Countdown to the end of the Universe

I wish any AM well and success, especially an anchor of the industry like WOR. I just wish it's new technology wouldn't hurt others.

W=690Kc
WO=700Kc
WOR=710Kc
OR=720Kc
R=720Kc
 
O Boy! Cookies and Kool-aid!

I can finally use solid core spark plug wires!

Can't wait to build a wideband 540-1700 noisebox to improve the noise floor even more.
I may run a Jacob's ladder contiunously.
Now, back to winding that tesla coil.
Where's that old electric fence pwr supply?

If noise is good, then let's all make lot of it.

or a line from some movie I can't even identify, but remember well...

" If they've got bayonets, We've got knives!"
 
Quoting Clear Channel's Jeff Littlejohn:
Concerns
The current AM allocation rules require Co-Channel stations to provide 20:1
protections to each other and first adjacent channel stations to provide 2:1 protection to
each other. While this works fine in an all-analog environment, it does not seem to be
sufficient in the presence of IBOC. The energy above 10 KHz from the proposed Hybrid
IBOC signal significantly exceeds the energy present in the current analog AM signal.
For this reason, the amount of energy provided to a first adjacent station is significantly
more detrimental than our current allocation rules allow for.

Special message to our Canadian and Mexican friends: please feel free to complain LOUDLY - you know, kind of like "an IBOC sideband" - about the horrific adjacent channel interference to your domestic AM stations. Gringo stations stepping all over your sovereign broadcasts! Are you gonna just sit there north/south of the border and take it? Don't wimp out! Stand up and fight like men! And women!

Just wait until CASTRO gets a load of gringo interference. You have any doubts about his reaction, just listen to the 1181 kHz jamming signal on Radio Marti. We put our hash over his island, remember what he did a couple of decades ago! I'm just going to laugh if he rains on HD radio's parade.

Yeah that would really be funny.

Kinda like driving off in the car when a dog is tied to the bumper.

Ha ha

Naw, that's not funny. Leave the dogs alone. Driving off with Bob Struble tied to the bumper - now THAT'S HILARIOUS!

So Littlejohn's evaluation of IBOC nighttime interference is five years old? So, what - that means it's no longer valid? Did his conclusions have some kind of expiration date? Anyone characterising the 2002 report on HD-AM as "supportive of the system's universal implementation" is torturing logic to support an erroneous and self-serving interpretation. Any objective reading of that information would view it as "guarded" at best. It is also significant that Littlejohn has been notably silent regarding HD-AM lately as the debate increases in intensity, instead of abating.

dbdigital has an excellent point. If IBOC-AM was such a great idea, any rational radio professional would immediately embrace it. The fact that there's any technical debate AT ALL - much less the current roar of protest from thinking persons in the industry without a pro-HD agenda - indicates serious problems. Then there are the little matters of warnings from Mexico and Canada about potential treaty violations. The public comment for the last R&O reportedly ran 4-to-1 negative against nighttime IBOC implementation. Yet the Commission approved it - and some scoff at the idea that "nobody got to" Commissioners??

The same Mexican government that does nothing about this? http://www.well.com/user/dmsml/xlnc/xlncpics.html

In Mexico, if you grease the right palms you can get away with anything. If any complaints come via Mexico, iBiquity clearly didn't pay off the right people.
 
I hope WOR's audience likes listening to telephone-grade audio. If, for no other reason they should cringe at the thought of running audience off thanks to the crappy analog audio.

Oh well...

Let the hissing begin!
 
Savage thusly spake:

Yes, the image of that is pretty funny!

Since someone mentioned that Mr. Littlejohn's employer has embraced this technology, it is quite likely that he is no longer able to express his honest engineering opinion because it would go against his company's mandate. That's too bad. And that's also probably why we hardly hear from ANY AM engineers in the trenches who have been ordered to install this equipment.

Tom Ray: Where are you now that we really need you to guide us to the fountain of youth for the AM broadcast band? We need a good reason to go out and embrace AM HD. You have not yet given us one, but I would welcome any positive comment from you indicating that this is a really GOOD thing for the AM broadcast band.

dbdigital has an excellent point. If IBOC-AM was such a great idea, any rational radio professional would immediately embrace it. The fact that there's any technical debate AT ALL - much less the current roar of protest from thinking persons in the industry without a pro-HD agenda - indicates serious problems.

I am glad you are realizing this. I thought that I was the only one. No doubt, the lack of engineering accolades here is deliberate with the hope that people will sit up and take notice. The silence from those who might say that this is the next greatest radio broadcast innovation since the invention of the FM discriminator is deafening.
 
Last I heard it was actually Al Kenyon, Clear Channel's Senior VP of Technology. Unless he was one of the recent hundreds of CC executives who got the ax to - say it with me!! SAVE MONEY!!
 
It is sad that management types often dictate what technologies will be applied,
I am obliged to fix many items I would rather never existed. Mr Littlejohn is not free to voice his
actual opinion, but must be circumspect in his words. I am pleased to know his earlier
opinions were at best hesitant toward the AM HD.

CBS' AMs here in Chicago, (780 and 670)have not run iBOC for more than a few days now.
I have been preoccupied in the past few weeks with my father's passing away,
so I haven't been counting.

Maybe the whole thing really will fade away, like when the universe gives you a hairbrush after
you've gone bald.

This is an well-researched analysis. I also expect major problems to be caused by KYW (DA-1 with a lobe towards Toronto) to 1050 CHUM in cities on the back side of their night pattern, such as Hamilton.

The pro-AM-HD crowd constantly reminds us that "AM skywave coverage is no longer relevant in 2007", "there's no money in night skip or DX listening", etc.; therefore we can leave the hash generators on at night and everything will still sound fine to in-market listeners. Apparently, they haven't grasped the fact that the problems will be LOCAL; McLarnon is talking about interference to nighttime GROUNDWAVE coverage.
