What mode were they using at the time?

Magnavox, but with a 25 Hz pilot tone added, to fool C-Quam receivers into decoding them in stereo.

To return to the thread of this discussion... at least briefly... WSCR 670 and WBBM 780 both appear to have their IBOC turned off at the moment. I thought maybe it was just for a game, but it has persisted overnight and this morning. Both sound so much better without the annoying hiss in the background!! Enjoy it while it lasts....

It appears that WNYC 820 has turned of the whoosh generator.

Both off all day Sunday, and still off when I went in to work tonight.

Listened to wonderful old stuff on WSM all the way to work.  Smiley

A quick check now still shows no iboc on either.

WTAG 580 5 KW has been off again for the past several days, it's a day time only hash pumper anyway but the IBOC is off quite often on this station so I'll wait a while before I email the engineer again to see if it's permanent.

Did the apparent width of the digital sidebands change any?   ( As in WSCR/WBBM)

Well it's hash machine is still off, I'll keep checking and I'll report back when and if they turn it back on.

Honk, Honk.    Honk Honk!

Your idea of radio is a weak, small-minded little concept, and far outside the protected contours of the laws of physics.

You can try all you want, but skywave is real, and doesn't respect any definitions or excuses that it "ought not exist".

You are still free to create as much interference to the public airwaves as you can get away with.
Have fun at it, you wild-n-crazy guy, you.

HD on AM is about as effective as the glue used in the roof panels of the "big dig".
"But they said this glue would work!"

Unless of course the idea is to trash the service, then it's doing a pretty good job.

All of you seem to be missing the main reason people don't care for it.

It requires too much babysitting. There is a delay which is established on the digital side and becomes more apparent the longer it is not adjusted. It also is obvious which stations those engineers listen to.

How long is a normal listener going to put up with a 3-10 second delay shifting back and forth before they find other ways to enjoy their listening by other means other than OTA radio?

In short: It is an unstable system and too obvious to the listener.
