Local AM radio Audio Quality

[MichaelRivers]

I've noticed that the Clear Channel AM talk/sports stations: KLAC, KFI and KTLK sound like their audio is being sent to their respective transmitters via a narrow telephone line.

Compare the Audio of KABC and KSPN vs. KFI, KTLK and KLAC.<P ID="signature">______________

I believe all are limiting bandwidth for HD Radio, whether currently activated or not.

That makes sense. The only I question is why I don't hear the same lack of quality on KCBS-740 in SF. I thought they were already testing IBOC.

No it doesn't HD radio is a flop. Consumers never got
the memo. They won't buy it, it's nothing special.
AM already has enough problems, much less this.

And remember not all engineers have great ears.

Love that AM stereo and quad stereo equipment though .

Receivers are just recently starting to trickle into the market. This is a multi-year plan. Nearly every competitive rated market station is either implementing (500 on air) or has signed with iBiquity (over 2000 more)to introduce HD over the next few years.

I'm crazy enough to bet AM Stereo would probably be better/more quickly received by consumers today than HD Radio would. And the price of receivers wouldn't have to 'come down' from $500 or higher.

Maybe.

And seriously, I loved AM stereo in my old Toyota Supra. Just loved it.

Can you find ANY AM stereo non-vehicle receivers now.

The Sony SRF-A300, SRF-AX51V, and SRF-AX15 are AMS, at www.audiocubes.com

disclaimer: I don't have any of those, but I do have an SRF-42 and it's quite nice, except the tuning knob is funny on it.

Unfortunately, though, KDIS is now IBOC, so I can't get them in C-Quam anymore obviously (and even when they were the signal was marginal at best.) Now, to get the format I want to hear in AMS, I have to settle for a 0.02uV/m groundwave signal next to a ~8mV/m signal 10kHz higher, with a ~100uV/m co-channel signal the opposite direction from the desired station. Any suggesions on an antenna to get the Denver disney station from San Diego? I think that's the only AMS disney station that with a good antenna I'd have any hope for any chance of getting a round-the-clock reliable signal.

KCBS is an Infinity station. Only Clear Channel (and a small handful of other companies) are limiting their AM bandwidth. They've rolled it back to 5 kHz.

HD is not dead.

May I point out that FM took nearly 20 years to gain critical mass in the listening market, and another 10 to become dominant.

Typical American boomer, aren't you -- want everything right now!!
