The 50's vintage is what I remember Ralph.
<div>I was too young to understand the physics but I remember dad
mentioning about the wiper speed varying with changes in RPMs which of
course changed the vacuum level.

Hi Joe,
Older cars, back in the early 50's on back used the vacume off of the
engine
to run the wiper motor. Real early they used a hand crank above the
windshield to operate the wipers.

Heck yeah.
My dad's car's wipers would change speed with engine RPMs. I suppose that
was typical of cars in that era.

Do you remember windshield wipers powered by carb vacuum?

I like the point ignition system. I'm old and can repair them.

Making a new transceiver that uses superhetrodyne now would be like
making
a car that used a point ignition system now.

You will eventually NEED to go to a direct sampling architecture (Orion
4), although you might get away
with one legacy dsp IF rig (Orion 3).
