Hi Sebastian, W4AS
Electrical causes:
Before to open the rotor check if the starting capacitor C35 for the 24 volt
AC motor is OK
Looking at the schematic diagram of your G-5400B rotor you will see
that the starting unpolarized electrolitic capacitor C35, 100 uF is located
inside the elevation rotor.
While running UP the rotor the voltage measured between the common
of the motor numbar E6 and numbar E5 must be about 24 Volt AC and if the
voltage measured between E4 and E5 is about 24 volt AC it indicates that
the electrolitic capacitor C35 is not short circuited and both windings
of the motor are OK
While running DOWN the rotor the voltage measured between the common
of the motor numbar E6 and numbar E4 must be about 24 Volt AC and if the
voltage measured between E4 and E5 is about 24 volt AC it indicates that
the AC electrolitic capacitor C35 is not short circuited and both windings
of the motor are OK
If the motor don't runs in any of both direction UP and DOWN disconnect
the wires of the control box from terminals E4-E5-E6 of the rotor and
measure the ohmic resistance of the motor windings.
If C35 is not short circuited you must measure the following resistances
for the rotor windings.
Between terminals E4 and E6: 5 ohm
Between terminals E5 and E6: 5 ohm
Between terminals E4 and E5: 10 ohm
If the motor still don't run check C35 100 uF and measure it's capacity
in uF because even if the voltage across it as measured between terminals
E4 and E5 is 24 volt AC it can be an open capacitor.
If the above C35 must be replaced and you decide to open the rotor remember
that the manufacturer has used liquid "loctite" into the treads of the
screws.
To remove each screw do not attempt to use a percussion screwdriver
but it is necessary to heat the head of the screw using a small gas flame
after that a small wise grip size 5WR immediately applied is enough.
Mechanical causes:
In general the elevation rotor stuck mechanically when the ball bearing
holders are defective because one or more teeth of the ball separators
are broken.
When the ball separators are broken then the boom shaft tube falls
down a litte bit so that the assembly tube gear do not engage anymore
into the teeth of the final pinion of the gear box
Each bearing has 20 balls and since the ball separators are difficult to
find and they are a source of problems I have removed that separators
addeding I don't remember if 2 or 3 more same size balls to compensate
for the room of the above ball separators.
In any case as soon the rotator is open you will be in condition to find the
problem by your self.
Reassembling the rotator set the 500 ohm potentiometer with the wiper
at 250 ohm each side and position the mark over the cast of the boom shaft
tube for 90 degrees elevation.
Have fun and 73" de

Hi Guys,
My two cents worth. It looks like Sebastian has made all of the
checks. I assume the rotor will not move in either direction. It's
possible that something had fallen into the gear train, jamming the
works but it does sound more like a bad motor. Have you measured all of
the voltages and especially the resistance values on the motor leads as
shown in the owner's manual? If the resistances all look good and the
supply voltages are good then I would check the resistance from each
motor lead to the metal case to see if there is a short circuit to the
rotor housing. I'm not sure but in some countries RFI hash protection
has been added to the rotor circuitry consisting of small RF chokes and
capacitors mounted inside the rotor case. For example, my Emoto rotors
don't have it but the versions sold in some European countries do have
it. You might check to see if there is a similar thing in your rotor
and that there are no failures there. I doubt that this is the problem
however. Good luck.

During the 20:45 UTC pass over Delft I uplinked a pulsed carrier to
test the transponder functionality.
The 10 pulses with various length were successfully received by our
omnidirectional SDR station within the passband. The used power was
75W with 14dBd antenna gain. (about 1.8kW ERP)
The transponder is working just fine at that moment.
However, We are still interested in all of your uplink experiences and
signal reports.

Nobody's complained about it but is anybody actually interested in these
Chinese mission keps I'm posting twice a day?
I would imagine that you'll only heat transmissions from the ship whilst it's
within range of China although it's satellite might be audible.
It was stated ( www.bbc.co.uk/news ) that the satellite would orbit it's
mothership to take pictures of it.

Greetings,
I finally?decided to try L/U on AO-51 using?my IC-910H, SATPC32, 70-cm arrow
on a camera tripod, and a 10-elem. "cheap yagi" for the 1.267-GHz uplink.?
Very good signals for all on the downlink most of the pass, however my uplink
on 1.267-GHz is heavily affected by trees, the fact I operate from inside my
home from the 2nd floor,?and I was arm-stronging the cheap yagi whilst
twisting for polarization!.? Great to hear?Angelo, Carmen, Clare, and Mike.?
Thanks for calling me back in the group.??A?very cool mode that works very
well.

ARISS Confirms Amateur Radio Hardware Deliveries
AMSAT News Service Bulletin 272.02
>From AMSAT HQ SILVER SPRING, MD.
September 28, 2008
To All RADIO AMATEURS
BID: $ANS-272.02
The ARISS team received confirmation from Sergey, RV3DR, that the
recent Progress flight delivered the flight backup D-700, a David
Clark Headset for the Ericsson system, and an additional VOX box
and cables to support the computer-operated SSTV system. The D700
may be installed as early as late this week, depending on crew
availability. The flight backup will not provide a significant
change in ARISS operations, making it easier for the crew to change
program modes.
Richard Garriott plans to take a Kenwood VC-H1 SSTV communicator
with him on-board the Soyuz for his flight and leave it aboard the
ISS for future ARISS use. The VC-H1 has completed all hardware
certification on the US and Russian sides. The final test, an EMI
radiated emissions test, was performed last week and the test data
was delivered to Sergey Samburov, RV3DR in Russia this week. The
VC-H1 provides a very simple interface for ISS crew members and does
not require the use of a computer. Computer usage has been a real
challenge for ARISS, so the VC-H1 represents a lesson learned to
improve ARISS operations.

September 28, 2008
To All RADIO AMATEURS
BID: $ANS-272.03
Early during Richard Garriott's flight, he expects to setup the
VC-H1 SSTV system and autonomously transmit a new Earth image
every 3 minutes. He hopes to have this system on a great deal
of his flight. We encourage the ham community to bring SSTV
equipment into schools and download these images in real-time.
The ARISS team also plans to display images from hams around the
world on a special on a web/blog site. A beta site has been de-
veloped and will be rolled out to the ham community in the near
future.
To successfully implement the on-line SSTV picture site and support
it 24/7 during Richard's flight, we will need some savvy individuals
that can sort through the many SSTV photos that ARISS will receive
and keep the SSTV site up to date in near real time. Some computer
skills will be required. We are looking for global support from a
few individuals in each international region to make this happen.
That way we will not be asking individuals to volunteer all-night
to realize this project. If you are interested in helping on this,
please e-mail Frank Bauer, KA3HDO directly via ka3hdo(AT)amsat.org.

along with AMSAT-UK has the great pleasure of announcing our joint
application to launch the proposed "EuroDAST" micro-satellite onboard
the Arianespace VEGA launcher, with its VERTA-1 flight opportunity."
Florio continues, "Although it be launched with a European Launcher and
is based on an AMSAT-Italia mission concept, the development of such
micro-satellite is open to worldwide contributions in hardware and soft-
ware." Any individuals or groups of interested amateurs, universities,
research centers having space based hardware or software concepts are

It's been overcast here for the last 48 hours. I've been hoping to go
