I was a bit surprised to see that day length has changed
for GPS purposes at least

http://www.livescience.com/forcesofn...rth_shape.html
The general shape of the Earth is slightly oblate - that is, it is not a
perfect sphere but is slightly squished down, making it about 26 miles wider
at the equator than between the poles. This shape, however, is not rigid,
with climate being a major distorting force.
But the magnitude nine earthquake last month almost certainly altered the
shape as well. Recent calculations have estimated that this catastrophic
land displacement caused a small reduction in the bulge, making the planet
more round.
"The waistline was reduced by not quite a millimeter because of the
earthquake," said Benjamin Fong Chao from NASA's Goddard Space Flight
Center.
This slimming down sped up the rotation of the Earth, much like when a
spinning ice skater pulls in her arms to increase her speed. The length of
the day correspondingly decreased by 2.68 millionths of a second.

It used to be slower than the speed of sound back in the 1970s. You'd
turn on the TV and hear the programme immediately, but it'd take five
minutes before you saw the picture.

'g' (acceleration under gravity), the constant, is constant (having been

'g' is not 'G'.

One is the gravitational constant that gives the scale of the
proportionality between F, and the various masses and the distances
that are giving rise to a gravitational force between two bodies.

The other is the acceleration due to gravity, which is a measurment of
the strength of the gravitational field that has resulted from an
interaction such as the one described above.

Then there's 'apparent' g, which is what you are thinking about, which
is the percieved g on the Earth's surface, which is not a constant at
all places on the Earth's surface, due to fluctuations in rock
density, differing heights above sea level, and nearness to the
equator, as the centrifugal force introduced by the earth's spin
modulates the effect of the gravitational field somewhat.

I am still struggling to understand which 'G' of 'g' it was that Cynic
is talking about.

Almost certainly. We live in a densely populated country with good
radio and TV coverage. I imagine there are more people suffering
problems with urban ghosting than there are with remote weak signals.
Input stages also have AGC and very good sensitivity these days. In
such cases, a simple attenuator is more use than a bigger antenna. A
gadget like this (which I assume to have some level of band-pass
filtering) probably works very well for those people suffering from
out-of-band interference, induced pickup in long antenna leads, and
much ghosting.

And of course, if your existing antenna is already working well,
you're unlikely to shell out on any new gadget. So even if this thing
is useless for nearly everyone, for probably two thirds of those
people who have a problem, it's quite possibly appropriate - contrary
as its technical capabilities might suggest.

Years ago I worked briefly for the radio interference investigation
branch of BT. In one small area (underneath a local radio transmitter)
a standard technique was _unplugging_ the aerial altogether. There was
just too much of it - no sensible radio could cope. Signal strength
was such that I really did hear Radio Merseyside on Granny's fillings.

Okay - to be precise c is a constant related to the age of the universe. As
you say it is slowing down very gradually now, though in the first few
milliseconds it plummeted down the curve.

Don't believe you. To get a good clean signal, the best way is with a
decent roof top aerial and a good downlead. If this results in too much
signal, an attenuator is pennies.
The problem with any set top aerial at UHF is reflections from people
moving about in the room etc. Hence get the aerial above any such
interference. This also applies to decent MF reception - get the aerial
above the interference fields and use a decent screened feeder.

And of course, if your existing antenna is already working well,
you're unlikely to shell out on any new gadget. So even if this thing
is useless for nearly everyone, for probably two thirds of those
people who have a problem, it's quite possibly appropriate - contrary

a standard technique was _unplugging_ the aerial altogether. There was
just too much of it - no sensible radio could cope. Signal strength

It was usually due to 'poor' receiver design - it was picking up the
strong signals elsewhere than the actual aerial input. A decent receiver
will filter out all the crap at every stage - as will a simple amplifier.
But this costs money.

Years ago, I spent some time sorting out a very expensive TV of a pal who
lived close to Crystal Palace, and who had a near unwatchable picture. It
took quite some time, but the components cost pennies.
