Sometimes you can not predict how long a satellite will be used. A
friend of mine worked on a civilian satellite for a defense contractor
and just before the division was sold off, cleaned out any old documents
and files they had on it.

Since the satellite he had worked on was way past its expected life (but
still in use), the contracts had long expired, the work was not
classified and a new improved one was due to be launched in a few days,
he was told to dump it all.

A few days later, the booster exploded on the pad, and the replacement
was destroyed.

The sattelite was kept running for many years, although there were no
documents on what to do or how it was built.

What good is a diagram if the unit is 24,000 miles in the air?

It had better *not* be in the air... ;-)

vacuum with just the tube elements, rather than a typical
evacuated glass (or other material) enclosure...is the

For all sorts of other reasons, standard enclosed tubes are used. Main
reasons are first to contain the electrons so other metalwork doesn't
get involved, and second to maintain the correct physical positioning.
The helix is of very fine tolerance in both pitch and positioning.
Space is certainly hard enough, but the environment around a satellite
is frequently not space, but a diffuse cloud of exhaust gas which
would extinguish a TWT immediately.

Ah. Good point!

Satellites do indeed need to use propellant of some sort
to keep in position; I didn't think of that at all. And it
would seem that even if the ambient vacuum were
hard enough, conventional construction of the TWT
would be needed to keep contaminants out of it during
the satellite assembly process down on Terra firma.
But I must admit, the idea of using ambient vacuum
tickles my fancy a bit. ;-)

I'll prempt the probability that LV will call me a **** and say to
all, respectfully as any gentleman can, that when I am a ****, I know
it, and so LV needn't tell me about it.

Is LV getting WORSE as he's gettin older? wer'e into about 3 posts
from him with the firstie dissing JS for imbecilic reasons, during a
detailed discussion regarding 10,993.5 ways of building a radio and
including side issues of tubes used in satellites. Innocent stuff. And
who'd have guessed so many would have sprung from the woodwork to
discuss tubey radio thingies when most ppl here thought only 3 people
read r.a.t most days?
Anyway, then after such brevity from LV, we get stuff about guns, and
being American. I reckon LV is frightened witless about the world
outside himself.
I invite him to calm down, nobody is about to force him to be un-
american, and probably nobody would find it interesting to do a home
invasion at LV's house. Surely both activities would be boring, no?
Fat lotta good it does to have a shooter under the pillow when ya
snoring ya head off while someone steps out the window with the family
silver. Well, plasma TV set maybe.
But lemme tell ya, one does sure wake up fast when ya reach fo the gun
while half asleep and ya shoot ya ****ing dick off. Dozen madder;
being dickless at 60 yo probably improves a man. But such an event
does has ya thinkin fast about a doctor - **** the TV set, let 'em
have the darn thang.

Funny thing, I never had no need to ever even consider gettin a gun.
Jus' no need. There's no need for a front fence, and no need for any
dog. There used ta be a shiela livin 5 doors away down my street who
used to have a couple of those horrible little yappie terriers. Story
was that some bloke got slightly too amarous with her when she was 17,
about 20 years before and she never got over it. She had one of those
figures and a face that had blokes jus thinkin only one thing, but she
just couldn't handle any man's advance. Anyway, kids round our way
would chuck small rocks at her house windows whenever they walked
past, and this set off the dogs, and that'd set off her neighbours,
and they'd harrange the poor bitch about her 2 noisy dogs and all dogs
and humans involved took an hour to calm down. Comical it was. Anyway,
she musta moved because we don't cop the yap-yap or the argy-bargy
neighbours any more. Lucky it was that nobody had a gun, and that
nobody shot anyone, deliberately, or by mistake.

Such is life in Austrayan suburbs, where of course there are always a
few ppl who have gorn astray, as ppl do, but remarkably, there is very
little blood on the footpaths.

Wow, I lit a loaded fart off here, didn't I?

First, I said use a Hallicrafters band switch and an Eddystone dial
because there's probably a market for those with old Hallicrafterses
with bad bandswitches and with regen builders respectively. The
problem with the Hallicrafters band switch replacement market is that
there are so many DIFFERENT ones, if they were all the same they'd be
reproduced. Remember rotary switches are modular, to a degree, the
company that makes them builds them out of mostly off the shelf parts,
and in fact you CAN get new ones built, but the problem is that they
cost more than the value of most hallicrafters radios, since they have
to put them together as one offs. 500 units takes the price from $400
to $25-50 each. At twenty five bucks a shot you could sell a couple
hundred in six months....IF you had a unit that went into enough
popular radios.

Eddystone dials are a similar thing.

The market has to be a mix of nostalgia and survival mentality. Yes,
a solid state radio can be made EMP proof, or highly resistant, but it
takes some doing.




As far as power in such a situation....In the old days they used car
batteries for heater voltages and a stack of dry cells, a dynamotor or
a vibra-pack for B+..

Look carefully at the old Collins and National sets. They developed
it to something of a fine art.

As an aside, any "survivalist" with half a brain has buried a couple
of solid state complete radios as well as a pile of surplus
semiconductors useful post-Blast in old ammo cans. A stash of common
bipolar and FETs, silicon diodes, common chips for radios and whatnot,
buried under ground could be more valuable than gold and at a hell of
a lot lower current acquisition price today. Some discussion on which
types would be interesting.

I don't consider myself a survivalist but I have a couple of guns and
some ammo buried along with a couple of full jerry cans of 100LL avgas
(it doesn't go bad) and some electronic stuff, plus some garage sale
Craftsman tools, some spools of wire from a motor shop (short ends),
and a couple things I won't mention. Better safe than sorry I figure.

Australia got stupid with its gun laws when they let the 'sheilas'
vote. We got Prohibition under similar circumstances.

Female suffrage was a great idea...NOT!
