As of 1 PM EDT, I'm hearing the IBOC HD radio sound on KYW 1060 AM. Don't know what time exactly did KYW changed its signal from analog to digital but it took place this morning.

Is further delaying the analog audio (news) about 8 seconds to sync with the digital a good idea?
Wasn't stereo news tried and discarded back in the C-Quam AM stereo days?
Is brick wall filtering KYW's analog audio to 5kHz just to accommodate an insignificant number of HD radio listeners rational?
AM HD stations analog 5 kHz audio suffers, sounds nasal, and full of artifacts, compared to high fidelity AM (non-HD) stations.
The all night AM HD radio buzzfest will likely start in July, I hear.

Sure enough, by the atomic clocks in my house, KYW newstime at the tone is now seven o'clock and eight seconds.
Just curious: Why is this happening with the switch to "HD"? Is this something they'll eventually be able to fix?

The encoding of analog audio(like speech) to digital(to transmit), and decoding digital to analog(so you can hear it) takes about 8 seconds. The standard analog audio for standard radios is purposly delayed so when the HD user receiver blends or kicks back between digital interruptions, or weak signal areas, to standard analog, the audio will have continuity. Same on FM...also delayed.
Oh migod that came out complicated...someone else wanna 'splain.

Actually, I kinda understand that explanation. Thanks.
The second part of my question still stands: Will they be able to do something to counteract this so the tones don't happen at the top of the hour plus eight seconds?
