US Space Fence Shut Down

It is reported on SatWatch that the 216 MHz US Space Fence, used to
detect orbital objects, was turned off on September 1, 2013 at 0000
UT.

The Air Force Space Surveillance System (AFSSS), known as the Space
Fence, is a U.S. government multistatic radar system built to detect
orbital objects passing over the United States. There are three
transmitter sites operating on 216.983, 216.97 and 216.99 MHz and six
receiving stations.

According to Wiki the system is understood to be capable of
detecting a 10 cm object at an altitude of 30,000 km and makes 5
million satellite observations each month.

Early in August Space News reported that: Gen. William Shelton,
commander of Air Force Space Command, “has directed that the Air
Force Space Surveillance System be closed and all sites vacated”
effective Oct. 1, the memo said.

It seems appear the closure may have occurred earlier than initially
reported.

The reason for the shutdown has been reported as being because
Federal Government expenditure is exceeding budget resulting in
automatic budget cuts known as sequestration, however, a Space Review
article suggests another reason
http://www.thespacereview.com/article/2357/1

Air Force Space Command (AFSPC) officials say they have devised
modified operating modes for the Perimeter Acquisition Radar
Characterization System at Cavalier Air Force Station, N.D., and for
the space surveillance radar at Eglin Air Force Base, Fla., which
allows the discontinuation of AFSSS operations while still
maintaining solid space situational awareness.

Say HI to Juno

NASA’s Juno mission is inviting amateur radio operators around the
world to transmit a coordinated message on the 28 MHz band to the
Juno spacecraft.

NASA’s Juno spacecraft will fly past Earth on October 9, 2013 to
receive a gravity assist from our planet, putting it on course for
Jupiter.

To celebrate this event, the Juno mission is inviting amateur radio
operators around the world to say “HI” to Juno in a coordinated Morse
Code message. Juno’s radio and plasma wave experiment, called Waves,
should be able to detect the message if enough people participate.

Juno will have a better chance of detecting the signal from many
operators if the signal is spread out across the spectrum. The Juno
Waves instrument is a broadband receiver, and the detector being used
for this event has a band width of 1 MHz. It is better for detection
of the signal to have a broadband signal coming in.

For this experiment, the Juno team would like to ask those
participating to spread out in frequency across the 10 meter band.
They have supplied a table of suggested frequencies between 28 and 29
MHz, based on the last letter of your call. When the HFR receiver is
tuned to 28MHz, the center frequency is 28.5 MHz. A 50 kHz high pass
filter limits low frequencies hitting the detector, so the frequency
table excludes 28.5 MHz ±50 kHz. The natural signals the team expect
to measure at Jupiter will consist of a large number of discrete
tones, so spreading the signals out in this manner is a good
approximation to the signals Juno is expected to detect. But at
Jupiter, they don’t expect to be able to decode CW in the telemetry!

The 28 MHz band was chosen for this experiment for several reasons.
The Waves instrument is sensitive to radio signals in all amateur
bands below 40 MHz, but experience with the University of Iowa
instruments on the Galileo and Cassini earth flybys shows significant
shielding by the ionosphere at lower frequencies. As sad as it
sounds, the team hope for lousy band conditions on October 9, so an
appreciable fraction of the radiated energy escapes the ionosphere
into space, and is not refracted back down to the ground somewhere
else on the planet.

Juno’s antenna consists of a pair of tapered 2.8 meter long titanium
tubes, deployed from the bottom deck of the spacecraft under the +X
solar array and magnetometer boom. A high impedance radiation
resistant preamp sits at the base of the antenna and buffers the
signals from 50 Hz to 45 MHz. The elements are deployed with an
opening angle of about 120 degrees. Ten meters is above the resonant
frequency of the antenna and NEC analysis indicates a lobe generally
along the spin axis of the spacecraft. This will be good for
detection on the inbound part of closest approach to Earth.

The Waves instrument uses four receivers to cover the frequency
range of 50 Hz to 41 MHz. Signals up to 3 MHz are bandpass filtered,
sampled by A/D converters and FFT processed into spectra using a
custom FFT processor developed by The University of Iowa under a
grant from the Iowa Space Grant Consortium.

The Juno team point out that All transmissions must follow local and
national regulations.

Please join in, and help spread the word to fellow amateur radio
enthusiasts!

