I was in 7th grade and already interested in ham radio. I built my
first receiver the next summer and received my Novice license
(KN8MWA) on Nov, 11, 1958. That is 60-years ago! My first reaction
was anger that the Russians beat us. So many Vanguard rocket
failures did that. It took an army rocket (Jupiter-C?) under
the guidance of German WWII rocket scientist to finally launch our
first orbiting satellite. Little did I know that I would be working
for NASA 13 years later.
Of course the Russians also used WWII German rocket scientist.

Awesome!! Thank you, Bruce!!
What kind of devices did they use for transmitting this signal? I wonder
transistors were good enough for this frequency, but.... vacuum tubes??

Lots of interesting stuff in the wikipedia article:
https://en.wikipedia.org/wiki/Sputnik_1#Design but it does not say what the
active device was. A 1 watt transmitter in 1957? Must have been tubes, no?
An interesting thing I did not know: It was filled with nitrogen and used
a fan to cool off the electronics!

Content-Type: text/plain; charset=utf-8
Hello together,
I'm sure you've noticed already that our website??
https://amsat-dl.org?? has changed a lot.
We have now gone one step further and have set up a new online forum at
? https://forum.amsat-dl.org/
Especially with the upcoming launch of P4-A /Es'hail-2 we want to offer
a forum for extensive discussions.
Essentially this is a forum, where everyone can report on experiences
and knowledge from operating satellites and thereby hep other newly
interested radio amateurs to become active and a member of our satellite
community.
Of course all topics around amateur radio satellites and OSCAR's should
be discussed there, appropriate categories and forums were created.? If
necessary this can be extended at any time and on request.
We would be pleased if the new forum is well received and you register
there with your callsign (if available) as your name.
Of course you can also look around as a "guest".
Experienced users can also check in the settings for new entries and
have them delivered by eMail if you wish so.
In this sense, have fun
Peter, DB2OS 1st Chairman
Chris, DL7AG, Webmaster

Hi,
I'm wondering how many radio amateurs could record the received signal
at that time.
Bill VK3JT used BYER Model 66 tape-recorder for this historical sound.

I don't speak or read Russian, but if this is about Sputnik-1, it is clear
that the Tx has 3 tubes, answering one question!

Google ?Sputnik 1 Hackaday? and you will find the Sputnik 1 radio. Yes it
used tubes. PA3CNO did a great job of recreating this piece of history.

