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.
Here is some additional Mars Landing news which is probably more useful now
rather than waiting for the next weekend AMSAT News Service cycle ...
NASA is offering a web page with the Mars Science Laboratory Landing Toolkit
Landing: 5-6 August 2012
10:31 pm Pacific, 5 August
11:31 pm Mountain, 5 August
12:31 am Central, 6 August
01:31 am Eastern, 6 August
05:31 am Universal, 6 August
The page includes links for web streamed live landing coverage, mission
information, and public relations.

AO-7 was in Mode B and performing like it used to. It
obviously had more power and although you could make it
FM, the bird handled it with grace. It was workable to
the north of my qth over the NWT which is not usually the
case. Let's hope it stays in this condition for many years
Attention satellite ops/enthusiasts in the Dallas/Ft. Worth Texas area.
The National Scouting Museum in Irving Texas is on the docket for an Amateur
Radio on the International Space Station contact in connection with the 55th
Jamboree on the Air (JOTA) Ham Radio/Scouting event. The contact is
scheduled for October 20th but the time is still TBA. Keith Pugh, W5IU is
the ARISS mentor and facilitator between the Museum and ARISS/NASA.
The lead group running the JOTA activities is the Irving Amateur Radio Club
of which I am a member. Ham participation is however open to all interested
parties. Doug Quagliana headed up an AMSAT display and ran satellite
contacts for last year's JOTA at the Museum.
I am holding a planning meeting for all interested Amateurs and Scouters to
get a handle on what types of activities we can create and staff for this
event. The hope is that several hundred or more Scouts and adults will be
coming through the Museum for the ARISS contact and participating in various
radio and electronics activities.
Meeting will be at 11AM this coming Saturday in Irving. Contact me directly
if you are interested and I will give specific directions to the meeting
location. Even if you cannot attend this meeting but are interested in
participating in JOTA activities, I need to know so I can put you on a mail
list and ultimately schedule you for setup (Oct 19) and JOTA operations.
Please email n5hyp(a)amsat.org and I will be grateful.

I don't have them written down but I can probably figure them out by
using a Japanese voltage chart [that's a working unit on which you
measure the voltages :) ]. I have repaired several of the boxes recently
and I am pretty familiar with the G-5500. You can email your questions
to K5VOU(a)amsat.org or we can do a video call on Skype if you like.
I am the happy recipient of Satellite WAS # 332 and I want
to express my thanks and appreciation to all of our great
Satellite Ops, working from home and portable, to make this
award and others a possibility. I fully realize where the
credit should go!
