Why does hubble have a radio antenna?
We're going to assume that you're referring to the "Hubble Space Telescope".
For the answer, you have to go back all the way to 1990, and the last moments before
the Space Shuttle Discovery was launched carrying the Hubble Telescope in its cargo bay.
It was a great day. After almost 20 years in planning, design, and construction, the mighty
scope was ready for orbit, to observe and photograph cosmic phenomena undreamed
of by the millenia of philosophers and scientists whose brilliance had given us virtually
everything we knew about the universe until then. At last, the Hubble was ready to
shuffle off this gaseous coil, to observe and photograph the wonders of this Universe
with an eye unsullied by atmosphere, and a clarity seen by none but their Maker as He
wrote the first paragraphs of Genesis.
The countdown was in its final stages. The Shuttle's crew were belted into their
restraints, the chatter on the Capcom rising in pitch and excitement, the vast
clouds of condensate wafting from the huge external fuel tank in the pre-dawn
twilight as only clouds of condensate can waft, the unsuspecting shorebirds
beginning to stir on their roosts throughout the wetlands of the Cape, rubbing
the sleep out of their beaks unaware of the fire and thunder scheduled to terrify
them in only moments. The countdown, seemingly irresistible and proceeding now
by its own independent will, pulsing toward the single digits, and then . . . . .
A human figure, dwarfed by the towering rocket ship and shadowed in the darkness
on the ground, running, arms waving, screaming, "HOLD THE COUNTDOWN ! STOP
THE LAUNCH ! STOP THE LAUNCH !".
One more millisecond would surely have been too late, but it worked. For whatever
reason, the process was suspended. At the Launch Control consoles, a hundred
red plungers were mashed by an equal number of sweaty palms, a hundred circuits
broke, whereupon condensate ceased its wafting, and a thousand spectator voices
descended as one from among the bulrushes with a unison "AWWWWWWWWWW ...".
The Pad Police quickly had the shadowy figure in custody and whisked him away to
an underground locker room, where he was restrained until officials could be brought in
to interrogate him. He was an engineer, one, in fact, who had worked on the Hubble
project for almost 13 years. Although the fact of his identity as an engineer was quite
enough, not to excuse but to completely explain his apparent total insanity, and more,
he protested that he had an urgent message for them, information pertinent to the launch,
and the more they listened, the more convinced they became that they must listen to this man.
He had been at home this night, sleeping fitfully, when suddenly he sat bolt upright in
his bed as if shocked at every synapse by simultaneous lightning bolts, then leaping
like a madman out of his bed, through his pants and into his shoes, he sprinted to
his car and made straight for the highway toward the Florida coast and the launch
complex, scarce stopping to breathe for the next four hours, until he reached the
Cape with not a moment to spare.
Of all the thousands who had worked overtime, dedicating all that they had to give,
for the success of the Hubble project, this man was the only one to finally realize ...
almost too late ... that they rushed headlong toward a climax which, no matter how
successful, might avail them totally naught. Though the Hubble instrument was poised
to collect images heretofore unseen by any eye, they would stay that way, unless
some means were provided for some eyes to see them ... a provision which, in their
dedication and haste, these absent minded minions had overlooked. There was no
subsystem aboard the payload that was designed to transport the images from the
telescope's orbit to the places where the scientists were. Indeed, there was not even
a mechanism capable of delivering the exposed film to the drugstore.
But now, to avoid allowing the story to grow any longer than it must, we only add
that the collected brain-power available to the project was such that a solution was
proposed and implemented almost immediately. The ham operaters at the launch
complex had a design in moments, the machinists built the mounts only a few moments
later, and the electronics specialists had only to wait until the Coca Beach Radio Shack
opened a few hours later, before they too had their part of the solution implemented.
A radio link was constructed and installed in an unused corner aboard the Hubble,
to beam the stream ... of data, that is ... from the spacecraft to the earthbound
dishes, where it could be read to reconstruct the photos.
The radio antenna you see attached to the side of the Hubble Space Telescope is
the gate through which pictures have poured for over 20 years now, sending for our
wondrous eyes such images as man never before beheld. And as an incidental bonus,
the same team realized, soon after launch, that the same radio link would make it
possible for them to command and control the telescope, directing it to do their bidding,
look where they wanted it to look, go where they wanted it to go, doing the work
that they themselves would do if only they could be there. This lucky accident has
turned out to be the main reason why the Hubble has been so useful, and has
become such a scientific and technical legend in its own time.
Well, yes. They couldn't work if they didn't emit electromagnetic radiation in the form of radio waves.
How many singles were released each week in the 1960s?
That is actually an impossible question to answer. For one thing, you are asking about 10 years worth of singles, at a time when the single was the dominant form of music and top-40 radio ruled. Further complicating the answer is that there were many record labels back then, most of which are now long-defunct. Often, a song would first be released on a small local label and then get picked up and re-released by a bigger label. A good example is the 1963 hit "Louie Louie" by the Kingsmen, which was first released on the local Jerden label and was then picked up for distribution by Wand Records.
Anecdotally, I was a music director at my college station in 1968-1969. Record promoters from all the labels (including RCA Victor, Columbia, Mercury, Capitol, Decca, London, Laurie, Motown, Warner Brothers, Atlantic, Stax/Volt, ABC/Dunhill, etc etc) would come by at least once a week with new releases. There might be as many as 15-20 new records, or as few as 3-5. The amount of new releases really varied, sometimes influenced by whether a name artist had a new record out, sometimes influenced by the holiday season (many new Christmas songs came out in November/December). And I am just telling you about the major label releases-- there were also independent and small local releases as well. Some of these were only known in one small city, while others managed to get some regional appeal. It was a booming time for the record business and there were many stations (both at the college level, and on commercial radio) where airplay was possible.
