Buy a Real Sputnik Satellite! Let's Put Sputnik Back in Orbit!
Here's the description:
---------------
Laboratory Test Model of "Sputnik 1 EMC/EMI", 1957
1:1 scale test model of the satellite "Sputnik-1", serial no. "0K6-1/004/1957", with built-in transmitter (including modern 12-volt power supply), polished stainless-steel sphere, consisting of two threaded hemispheres of approx. 23 in. diameter with two pairs of antennae of 95 in. and 105 in. at an angle of 35 degrees to the axis, on stand with O-ring, stand approx. 59 in. high, stand and model together approx. 79 in. high, accompanied by a Tesla Maj 620A radio receiver, manufactured in Prague c. 1956, restored working condition, including replacement of the silver-zinc battery with a modern alternative and a new metal casing for the electronic transmitter. Note: Built at the Experimental Design Bureau-1 (OK?-1/OKB-1) factory, also known as S.P. Korolev Rocket and Space Corporation Energia, Koroljow, Soviet Union, in 1957, shortly before the launch of Sputnik-1. - An impressive artefact from the dawn of the space age, of which few models are known. - Provenance: From the collection of Dr. Frank Malina, USA/CSSR.
Start Price: EUR 85.000
Here's my suggestion: Musk or Bezos or Branson should buy this thing, fix it up a bit, and put it back in orbit. So we can listen to it again. I know a version of this was done back in 1997. But I think we should do it again, this time with the actual test model.
Here are the earlier SolderSmoke blog posts about Sputnik and Sputnik-related projects:

Steve Silverman sent the auction posting to me. Thanks Steve.
It just so happens that earlier in the week I was out at the Air and Space Museum facility near Dulles Airport, where I saw this flight backup of the Vanguard satellite:

Sputnik 40 Launched from MIR in 1997
I'm new to SolderSmoke, and have made it up to episode 135. around episode 130 you entered a "space" phase that I enjoyed. With Sputnik being mentioned, I thought I would send you a recording of Sputnik 40 that I made on November 23, 1997. I used a home made turnstile antenna and an HT.
73,
Jeff Tucker
W9TLT
Sputnik 40 was launched, along with a backup spacecraft and the X-Mir inspection satellite, aboard Progress M-36 at 15:08 UTC on 5 October 1997. A Soyuz-U carrier rocket placed the spacecraft into orbit, flying from 1/5 at the Baikonur Cosmodrome in Kazakhstan: the same launch pad used by Sputnik 1. Progress M-36 docked to Mir on 8 October, and the satellites were transferred to the space station. At 04:05 UTC on 3 November, during an extra-vehicular activity, Sputnik 40 was deployed by cosmonauts Anatoly Solovyev and Pavel Vinogradov.
On 4 November, the day after it was deployed, Sputnik 40 was in a low Earth orbit with a perigee of 376 kilometres (234 mi), an apogee of 382 kilometres (237 mi), an inclination of 51.6 degrees, and a period of 92.13 minutes.The satellite was given the International Designator 1997-058C, and was catalogued by the United States Space Command as 24958. It ceased operations on 29 December 1997 when its batteries expired, and subsequently decayed from orbit on 21 May 1998. The backup satellite remained aboard Mir, and was destroyed when Mir was deorbited on 23 March 2001.

Sputnik Party 2012 Soapbox
3 October from AA1TJ:
Here's an admittedly late reminder that the Sputnik Party begins
tomorrow (4 October). I've been preoccupied with non-hobby concerns in
recent months but I did manage to throw something together for the
event.
My transmitter follows the lines of the 10mW, battery-powered, RF
beacon that was carried into orbit in 1958 by "Vanguard 1." You may
recall this is the one Premier Nikita Khrushchev characterized as "the
grapefruit satellite."
My present build uses essentially the same circuitry and componentry
as did an earlier, 20m version; details of which can be found at
http://aa1tj.blogspot.com/2012/06/vanguard-1-satellite-transmitter.html
The 15m version drives a 44m end-fed wire with 30milliWatts.
The receiver that I built for the event is essentially a "Q-multiplier
-> detector" type regenerative job. However, the Q-multiplication is
accomplished by a parametric amplification using a quartz-crystal
controlled pump. I thought it would be historically appropriate given
that parametric amplifiers were all the rage in the late 1950's.
I put together the keying and R/T changeover circuitry this morning.
When it appeared that "all systems were go" I began sending CQs on
21.060MHz. The band, or at least that portion of the band (the
receiver only tunes from 21.060 to 21.064MHz), seemed rather quiet,
but my 6th call netted a "dit dit dah dah dit dit." Resending my call,
I was very pleased to hear HB9DCL come back to me from just outside of
Zurich. The reports were 579/339. Frank was running 5W to a log
periodic antenna. I sure hope this is a sign of things to come!
I hope to be at the key by 1300Z tomorrow. Although my little
"grapefruit" only puts out 30mW, folks running "Sputniks" made from
ex-Soviet subminiature "rod tubes" should be at least two S-units
stronger. A number of European stations will be operating this year
and at least one station that I know of will be QRV from Japan. Just
listen for the beeps and give them a call!
Thank you,
Mike, AA1TJ
.......................
letter to some of the guys
Dear Friends
I won't forget this morning's QSO with ON6WJ anytime soon! As he
beeped/called CQ I could hear him riding on waves of QSB. I kept
hoping he would end on the top of the wave. It happened one time and
Jos sent "AA1TJ?" but by the time I re-sent my call we were back in
the trough of the wave. He started calling again and once again I
crossed my fingers. Finally it happened, he ended on top of a
particularly strong peak...and sure enough, he copied my callsign. It
took more effort to exchange the reports but we eventually did it! He
confirmed my 559 and I did the same for my 339 report. It must be true
that anything worthwhile doesn't come easy, because the more difficult
the QSO the more I seem to enjoy it! I copied Jos' info: "SPUTNIK PWR
700mW = ANT 3EL YAGI" perfectly on my tiny receiver. Just as amazing,
he copied my 30mW transmitter made from one PNP Germanium transistor
dating from September of 1959. Needless to say, I'm a happy camper
today. Merci Beaucoup, Jos.
Just above my operating frequency I heard PA0PJE sending "CQ Sputnik."
You had a beautiful signal here, PJ! It was easily S6 on the peaks. My
transmitter frequency trimmer adjustment is buried in a rat's nest of
wires which I didn't dare stick my hand in so early in the day.
However, if I hear you again I will definitely risk it.
Thanks Carlo/IZ4KBS and congratulations on your Russian QSO. Any
contact all with this simple stuff is reason for a celebration!
...and now back to the Hobbit Hole for another dose of QRPp.
73/72,
Mike, AA1TJ

