No CW beacon was heard. FM downlink was acquired at 0312 UTC with at least
S7 and no fading but some noise.
MET = 49 minutes
IHU temp = +39 degrees C (not sure about final integer due to noise)
Control panel temp = +28 degrees C
Battery voltage = 35.70 Volts
Battery current = -12 mA
Transmission stopped at 0313 and resumed at 0315 with ID and greeting.

Hello
I need some ideas in trouble shooting? my LVB tracker problem.? The computer
quit talking to the tracker.? The doppler part is ok, to the 910. when I try
to "park" the antenna...nothing.? My LVB uses a serial port on the
computer.? Ideas please.

Hi Bob'
1. Has it worked before?
2. What tracking software do you use?
3. Is the serial port part of the computer, or is it a USB to serial
converter,
if it is a converter, what model it is?

I believe that there is at least one frame of emergency power telemetry
in this attached file, the others I believe indicated high power. I
believe that the voltage indicated was about 35.6 while in emergency
power mode. I could only hear the satellite for about 3 minutes. It
was only 10? elevation at the apex from my QTH in New Mexico. My
antenna system is a small horizonially polarized 7 element cheap yagi
and mast mounted pre-amp.
I hope this information helps indicate the health of the satellite. It
almost seems like a software bug and not a battery problem. The
satellite seems to switch to low power unnecessarily when the voltage
the telemetry indicated is greater than 35.

Mike, KI7AB

Hi to all, after about 2 weeks from deployment , Edusat satellite appears
not to have transmit any single radio signal from space on the spectrum of
UHF and S-Band,
No news or report from University of Rome , who coordinate in part the
project http://www.gaussteam.com/ , only the notice of succesful launch..
but not other
Mission Failed??

Bob,
Use the process of elimination to isolate the problematic component:
Try to install a serial port monitor on your system:
http://technet.microsoft.com/en-us/sysinternals/bb896644
This should give you an idea if the data is sent to the serial port from
SatPc32. If you see the data sent, I would try to change the serial port
cable if you can, or even use another serial port on your pc or even run the
program on another pc, just to eliminate any hardware problems on the pc /
cable side. If not, its a problem with SatPC32 and/or its configuration.
Nova does a fine job for my homebrew tracking system.
If its still not working, then its probably a problem with the rotor control
box itself. I assume you tested the rotor in manual mode and it works fine
(meaning that the motor & cable between the control box and the rotor is
ok). In this case I would look into the power supply (if there is an
external one).
Gives you a few things to look into ...

Hello
Further details.? Rotor controller will not talk with computer.? Rotors work
manually, still not working with second computer, tried park, not go,,
satpc32 using a serial port not virtual, satpc32 works the doppler fb on the
910H.? It worked yesterday, however I "rearranged" some equipment in the
shack, no go after rearrangement.? Not sure what the ^%%$#$% I did.?
Suggestions and some guidance please.

I detected no noticible tumble recently. Is this the consensus, or is it so
slow as to be un noticible?
If there is any spin at all, then it will be about the Z axis and thus the
pointing of the Z axis will not change much.
And if it does not change much, and is pointing near the sun, then we woiuld
have little power. If itis poiting closer to 90 degrees off the sun, then
we would have good power.

So has anyone done a spin determination?
I guess this email is pretty useless. I began it thinking (wrongly) that a
Z spin would change its orientation to the sun during each orbit and so we
could determin from the power nulls where it was pointing. But once I got
into the email, I realized that it's spin would be in inertial space and so
its axis to the sun would be relatively fixed (except for any wobble). So
in that case, any change (other than eclipses) in relative sun angle on the
Z axis is going to be very slow changing.. (if I got this right... or not).
thanks
