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.

After several frustrating hours of trying to get the software set up
properly, I finally managed to
get Packet Engine Pro and UISS working in time for a good pass of the
ISS over the Southeastern US.
It was really something to see the software display stations and plot
them on a map as the ISS passed
overhead. Even more so to see my own callsign digipeated through the
Next up is to attempt a full fledged QSO through the ISS in real-time.
My special thanks to Joanne Maenpaa, K9JKM whose paper on working
through the ISS using software was
I used my Icom IC-910H with a Signalink interface instead of a hardware TNC.
Having a blast on the birds, and this just adds a whole other element of
fun to the process.

I'm sure this has been covered, I just can't find some detail.
I'd like to consider taking a pair of say 3, 5, or even 11 element 2M
yagi's (off the shelf) and put them on a boom on either side of a rotor,
with nonconductive cross support boom, rotating the boom's to offset the
elements 90 degrees.
Question I have, what would the spacing be between the two yagi's ?
Jerry has done this with success on 2 meters:
It would be great to refine his good work with the spacing for the 2 booms.
(Then I may compare with putting all the elements on one boom)
I like the collaborative nature of the discussion here.
I am working on a summer project with students at Montgomery College,
Rockville. The project is to design and build a device that controls a
pair of inexpensive satellite TV rotors. And the device would emulate a
popular AZ-EL rotor such as a Yaesu G-5500 AZ-EL controller so it can be
used by a satellite tracking program such as SatPC32. Tom, K3IO
suggested this project at the last AMSAT-DC workshop and is guiding us
with this project.
I would like to borrow a Yaesu G-5500 AZ-EL controller and rotor for
about three months or buy a used one so we can study and understand its
I will pick up or pay for shipping. Please contact David, W2LNX
