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...).

Dear friends from University of loisiana in Lafayette,
Your bird was heard in the North of France when flying over Oran
(Algeria), orbit number 204, especially the CW beacon (on 145.823 MHz +-
Doppler) between 12:12:52 and 12:13:06 UTC, content was "EUL CAPE 2 OR
UF231". The signal was somewhat chirpy, but it's exactly the sound which
the real lover of CW like above all. Really ! :-)
The signal to noise ratio is not too good because I'm using an old AM/FM
scanner from the 80s heterodyned by my medium wave homebrew transmitter
fitted with a 456.9 Xtal. The antenna was a vertical half-wave inside the
The next orbit, number 205, was heard too, with the CW beacon affected
at that time by a hoarse voice and suffering from a strong fadding. So I'm
not absolutly sure, poor lonesome telegraphist, of my human decoding,
"M5UL CAPE 2 ÜR 5045", something like that. It was over the East coast of
Spain, between 12:12:52 and 12:13:06 :
Congratulation to the Cajun Advanced Picosat Experiment team from France !

Hillbilly Tracking for Low Earth Orbit Satellites
In a video, Travis Goodspeed KK4VCZ describes his Low Earth Orbit
(LEO) satellite tracking system to the 30th Chaos Computer Congress
which took place December 27-30, 2013 at the Congress Center Hamburg
The YouTube description reads:
Satellites in Low Earth Orbit have tons of nifty signals, but they
move quickly though the sky and are difficult to track with fine
accuracy. This lecture describes a remotely operable satellite
tracking system that the author built from a Navy-surplus Inmarsat
dish in Southern Appalachia.
The entire system is controlled through a Postgres database, fed by
various daemons spread across multiple machines. So when I click on a
satellite on my laptop or cellphone, it runs “UPDATE target SET
name=’Voyager 1?;” and the motor daemon then begins to track the new
target while the prediction daemon maintains accurate estimates of
its position in the sky.
Additional daemons take spectral prints or software-defined radio
recordings of the targeted object for later review.
There is a description of the system on Travis Goodspeed’s Blog at

OPDX Interview With ND9M.VQ9JC Diego Garcia
(Here is an interview from the Ohio/Penn DX Bulletin with Jim Clary,
ND9M, known for his amateur radio and amateur satellite operation
from Diego Garcia, and maritime mobile operation. - ANS Ed.)
VQ9, CHAGOS (Update). Last week we reported that Jim, ND9M, is
once again active as VQ9JC from Diego Garcia. Jim informed OPDX
that he arrived on the island a month ago, but he had to get his
license renewed; it expired a couple days before he landed.
Jim states, "Normally, I get it renewed within one business day, but
this time there was an administrative hiccup that led to a month-
long delay. The British military officer in charge of the island -
called the 'Brit Rep' - was new to his post here. He read all the
can's and cannot's of the job, and the legal info about issuing ham
licenses says that tickets are signed by the Territorial Commissioner
who's back in the U.K.
The Brit Rep finally got the official word last week that issuing
authority was delegated to the local office, and my license was
signed the next day. This was the first time in the 15 years I've
been coming here that anything like that had happened. In fact,
licensing had been so smooth here that in 2008, I walked in to the
Brit Rep's office without an appointment and left 45 minutes later
with not only a signed renewal for my regular VQ9JC license but also
a special temporary license for my VQ98JC operation. I wonder if
anyone else can claim receiving two licenses fully authorized with-
out previous notice that fast!
Anyway, I'm still operating Field Day style from the covered picnic
table at the park which has AC power and dozens of gecko lizards
chasing the bugs. The table is about 30 feet from the wall of the
jungle, and this weekend I'll try to thread a 135-foot OCF dipole
through all the trees in the jungle so that I can not only leave
the antenna up but also have multi-band capability. If I hoist the
antenna where it can be seen, I would stand a very good chance of
it being quickly removed as the 150 pound fishing line that I use
to secure the antenna and the copper wire are both precious commo-
The OCF dipole doesn't work on 15m, 30m, or 60m, even with a match-
box, so I'll put up separate dipoles for 15 and 30 and feed those
two and the OCF to a switch. I don't know yet if I'll put up a 60m
dipole. The 80m OCF is going to be a big enough project just to get
it hoisted to only 25 feet; the jungle's pretty thick! I'll also be
putting up a 20m dipole and maybe a 30m dipole as well on the ship.
Obviously, I sign /MM during any contacts made from the ship as I
did earlier this year. Contacts with me as /MM aren't valid for
DXCC of course, but SKCC ops can count them if my ship's QTH is near
The rig is an FT-857D. I'll be running 100 watts most of the time,
but I'm expecting to do some QRP work from here too. Most of my oper-
ating will be CW as usual (with a cootie most times), but I'll be on
SSB occasionally. Also, I'm a rookie when it comes to digital comms,
but I'm hoping to get my Rigblaster and FLDigi software configured
to do some PSK and RTTY work.
While on board the ship, I use an Icom IC-760 that I have set up in
my service shop. I feed the coax through a helicopter control center
that's directly above my shop. My shipboard antennas are about 115
feet above the water line. I don't have internet connectivity when
I'm at my operating QTH on the island, so I obviously can't help
with real-time QSY requests or the ever present 'EU PSE' when I'm
calling for NA & SA stations."
OPDX asked Jim about the status of the club station, possibly using
a special VQ prefix for 2014, activity on the satellites and if he
would attend the 2014 Dayton HamVention, and he replied, "Yeah, the
ham club station is gone forever unfortunately. The log periodic has
been grounded and dismantled, and everything in the shack has been
turned back over to the Navy. I'm here six months out of the year of
course, but once Larry, VQ9LA left three years ago, there was no one
reliably present during my off times. When the Navy's MWR office
personnel made a routine visit, they found nobody there since I was
Stateside, so they decided that the club was no longer in use and
took what they thought were appropriate steps. By the time I got
back to the island and worked my way up the chain of command, the
deal had been sealed.
And yes, I'm working the satellites out here although there aren't
many ops to work. I'll be on the birds when I get home again next
I don't know yet if my XYL Cori (KK4CGA) and I will be at Dayton
this coming May or not. We're hoping to go to New England for the
ARRL Centennial in July, and we'll likely do only one trip. My
assignment schedule has me returning to the ship a few days
before the national convention, and I'm trying to work things out
with the guy that's here when I'm off ship for him to stay a little
longer so that I can attend. He hasn't given me a firm answer yet
My plan for 2014 is to get VQ94JC issued for sometime during the
second half of the year. The local licensing office has no require-
ments toward my getting a ticket other than having one already
issued by the FCC. My US license expires in April, and the FCC
won't enable the renewing process until 90 days before the expir-
ation date, so I have to wait until early January to do that. If
I can get the renewed license here - actually just a scanned copy
will do and my XYL will send that - I can turn that over to the
local office, and they should issue me the short-term ticket.
Emphasis on special. It's all legal of course, but the folks in
that office are all British military who typically do one-year tours
here before being re-assigned, so I can never assume that the next
person will cooperate. I'm optimistic though as I've already had 7
VQ9xJC licenses plus the VQ975FOC ticket earlier this year, so the
precedent's pretty well established. When I started doing the VQ9xJC
bit in 2007, I did it just for fun and I thought the WPX chasers
would like it. I really didn't expect to still be doing it after so
many years. Now I'm looking ahead at rounding out the decade of
annual special callsigns and thinking about what special prefix
variation to initiate after the 10th one!" QSL via ND9M.