So, a quick and dirty translation of the PDF using Google Translate - sorry
I dont have time to do the job properly at the minute!
73, Julian M0NUX
The transmitter of the first satellite, Boris STEPANOV (RU3AX), Moscow
The launch by the Soviet Union of the first in the history of mankind,
the artificial satellite of the Earth on October 4, 1957, was undoubtedly a
world sensation. Newspapers and magazines, radio and television in all
countries of the world reported this event as the main news of those days.
After all, the apparatus created by man for the first time went beyond the
Earth, opening a new era ?
outer space. Actually, no one did
secrets from the fact that soon it will happen. From July 1, 1957 to
December 31, 1958, the International Geophysical Year was to be held. The
United States of America and the Soviet Union announced in advance that it
would launch launches of artificial earth satellites. But at that time, for
most people on our planet, it all sounded a bit abstract, and the media did
not pay much attention to the upcoming launches.
Meanwhile, intensive training was under way in both countries. Many
technical and organizational issues were tackled, among which not in the
last place is reliable and, most importantly, even the non-expert
understandable registration of the satellite's orbit. This was a significant
factor in the competition between the two powers. Signal reception
The satellite ?from space? onboard the satellite transmitter ? what else
could be more convincing for the general public around the world.
At the end of 1956, we made a decision to involve radio amateurs in
observing the signals of the first satellite to register its entry into
orbit and further flight. A subtle hint of this sounded already in the
January 1957 issue of Radio magazine: "It would be good to mobilize radio
amateurs to receive radio signals that will be sent by satellites ...". And
starting from the June issue, we went to publications on possible orbits of
satellites, on observing their signals (with a lot of necessary technical
details), a description of practical designs for conducting and the
technology of these observations. The July issue also published the official
appeal of the USSR Academy of Sciences to radio amateurs. And then there was
a pause - the expectation of the actual launch of the first satellite.
Naturally, professionals also monitored its launch into orbit, but radio
amateurs were among those who were the first to report to Moscow about
receiving satellite signals and, therefore, about its successful entry into
near-earth orbit.
It goes without saying that radio amateurs were not only interested in
technical characteristics of transmitters installed on the first satellite,
but also some details about what they are. However, then this information,
like many other things related to space, was secret. Interest in the onboard
equipment design of the first AES arose again when the 50th anniversary of
its launch was approaching. Descriptions of amateur radio designs of
transmitters on Soviet rod lamps even appeared on the Internet, but now it
can be said with certainty that they had practically nothing in common with
the transmitter of the first satellite: ...
The radio equipment of the first AES was developed at the enterprise, which
today is called Russian Space Systems (formerly NII-885), one of the
founders of the Russian rocket and space industry, created in 1946. The
article ?The Main Designer? by G. Chliyants and the author of this
publication, published in the February 2011 issue of the magazine ?Radio?,
described the main designer of this research institute, Mikhail Sergeevich
Ryazansky, under whose guidance many radio engineering systems for Mi-cal
industry.
Last year, the Russian Space Systems OJSC released a reprint of
a report on the development of an onboard radio station of the first Soviet
artificial satellite of the Earth, which is shown on the cover of this issue
of the magazine. It contains materials on the design and ground testing of
satellite radio equipment. The original report was compiled in 1958.
A noticeable part of it is devoted to the question of choosing the optimal
frequencies for the onboard transmitters of the satellite and their power
based on the data on the Earth's ionosphere at that time. It is interesting
to note that in the form of a popular science article these materials were
published in the magazine "Radio" back in the July 1957 issue!
Without going into details, we note that from the results of this analysis
it followed - with the most adverse assumptions, the frequency of the
transmitter on board should not be lower than 15 MHz. At that time, the
long-range direction finding in the HF in the country worked at frequencies
up to 20 MHz, so this was chosen for the main transmitter. A higher
frequency would be better, but then the available means of direction finding
up to 60 MHz did not provide the necessary accuracy, so a frequency of 40
MHz was chosen for the second transmitter.
Calculations showed that the transmitter signals with an output power of 1 W
can be confidently received on Earth by receivers with a sensitivity of 5
?V. The scheme of the main transmitter ka at a frequency of 20 MHz is shown
in Fig. 1. It was assembled on three 2P19B rod radio tubes. The second
transmitter at a frequency of 40 MHz differs only in the nominal
frequency-determining elements and the matching circuit of the output stage
with the antenna. The frequency of the master oscillator performed on the
VL1 lamp according to the so-called ?Pierce circuit? (the ?anode? function
is performed by the screen grid ), stabilized by a quartz resonator ZQ1. In
both transmitters, the operating frequency of the quartz oscillator was
several kilohertz above 20 MHz. The circuit in the anode circuit of the VL1
is tuned to 20 MHz (in the second transmitter, to 40 MHz). Capacitor C8
symmetrizes this circuit (compensates for the output capacitance of the lamp
of the master oscillator), because th
e output stage of the transmitter is push-pull. It is assembled on lamps
VL2 and VL3 and in general has no features. Note that the filament circuits
of all three lamps are connected in series. Such a solution, if any lamp
failed, would eliminate the energy consumption of this transmitter and
extend the service life of the other. Resistors R4 and R5 are used to
equalize the voltage of the filament on the lamps. There is no pinned data
of induction coils and chokes in the report (this is a report, not a design
documentation!). There is also no data on a trimmer and a dual variable
capacitor, which is set up in the output stage. Constant capacitors, the
ratings of which are not shown in Fig. 1, - tubular KPKS-1 through passage.
The power supply of the onboard radio equipment of the first satellite was
completely autonomous - from silver-zinc batteries. The filament battery
consisted of five elements SCD-70 with a capacity of 140 Ah and provided a
voltage of 7.5 V. The anode battery con
sisted of 86 cells SPD-18 with a capacity of 30 Ah and provided a voltage
of 130 V to supply anode batteries. transmitter chains. It had taps for
powering the screen (90 V) and pentode grids of the output stages (10 V), as
well as the manipulator (20 V). The mass of these batteries was about 50 kg,
i.e. it was a significant part of the mass of the entire satellite. The
batteries were supposed to provide uninterrupted transmitters for 14 days.
Power supplies are not connected to the transmitter housings, which excludes
failure due to accidental short circuits. Since the battery voltage is
higher than the voltage required to supply three lamps, there was a limiting
resistor in its minus circuit (outside the transmitter body). Transmitters
were manipulated by a device on polarized relays by alternately supplying 90
V to screen grids of output cascades. The four antenna beams, which are all
visible in the photographs of the first satellite, are the two beams of the
main transmitter and
two second ones. Figure 2 shows a photograph of a container with
transmitters and a manipulator (it occupies about a fourth of the
container!), And in fig. 3 - the node of one of the transmitters, extracted
from the container. The title page of the report, on which the names of the
main performers of the project are given: M.I. Borisenko, K.I. Greengauz,
V.I. Lappo, A.I. Zinkovsky and the approving signature of M. S. Ryazansky
himself gave us one more surprise. In the 90s, he collaborated with us,
constantly visited the editorial office and published several materials
Abram Isakovich Zinkovsky. We knew him as a competent radio engineer and
accurate author. We knew that before the war I was addicted to short waves
and had the call sign U3DH, that before retirement I worked in a serious
research institute and was somehow connected with space topics. And what was
our surprise when we saw his name on the front page of the report . It turns
out that he was not just ?somehow connected?, b
ut was one of the main performers in creating onboard radio equipment of
the first satellite ? he was responsible for debugging it, design tests and
delivery to the customer. The lead developer of the radio station and the
ground-based device the first satellite was the head of the laboratory,
Vyacheslav Ivanovich Lappo. Theoretical and practical studies of the
propagation of radio waves in the range in which the transmitter worked were
conducted by the head of another laboratory, Konstantin I. Gringauz. And the
project was headed by Mikhail Ivanovich Borisenko. 2 Fig. 3 RADIO No 4, 2013
