signal of TIROS-D during its orbit #1782 was received
on June 12th 1962 by Volkssternwarte
Munich, also called "Satellitenbeobachtungsstation

additional time pulse signal inserted in the recording
which was kindly provided by Tobias Lindemann and Josef

(1963-021B) |
The LOFTI
(Low Frequency Trans Ionospheric Satellite)
American earth magnetosphere satellites were launched
in 1961, 1962 and 1963. LOFTI attempted to determine
whether very low frequency (VLF) energy could penetrate
through the ionosphere and be received by submerged
submarines. The satellites demonstrated that under many
ionospheric conditions VLF signals were extremely attenuated
and could not be detected, making them unreliable for
submarine communication. LOFTI-2A was launched on a
Thor-DM21 Able-Star from Vandenberg AFB together with
Poppy2A (Solrad6), Poppy2B, Poppy2C (Radose) and Surcal3.

TRansit 5B-5 is a radiation
satellite. It studied the magnetic field, celestial
field and collected ultraviolet data. This satellite
was still transmitting end of 2019 and is thus probably
the oldest satellite still transmitting. The sequence

Signals
enclosed were recorded first in AM and then in FM mode.
Recorded on Dec 14th 1973 on
136.650 MHz by Greg Roberts. |
The next
4 recording were made on June 19th
1999 on 136.650 MHz by Greg Roberts. He used a turnstile
antenna at about 10 meters above ground followed by
a low noise pre-amplifier with 20dB gain and about 1
dB noise figure. The first recording used the CW/SSB
mode of the receiver with a bandwidth of 2.4 kHz. |
The second
file was also recorded using the CW/SSB mode with 2.4
kHz bandwidth. Since the satellite signal is quite broad
(>30 kHz) one can easily hear several carriers when
using this mode of reception. |
Here
Greg Roberts used a narrower (0.8 kHz) bandwidth filter
to record the signal in CW/SSB mode. This bandwidth
is recommended for very faint satellites since it cuts
down the background noise. |
This
signal was recorded using the FM detector of the receiver
with a bandwidth of approx. 25 to 30 kHz. Although the
FM modulation of Transit 5B-5 is very low, one can easily
hear the tones. Compare this to the CW/SSB recordings
and it should be very obvious why any serious radio
satellite tracker should have the capability of receiving
CW or SSB modes. FM is not suitable for weak signals.

LES-1
#01002
(1965-008C) |
LES- 1 (Lincoln Experimental
Satellite 1) is a US military communications satellite
launched from Cape Canaveral aboard a Titan 3A rocket.
LES-1 failed to reach Geostationary position when the
booster rockets failed leaving it in HEO. It was abandoned
in 1967. Besides the UHF telemetry transmitter it featured
also an X-band transmitter with 100mW output. More specifically
this was a beacon transmitting at 7740 MHz and a communications
transponder with an uplink at 8350 MHz and a downlink
at 7750 MHz. |

Transmissions
of LES-1 were discovered 47 years after its launch by
Phil Williams in Cornwall/UK on Dec 18th
2012 and verified by other members of the #hearsat group.
The transmissions are not every day and seem to be linked
to extended periods of times when the satellite is in
sunlight. It seems that the transmissions are interrupted
by the availability of extended times when the satellite
is in sunlight. The satellite is evidently tumbling
as can be heard by the wobbling carrier with a time
constant of about 4.5 seconds. The signal is a single
un-modulated carrier on 236.997Mhz. The wobbling carrier
is clearly heard and can be seen also on enclosed spectrum
plot as is the slow normal Doppler shift associated
with its orbit.  Enclosed
recording was made on Dec 19th
2012. AOS was at 12:00h UTC at a frequency of 236.998
Mhz whereas LOS was at 12:30h UTC at a frequency
of 236.992 MHz. Phil used a Create Log Periodic antenna
on an AZ/El mount,  an
LNA580 preamp by RfBay and an AOR AR5000 receiver with an SDR-IQ
connected at the IF output. The spectrum plot was generated
with Spectravue. Recording and spectrum plot kindly
provided by Phil Williams. |
Enclosed
signal of the wobbling carrier of LES-1 was received
and recorded on 236.998 MHz in USB on December 27th
2012 at 06:50 UTC by Matthias DD1US. |
 Enclosed
spectrum plot of carrier of LES-1 shows that there are
2 time periods visible in the waterfall display: the
above mentioned 4 sec interval and a 30 sec interval.
Possibly the satellite is spinning (every 4 sec) and
rolling
end over end (every 30 sec). Received
and recorded on 236.99 MHz on January 4th
2013 at 11:50 UTC by Phil Williams.

