So has anyone other than Kahn heard his system for digital?  The problem with that guy in my opinion is he's real good at spewing how great and superior his stuff is, but he doesn't give enough of his precious information out so that a guy can consider his products much more than vaporware.  AM IBOC is a joke.  I actually hope Kahn has something worth trying.  Wouldn't it have been smarter to just ask for channel 6 when analog TV goes away for the AM IBOC simulcast utilizing the FM standard?  Wouldn't it be worth waiting for?

It's a sad day that no one pays attention to when you can joke about no one listening on staff and everyone can relate.

Two AMs in SETX are running his system....they sound like crap in analog at times (cant say what the digital sounds like since there are NO rcvrs for it)
DRM has been approved for SW....why not for AM?? Could it be because a lot of cash has changed hands??? HMMMMMM could be!! Ibiquity has too much invested in IBOC now...but DRM works and works well!!Kahn's system is an expansion of the ISB/Powerside system..evidently the underused sideband is the one that carries the digital info.....nice idea actually...but WHO has a rcvr for it? noone I know of....Kahn is a great engineer...but his ego and his lack of personality is what did in his AM Stereo system (that and his refusal to allow anyone else licensing rights, etc....GEESH)

My understanding of DRM is that you cannot have analog and DRM running at the same time.

The biggest mistake that we did in this country was insist on IBOC. The European and Canadian Eureka system is simply superior -- although the British are using ridiculously low bitrates in order to multicast.

Now that you mention it, I remember that from high school and before.
Walter Cronkite in monochrome. Sigh.
We got our first color set in I think '64 (I was 13).

When I started in TV it was already '85 and we had a bunch of F.S.
and the metro's first C Band uplink.  We did everything coming out
of Portland for all the networks back then.

Good grief. Even you!! Nah, just kidding. If I could have gotten in
I would have.  Nowadays, at 54, I can't even buy an interview with
the big boys. No sales experience. No inside connection. Poverty soon!!!

No. Do I want to?

Vidifont Mark II (or III?) was the oldest box when I got there.
What a rattletrap!  Font operators never spelled anything correctly anyway!!!

DRM has an analog-compatible mode, at the expense of reduced data rate.

More details at: http://beradio.com/iboc_update/iboc_update_052604/

From what I have read about Kahn's CAM-D system, it uses a low-data-rate digital stream to carry high-frequency audio content.  This somehow gets added to the 8 or 9 kHz analog audio in the main channel.  Nobody knows for sure except Leonard, and he's not giving out any technical details.

Which you KNOW we would have done the same thing.  

The thing with Canadian Eureka, is that it is failing.... no one is using it.  This according to an engineer aquaintance of mine in Canada.

I sold a few of the very first ones made by NEC...close to,
or just over, 100-grand each at the time!  Thousands of
chips, each one 16 bits.

With the atmosphere in that side of the business now, and the
foreign ownerships, you're better off staying out of it.  I
was somewhere between smart and lucky and grabbed an early
retirement around 1995.

If you ever worked TV.  It started with the Model 300.  Up to then,
on a 3-M/E switcher, M/E-1 re-entered M/E's 2 and 3 and Pgm/Pst.
M/E-2 couldn't get back up to 1; 3 couldn't get back up to 2 or 1.
The first pass at manufacturing the 300 allowed any M/E to re-enter
any other, up or down.  (M/E = Mix/Effects System, wherein one
selects sources for transition, keys, mixes, wipes, etc.).  In
reality it violated the laws of physics and only a handful were
built.  The whole project was redone in a more conventional way,
but still allowing unlimited re-entry but at the expense of
incredible throughput delay.  All the originals were recalled and
replaced; there was very little that could be salvaged from each.
Important point was the company stood behind the product; how many
do that today?  I can think of maybe three....

I survived the very early Chyrons (when they spelled it "Chiron")
which were programmed by means of front panel toggle switches.  Then
"Compositor I" which was programmed with paper tape and whose
"brain" was a PDP-11 board.  Also a generation of TCR-100's...the
version that left NO room for fingers between bins and could do
amputations at battlefield speed!

It was my observation that CG operators didn't so much not know how
to spell as preferred NOT to spell properly.  Other retaliatory
trick:  Chroma key out the eyes of the late-night anchor and fill
with flames from stock film footage.  Delicate work but worth it
to bring to the anchor a truly satanic image!  Or to change the
color of the anchorette's dress so it clashed horribly with her
hair.....

We're getting old!!!

Our sales people love to sell remotes in locations that are not accessible by Marti, nor have any kind of land line already installed.  Too expensive to spend several hundred dollars to get a line installed for 6 /2 minute drop-ins in the typical two hour remote.  Sometimes cell phone is the only option.

I've re-wired a hands free headset/mike combination to replace the little condensor mike with an XLR.  Works fine with a Motorola V-60 cell phone, providing that the dynamic mike has enough output to drive the phone.  E.G.: an EV 635 or RE-16.  As long as you are in a relatively quiet (ambient noise) area, sounds no better or worse than any other POTS remote.

Works fine, that is, so long as you don't have to get off air cues at a remote.
Like the "Ellenboro Glass Festival" we were promoting yesterday. Our Ops manager is doing the remote, for some reason scheduled for between 9 and 11 Saturday morning. (Which was probably too early Satuirday morning for him, he DJ's Friday nights).  We have speakers on the remote truck, but there's too much delay through the digital cell phone network to listen off air.

He has to fill a 2 minute local hole before going back into satellite music programing. He misses the music coming back up. Next thing we know, it's a six minute break.  Sigh.... at least the sponsors got their money's worth!

Everyone complains about radio being canned nowadays, but we keep moving towards technology that demands a pre-packed product.
