Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Has anyone located a driver for the LVB Tracker internal USB to serial
port adapter on Windows 7 x64?
If not, has anyone reverted to the serial port connection on LVB Tracker
and used an external USB to serial port adapter successfully with
SatPC32 on Windows 7 x64?
I have an Edgeport multiple USB to serial port that has drivers for
Windows 7 x64 that I will use if I have to. I would prefer using the LVB
Tracker with its USB to serial adapter if someone has another solution.
Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to
get some telemetry packets. The satellite would remain on for less
than one minute after being commanded on. A quick test of the "bent
pipe" voice mode repeater was successful. . The "hardware watchdog
timer problem" is still evident; as expected, spacecraft temperatures
are insufficient to keep the transmitter ON (needs to be above 15 deg
Orbit projections suggest that satellite illumination conditions will
not result in increased temperatures for nearly 10 years. Command
stations do periodically turn AO-16 "ON" to check on its condition and
see if the hardware timer problem has "automagically" fixed itself
(which in not anticipated, but who knows...).

Here is another teaser :) Several months ago I commanded the AO-16
S-band transmitter ON; it too remains functional (albeit weak), and
was received by me, Drew KO4MA, and Alan WA4SCA.

In addition: Good reception of sat carriers (+/- 2320.190 MHz)
with AIDC3733 2400>144 converter (was modified for AO40 rx):
receiver set at +/- 64.190 MHz (instead of 144.190)

Hello all; for information here in south west Europe we use 2320,100 to
2320,300 cw/ssb portion of 13cm band for tropospheric , AS , RS, traffic.
I have been told by Piero I5CTE
there is permanent continuous carrier beacon around 2320.190 MHz (+/-
doppler) by 1 of the 3 Sirius elliptic NA satellites.
It appears reception is very good here with small 20 turn helix
antenna (in spite of 12m heliax coax) peaking 539.
Apogee (50000km ) around 325deg with 27deg elevation.
F5BOF reports same signal with small hand held 25 elements f9ft yagi.
So these are for us very interesting beacons. Depending hours we can receive 1 o 2 sats.
Real time positions (Sirius-1 / Sirius-2 / Sirius-3) here:
Any info about beacon sat polarisation and eirp ?

Just a note to wish everyone well for the forthcoming year and to thank all of those who are contributing in so many different ways to ensure the future success of the amateur satellite world.
Thanks are also due to the many who contribute to the vital educational outreach work which is so necessary for future generations
Hopefully 2013 will turn out to be a bumper year for new launches!

Tomorrow I will be heading north from em21 through several semi-grids arriving back at my home late on the 1st. I am not going strait home so I might be able to work the sats from the following grids em 08/09/11/12/13/14/15/16/17/18/19 and en00/01/10/11/20 and a few more.
I am going to try to hit as many grids as I can but due to the long drive times and the satellite pass times I might have to skip a few here and there.
Look for me on all satellite passes on the 31st and 1st.
Happy New Year!
