Well, maybe.

Velocities approaching c are seen with an air dielectric, or any other
dielectric in which the dielectric constant is close to that of free space.
In coaxial cables, the signal travels exclusively in a non-air dielectric,
and so sees a larger dielectric constant and thus a lower velocity.  In
any reasonable medium, the velocity of propagation depends solely on the
dielectric constant, and is generally given as c/SQRT(k), where k is the
relative permittivity or dielectric constant.  For most common plastic
insulating materials, k is between 1.5 and 5, so we generally see propagation
in the range of 0.5-0.8 c; most common in coax is 0.6-0.7.  Twinlead or
twisted-pair construction has higher velocities, as more of the field travels
in air, for a lower effective dielectric constant.

I attended a session on DCC and MD at the recent AES conference in San
Francisco.

Sony said that the MD decoding algorithm is fixed, but the encoding algorithm
can be changed as improvements are made.  They also said that the algorithm
is currently the same for the professional and home units, but it may not
remain that way.  It wouldn't surprise me to see "improved" recorders hitting
the market in a few years.

DCC, on the other hand, uses a fixed encoding algorithm but allows the
decoder to be changed.  Hence, we might see "improved" players but not
recorders.  I assume this means that the professional and consumer recording
algorithms will always be the same.

The last issue I received was Issue 81, July/August 1992.  Has there been an

I _did_ recently receive the Guide to High End Audio Components... My question

The closest thing I've found in availability is from Cambridge Sound Works.
Their most recent catalog has two MD's in it.  One for $699 (records and plays)
or $499 (Playback only).  But the catalog says "Limited Availability 
December, 1992"  Both models are portables.

All of the well known cleaning devices, Keith Monks, Nitty
Gritty, VPI, et al, use a cleaning solution that has a
compositon of aboaut 75% water, 25% alcohol, and a wetting
agent.

The alcohol is really neccesary to get rid of contaminents that
are untouched by the unversal solvent, water.

Some plasticizers may be removed, but these machines makes sure
that the solutions are on the record for only a short while,
and there really isn't any better way to do it.

To hear a record - even new - before and after use of a
cleaning machine is a revelation.

Too often Discwasher will help embed particulate in the bottom
of the grooves - something only a vacuum devices that uses a
cleaning solution can do.

You may find it hard to believe, but your expectations are based on an
incorrect understanding of the system, as jj very clearly pointed out.
You're coming at this from expectations based on pure digital-to-digital
copying (i.e., "same bits"), and that's NOT what's going on here.  If it 
were, I (and, I'm sure, jj) would be in complete agreement with you.

Turns out I needn't have worried. Instead of the channel I can hit the
"Input" button on the remote and depending on whether I press it once 
or twice it will either tape video from a chosen channel + audio from 
the audio in lines or the audio alone. Took me till 3 in the morning to
discover this undocumented function, but it was worth it.. I wouldn't
have been able to go to sleep otherwise.

Kinda funny having the opening piece on Relativity's "Gathering Pace" 
playing while cowboys ride by...seemed appropriate somehow.

Some questions for you Hi Fi VCR users out there:

1) Is recording in SLP (or whatever its called - 6 hours on a "120" 
   tape) OK for good audio? I'm not out for CD quality here.. just 
   120 minute cassette off-the-air FM quality.

2) How important is auto-tracking? The Samsung doesn't have it; a 
   Sony that cost perhaps another $13 had it, but the Samsung had 
   an "index search" feature so I bought it. I fiddled with the 
   tracking but couldn't discern a difference.

Article-I.D.: ms.1992Nov16.131418.19562
Distribution: na
Organization: University Of Kentucky, Dept. of Math Sciences

I recently bought this nifty old brass doorknob mechanism to replace
the one in our front door.  The "new" one is of the variety with two
push-buttons in the door jamb and a split square hole where the knob
shaft goes through the door; if I push one of the buttons in only one
half of the square hole can rotate.  All of this is separate from the
key lock, which is a normal deadbolt.

The knob shaft is a plain square shaft, so if I engage the button lock
I can't turn the knob at all, short of removing the knob from one side
and pulling the shaft out until it only engages the movable half of the
square hole.  If the door were closed like this one would have a
problem.  Also, I've been unable to adjust the knobs on the shaft to
take up all the slack in the rod; both knobs ride inside collars on the
faceplates which prevent getting at the knob screws unless I leave
about an inch of slack in the rod.  So the shaft slides back and forth
as you use the knob from different sides of the door.

I've concluded that the knob set isn't the original set for
this mechanism.  However, I can't imagine a shaft design that would
allow only opening the door from one side when the lock is engaged
(which I assume is the idea), even if I allow that the slack in the
knob shaft is intentional.

Can someone provide enlightenment?

	This past weekend I attended a coin/money show and did a little
asking around to answer some of the BURNING questions some of you had.

	1) regarding that Dominion of Canada 25cent note from 1900.
		It is apparently common and in top condition
		might be worth $2.50 +

	2) regarding that $100,000,000 (?)(Marks? , obviously not $)
		German inflation note-  These were mostly produced 
		after WWI went Germany went into hyperinflation and
		it cost that much just for a loaf of bread.  The deal
		is, during inflation there is too much money so these
		bills are not rare.  This bill may be worth $5-10+ 
		dollars depending upon condition.  You are most likely
		to get a better price from a WWII collector than from
		a currency dealer.

	3) regarding the WWII ration coupons.. Jack,
		these  are not as rare as you may think. (I still have
		my mother's coupons.)  Your coupons may be worth from
		$5-15 depending upon condition, and commodity.  However,
		you stated that one stamp was torn out so you won't be
		at the top of the range.  You, also, would be more
           	likely to receive a higher price from WWII collectors.
		Especially, it you have a harder to find commodity.

		As an item of interest, I did see an i.d. pass used by
		one of the judges to get into the Nuremburg trials.

		
	Lastly, I want to add a special disclaimer.  I have not seen any
		of these items and am not a currency expert.  If you
                want a real estimate, you should take it to two or three
		dealers for a price.