Can we put a Sputnik signal back in space for $300?
http://hackaday.com/2011/10/11/send-a-satellite-into-space-for-300/
We just make the antenna a bit longer and put it on 20 MHz. Or for a shorter antenna, 40 MHz.
Bert and the fellows out at UVA are going to take care of the whole SETI thing (Jerry, NR5A, was in the lead on this -- he started the SolderSmoke SETI-AT-HOME group). But we'll need some additional volunteers to cover the Low Earth Orbit portion of the SolderSmoke Space Program. And of course we have to come up with the 300 bucks.

Comet Hits Sun, SFI up, Report from San Vito
The SOHO spacecraft caught some great images of a comet crashing into the sun. The YouTube clip above is from July. Here is NASA video of one that took place just last week:
http://www.nasa.gov/mission_pages/sunearth/news/comet-cme.html
Coincidentally I'm sure, the solar flux has increased significantly and the upper HF bands are working again. My 17 meter rigs still need final amps -- I am ordering parts for Farhan's JBOT circuit. (I plan to build three or four.) But because I had the 2B on 15 meters for the Sputnik event (still no Sputniks heard here) I noticed that DX was coming on that band. Using my HT-37 and a 40 meter dipole I easily worked several Europeans on 15 meter SSB. Especially nice was a long rag chew (using my rusty Italian) with Gianfranco, IZ4NPE, in beautiful Ferrara, Italy (a bicycle city).
Somehow tying this all together, I got an e-mail from Walter in San Vito, Puglia (the heel on Italy's boot). Walter has one of those "dream jobs" for a radio amateur: He tracks sunspots!

Listening for Sputniks, Watching a Satellite
I felt like a junior high school kid yesterday, rushing into the shack, firing up the old rigs, anxious to tune in some special stations. It was Sputnik Anniversary Day! 15 meters was still in pretty good shape at 2315 UTC. On the trusty Drake 2-B I could hear W1AW's code practice session a bit above the Sputnik frequency of 21.060 MHz. All of a sudden WA5TCZ was booming in, calling CQ Sputnik! OM Darron later e-mailed and let me know that he wasn't running a replica rig -- like me, he was looking for them.
This morning, inspired by all this space activity, I pulled out my newly cleaned and collimated telescope and took a tour of the skies of Northern Virginia. Jupiter is very bright in the East (I could see the Galilean moons in my finder scope!) Mars is in the West, but is too far away for any detail to be seen in my 'scope -- it is just a little red disk. I had to go out into the street to position the 'scope for the great nebula in Orion. At 1023UTC the International Space Station flew over -- I watched it disappear into the sunrise. A good morning indeed.
I have a suggestion: Can the Sputnik event be extended through the weekend to give more people the chance to tune in these magnificent rigs?

Sputnik Rigs Cross the Pond, Cambridge to Cambridge
http://g3xbm-qrp.blogspot.com/2011/09/sputnik-across-atlantic-today.html
We clearly see the spirit of the International Brotherhood of Electronic Wizards in Roger's comment: "Nice to think that valves used in missiles aimed at each other in the Cold War end in bringing friendship and joy. CW is a wonderful mode if you want simple equipment capable of DX." Indeed. Well done!

Getting Ready to Listen for Sputniks
But I have come up with a way to participate in this historic event even without a homebrew replica transmitter: I will be listening for the Sputnik transmitters, and I will be doing so with a receiver of that era, a receiver that could have been used by some earnest teenager eagerly tuning for the beeps of the overhead RED MENACE. Like the intrepid young man in the picture. What a great shot! Wow, that's Roy Welch W0SL, then W5SLL! When I got into satellites in the Dominican Republic in 1994, the first tracking program that we used was Orbits II... by Roy Welch. We loved that software. From the AMSAT page: "Roy and his two-year-old daughter would put the radio speaker in a window and then go outside and listen to the strong signals while they watched the third stage booster tumbling end over end like a bright pulsating star as it passed over in the evening sky."
I will be using a Hammarlund. Moore's "Communication Receivers" says my HQ-100 was made between 1956 and 1960. PERFECT! (Mine was probably in the Dominican Republic on October 4, 1957.)
By the way, I got into the old Electric Radio magazines again, reading some more of Lew McCoy's wonderful reminiscences. He reports that during the Sputnik period he -- and apparently others -- were asked by their Uncle Sam to use their skills to monitor Soviet space activities.
Let the beeping begin! (Sputnik signals recorded by Roy Welch:
