HD is not yet authorized for night operation, although 4:30 AM falls in the
experimental period, so they could be testing.

WABC-77 AM (along with WOR-710 and WFAN-66 AM) shuts down the IBOC down
for the night.

WCBS-88 AM, however is running it 24/7. I guess they're experimenting
interference with WLS-89 AM,Chicago?

WNYC-82 AM was running IBOC day and night for the past month (10,000
watts day, 1000 watts night). The exciter has been off since this past
Friday night, however. As of this morning, it was still shut off.

WADO-1280 AM's exciter has also been off over the weekend. I don't
know what happened this morning, though. Didn't tune in.

So I don't know what's been happening...aside from LOTS of hash in the
daytime.
My Tivoli-Model 1 is now useless on AM in the daytime. Go figure.

I'm still waiting for WINS-1010, WEPN-1050 and WBBR-1130 to go
IBOC...maybe in a few months time? Ditto the regionals (WPAT-AM 93,
WZRC-1480, etc.), although those were playing with IBOC back in 2003
and then shut it off, never to turn it back on.

Salem Broadcasting (WMCA-57 and WWDJ-97 AM) are holding off on IBOC for
now....
