Very interesting, Richard, of all the years I've been on this NG you are
the first RCA person I've met on the NG. What years were you with RCA?

1965-1980. My position certainly was not as exalted as that of
Epstein/Lewis/Siukola/Maxwell/et al, but I was fortunate enough to work with
Siukola and Ben-Dov of Gibbsboro in developing and proving RCA's RF Pulse
test equipment system used to evaluate and optimize broadcast TV antenna
systems. This test system may be thought of as a "narrow-band TDR," in that
it duplicates the spectrum of the standard TV signal, rather than using a
bandwidth of maybe 100X that of the TV channel. Excess test bandwidth gives
high pulse returns outside the TV channel -- which are valid, but
unimportant to the performance of the antenna system.
