WHAS was off the air early this morning only to return with the IBOC noise grinder back on. For over a year, they had it turned off. How long will the FCC allow this intentional interference to traditional analog broadcasting continue? It is most destructive to those who want to listen to stations on 830 or 850 at night.

In Case You Didn't Notice --- IBOC back on WHAS!

I hate it, I'm trying to listen to 750 at night in Vallejo..
I could null out KCBS noise on 750, but not by much.. I have to null it right to hear something on 750
730 is bad..I can't even null it to hear anyting on 730

I agree with all of the anti IBOC people here. I understand why they're trying to do it, but I don't understand the point of having it on AM when most co-owned FM stations have HD and could utilize one of those HD-subcarrier channels to put their AM product in HD-FM!
Something ain't right when WBZ's IBOC effectively renders KDKA and WHO unlistenable in Southern Michigan! Boston is over 700 air miles from here. One has to wonder how close to Pittsburgh you can be and still hear hints of 'BZ hash on KDKA.
As for WHAS, they didn't seem to be doing much in my location last night. I did notice the IBOC, but it was nothing like the great wall produced by 'BZ. 830 and 850 are pretty much shot now to the south, but pointing the radio to the west, WCCO and KOA were punching right through it.

Yes they are and their meat-grinder is interfering with KOA and WCCO here in N. IL and must now be nulled.
And, to Lawppy's comment, the idiocy of AM HD is exemplified by the portion of the band between 1000 and 1100 kHz in the eastern half of the USA. It is M.A.D. on all frequencies. From the Chicago area, KDKA is sometimes blotted out by WBZ which is sometimes blotted out by KDKA and/or WHO which is sometimes blotted out by WBZ. At times, you can't listen to any of them, nor to anything on 1050 or 1010.
This is a travesty. But I am pissed with WHAS. What, realistically, can we do? Can we file complaints with the FCC? That way, they can't justify stupidity with the statement: "duh, we haven't received a single complaint."
When tuning to a station next to an AM station with IBOC, it may be possible to tune a little bit toward the IBOC station to hear the desired station a bit more, with an analog radio or a table top SW receiver with either a RIT control or the tuning knob, or any radio with fine tuning. I find that there is one spot where the hiss may be lower. On radios like the Sangean PR-D5 it's not possible with the 10 kHz tuning. In the case of WBZ, it would be harder because its hiss machine is so loud. Appears to be same thing with WGY and WCCO when trying to tune in 820.
I've done this fine tuning and had some luck so far.

I live 55 miles from Pittsburgh and there's no hint of KDKA on 1020 at night thanks to WBZ's IBOC.
Here in Lexington, I can null out the IBOC Interference and get WCCO on 830 at night, but can no longer get KOA on 850. Both KOA and WHAS are in the same direction from me...
I call IBOC "interference" because that's what it is. Digital and analog modes are not compatible on the AM broadcast band and to all those IBOC LOVERS, PLEASE don't tell me I have no business listening to KOA anymore!

I'm guessing WBZ is blasting to the west of Boston,
that's not right no one could hear KDKA 50 miles out of Pittsburgh

WBZ with that directional pattern has always been the strongest east coast station in the Midwest and they're much stronger than KDKA.
During darkness hours, you start to hear WCCO's IBOC garbage behind WHAS at Scottsburg,IN...29 miles north of the Louisville city limits.

Can KDKA do anything about it??
I heard my first out of state IBOC hash this past Saturday night; WHAS's noisemaker kept me from receiving anything on 850. I was about 50 miles due east of Orlando and normally in that area a blend of WFTL - West Palm or WRUF - Gainesville, but neither were to be heard due to the IBOC hash.
When in St. Petersburg, the only night IBOC hash I hear is 1380 - WWMI-Radio Disney, which is the only IBOC station in the Tampa/St Pete area that employs the IBOC jammer 24/7. At night in St. Pete I can't receive anything on 1370 or 1390 and during the day 1360 and 1400 are wiped out as well.
