   Not to worry, the FM stations will get new equipment real soon and address   
   that so that they can come closer to an aspect ratio of zero or less.

   At home perhaps you can try get away with installing an attenuator in the 4   
   to 6 dB range inside the contraption, but I wouldn't even consider trying   
   with a car radio, those likely have their innards compressed to a negative   
   aspect ratio and you will not bee able to make them fit the case if you open   
   it.

   Very many years ago some design contained sensitivity trimmers to make the   
   phono input match FM, my Beomaster 3000 was like that, including   
   balance-matching via nulling of inversed channel

   If so it is called "night" or similar. We can not have the populace   
   understandin this, so we call it something else.

   FM statios are voiding the headroom asumption for clean transmission that   
   the tuner electronic designer made because it was in his textbook. He should   
   have desined for 5 dB transmission malpractice. Orban is not to blame, he   
   quite probably warn them in the manual. From the sound of some of the louder   
   FM's over here they first max the 5 band, then hit a multiband clipper and   
   then push it well into the tranmitters protection limiter. All have   
   hideously audbible compression artifacts that stand out obnoxiously on even   
   the poorest possible playback equipment but can become impressively loud on   
   a JCV loudenboomer hung on a warehouse wall with volume set to 11 and   
   beyond. And thus the FM stations aim is well and truly met, because THAT is   
   what they aim for.

   I must have some kind of mind damage from working with printing machines for   
   so many years, I tend to solve the problem by turning the car radio off and   
   just listening to the car. Perhaps I should resume my venture into   
   avant-garde techno ... a computer harddrive died during a file-shuffle with   
   all my music on it back in 1997, and I just haven't bothered to retrace ...   
   was in a large rythmical structure being built to support ephemerial synths   
   when it happened. I made a "In C" rendition in DeLuxe music on my Amiga, I   
   had it as midi dump, but now only the DAT tape of the Amiga sound systems   
   performance of it remains ....
