It may just be noise. I was wondering if anybody else has seen the
same thing.

Because relay contacts are usually rated in VA. "VA" does not specify
AC. VA is the product of volts and amps. But whether the load is AC or
DC isn't the issue; one could decide to define the relay power gain
either way; just say so.
The don't put contact ratings on datasheets? You don't know how to

My friend hadn't heard of it either and was very much taken by surprise.
I believe he'll send that landlard packing if he keeps insisting on it.
If it was me I'd be looking for a building to buy. Just what John did.
No more landlord issues.

That would clogs even the biggest hard drives in a jiffy. 5-10GB per
movie is a lot of gigabytes.
Except that if people really wanted to do that they already can. On
their PC.
But unfortunately when it comes to computing theirs are rather
incompatible products.

He is a fellow (not me, perhaps RG?) who asked you a straight

Feel free to answer Dr Polemic's question any time now...
I will quote it to make it easy for you to answer (or to duck...):
Well? What is your answer?

Last time I used twinlead, except for fiddling around, was on the family
TV antenna installation using an Allied Radio Corodized VHF antenna,
with Beldon Super Permaohm 300 ohm shielded twinlead. Good stuff.

What people have a problem with is that you insist on calling
it "power gain." It's not power gain. It's energy gain.
Average power out over some specified interval doesn't "just
happen" to be equal to energy. It IS energy.
The above is like saying that miles per hour is a unit of
distance. The *mile* (with no mention of time) is a unit of

Maybe... when it's new, of the right type (e.g. tubular), clean, dry,
and carefully installed.
My understanding is that the performance of 300-ohm twinlead
installations tends to deteriorate significantly after a few years
(sunlight and ozone attacks the twinlead, and dirt and pollution
builds up) and during wet weather.

Never heard of such a thing. I see that the Aussies have something
called "lease performance bonds", which is a bit similar. Sounds like
it would be expensive.

The biggest problem with an all-in-one media box is that the "killer feature"
everyone wants is to be able to stick in their DVD (or Bly-Ray disc), hit
"copy to internal storage," wait 5 minutes, and then return the DVD to their
bookshelf and still be able to view the DVD from anywhere in the house at any

Unlikely ... looks nothing like the ones I've used. Both the connections to
the active part appear to be on the same side (left-right as opposed to
front-rear). Also, the facing surface is non-uniform. Since avalanche
photodiodes are usually made by evaporating some conductor onto the wafer
the front surface should be near mirror-like unless it has been damaged
