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.

I'm ploting altitude of five CubeSats which were deployed from ISS.
The results is interesting. First deployment satellites are lower
altitude than laters. I guess this is related to initial velocity at
deployment order: #1 WE WISH, #2 RAIKO
altitude: WE WISH < RAIKO
deployment order: #1 TechEdSat, #2 F1, #3 FITSAT-1
altitude: TechEdSat < F1 < FITSAT-1
I'm also ploating ARISSat-1 on the same chart as its time line align
to the five CubeSats deployment date. The chart shows five CubeSats
have large decay rate than ARISSat-1.
You can see the chart on the following URL.

I have just returned from the AMSAT conference in Orlando FL one of the
European is no longer flying the Clyde Space batteries because of
performance issues. I would like to know the group thoughts on their
batteries and lithium batteries in general.
The AMSAT team is warning us about charging batteries below 0 deg c. In
talking to many teams on ElaNa 4 there does seem too much concern about
charging batteries cold. Please let us know your thoughts. If you desire we
will not publish your responses.

I made it home an hour ago, after a great week in Florida. The
AMSAT Symposium was great, and thanks to all of those who worked
to put on this event. And, of course, having Hector CO6CBF at
the Symposium made this even better.
On my way home from the Phoenix airport, I stopped at my mailbox.
I had more checks and money orders sitting in their for the so-
called "Hector fund" that arrived in the past week. Again, many
thanks to everyone who has sent or given me contributions to help
with the expenses for this trip. It is obvious that this was
extremely successful - just watch the video from Hector's
presentation on Saturday to see that.
I have incurred expenses related to bringing Hector to the Symposium
totaling $2413.30, and received contributions totaling $1960.00!
The expenses totaled a little more than I had originally estimated
(I was working with an estimate of $2000 in the beginning), but I
never thought I would have received almost $2000 in contributions!!
If there are other contributions in the mail, I will add that to
my spreadsheet and post an update later. I don't think I will need
any other contributions toward this effort. THANK YOU ALL!!!!!!!!
On my way home from the airport, I called Hector. He made it home
OK, and is now in the process of clearing the gear he brought back
from Florida through the processes of Cuban Customs and the Cuban
communications ministry. This is normal, and he was confident he
could get everything cleared without incident. Hector also said he
hopes to be able to post a message here on the -BB tomorrow, in part
to thank everyone that helped make his trip to Florida possible.
Back to pulling more photos from my camera and mobile phone, and
getting caught up on things before going back to work tomorrow.
Hi JoAnne, K9KJM
C/c Gould Smith, WA4SXM
Congratulations JoAnne !
Thank you very much for your message and I am confident that you
will do a nice job as the new Editor of the AMSAT Journal because
you have already the long publisher experience as the Editor of the
AMSAT News Service Special Bulletin.
I believe that you have a great job to do collecting all non published
material that you should received back from Doug, W5BL
I am worry that my emails will be rejected by your server comcast.net
because there is not compatibility between comcast.net and my server
tin.it and so if you have another email address please let me know.
The problem is not from USA to Italy but from Italy to USA and this is
why I am sending to you this message also via the AMSAT-BB net.
I wish you a nice job as the new Editor of the AMSAT Journal and
with the new numbar of the Journal after the last issue published in
November/December 2011 !
Thanks again for your time and greatings from Naples Italy
