#1 reason is the Antenna. #2 cost is king!

Car = antenna on AM & FM

Home radio = Bar antenna on AM and ? what on FM... Sometimes it is the
power cord. Sometimes you have a wire to drape over the lamp shade. The
aluminum backing on house insulation can provide some attenuation effect,
but I'm sure this is less of a factor...it is the primarily the antenna.

Car radios on FM do not have exceptional selectivity as speculated above.
The adjacent channel selectivity is only fair and the systems are made to
only use alternate channels in any one market, anyway. When you're between
markets and have a weak station 200 KHz away from a strong one that you have
trouble. If "they" wanted better performance @ home is could be done, just
costs $$. Low IF for reduced BW can be done in any radio, but size and Q
and frequency are not independent, so lower freq IF means bigger coils and
more "R", so "same Q - lower IF" is not that simple.


Did you hear about that guy who changed his name to "They". Interview on
pub radio this weekend.

...
as compared to my home radios/stereos?

All--

Have wondered for years why this is so--almost w/o exception,
on both AM/FM. On the car NGs, it was suggested that my house was
blocking
signals, and that the metallic car acted as a big antenna. Neither seems
plausible, as my car next to the shop radio (which is terrible) still gets
good reception, and that if the metal in a car were so good, you wouldn't
need a car antenna.
I'm thinking it's the actual electronics. Any
opinions/explanations?
