Legend has it Ragnarok will begin when Fenrir the wolf breaks free from his imprisonment. This sets off a chain reaction of events where Jormungand the Midgard snake rises from the sea and a wolf eats the sun. This will culminate in a titanic battle among the gods, men and all the races of the nine worlds.

General Radio Discussion / a woman’s suggestion!!
« on: February 13, 2014, 0232 UTC »
It all started with a GREAT woman’s suggestion!!

HISTORY OF
THE CAR RADIO
Seems like cars have always had radios,
But they didn’t.

Here’s the story:

One evening, in 1929,
Two young men named
William Lear and Elmer Wavering
Drove their girlfriends to a lookout point high above the
Mississippi River town of Quincy, Illinois, to watch the sunset.

It was a romantic night to be sure,
But one of the women
observed that
It would be even nicer if they
could listen to music in the car.
Lear and Wavering liked the idea. Both men had tinkered with radios (Lear served as a radio operator in
The U.S. Navy during World War I)
And it wasn’t long before they were
Taking apart a home radio and
Trying to get it to work in a car.

But it wasn’t easy: automobiles have ignition switches, generators, spark plugs, and other electrical
Equipment that generate noisy static interference, making it nearly impossible to listen to the radio when the engine was running.

One by one, Lear and Wavering identified and eliminated each source of electrical interference. When they finally got their radio to work, they took it to a radio convention
In Chicago ..

There they met Paul Galvin,
owner of
Galvin Manufacturing Corporation.
He made a product called a
“battery eliminator”, a device that allowed battery-powered radios to
Run on household AC current.

But as more homes were wired for electricity, more radio manufacturers made
AC-powered radios.

Galvin needed a new product to manufacture. When he met Lear and Wavering at the
radio convention,
He found it. He believed that
Mass-produced, affordable car
Radios had the
potential to become
A huge business.

Lear and Wavering set up shop inGalvin’s factory, and when they perfected their first radio, they installed it in his Studebaker.

Then Galvin went to a local banker
To apply for a loan. Thinking it
Might sweeten the deal,
He had his men install a radio in
The banker’s Packard.

Good idea, but it didn’t work –
Half an hour after the installation,
The banker’s Packard caught on fire. (They didn’t get the loan.)

Galvin didn’t give up.
He drove his Studebaker nearly
800 miles to Atlantic City to show
Off the radio at the
1930 Radio Manufacturers
Association convention.

Too broke to afford a booth, he parked the car outside the convention hall and cranked up
the radio so that
Passing conventioneers
could hear it.
That idea worked — He got enough orders to put the radio into production.


WHAT’S IN A NAME
That first production model was
Called the 5T71.

Galvin decided he needed to come up with something a little catchier.
In those days many companies in the phonograph and radio businesses used the suffix “ola” for their names –
Radiola, Columbiola, and Victrola
Were three of the biggest.

Galvin decided to do the same thing, and since his radio was intended for use in a motor vehicle, he decided to call it the Motorola.

But even with the name change,
The radio still had problems:
When Motorola went on sale in 1930, it cost about $110 uninstalled, at a time when you could buy a brand-new car for $650, and the country was sliding into the Great Depression.
(By that measure, a radio for a new car would cost about $3,000 today.)

In 1930, it took two men
several days
To put in a car radio –
The dashboard had to be taken
Apart so that the receiver and a
Single speaker could be installed,
And the ceiling had to be cut open
To install the antenna.

These early radios ran on their own batteries, not on the car battery,
So holes had to be cut into the floorboard to accommodate them.

The installation manual had eight complete diagrams and 28 pages of instructions. Selling
complicated car
Radios that cost 20 percent of the
Price of a brand-new car wouldn’t
Have been easy in the best of
Times, let alone during the Great Depression –

Galvin lost money in 1930 and struggled for a couple of years after that. But things picked up in 1933 when Ford began offering Motorola’s pre-installed
at the factory.

In 1934 they got another
boost when
Galvin struck a deal with
B.F. Goodrich tire company
To sell and install them in its chain
Of tire stores.

By then the price of the radio, with installation included, had dropped to $55. The Motorola car radio
was off and running.
(The name of the company would be officially changed from
Galvin Manufacturing to
“Motorola” in 1947.)

In the meantime, Galvin continued to develop new uses for car radios.
In 1936, the same year that it introduced push-button tuning,
it also introduced the Motorola Police Cruiser, a standard car radio that was factory preset to a single frequency to pick up police broadcasts.

In 1940 he developed the first
handheld two-way radio
– The Handy-Talkie –
for the U. S. Army.

A lot of the communications
technologies that we take for granted today were born in Motorola labs in the years that followed World War II.

In 1947 they came out with the first television for under $200.

In 1956 the company introduced the world’s first pager; in 1969 came the radio and television equipment that was used to televise Neil Armstrong’s first steps on the Moon.

In 1973 it invented the world’s first handheld cellular phone.

Today Motorola is one of the largest cell phone manufacturers in the world.

And it all started with the car radio.

WHATEVER HAPPENED TO
the two men who installed the first radio in Paul Galvin’s car?

Elmer Wavering and William Lear, ended up taking very different
paths in life.

Wavering stayed with Motorola.
In the 1950′s he helped change the automobile experience again when
he developed the first automotive
alternator, replacing inefficient and unreliable generators. The invention lead to such luxuries as power windows, power seats, and, eventually,
air-conditioning.

Lear also continued inventing.
He holds more than 150 patents. Remember eight-track tape players? Lear invented that.

But what he’s really famous for are
his contributions to the field of aviation. He invented radio direction finders for planes, aided in the invention of the autopilot,
designed the first fully automatic
aircraft landing system,
and in 1963 introduced his
most famous invention of all,
the Lear Jet,
the world’s first mass-produced, affordable business jet.
(Not bad for a guy who dropped out of school after the eighth grade.)

Sometimes it is fun to find out how
some of the
many things that we take for granted
actually came into being!

AND

It all started with a woman’s suggestion!!
