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 have both a commercial and a homebrew Eggbeater and am disappointed with both, especially in light of its rather high price. Connected to my IC-7000 via an ARR mast-mounted preamp, performance is far less than with an HT and an Arrow. Guess an omni can't cut it, at least not from my QTH.
Maybe if I could get it up higher, clear of all roofs, it would do better. I can make contacts at relatively high sat elevations, but can do just as well with a $10 dual band ground plane. My friend has an Eggbeater and the same preamp at a clearer QTH, and he hears substantially better, down to 10 degrees elevation in some directions.
Good luck and 73,

A Technician class friend of mine and I would like to ragchew between
His QTH in Lindale, TX (32.495164 N, 95.513233 W) and My QTH in
Phelan, CA (34.436400 N, 117.468649 W) with the exception of oscar 0
is anything flying that would enable this on a frequency above 50MHZ?
Doing what I try to do every vacation which is try to spend a little time
back on the birds. I've yet to have a QSO on HO-68. I hear the beacon just
fine. But I just finished my 2nd pass from NJ and was unable to hear any
signals let alone myself coming back on any mode. Did I misread the
operating schedule or am I doing something wrong? MacDoppler told me there
was a good pass to this part of the world are around 21:30 my time. Great
beacon strength but nobody else was home.
The deployment of ARRISat-1 is approaching. Here is a collection of data on
the various modes for use in configuring SATPC32. Note that you will need
to tweak the sideband frequencies slightly to account for rig calibration
and other issues, as usual, but these should be close. You can paste these
in the DOPPLER.SQF file, but before you do, please read on!
Since ARISSat-1 will be deployed by a gentle push from the ISS by
Cosmonauts, the ISS Keps will be good until separate Keps are released by
Space Track. One way to handle the transition is to change the Doppler
Paste the ARISSat-1 data as desired, and also paste the ISS version of the
data into the DOPPLER.SQF file after the regular ISS data. For the final
test aboard the ISS, and initially after deployment, select ISS tracking,
and then select the desired ARRISat-1 frequency data at the end of the list
in the CAT window.
After the ISS and ARISSat-1 are far enough apart that independent Keps are
available, you can begin using ARISSat-1 as a separate object by adding it
to the objects you track in the Satellites menu window. The satellite may
be identified as ARISSat-1, but may well have some other designation which
will be reported. If it is not ARRISat-1, then change the name in the first
group above to that used in the Keps. They must agree exactly for SATPC32
to match the Doppler data with the satellite. (You can also use the
AmsatNames.txt file, which is covered in the SATPC32 documentation.) You
can then delete the extra ISS data if you wish. They won't hurt anything,
but it will clean up the ISS CAT window.
Does anyone have old copies of Orbit magazine they would like to get rid
of? I have been an AMSAT member since mid 1980 and can only find two of
my old copies, Nov/Dec 1980 and April 1981.
I'd like to have more if anyone has some getting moldy in their cellar.
Or point me to an electronic archive...
