Well put...a solution looking for a problem...that echoes my sentiments exactly. With AM being dominated by Talk anyway, who the heck needs stereo?

AND...I can't see paying someone(Ibiquity) for a licensing fee to broadcast in stereo, that's just plain shameful.

AND...I like things just the way they are, with 7.5 Khz wide audio that is intelligible...not that muffled 5Khz stuff I hear on the local IBOC stations.

Hot Dang!

Thank you. Actually, there are quite a few AM Stereo music stations. For Talk, AM Stereo would allow some interesting variations, such as having the talk host's voice on one speaker and the guests and/or callers on the other. It would sound like they're sitting across from each other on a sound stage. The speaker the host is on (left or right) could follow his or her political affiliation. :)

Yeah...A C-QUAM AM Stereo exciter is a lot cheaper, and it's only a one-time expense unlike the IBOC licensing fees.

That goes along with another one of their claims--that IBOC will provide more channels. While that's true, each channel will have narrower audio bandwidth and will sound worse. Since existing analog FM sub-carrier (SCA) channels are so under-utilized, who needs the IBOC? (How those narrow channels would sound on AM would probably make Marconi blush!) There's only so much programming content out there, after all. -- JasonW

I bought Chris Cuff's C-Quam decoder (25.00) and installed it into my Sony GX50ES stereo receiver. It works great.

I just need more AMS stations to use it with.

WLS is still in AM stereo. I was in Chicago last week and the stereo light lit up. WOKY in Milwaukee is still in stereo as well and they sound GREAT! If you have never heard AM Stereo you will be surprised -- as long as you haev a decen AM stereo receiver. SOme of the DElcos are crap. Most of the Chrysler products are OK Fords are the best! At our stations we have an 02 Ford Explorer that has a AM stereo radio that adjusts the bandwidth according to the signal. What a nice radio!!
 
Re: good points except...

My question is -- Have you actually HEARD HD Radio?? It would appear that the bit rates are too mow to provide decent audio but from what I have heard they have done a good job with the CODEC. I am no huge fan of IBOC, but HD Radio does sound decent.

For politicians. So they can talk out of both sides of their mouth, and when neccesary use Platform Shift to their advantage....

This is bovine excretion. There is no loss of coverage with C-Quam. I took careful measurements of KMKI under controlled conditions with calibrated equipment when they were C-Quam, mono AM only, and when they transitioned to IBOC. Field strength measurments at a dozen locations from 10 to 300 miles out showed no differences beyond those that are statistical.

The only drop in coverage I can document is FM IBOC - and I am in the process of making careful field strength measurments on a station that I anticipate will go IBOC shortly. I srongly suspect the loss in coverage will be dramatic - based on unscientific results on other stations. As much as 50 to 60 miles of coverage lost.

This says volumes about Ibiquity. They know they have a white elephant - they want to get a load of money fast before the whole thing collapses, you will be stuck with orphan equipment, a smaller bank account, and a few dozen digital listeners if you go digital.

My sister in law knows nothing about HD radio. But she does know that her station quit running RDS song titles on her radio. And that now there is picket fencing and dropouts on her station that weren't there before. These are both "advantages" of IBOC.

With consumers keeping their cars longer and longer - an average of ten years - it will take a long time for C-Quam AM radios and RDW FM radios to disappear. Replaced by, for the most part, satellite capable car radios and sound systems allowing inputs from iPods and DVD players. Be afraid. Be VERY afraid!

What are they smoking? Did they pull a Rip Van Winkle or something? AM stereo has been dead for 15+ years. No one but a few radio geeks cared in the 80s, no one cares today. Just what the public has been clamoring for...electrical noise in stereo.

Are any of these receivers still being built? Have any cars built in the last 8-10 years come equipped with AM stereo radios, or will you have to pick up that '88 Dodge Omni with one brown door at Honest Eddie's in order to hear it?

Ford's Premium audio systems still include AM Stereo. There are millions of AM Stereo-equipped receivers in the marketplace today, and smart stations continue to make use of it, despite nay-sayers like you whose "AM Stereo is dead" mantra is just as stupid and incorrect today as it was a decade ago.

Besides the Ford Premium, I don't know of any new AM Stereo receivers currently domestically available. Who else is still currently manufacturing them?

All of mine were old ones purchased on eBay.

There are still two AM Stereo stations hanging in there in the Boston area.

WJIB 740 AM Cambridge, MA (Adult Standards) still broadcasts in full AM Stereo 24 hours a day. It sounds great on a wideband AM stereo receiver.

Their 250 watt non-directional day power covers the greater Boston area, mainly within Route 128, surprisingly well. At night (due to 50kW CHWO Toronto which is also Adult Standards, but in mono) WJIB goes down to just 5 watts which only covers the immediate Cambridge/Downtown Boston area and a few adjacent north/west metro suburbs, but it's still in AM Stereo.

Also, WLYN 1360 AM Lynn, MA (brokered ethnic) is still in full AM Stereo on their 700 watt daytime power only, which covers from Boston's North Shore down through the city, and across Boston Harbor to the South Shore. Their 76 watt nighttime signal, mainly limited to Boston's North Shore, is mono.

40 miles west of Boston an AM Stereo pilot can be seen on 5 kW WVEI 1440 AM Worcester, MA, which is a relay of mono sports/talk parent station WEEI 850 AM Boston.
 
Re: good points except...

Sorry about posting so late, but I just found this thread.
Regarding CQAM reducing a station's coverage, here is my experience, using several multistandard units as well as dedicated CQAM units. There is no way your field strength can change one bit, however:

If you transmit with asymetric modulaton (130% positive peaks) some or all stereo receivers will sense that the balance is shifted to (I think it is) the right side. In order to keep all stereo radios from sounding louder on one side than the other, you must transmit symetric modulation with no positive peak enhancement. The issue here becomes that you loose from 15% to 30% loudness (especially) in monaural radios by not enhancing those positive peaks.
This was never an issue with the K-H(ISB) system I loved so dearly.<P ID="signature">______________

Our local Class I-A (I'm sorry, Class A) WCCO/830 opted for IBOC a few months ago. They now sound no better on my GE SuperRadio in wideband mode than in narrow. Either way they have a very harsh sound caused by the steep 5 kHz filtering, and not just on the GE, but on both my GM auto radios (not wideband by any stretch).

I'm old enough to remember what most AMs sounded like back in the 50s (5 kHz telco lines to the TX), and if anything the current incarnation of 5 kHz AM sounds even worse than that, probably because the filtering back then wasn't so brutal.

The thing that ticks me off is even at night when WCCO is not transmitting IBOC, they still brute-force filter the audio. I used to enjoy listening to "Imanigation Theatre", a recreation of radio drama, although with new scripts and obviously, modern recording tecniques. These shows sounded great in wideband 10 kHz audio, but now sound like crap. I no longer listen.
