at
least at night. WHAS (840 kHz) in Louisville, KY, has had their
nighttime IBOC turned off for at least the last three days. It's been
a great Christmas surprise to be able to clearly receive WCCO (830-
Minneapolis) and KOA (850-Denver) without having to tune out the
annoying IBOC trash.

Way to go!

Good news! Hopefully, it will be permanent! Clear Channel's Format Lab
HD2 channels is down to only 7, from 75, due to a lack of demand. For
AM-HD, more-an-more stations are turning it off:

"CC Radio’s Format Lab gone?"
November 2008

"So bottom line, the Format Lab is no longer available on the web and
has cut some of its formats down to the most successful/desirable. The
www.iHeartMusic.com website seems to only list the main audio streams
of CC stations--not multicast HD formats--but does offer a few off to
the side: erockster; Pride; Verizon New Music; Smooth Jazz; Real
Oldies; Slow Jams and New Country. There used to be something close to
100 formats listed on the site... Really, the next round of budget
cuts--out of necessity--is likely going to be HD Radio equipment and
licensing renewals. It has cost broadcasters money that so far has not
generated ROI. This CC Radio news above, along with the rumors that
Citadel has told Engineering not to fix any broken HD transmitters on
AM, may be the tip of the iceberg."
