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.

...and there was much rejoicing.
Trying to get back on the satellites after many (10 year?) hiatus.
[Yes, I missed AO-51, Arrisat, and a lot of the earlier cubesats.
Sigh.] Trying to use SatPC32 to control my Icom 821H and I was seeing
weird behavior and having trouble finding and staying tuned on my
downlink. Manual control worked fine, but I wanted the computer
taking care of some of the work for me. Finally noticed that the
frequency jumps were EXACTLY the default repeater offsets used when
the rig is in FM/repeater mode. No idea how the satellite section got
that way (hidden menu triggered? stray bit flip?) but it happened
whenever SatPC32 sent frequency corrections (either automatic Doppler
correction from the software or tuning via keyboard commands) while I
Solution was a full reset of the radio. Satellite mode works as it
should, confirmed by some nice, computer-supported voice QSOs on AO-7
and VO-52 this evening.
So, to summarize (and hopefully make it easier for anyone searching
amsat-bb in the future if they run into this):
Problem: Icom 821 in satellite mode. Sub-band transmitter frequency
jumps +600 kHz (2M) or -5 MHz (70cm) while transmitting in CW, SSB,
and FM, as soon as software sends a frequency correction to the radio.
No jumps or problems when just listening and tuning across
transponder. Manual satellite mode (software control off) behaves
normally. Manual does not indicate satellite mode has a repeater
Solution: Full reset of radio, reconfigure radio as needed (interface
baud rate and verify address) for software control.
Thanks to the folks I contacted direct (searches of amsat-bb archives
for SatPC32 and Icom 821 issues) for their suggestions and
encouragement. Sometimes a problem that appears to be between the
radio & the computer or software is due to the radio, not the
73, hope to work many of you on the birds.

I think I had a very small signal from Williams beacon frequency.
Pass with AOS here in Copenhagen 1422 UTC - but just 1 degree of elevation
in my worst direction.
Hope I am right.
Should be a good pass over NA in a few minutes.

They have been great ambassadors for ARISS and I have enjoyed listening to
some of their contacts.
I wish them a safe return.
