[BC] Interesting sign-offs

[Ronald J. Dot'o Sr.]

Ya know, I think I was wrong about the squelch noise, kinda.  I now seem to
remember that after the light chain was pulled you'd hear several footsteps
and the door open and close and then you'd hear the squelch noise as they
signed the TX.  And yes, I think it was ch 12 too.

I remember seeing that one, too. Probably KPTV, as they had a legacy
of a hearty sense of humor.

Oh, like Tom Peterson knocking on the "screen" and yelling, "Wake up!" in
the middle of
the night... (His innovative and self-deprecating, mock-obnoxious marketing
is a local
legend; one Halloween The Oregonian printed cut-out face masks, one of which
was
Tom's face.)

Note Mark recalls this as a proposal; I doubt it happened (or for long, if
it did) as dead
carriers are frowned upon by the FCC (as well as the ITU, which is why SW
BCers who
want to stake out their freqs run loops, like RNZ's hysterically pretentious
anno of the
70's), as well as the expense of power consumption.

About ten years ago KOPB would sign off by gently easing back the power over
several
minutes; I think they were nursing a failing TX along until the new one was
funded. (I noted
at the time it was struggling to maintain a quiet black level.) It was a
rare and interesting
thing to see.

See third anecdote on http://www.bvws.org.uk/405alive/info/and_finally.html
claiming ATV engineers once would progressively raise the black level of a
late-night movie so they could
get a better view of what was going on in a flat across the street,
illuminated by only the
television set.
