Rapp's remarkable contributions
spanned a period of more than three decades (1941-1962, 1972),
I remember an article, probably April '55, where
Rapp described a method of "amplitude discrimination".
If one used such a method, one could simply tune
in the weak signal by tuning out the strong ones.
Such amplitude discrimination required "back to
back limiters". When I asked my Elmer, W5OLV, how
to build a "back to back limiter", he couldn't stop
laughing.
And I remember one solution of his to TVI was to "find seats for the
standing waves...."
Those were the days. It would be the ultimate joke on us if someone
really was going to publish the "collected works".
