[R-390] R-648

[Bill Hawkins]

Never used one, but saw one at a hamfest after I had repaired
and used an R-390.

While the R-390 is a mechanical marvel, it is relatively easy
to work on, like a 1938 Ford engine.

The R-648 is an aircraft radio, where weight and size must be
minimized and there is no 110 V, 60 cycle power. Think of a
carefully crafted Oriental puzzle or today's Ford engine.

I left the R-648 behind because I've got enough puzzles in my
life. I buy VT equipment because I can fix it, but that didn't
seem to apply to the R-648. I don't work with old wristwatches,
either.
