Most US car radios allowed the adjustment by removing

My V expensive Blaupunkt doesn't have an aerial trimmer - nor have I seen
one for many a year. Thought most had some form of automatic matching
circuit these days?


Fancy words for a little more stage gain and lower performance. They
did that because most people were too stupid to adjust the trimmer
properly, and would return new radios as defective. Newer car radios
are crap when compared to the earlier designs, if you want to listen to
a weak AM station.
