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.
I will be making a quick trip to Arkansas tomorrow and will try working the following passes depending on weather...
SO-50 - 09/29/2011 @ 1726z - EM25
AO-27 - 09/29/2011 @ 1743z - EM25
AO-27 - 09/29/2011 @ 1919z - EM26 possibly EM25/26 grid boundary.

This bb never fails to amaze me with how helpful folks can be.
It was G0SFJ's postings about ARISSAt-1 MET time which set me thinking about the
width of the half shadow (Penumbra) experienced by the satellite before and
I was pointed to the simulation option in the satellite tracker Orbitron 3.17
which shows the selected satellites Eclipse condition
No, Penumbra, Umbra. To activate this option click on the data tab at the bottom
of the satellite listing.
The simulation mode offers a variety of time steps down to 0.25 seconds.
Selecting the ISS and stepping through an eclipsed part of the orbit tonight I
estimated that it took the ISS 8.75 seconds to cross the Penumbra.
If 7km per second is about right for the ISS then the Penumbra is 59.5
kilometres wide +/- about 1.75km.
My workings may well be adrift but you get the idea.
What an interesting utility, for us telemetry nuts it will add an extra
dimension to solar panel data.
Off to try it on some higher flying birds.
