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...).

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,

Would someone more familiar with wikipedia please edit the photo currently claimed as AO-51 in that entry? I'm not sure what satellite that is, maybe one of the SaudiSats, but it's not 51. The error was carried over to this month's QST even.
http://n4hy.smugmug.com/AMSAT/AO-51-ECHO/02-Preparing-ECHO/042-CIMG1769/108… is a good shot of AO-51 just before launch.
Thanks, Drew KO4MA
Has anyone designed a QSL card back for satellite operators who
operate a lot of rover? I am trying to trim cost and time associated
with multiple cards to QSL my rover contacts. In the past I have hand
written many /P cards and some image-based cards using photo printers,
but would like to order a better quality card with an image front and
QSO data on back.
I'm looking for a QSL card back that has room for pertinent
information such as my rover grid, satellite, and the necessary items
to confirm a valid QSO for award purposes. The idea would be for the
card to support at least four QSO's.
My question is -- has anyone designed such a card and are you willing
to share with me your image? Perhaps someone is a real graphics hound
and would like to help?
Thank you & 73,
I was out in the yard getting something out of the car tonight, and as I am wont to do, looked up at the nice clear winter sky. I noticed something moving W to E, nice and bright. Although the path was similar to airliners coming in from the Gulf to Tampa International, this wasn't a plane. Nor was it ISS, as Pocketsat3 quickly confirmed. The straight W-E movement, and my location at 28 and change north, suggested an orbit of similar inclination. It plainly blinked out just before 19:41 local, just as it was approaching Gemini. My gut reaction was maybe the new Chinese mini-station?
Heaven's Above made it easy to search for visual passes, and the best match was an obvious one. Hubble Space Telescope matched my observations, with a max magnitude of 0.7. I had no idea it was so bright!
Just a neat experience I thought some satellite types might appreciate, and it all happened by accident from just looking up.

NASA, UNIVERSITY OF MARYLAND INVITE PUBLIC TO ASTRONAUTS' DISCUSSION OF RECENT INTERNATIONAL SPACE STATION MISSIONS
WASHINGTON -- NASA and the University of Maryland's A. James Clark
School of Engineering invite the public to a discussion with three
astronauts from recent International Space Station expedition
missions at 5:30 p.m. EST on Tuesday, Feb. 14, in the Hoff Theater
inside the Adele H. Stamp Student Union. The crew members will give a
video presentation about their mission and answer questions from the
Free tickets will be available on a first-come, first-served basis.
Tickets can be picked up from the Stamp Union ticket office daily
between noon and 10 p.m., starting Monday, Feb. 6. Reporters
interested in covering the event should contact Missy Corley at

Mike Fossum served as a flight engineer for Expedition 28 and as
commander for Expedition 29. During his stay, the station celebrated
11 years of continuous residence and work. Fossum returned to Earth
on Nov. 21, 2011. He has logged more than 194 days in space,
including more than 48 hours of extravehicular activity (EVA) in
seven spacewalks. He is seventh on the all-time list of cumulative
Ron Garan served as a flight engineer for Expeditions 27 and 28. While
aboard the station, Garan continued work on a variety of microgravity
experiments and welcomed two shuttle visits, including the last to
the station. Garan landed on Sept. 15, 2011. He has logged more than
178 days in space, including 27 hours and 3 minutes outside the
station during four spacewalks.
Cady Coleman served as a flight engineer for Expeditions 26 and 27.
She was the lead robotics and science officer. While aboard, the
station hosted a record number of visiting spacecraft: five vehicles
from four space agencies. She returned to Earth on May 24, 2011.
Coleman has logged over 4,330 hours in space aboard the station and
space shuttle Columbia.
The trio also will give a presentation earlier in the day to NASA
employees at 10:30 a.m. in NASA Headquarters' James E. Webb
Auditorium, located at 300 E St. SW in Washington. The presentation
will air live on NASA Television and the agency's website. The
astronauts will be available for media interviews from 9 to 10 a.m.
Journalists must call 202-358-1100 to attend the presentation or to
schedule an interview.
