I saw this on Kickstarter. Looks like a great concept but the team did not
reach they funding goals by August 5th.
Curious to see if they can get other funding from somewhere else to test
this concept.

Nick,
Finally dug through my Yaesu receipts to get the AZ pot info from this past
April. At that time, the part number was S8101678, "Pot. 500 Ohm(new).
Price, including shipping, was $20.51. This pot doesn't have the wire from
the wiper.
Also, while I had the azimuth rotor disassembled, I installed a thermal
switch mounted against the motor windings. The "Thermal Circuit Protector,
75C" is All Electronics part number THSW-75 and was $1.00 (less shipping).
When I next have to open the elevation rotor I'll install one there, too.

HamTV Bulletin 2 - September 10, 2013
Ham Video - EST and Simulations
Ham Video Commissioning preparation is
progressing. An EST (Experiment Sequence Test)
has been performed 28-29 August and Simulations
tests were done 5-6 September 2013.
The EST consisted of a series of tests, mainly of
the ground segment. For the Commissioning, the
VLBI (Very Long Baseline Interferometry) station
of the Italian Space Agency (ASI), located near
Matera, southern Italy, will be used for
receiving the DATV signals from the ISS. For the
EST, the IK1SLD ground station, situated at
Casale Monferrato, northern Italy was used.
IK1SLD is one of the ARISS telebridge stations,
fully equiped for VHF and UHF. It was recently
upgraded for S-band with a 1.2m dish, feed,
downconverter and precision tracking motors.
For the EST, a very low power transmitter,
installed in the shack, generated signals on the
Ham Video frequencies, transmitting a DATV
recording at 1.3 and 2.0 MS/s and FEC ?. The DATV
signal was received and decoded by the IK1SLD
station and webstreamed to the BATC server. See
British Amateur Television Club http://batc.tv/ Members Streams.
B.USOC (Belgian User Support and Operations
Center ? ESA) conducted operations. B.USOC and
EAC (European Astronaut Center ? Cologne,
Germany) specialists operated from Livorno at
Kayser Itallia's laboratory, where a Ham Video
unit, the so-called EBB (Elegant BreadBox), is
operational. Parties involved were interconnected
per teleconference. At Casale Monferrato, Claudio
Ariotti IK1SLD and Piero Tognolatti I0KPT
produced, received and webstreamed the signals in
the different configurations as requested by
B.USOC. ESA and ARISS observers participated to
the EST teleconference. After debriefing, the EST was declared successful.
Simulations were done differently. B.USOC
supervised from their offices in Brussels and
ARISS responsibles Piero Tognolatti I0KPT and
Jean Pierre Courjaud F6DZP operated from home.
The simulations were done in the Columbus mockup
at EAC, where a non operational Ham Video model
is installed. This box is used for astronaut
training on Ham Video. A KuPS power supply was
also used, as well as a camera similar to the one
onboard Columbus in space. Ham Video
transmissions were simulated in the different
configurations (frequencies and symbol rates). A
view of operations in the Columbus mockup was
webstreamed to the participants. ARISS operators
simulated reception as if thery were at the
Matera ground station, taking into account
expected timing between AOS and LOS. They
signaled AOS and requested ?crew? at EAC to
transmit in different configurations, according a
pre-determined scenario. At LOS, the test stopped and results were commented.
Four ?passes? were simulated this way, using both
ARISS antennas. An important goal of the
simulations was to check the efficiency of
communications between ground and ?crew?.
Commands were initiated by ARISS operators
(supposedly from Matera), received at B.USOC,
relayed to the Columbus Control Center at
Oberpfaffenhofen near Munich and uplinked to
?crew? by EUROCOM. The European ISS Control
Center is called Col-CC and its spacecraft
communicator's call sign is EUROCOM. The
Simulations were conducted successfully and
lessons were learned for gaining time on
transmitting commands. This is important
considering the limited 8 minutes contact time during real Commissioning.
ARISS proposed to use our VHF uplink capabilities
to ?crew? for the Commissioning. This was not
acceptable with regard to ESA's commissioning protocol.
Presently, ISS pass predictions for Matera are
computed for several weeks starting mid October,
The Matera VLBI activities are to be taken into
account for determining usable passes. Four
passes will be needed to fullfil the Commissioning requirements.
Ham Video Commissioning activities will be
decided by ESA and NASA ISS Operations. Hopefully
the Commissioning will be planned during
Expedition 37. We will keep you informed.

Gaston Bertels ? ON4WF
ARISS-Europe chairman

Thanks Gaston,
I am glad that testing is progressing and succesful. For the actual
commisioning and ISS testing it would be very helpful if signals from the
ISS are not just limted to the European window but test signals are also
transmitted across NA. We have a number of folks getting stations ready in
the US and Canada. I hope that this option can be discussed with ESA, NASA
ISS operation.
