Commands for WREN SSTV Released

It is believed that the SSTV PocketQube WREN is currently in a mode where it
beacons on 437.405 MHz for 1.6 seconds then listens for 6 minutes on that
frequency for any commands. If none are received it goes to sleep for 2 minutes
before transmitting the beacon again.

The WREN team have released the following information on their Facebook page to
enable radio amateurs to activate the WREN SSTV transmitter.


Commands to WREN are sent by toggling the carrier [of a FM transmitter]:
Carrier on/off: 1=long, 0=short, leave a noticeable silence between the bits.

• Activate/HK: 110011
• wait until answer [should be within 2 seconds]
• Camera ON: 11111
• wait until answer
• Snapshot & Thumbnail receive: 110
• decoder should display thumbnail picture 12*14 pixel can repeat this command
   until something useable appears
• SSTV send: 110100
• martin-1 SSTV picture comes
 in 320×240 pixels color

Wren should answer to the commands within two seconds.
Wait always at least two seconds after having received data before sending to

Send the Activate/HK command first, else WREN won´t react to other commands.
When camera is OFF, a snapshot or SSTV command will send WREN into sleep mode.
WREN´s housekeeping data will show the status of camera power (ON or OFF).

The Telemetry Decoder and an Audio File of the beacon are available at

FUNcube - AO73 Data Warehouse

Since the acquisition of the first signal by ZS1LS on Thursday 21st Nov. there
has been a steady
stream of data flowing in.

A few warehouse statistics as at 12:00 UTC, Nov. 28th 2013:

- over 12MB of unique data uploaded and stored
- 424 user registrations since 2013-11-17
- 319 users have have uploading data
- 41388 Real-time entries
- 11754 Whole Orbit Data entries
- 77940 High Resolution entries

Graphs of WOD and HighRes data are now on the web site:


Thanks go to all the individuals and groups who are helping to characterise the
performance of the satellite by uploading the data. Please keep it coming and
the word about how to get involved.

South Africa ZACube-1 Now Named TshepisoSat

The South African Radio League posted this news in their SARL News
Sunday November 24 Bulletins:

On Thursday 21 November  2013 the French South African Institute of
Technology (F'SATI), at the Cape Peninsula University of Technology,
made history by being the first in South Africa, and indeed the first
in Africa, to launch a locally built nano satellite into orbit from a
site in Russia.

Deon Coetzee, ZR1DE, who represented SA AMSAT at a ceremony held in
the auditorium at the university campus reports that  Vice Chancellor,
Prof. Vuyisa Mazwi-Tonga, paid tribute to all at the university who
made this achievement possible, and said she was immensely proud of
being part of it all.

Original known as ZACube-1, the satellite has been named TshepisoSat,
after a competition held for Grade 9 learners. Tshepiso is the seSotho
word meaning promise.

The launch was the culmination of five years' work after the first
proposal to build a small satellite as part of the engineering
curriculum was put forward by Professor Robert van Zyl in February
2008. Co-operation of the French Government made possible the forming
of  F'SATI  and the French Ambassador in South Africa, Elizabeth
Barbier, during a video address, promised continued support by France
for the programme.

ZACUBE-1 was one of fourteen cubesats aboard the thirty metre tall,
three stage rocket. All the cubesats were successfully released at a
height of 600 km above the Earth. TshepisoSat will circle the Earth up
to fifteen times per day in a polar orbit.

"At 11h13 the first signals from ZACUBE-1 were received amongst loud
cheers", Deon said. According to Francois Visser, ZS1CED, who was the
principal engineer and student mentor, the satellite was functioning
well. The satellite also includes a small camera which will be used to
monitor the releases of the 20 metre beacon antenna. The beacon will
operate on 14 099 kHz  and will be used to characterise the Superdarn
antennas at the Antarctic which are used to study the ionosphere. A
UHF beacon operates on 437,345 MHz. Follow  progress at

AMSAT in the Press

+ The Fall 2013 issue of CQ VHF published an article by George Carr,
WA5KBH. George wrote about his experiences as "Being the QSL Manager
for CO6CBF." The article begins on page 30.

+ The Fall 2013 issue of CQ VHF also includes the regular Satellites
column by Keith Pugh, W5IU. Keith writes about amateur radio's 30th
anniversary in manned space flight, the upcoming HAMTV experiment on
the ISS, and FUNcube. Keith's column begins on page 60.

You are cordially invited to participate in Straight Key Night on OSCAR 2014,
sponsored by AMSAT for all radio amateurs throughout the world.

Operate CW through any amateur satellite from 
0001 through 2400 UTC on 1 January
2014, using a manual, non-electronic key.  Note that bugs are now allowed, as
they are in similar ARRL and SKCC events.

There is no need to send in a log, but please nominate someone you worked for
Best Fist.  Your nominee need not have the best 
fist of those you heard, just of
those you worked.  Send your nomination to w2rs at amsat.org..  A list of those
nominated will be published in early February.

This year’s event is being held in memory of Robert Morris (1902-1997), W2LV.
Bob’s amateur and professional career in radio literally spanned the era from
spark to satellite.  One of the first to work across the Atlantic in 1923, he
also received Satellite DXCC No. 2 in 1979.  Bob was featured in the PBS-TV
documentary, “Empire of the Air.”
