I have since visited your suggested page to casually view his works.
Interesting set of circuits too (although, some of the phasing systems
have been superceded with shift registers - I used to use
bucket-brigade chips).

I was especially touched to see wide coverage of the R390A. It was
the subject of my first class that I taught in the Navy (along with
the Collins URC-32). Cadillac equipment. I note in his discussion of
stabilizing the BFO, he uses a Rubidium standard for comparison. I
calibrated quite a few of those Rubidium standards too with my Cesium
Beam whenever a Boomer came along side. An URQ-12 would have worked
as easily, but this discussion no doubt exceeds the capacity of your
wallet (the Navy provided such a candy store for my Metrology Lab).

Not just my wallet. This is cool though, I have encountered both bucket
brigade IC's and shift registers. Offtopic question: Did the bucket brigade
lead directly to the switched capacitor filter? I ask because they seem
related, and the BB seems to have become obsolete, but the SCF, anything but.

Same thing if I read you correctly.

Interesting. I guess fabrication accuracy and timing accuracy improvements
led to its sharp cutoff and improved ability. I'm using one in some project I
have on hold, a way to get pitched sounds to control MIDI signals for musical
instrument control. I'll stop that line of thought there though, I'm not
ready to go into that project for a while.

Curious... You might have experiences that give useful insight into something
I'm discussing in another group, some off-the-wall topic I entered into
during a quiet new-year's moment in alt.lasers... I can accept that you might
not want to get into that at all once you see it but if you do I welcome the
input because as I state there, one issue is to find helpful signals rather
than the noise such discussions usually provoke. But it might be a lengthy
misdirection if you're busy so I won't push the point. But I will say now
that my dad was a naval officer when he was younger and he SAW that thing I
described right there with me, and he had no clue either. I just keep
thinking that some people in the navy might be better able to explain it than
most, especially if they have a strong science or engineering background.

Well, I'm not sure what you are trying to bring up here. As far as
I'm concerned, any topic is open for discussion. If others fume and
fulminate about this being an antenna group, I can easily turn the
discussion into one that is antenna specific.

What did your Dad see? (We used to joke that after the Pueblo
incident they put Marine guards outside of the radio shack for
security. If the ship was in danger of being boarded they were to
step into the shack and shoot the operators. Then I went into the
submarine navy, aboard a tender, the USS Holland, AS-32. We had an
escort sub that followed us at sea - to sink us if the Ruskies got too
close. Ah, the humor of those days.)

Antennas? In this case you'd have your work cut out for you. Wasn't just
him who saw it. I saw it first, for an hour and a half, before I decided it
would stick around long enough to justify getting my parents to look at it
too. I'm a bit embarrssed to mention it here other than to point to it there,
but it was two crossed 'beams' in the sky. Trust me, it's hell of a
misdirection if you're not up for it, you'd have to go to alt.lasers and take
a shufti at the posts there.. But I agree, opening it to discussion is good.
I spend about 99.999999% of the time keeping it to myself but I'm getting too
old to want to leave it as unresolved as it is now. If it has to be, ok, but
I ought to try..

Submarines? Those scare me. I never had to go in one, I don't know if
claustrophobia would have beaten me. I have found the sound of water passing
all round me as I waited for sleep in a crew cabin below decks in a ship's
bow to be one of the most comforting sounds I ever knew, so maybe I wouldn't
have.