 When
LES-1 goes in the Earth shadow the transmiter will stop
operating. When it gets out of the shadow it restarts
transmitting with periodic frequency jumps as can be
seen at the waterfall diagram enclosed. Received and
recorded on 236.99 MHz on January 19th

SECOR
is an acronym for Sequential Correlation of Range and
is basically an electronic distance measuring system
in which four ground stations sequentially interrogate
a satellite-borne transponder. It was used by the US
Army Map service from 1964 onwards. Early satellites
transmitted on two carrier frequencies, namely 224.5
MHz and 449 MHz. Recorded first in AM and then in FM
on 136.840 MHz on Dec 14th

The US
satellite Solrad 7B was also called GRAB (Galactic Radiation
Experimental Background ) and was officially instrumented
to detect the solar X-ray emission.  The
first GRAB satellite was launched in 1960. However its
receivers were used to catalogue the waveforms and pulse
repetition frequencies of Soviet air defense radars.
The basic concept of operation is shown in the diagram

TIROS-10
OT 1
#01430
(1965-051A) |
Tiros-10 (Television
and InfraRed Observation Satellite) is
a sun-synchronous meteorological spacecraft designed
to
develop improved capabilities for obtaining and using
TV
cloud-cover pictures from satellites and operated as
an
interim operational satellite. The spin-stabilized spacecraft
is in the form of an 18-sided right prism, 107 cm
across opposite corners and 56 cm high, with a reinforced
baseplate carrying most of the subsystems and a cover
assembly (hat). Electrial power is supplied to the spacecraft
by approximately 9000 1- by 2-cm silicon solar cells
that were mounted on the cover assembly and by 21 nickel-cadmium
batteries. A single monopole antenna for reception
of ground commands extends from the top of the
cover assembly. A pair of crossed-dipole telemetry antennas
(235 MHz) project down and diagonally out from the
baseplate.
TIROS-10
features an advanced vidicon camera system (AVCS).
AVCS (television) transmission was at 235 MHz with
2 W output power.
TIROS-10
transmits tracking signals with 50 mW on 136.230
(increased over lifetime to 136.235 MHz) and 136.920
MHz.

Pegasus 3
Saturn
SA-10
#01467
(1965-060A) |
In its
stored position with panels folded inside the Apollo
service module Pegasus 3 was 5.3 m high, 2.1 m wide,
and only 28 cm deep. The spacecraft was equipped with
appendages like wings which extended to form a huge
plane 29.3 m long and 4.3 m wide. Pegasus 3 transmitted
on 136.410 MHz (data) and 136.890 MHz (telemetry and
tracking beacon) and sounded like the previous 2 Pegasus
satellites. This signal is probably the beacon on 136.89
MHz and was recorded in the time between March 1964
and February 1965 by Greg Roberts in Durban. |

Alouette 1 was a Canadian
small ionospheric observatory instrumented with a sweep
frequency ionospheric sounder, a VLF receiver, an energetic
particle experiment, a cosmic noise experiment and a
electrostatic probe. The spacecraft used two long dipole
antennas (73 m and 22.8 m long). Alouette-2 had a tracking
beacons transmitting with 50 mWatts on 136.980 MHz and
two telemetry transmitter on 136.080 MHz (2 Watts) and
136.590 MHz (0.25 Watts).Routine operations were terminated
in July 1975. The spacecraft was successfully reactivated
on November 28th and 29th
1975 in order to obtain data on its 10th
anniversary. |

In August
2013, 48 years after its launch, signals from Alouette-2
were jointly rediscovered by Raydel Abreu Espinet CM2ESP
in Cuba and Mike Kenny in Australia. All 3 transmitters
could be detected. The detected signals were:
136.590
MHz : a variable strength stable carrier with weak intermittent
sidebands at approx. +/- 3.5, 5.0 and 13.5 kHz
136.080
MHz : a variable strength unstable carrier 4 to 5 kHz
below nominal frequency and weaker intermittent unstable
sidebands at +/- 20 to 23 kHz from the carrier
136.980
MHz : a strong stable carrier only
Signals were received in SSB on October
3rd 2013 at 23:10 UTC by Raydel
CM2ESP in Havanna/Cuba. Raydel used a horizontal Moxon
antenna fixed pointed to Zenith and a RTL-SDR Dongle
with a 35dB preamplifier. Recordings kindly provided
