Radio

"Radar" comes from RAdio Detection And Ranging. If it didn't use radio it would be called something else.

LIDAR (LIght Detection And Ranging) is laser instead of radio. That uses light.

I don't know if it is the same, but the lights were out in my 97 Chevy truck radio, so I took the radio apart (not a easy feat) and all the seaperate lights for the buttons are soldiered to the circuit board so I am assumeing they are not replaceable, unless I can find a radio store that can put new ones in.

Try this website it is already on the page you need. http://www.corvetteradios.com/corvetteradios_013.htm

it has the bults and a diagram of how to take the radio apart and do the soldering jobs, not the greatest but it is the only one i could find. also i am gonna try this with leds lights from radio shack and see it that works instead of paying 22 dollars for 10 lights. radio shack is like a dollar for 1 maybe two i don't remember

You do your homework, either by yourself or else together with the person

you're going to interview.

-- With all the information about anything and everything and everybody that's

available on the internet, you spend some of your precious time searching this

person and learning something about him. In this day and age, it's totally

irresponsible to show up at the scheduled time and say you don't know anything

about the person, and there's no excuse for it.

-- If you've done any interviewing before this one, then you may have run into

what's called "pre-interview activity". That's where you sit down with your guest ...

or with his agent ... before the interview, and find out what he wants to talk about.

Then you and he agree on what questions you'll ask. On the air, it sounds like

you're running it, but actually he is, and he comes off sounding a lot better.

That's definitely the better way to go if your guest is an entertainer, performer,

actor, singer, comedian, etc.

If instead your guest is a politician/public figure, then maybe you want to challenge

him, trip him up, probe opinions or attitudes of his that haven't been revealed yet.

That's one aspect of what's called "broadcast journalism". But if you're asking this

question, then you're nowhere near that arena. Better to get with your interviewee

before you go on the air with him, and let him set it up. He's been through more

interviews than you have.

Philo Farnsworth (1906-1971), American inventor and pioneer in television technology. Farnsworth developed a television system complete with receiver and camera, but he failed to produce his system commercially.

Philo Taylor Farnsworth was born in Beaver, Utah. His family moved to Rigby, Idaho, when he was 11 years old, where Farnsworth began experimenting with electricity. In 1920, when Farnsworth was 14, he showed his high school chemistry teacher a design he had made for an electronic television. The next year Farnsworth entered Brigham Young University as a special freshman. Farnsworth soon left school and worked at odd jobs until he met a willing investor who lent him money to start building his television.

The television systems being experimented with at that time consisted of a system of spinning disks with holes punched in them and mirrors designed to convert light to electricity. These disks and mirrors could give only poor resolution. Farnsworth called his device an image dissector because it converted individual elements of the image into electricity one at a time. He replaced the spinning disks with cesium, an element that emits electrons when exposed to light. Farnsworth applied for a patent for his image dissector in 1927. The development of the television system was plagued by lack of money and by challenges to Farnsworth's patent from the giant Radio Corporation of America (RCA). He spent his career as head of the Farnsworth Television and Radio Corporation, which he founded in 1929.

In 1934, the British communications company British Gaumont bought a license from Farnsworth to make systems based on his designs. In 1939, the American company RCA did the same. Both companies had been developing television systems of their own and recognized Farnsworth as a competitor. World War II (1939-1945) interrupted the development of television. When television broadcasts became a regular occurrence after the war, Farnsworth was not involved. Instead, he devoted his time to trying to perfect the devices he had designed.

In addition to his television system, Farnsworth invented the first simple electronic microscope and the cold cathode-ray tube, which was used in some early televisions. A cathode-ray tube (CRT) is an electron tube that converts electrical signals into a pattern on a screen and forms the basis of the television receiver. Unlike most cathode-ray tubes, cold cathode-ray tubes produce electrons without being heated.

Farnsworth also worked as a consultant in electronics and later as a researcher in atomic energy. He conducted research on radar and on nuclear energy. Farnsworth held 165 patents, mostly in radio and television.
