AM HD TURNOFF PACE ACCELERATES

You are perceptive indeed. The iboc raises the noise floor across the entire band in a minimal but noticable way.
The sidebands trash the 20 khz above and below any iboc stattion for a distance about twice the listenable radius of
the signal.

WSCR 670 continues to soil its own undies and blow excrement +/- 30 khz outside its panties.

There really is a classic ( distorted) image response off the digital sidbands.
You can hear the analog at 640-ish , as a reflection from 670's lower sideband "digital constellation".

640 in Wisconsin is totally wiped today, WSCR sounds fully as hobbled as WBBM.
And in my car radio, either one is critical to tune without birdies. Look it up if you don't know what birdies are.
 
To go further on my previous posts in this thread...

WPLN-AM (Madison, TN) still is absent of the hash as of last week. WPLN-AM is a NPR affiliate. To date, HD has been off for about a month and a half. They broadcasted HD 24 hours a day.
 
Brought my gear down to Syracuse, NY today. The good news is I can report that Radio Disney station WOLF-AM 1490 is not running HD. Its possible they never ran HD as this is a non Disney owned affiliate.

The bad news is nobody is running AM stereo anymore. I hoping WSEN 1050 would be in stereo since they are still a music format and once ran AM stereo according to various websites I've seen them listed on.

WOLF was a very early adopter of AM HD, Disney-owned or not. It was definitely on the air for quite a few years there.

Maybe its temporary then, the audio still sounded pretty narrow on my other radio. 1490 is very weak up where I live so I've never had a chance to check it before. I can usually only get them via groundwave during the winter. On the FM side WOLF 105.1 is broadcasting in HD with 2 subchannels.
 
Well I've been out of the country for 6 weeks now and can't wait to get back and see if my local whooshmaster WTAG 580 is still obliterating it's adjacents for no reason at all.

Yes it is dropping, what it doesn't say iis that there are only 197 total listeners.

I would love to listen to a big news-talker in my area (Sacramento) but the sound when it blends to HD is so shrill, I have to turn it off. Thankfully, they added an FM so the issue is moot. On a side note, Radio Disney seems to do a nice job with their AM HD -- at least in this market they do.

The sound was also very shrill here on WBZ, very unlistenable.
 
I have to hold the antenna in just the right way to get AM in HD in the daytime, on a local station. And it won't even stay locked. I tried for an hour to get ANY AM station in HD at night with no luck. Couldn't even see any call letters. I tried with a longwire, unplugged other electronic devices, and even brought the radio outside. The best I got was the HD light flashed. The average person will not do what I did to get AM in HD.
 
Well, we are now down to 196 AM stations broadcasting in Horrible Distortion. Looks like a couple of preteen stations have dropped it this month including KDIS 1110 Pasadena and WWMI 1380 St Petersburg. I guess even kids are getting sick of the noise?

My local noisemaker WTAG 580 has been off for a couple of days now, this will be back to pollute the airwaves soon though, it is off and on constantly in a tribute to the rock solid consistency of IBOC broadcasting.

KDIS still runs it, but only in the daytime. At night they shut it off and open the analog bandwidth to the full 10 kHz. (Unfortunately I didn't hear any separation on my SRF-42 when I was up there a few weeks ago visiting my grandma a few miles west of the transmitter.)

Sounds great to me. Listen all day in the office on HD.

Well, that's wonderful. I'm sure you alone somehow offset several dozen suburban listeners who have given up
listening to WBZ because it's too hissy now.
