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.

Hi All,
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
C).
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.

Dear friends from University of loisiana in Lafayette,
Your bird was heard in the North of France when flying over Oran
(Algeria), orbit number 204, especially the CW beacon (on 145.823 MHz +-
Doppler) between 12:12:52 and 12:13:06 UTC, content was "EUL CAPE 2 OR
UF231". The signal was somewhat chirpy, but it's exactly the sound which
the real lover of CW like above all. Really ! :-)
http://f5yg.pagesperso-orange.fr/forum/CAPE-2_orb204_03dec2013.mp3
The signal to noise ratio is not too good because I'm using an old AM/FM
scanner from the 80s heterodyned by my medium wave homebrew transmitter
fitted with a 456.9 Xtal. The antenna was a vertical half-wave inside the
attic.
The next orbit, number 205, was heard too, with the CW beacon affected
at that time by a hoarse voice and suffering from a strong fadding. So I'm
not absolutly sure, poor lonesome telegraphist, of my human decoding,
"M5UL CAPE 2 ÜR 5045", something like that. It was over the East coast of
Spain, between 12:12:52 and 12:13:06 :

The latest news about the launch date and time has just been confirmed by Kosmotras.
The launch date of RS-20B rocket (Dnepr) with a group of satellites
(DubaiSat-2 cluster mission) from Dombarovsky missile area (Yasny Launch Base) has been established for November 21, 2013 at 07:10:11 UT. The
back-up launch date is November 22, 2013 at 07:10:11 UT.
We will shortly be providing prelaunch TLEs and, in about 7/10 days,
the Dashboard software that is needed to demodulate and display the
telemetry information. More information about the Dashboard can found

Hi Folks,
FUNcube/AO-73 is now in continuous transponder mode with low power beacon,
as at 19:15 UTC. Change back to Auto eclipse mode planned for Sunday PM UTC.
Enjoy the transponder

That is why I want so much to continue the 145.825 digipeater on as many
satellites as we can*.
But we can’t seem to inspire any of the other HUNDREDS of satellite
building groups to consider it.
I think there were over 100 cubesats launched last year. None with 145.825
APRS…
*(and convince the leave-it-on-24/7/365-not-moving user satellite stations
to stop beaconing unattended!)

Too bad we can't get the balloon to switch to the ISS frequency and use the
digi off of it when over the oceans and arctic!

We're a tough crowd to please...
First circumnavigation of the globe by an amateur radio carrying
balloon, and as it passes the milestone...
"So, can you get another lap out of it?"
What about poor old M0XER-3? It's still out there! Sure it got waylaid
in Nunavut for a while, and let M0XER-4 slip on by... It needs some
encouragement too!
[ see present track: http://aprs.fi/M0XER* (and click for 7 day tail)]
If the winds are playing nice, and the fates allow, it should be
coming into range fairly soon.

Hello to the group……..
Does anyone have the specifics on how to setup two IC706 MKII-G’s for satellite ssb/cw operation (duplex).
I’ve done a bit of browsing and read the manual but remain confused on the hardware needed when using
my Compaq laptop (no serial port), only USB’s.
Any advise would be appreciated.

Has anyone tried one of these for portable use ? It has cross band repeater
and also functions in Full Duplex.
I just ordered one but need to get another hand held antenna, when I do I'll
post my findings.