It sounds like you have the typical Ford radio problem. You're lucky if the behavior isn't completely random.
This guy claims to have the solution for $20.

It requires some soldering, so it's not for the weak at heart. I've yet to try it.
AnswerI had the exact same problem in my 1999 Expedition, The cause was a leak in my windshield. The water dripped down the post and into the fuse box. Check the fuse box to see if water damaged. I had the wind shield replaced along with the fuse box The problem is now corrected.How do you install an aftermarket radio in a 2007 Chevy Tahoe?
Just warning you, its gonna be expensive. You need to carfully pull the trim around the radio off with a panel removal tool. The clips are very tight, be very very careful. Then just unscrew the 7 mill screws holding it in and unplug the harness and antenna.. It may be complicated finding the right parts. Youll need to get a dash kit, harness, and antenna adapter. The dash kit may be hard to find if its the new model of tahoes, usually run around 20 bucks, but this one may be more expensive, not sure about it. The antenna adapter converts the the wierd shaped GM antenna plug to a univeral plug, you will not get radio without it. That will run you about $13. The harness WILL be spendy! Youll most likely need a RDS harness because alot of the electronics are ran through the radio harness. Usually a harness will only cost around 20 bucks, but not in this case. If you dont have onstar it will run you about $120, but if you do it will run you about $150. Good luck!
How can you remove the radio in a VW Bora?
you need special release keys for the head unit to be removed they pus in the slots on the side of the head unit lock in and then you can full it out. check out this site it has pictures and step by step instructions on how to do it. abella.net/vw/changer.shtml hope this helps sharky
How do you contact the Federal Communications Commission?
You may have many different reasons to contact the FCC, but your question doesn't
hint at what they may be.
Fortunately, the FCC's website is very easy to navigate, and zero in on exactly
what part of their business you're interested in. The "related link" down below
will take you there.
A pledge drive is a period of fundraising (that usually lasts for a few days or a week) most often used by public broadcasting stations (such as PBS on television and NPR on radio). Guests, current members, and others usually explain why the station is so important in their lives and then ask others to join or renew memberships by calling in or donating online. There are often incentives for joining or renewing at a certain level/amount--for instance, if you pledge $50, then you will receive a T-shirt. Pledge drives usually occur at least twice a year and sometimes three or four times.
I think I've answered it: It is impossible to create or destroy matter. In a vacuum, electromagentic waves will dissipate, but not completely disappear (they will reduce to an infinetly small amount, but will never reach 0). Particles in space deflect and scatter the waves, and the deflected energy continues to travel, just in a different direction. But no matter what, some of the energy will continue to travel in the original direction. Therefore, remnants of the waves would travel indefinetly in the original direction. If I'm correct, this means that it is possible for radio waves, however small, to travel for 5 billion years. Now the maths: 5 000 000 000 years = 157 680 000 000 000 000 seconds
Speed of light = 299 792 458 metres per second 157 680 000 000 000 000 * 299 792 458 = 47 271 274 777 440 000 000 000 000
Therefore in 5 billion years, the radio waves would travel: 47 271 274 777 440 000 000 000 000 metres
47 271 274 777 440 000 000 000 kilometres
29 373 008 355 817 427 508 480 miles
Calculate the wavelenght of a radio wave whose frequencey is 900 kHZ v 3.00 10 m s?
The length of a radio wave at 900 kHz is 3331/3 meters, or about 1093.6 feet.
How do you remove a jammed CD from car radio in a ford focus?
I removed 2 cds from my 2005. Remove the cover that surrounds the radio. The lighter and htr./ac. will come with it. Just be carefull and use a small screwdriver around the edges to remove it. Romove the 4 bolts that hold radio in place. There are 4 torqs screws that hold the faceplate in place. When that came off mine the 2 cds were sitting in a cavity on top of CD player they should fall out.
Did you buy the battery from new or was it a spare? Clicking sound when trying to turn key in ignition is usually low battery. The radio and lights may still work for a few minutes if there is enough charge left but the engine wont turn over. Turn off all lights, alarm and radio - wait 20minutes and try to turn engine over. Or failing that do what I've said below:
Get someone to jump start your car with jumper leads. Once its running, drive your car around for half hour to one hour to re-charge battery. If fault isn't with battery then it could be alternator or spark plugs. Dodgy spark plugs can cause the car not to start.
AnswerYou probably have a loose connection or corrosion. Clean battery terminals and ends of wires.
Answertry the starter solenoid
AnswerMake sure your battery posts are clean and the cable connectors are clean & tight. If this is not problem don't have another answer.
ANSWER
You might have to replace the ignition swith.
What does am frequency stand for?
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.
The transmit frequency is 140.250 MHz what is the best choice for the receive frequency?
Try 140.250Mhz. There should not be any shift from sent to received.

Where is the fuse for the radio on a 2003 Hyundai Elantra?
I had problem on my 2001 Elantra with power for radio, inside light and trunk light. I found the fuse in the fuse compartment on dashboard on the left side from the steering wheel. To acces it you need to pull out the coin holder. Inside you will see the fuses and diagram with tags. Radio was in the second row on the right if I remember correct. Good luck.
