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.

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 ! :-)
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
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 :
Congratulation to the Cajun Advanced Picosat Experiment team from France !

Just tried to work through AO-73 (22:00) - managed to hear myself briefly,
but way off the normal uplink frequency, I had to tune 11Khz higher than
normal, then signal suddenly disappeared?
Did anyone else experience this?

I think you may have your times off Paul... I show passes over North America for May 1st at 0940 and 1115 EASTERN time (EDST). =^( Which only makes sense, because the 0930Z-1400Z operating period would need to coincide with passes over EU for people to be working LY5N.
Otherwise, I'd be outside waving my yagi around looking for you. =^D

Does anyone know of a USB interface to control azimuth on one of those basic Radio Shack T.V. Antenna rotors? in my search I have only found only older parallel port versions. Thank you all in advance, 73, Keith

AMSAT-UK sends readers to N2YO and he agrees...
