Car stereo for FM Selectivity

J

JerseyShor

Among CURRENTLY AVAILIBLE after-market car stereos...

I've seen Alpine claiming 80dB selectivity
I've seen Pioneer claiming 80dB selectivity
I've seen Sony claiming 75dB selectivity

Pioneer is offering the "Supertuner IIID" with adaptive reception.
Sony is offering the "SSIR-EXA" with adaptive reception.

So my question is: Who's best in the real world?

Who can really "dig out" first adjacents the best?
 
Check a few threads down for more info in this
 
The Pioneer SuperTuner IV was the finest, most selective FM mass-produced radio ever built. The new Pioneer stuff is ok, but not NEARLY as selective. One of the best radios I've found being made lately is the bose-delco stuff in some of the newer high-end GM cars and trucks. They are fairly close to the Pioneer and actually blend-to-mono much better. But, if you're looking for the most selective and best DX box for you car, keep searching for the SuperTuner IV. You'll be shocked how well it will work for you.


;D
 
Where can I get info about getting a Super Tuner IV can not seen to find much on the net
 
I have a Blaupunkt Richmond from 1982 (totally analog tuning) that I am still impressed with for AM and FM selectivity.
The stereo blend is variable, and never detrimental to listening.
The selectivity compares to the best Bendix and Motorola radios of the discrete-component era.
It regularly picks up Michigan FMs in Chicago.
And it has National Semiconductor's DNR ( Dynamic Noise Reduction) switchable, which removes ALL hiss from FM, AM or cassette.

DNR is an example of a fine technology fallen by the wayside, like AM stereo, which worked pretty dang well, but never became a standard.
