Re:What about intra-solar system signal repeaters?
on
Goodbye, Galileo
·
· Score: 1
I have always wondered about NASA being able to create a set of intra-solar system repeaters that they would send out into space, and have them simply repeat signals back from our spacecrafts. That means we could still pick up signals from such spacecrafts as Voyager and Pioneer spacecrafts by having the repeaters send them back to Earth.
I'm guessing it's cheaper and less risky to build super sensitive reciever dish antennas here on earth. Remeber, radio waves travel at the speed of light, and that's a finite speed, so no matter how many repeaters you sent up, they still have to make the journey back, and that takes time.
And the longer any craft will go out into space, the longer it will take for that signal to come back.
"Good performance in a small size" is relative, of course -- I like the quiet little EPIA system in front of me pretty well;)
Most of the new Pentium M laptops are mostly passive cooled. I can barely hear the fan on my friends laptop when it does kick in.
Why doesn't someone make a Mini-ITX case for this board, that comes with a laptop style cooler and has a small slit on the side of the case as an exhaust, just like a laptops?
If the orbiter were left to circle Jupiter after running out of propellant (barring an intervention, this would likely happen within a year), it might eventually crash into Europa, one of Jupiter's large moons. In 1996, Galileo conducted the first of eight close flybys of Europa, producing breathtaking pictures of its surface, which suggested that the moon has an immense ocean hidden beneath its frozen crust. These images have led to vociferous scientific debate about the prospects for life there; as a result, nasa officials decided that it was necessary to avoid the possibility of seeding Europa with alien life-forms. And so the craft has been programmed to commit suicide, guaranteeing a fiery, spectacular end to one of the most ambitious, tortured, and revelatory missions in the history of space exploration.
- Why was morse code originally required for amatuer radio operators?
- How often is morse code used today?
- What advantages does morse code have, vs other forms of radio communication?
Most of the early gear was built by operators. There was no commercially avaible gear. You built everything by scratch, and the first radios were CW, then voice.
Despite what most non hams would love to tell you, CW is widley used on the HF bands. Why? It is a highly efficient way of operating.
When band conditions are not optimal for voice or othe rmodes, CW usually gets through, and usually with less power. Morse is universal, so talking to that Japanese will not be a problem. When I first became licensed as a No Code Novice (teenager at the time) I too thought CW was moronic and for old times, and thought I would never use it. Then I started to read more about things like QRP (5 watts or less) and home brew gear and my interest in CW grew.
Go visit sites like Small Wonder Labs or Nor Cal QRP kits and take a look at some of these high quality CW battery operated kits. Were talking a handfull of parts, battery operated, less than a couple of watts and you could literally work the world all within a few Khz of band space. Some of these kit's are availble for under 40 bucks, and can be built in one night with some hand tools and a low wattage soldering iron. Now go read the reviews of some of these "kits" compared to high priced, bells and whistles laden, rush to market, poor quality control, consumer rigs.
Some of the younger people (ages 9-18) trying to get into the hobby today just don't have thousands to spend on a new all-in-one 100 watt radio. Some of these people are also turned off to the fact that they'll become appliance operators. They could just surf the net at 1Mb instead.
So in respects to CW, some folks don't look at the BIG picture when it come to this antiquated mode.
Some of our worst nightmares came true on Sept. 11, and it was a disaster on a grand scale. But what if there was a disaster on a national or even planetary scale? Isn't bulletproof, battery operated worldwide communications with a simple wire antenna sound like a great idea?
I don't have any objections to having CW dropped as a requirment, but I do think that if it does happen, people will eventually want the CW portions of the HF band turned over to other modes, which I object to.
Reminds me of a scene from Fast Times at Ridgemont high, where Jeff Spicoli has a pizza pie delivered to class. When the professor fumes at why he's disrupting his class time, Spicolli retorts "If, like, I'm here, and like, you're here, does'nt that make that our time?"
With SCO's asshat logic, McBide must be and alumin of that same school or a long lost relative of Spicolli.
P.S. The professor agrees with his obtuse student, and proceeds to hand a out a piece of the pie to all the students.;)

Your bride wants you to spend a lot of money committing to her so she can trust you: she wants to know that you'll be around to help raise the kid before she accepts your seed.
No wonder half of all marriages fail within the first year.Some people think that in order to prove you love & trust I halve to fork out thousands of dollars? I don't know which is worse, you having the gall to make such a statement (AC no less) or the 4 knuckle heads that modded you up.
Yes, right after they tell you how much better records sound than CDs, and that aliens are stealing their newspaper.
Vinyl does sound better than a CD. You can't can't make sweeping generalizations without having first the oppurtunity to listen to both formats. Truncated 16 bit digital, even when played with the best of CD players and/or DAC's (Mark Levinson. Classe Audio, etc) is audibly inferior to the vinyl disc. I'm sorry, but even the hardiest proponents of CD upsampling will tell you that, once you throw those bit's away, there gone forever.
Don't get me wrong, I thought vinyl addicts were delusional once myself. I love the convenience of CD: portability, instand skip to track, really deep bass.
But after auditioning a decent analog setup (decent meaning $500 table/arm/cart combo and a $199 solid state phono preamp) it was almost a religious experience. Even my girlfriend, who isn't an audiophile by any defenition of the word, noticed how much more easy going the music was, compared to the same albums on CD.
The fact is, people just like the sound of a tube more, because of it's distortion.
You probably right, but then again you could say humans are analog in nature and distorted, and that's ok. Just realize that most young people today have never heard a decent analog setup with some tube amps. Woudn't it be interesting if (and, I admit, this is a big if) the reason people are buying less music, or spend less time listening to music for pure pleasure (as oppesed to having it as background music while using a PC) is because digitized truncated music doesn't connect with the human soul the way an analog signal does?
That sound, in fact, could be reproduced with a good DSP.
I'm sorry, but I highly doubt that. Analog and digital will always be just that.
I wish that anybody who has even the slightest interest in analog music reproduction to go find a good hi-fi audio dealer and ask them a an audtiom of even a modest tuntable/phono preamp combo. Most dealers (the ones in NYC do anyways) have vinyl discs on hand. But your better off going in with an album that you really familiar with, and album you would take to a desert island if you could only bring one with. Go listen to it on vinyl and see what happens. You ain't go nothing to lose.
Personally, the amount of time invested in vinyl (keeping discs clean, storing them properly, having to lift teh stylus and placing on the disc -MANUAL LABOR!!SHOCK HORROR!) is well worth the benefits of listening to pure analog music.

I was a little surprised nobody mentioned this story that was posted recently here.
If this man and his product really pan out, we could see some eally exciting advances in the semiconductor industry. But there could be a billion dollar enterprise that might think otherewise.
A quote from said artice:
But De Beers wasn't backing down. Throughout 2000, the cartel accelerated its Gem Defensive Programme, sending out its testing machines - dubbed DiamondSure and DiamondView - to the largest international gem labs. Traditionally, these labs analyzed and certified color, clarity, and size. Now they were being asked to distinguish between man-made and mined. The DiamondSure shines light through a stone and analyzes its refractory characteristics. If the gem comes up suspicious, it must be tested with the DiamondView, which uses ultraviolet light to reveal the crystal's internal structure. "Ideally the trade would like to have a simple instrument that could positively identify a diamond as natural or synthetic," De Beers scientists wrote in 1996, when the company unveiled plans to develop authentication devices. "Unfortunately, our research has led us to conclude that it is not feasible at this time to produce such an ideal instrument, inasmuch as synthetic diamonds are still diamonds physically and chemically."

Three questions for all you hams:
