Your best ever car radio?

The technical side of broadcasting. Think IBOC is a sham? Talk about it here! How about HDTV? Post DX reports here as well.

Serious... It's you guys. (I'm the guy in marpat that you'll never see, the guy way off the trail, who's stealing orchids.) They had no real idea where they were moving to, and still think I'm joking about their local lake effect snow. Bob was chased off his back porch by a LARGE CAT the first month that they were there and Ann had her birdfeeders flattened. I had an excellent laugh with my wife's brother the DNR ranger over it.

It was the only time I ever experienced AM stereo. Why did the broadcasting industry abandon that mode?
A few reasons I've heard:

1. AM stereo was replaced with IBOC
2. Format changed to talk, no need for stereo
3. Coverage is lessened

4. Equipment failed and don't want to fix/replace.....
Fallacy!
They are confusing AM stereo with FM stereo.
In FM stereo, the combination of the main baseband channel and the ultrasonic L-R subcarrier forces the station to halve the deviation on the main channel and the L-R DSSC subcarrier.

Fortunately, for the generous bandwidth given to an FM broadcast station, the loss of signal in the main channel is marginal.

FM stereo, however, greatly increases the receiver bandwidth - greatly increasing the noise level (usually in the form of white noise).

In AM stereo, the carrier is still fully modulated. An AM station operating in stereo is just as loud as a monaural AM station on a monaural receiver. A regular radio is unaffected by the quadrature component.

I will concede that AM stereo operation made co-channel interference more noticeable when co-channel interference was present. Many Class C stations should have operated in stereo only during daytime hours, or avoided it altogether.

AM stereo was far more expensive to install than FM stereo, and, with few stations using stereo, many stations saw no benefit in it.

However, the real death knell happened when all radio consolidated from thousands of owners to dozens. This made it easy for radio ownership groups to collude, and letting all that AM stereo gear to die saved money.

Sadly, The U.S. radio owners took Canadian radio into the hole. With NAFTA, Canada (where AM Stereo had been showing great potential) became unavailable because the USA didn't want it.

This also killed Canadian DAB, as the powerful NAB was able to squash it.

The beats Audio package with the U-Connect in my Charger is the best I have ever had.

I guess I don't understand the point to the whole conversation about wildlife. If you know who I am then you'll know I lived in a national forest for over 10 years.

Ten speakers? That's a comb filter disaster. Only auto manufacturers do that. Yes...yikes, the idea is to do it with as few drivers as possible: physical arrival time issues cannot be fixed completely with DSP. Ten speakers means the system will not image for poop.

YOu say all this without hearing.....Must be great to know it all without actually sitting in the vehicle. There are 12 and 18 speakers systems out there too. Tell us how they sound without ever having heard them.

Yep...there are things that physics allow you to predict.

THIS is my Guru, Richard Clark and he's holding a custom tweeter from his GNX - the compression driver features a beryllium dome and the horn path lengths are different from right to left. Image

Car audio used to be a big thing and featured a lot of contests with a national sanctioning body and certified judging. A pair of electrical engineers with a background in Pro Audio, (Mr. Clark and his partner David Navone) got involved and began winning ALL of the contests for sound quality. After dominating the national events for 5 years, they released AUTOSOUND 2000 Tech Briefs and the rest is history. I was one of the original subscribers to the tech briefs and learned best practice in system design from Rich; they're still on my bookshelf.

In a nutshell, the idea is to minimize path length differences between speakers and reduce total speaker count.
My last set-up was Boston Pro 3-way up front with ZERO rear fill and a 15" sub that I sniped from Dr. Bruce Edgar.

We're talking about STEREO reproduction, what half-deaf oaf would locate speakers BEHIND the listener in a stereo set-up?

By the way...the sub from the car is now in the house. I built a custom enclosure for it and it's a part of my PC audio system now. The FET-500 is pushing around 800 watts into it. The guy on Ebay who lost the auction for that speaker was somebody. What would Dr. Bruce have done with it? Image
