 MR> James,

Bonjour Montreal!

With their lack of regulations, or policing of their power, I suppose
Havana can entertain most of Florida, unless it is jammed at the border.

For me, the Dodge camper-van was wired with a highly sensitive AM only
radio, and being a '70 vintage, places it squarely in the discreet
component (Maybe in the FET?) era device. When on the highway, one is
always looking for some entertainment, and scanning the waves.

It can be quite the hoot to log some of the stations one can find, and how
moving can affect the signal.
