should not write postings multi-threaded :-( The argument actually
mixes up two ideas; the first is that an AM
detector is too mediocre to most people nowadays who are accustomed to
FM stereo sound or even
5.1/6.1/7.1/whatever sound even with cheapest receivers.
Hey around here Am or FM is all crappy music, so even the $4.99 radio
sounds good.
The second point emphasizes on the
"digitalization" issue:
in the near future there won't be any analogue AM or FM
transmissions/transmitters any more; even SW band migrates
to DRM now - so success won't be reached anymore with the a variable
cap, a coil, a diode, a high-owmed head phone
and a reasonable long wire as the antenna. Surely there will be high
integrated circuit modules that decode all the stuff, but
electronics hobby is not really interesting when reduced to adding a
battery to a black box.
Xtal radio is making a come back.