Space Station Slow Scan TV Active

Dmitry Pashkov UB4UAD has posted two images that he received on
145.800 MHz FM from the International Space Station (ISS) on
Wednesday, September 4, 2013.

All you need to do to receive the SSTV pictures from the space
station is to  connected the audio output of a scanner or amateur rig
via a simple interface to the soundcard on a Windows PC or an Apple
iOS device, and tune in to 145.800 MHz FM. You can even receive
pictures by holding an iPhone next to the radio’s loudspeaker.

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld
with a 1/4 wave antenna will be enough to receive it. The FM
transmission uses 5 kHz deviation which is standard in much of the
world.

Many FM rigs in the UK can be switched been wide and narrow
deviation FM filters so select the wider deviation. Handhelds all
seem to have a single wide filter fitted as standard.
On Windows PC’s the free application MMSSTV can be used to decode
the signal, on Apple iOS devices you can use the SSTV app. The ISS
Fan Club website will show you when the space station is in range.

For more on Slow Scan Television SSTV, see this article SSTV – The
Basics.

2013 AMSAT Symposium Tours Announced

AMSAT has arranged for two special tours as part of this year's
Symposium.

Battleship USS Texas BB-35

On Sunday there will be a tour of the Battleship Texas BB-35, the
only surviving US Navy warship that served in both World Wars.  It is
currently opened to the public while undergoing extensive restoration
to ready her for the 100th anniversary of her commissioning in 2014.
A special tour has been arranged for AMSAT Symposium participants.
Transportation will depart the Marriott at 1030, and the formal tour
will be completed at 1400. Transportation will be available directly
to Houston Hobby airport from the ship.  There will be an optional
lunch at a popular local restaurant followed by a return to the
Marriott at 1600.  Cost per person, not including the optional lunch,
will be $20.

Johnson Space Center and W5RRR JSC ARC

On Monday there will be a tour of the NASA Johnson Space Center.
The tour will include the Sonny Carter Neutral Buoyancy Lab and the
Building 9 Training facility containing high fidelity full scale
mockups of the International Space Station modules as well as the
Soyuz spacecraft.  The ISS tour will include special emphasis on the
amateur radio stations on the ISS. The tour will also include the
Building 30 historic mission control room as well as the current
International Space Station control room, and s a visit to the JSC
ARC station W5RRR. Transportation will depart the Marriott at 0800.
On the return trip transportation will stop at Houston Hobby airport
at 1415 before returning to the hotel. Cost per person will be $30.

CEPT Considers Use of 5830-5850 MHz Satellite Band

The CEPT SE24 Short Range Devices meeting M72 took place in Vienna
on August 26-27, 2013.

The meeting discussed the use of the frequency bands 5350-5470 MHz
and 5725-5925 MHz ('WAS/RLAN extension bands') for wireless access
systems including radio local area networks (WAS/RLANs).

Any use of Amateur Satellite Service downlink band of 5830-5850 MHz
for this purpose would inevitably raise the noise floor making the
weak satellite signals even harder to receive.

+ Move away from the center of the passband

Drew KO4MA suggests moving away from the center of the passband
while working the linear birds. Previous to SatPC32 being the
ubiquitous way to operate the transponders, people tended to spread
out much more on the linear sats. CW was generally in the lower third
to maybe middle, and voice was often spread out over much more of the
passband. Now...I love Sat PC32, and I like full Doppler tuning, but
just because the program defaults to the middle of the passband
doesn't mean everyone should operate within 10 KHz of there.

See http://tinyurl.com/ANS-251-LinearOps

Spread out and use the VFO! There's no reason to pile up like
sardines in the middle. Maybe even (GASP) edit the doppler.sqf file
to put you elsewhere in the passband to fine tune things at the start
of the pass? Got a schedule, or operating from a rare grid? Let
everyone know where to look (i.e. 25 khz up from the middle) and save
yourself and others some QRM?

Erich, DK1TB, offers this tip, if you want SatPC32 to start off the
center of the passband of an SSB/CW satellite do the following: Run
the program choose  that satellite. Tune the radio to the start
frequency you want - say 8 kHz above the center of the passband. Then
click menu CAT > Change/Store Data File > RX/TX Freq. Data. From the
next program start the program will start at the new downlink and
uplink frequencies.
