Where does the magnet in a speaker get its power from? Why doesn't it
run out?

My DX pal, Gary Deacon has just caught KSL Salt Lake City on 1160 khz using
his ancient (unmodified) rusted and salt encrusted Yaesu FRG-7 and his
ALA1530 which sits hanging unmounted on his cupboard door. Salt Lake City is
9,700 miles from his suburban home in Fishoek, a small coastal resort near
the main city of Cape Town. The catches he gets from home attests to the
remarkable "sea gain" experienced on the MW band when you DX from the beach
(or near it).

He did get a better catch than that at our September equinox DXpedition when
he caught CASH in Tecate Mexico, right next door to San Diego CA. That was
at the Seefontein DX cottage right on the beach of the Atlantic ocean, also
using his Frog but then with a 1,300 foot beverage antenna over the shoulder
to New York.

Motto of the story is that you don't have to have the world's latest whizz
bang radio to get those amazing DX catches, but as Conrad Hilton said, it's
all about position, position position!

More info on Gary's activities at Fishoek and our Seefontein DX site can be
found athttp://www.dxing.info

John,

Yes, know what you mean. I've just spent two weeks in Fiji. I took a Sony
ICF-SW55 portable and 20 feet of wire which I put up inside a bungalow. The
little bungalow was about 10 metres from the water's edge.

I've done this before several times. It is incredible what you can hear.
Mainly, because of what you CAN'T hear - namely all the electrical static
and noise pollution of living in a city! It's like an astronomer escaping to
the desert with a telescope - seems like there's many more stars than usual.

On a clear day, you can hear for ever! And sometimes the signals you get are
very weak. But also very audible because there is simply NO noise.

Under conditions like these, a simple portable radio and piece of wire will
out-perform many a city-based high-end receiver setup.

Well said Mark - you fella's have really got to get those radio's down to
the seaside.
The results will exceed all your expectations!

There is only one suitable antenna for this extremely wide frequency spectrum being the Windom. This antenna is effectively a 'serial quarter wavelength'. For MW it would be best to use two such antennas to try have at least some element close to quarter wavelength at any one time. One feature of a quarter wavelength antenna is that it also operates at odd multiples of frequency i.e. that which works at 550kHz will also work at 1650kHz, so only one piece of wire will cover both ends of the band. I admire your thoughts and your way of expressing and putting it in front of readers is really something that I have seen after a long time.Thank you for the site.

Those push button car radios of years and years ago. They had a habit of drifting off station. Every once in a while they needed to be re set. I have about half a dozen of those old push button car radios.

I don't remember them as particularly drifty, and I grew up in the
Arizona Desert. They are usually Permeability Tuned (variable inductors)
which are much more stable than most variable capacitors in tuning duty.
Plus the IFs in those days were wide open and stations were allowed to
broadcast in HiFi.

Ferrite cores age, I am told. That could be a reason for a
slow drift (on the order or decades, perhaps).
