Sony makes a car stereo system that includes shortwave radio. How well does
it perform? Would I actually be able to hear at least the major
international outlets (BBC, RCI, etc.) while driving across town?

I'm a ham and have been an avid SWL in the past -- away from it recently --
but am also a linguist and would like to hear various languages regularly
(including something in Spanish with more intellectual content than the
local hit parade, or whatever it is). I understand that this radio would
not be for serious DXing.

Any experiences? Thanks.