Uncoming ARISS contact with Zespel Szkel Technicznych, Ostriw
An International Space Station school contact has been planned with
participants at Zesp?l Szk?l Technicznych, Ostr?w Wielkopolski,
Poland on 08 Jan. The event is scheduled to begin at approximately
10:43 UTC. The duration of the contact is approximately 9 minutes and
30 seconds. The contact will be direct between OR4ISS and SP3POW. The
contact should be audible over Poland and adjacent areas. Interested
parties are invited to listen in on the 145.80 MHz downlink. The
contact is expected to be conducted in English.
The Centre of Technical Schools in Ostrew Wielkopolski is a school
which educates future electronics and mechatronics engineers,
computer scientists and renewable energy specialists. Our school has
been cooperating with Polish universities, electronic and mechatronic
industrial plants and schools in Germany and the UK, what brings very
good results. Thanks to the participation in the ARISS program our
school has partnered with the Space Research Centre of the Polish
Academy of Sciences in Warsaw. Our students participate in various
forms of extra-curricular activities which develop their passions and
interests. As a result, they have created many interesting electronic
and mechatronic devices. For example, some of the recent
constructions include fpv plane, a qudrocopter, a stratospheric
balloon capsule, some amateur radio equipment and many more.
Currently, the school has 800 students aged 16 - 19 years. The
Center of Technical Schools has invited its younger mates (students
13 - 15 years old) from Junior High School No. 1 named of Polish
Nobel laureates in Ostr?w Wielkopolski and 10 - 12 year-old students
from Pope John Paul II Primary School in Lamki so that they all can
participate in the ARISS program. Preparations for the ARISS contact
began in late 2011. A series of amateur radio classes were carried
out so that students could learn the rules of work on the radio. It
was a very interesting experience to carry out radio communications
through amateur radio satellites and to take photos from NOAA
satellites. In addition, we monitored other radio signals from the
space. Most emotions were from the radio contact with the ISS in the
APRS system and from listening to ARISS contacts of other schools in
Poland and Europe.
The schools participating in the ARISS program organized a series of
events to promote various fields of science, particularly those that
are the most relevant for the development of astronautics.
Participants will ask as many of the following questions as time
1. What scientific experiments are carried out on the space station
2. How does the magnetic needle work in space?
3. How do you handle different illnesses?
4. How would a pendulum clock work on board of the ISS?
5. Was there anything that surprised or impressed you during your
stay in space?
6. What was the largest mammal (except for humans) which was on the
7. How do flying insects behave in zero gravity?
8. Do you know how many centimeters your body lengthened in
9. Is it easy to use a pen or a fountain pen on the space station?
10. Do you think that time in space passes faster?
11. How do you observe and explore the Moon?
12. What or how did you feel when you saw the Earth from space for
the first time?
13. Does Kirobo work well and fulfill its mission on the ISS?
14. Is it hard to get used to weightlessness?
15. Is it possible to be able to breed crystals in weightlessness?

Satellite Shorts from all over
SkyCube 2meter highly reflective balloon
The empty gray box shown at the top of the satellite model is
the container that holds SkyCube's balloon. We will command the
ballon to inflate 90 days into the mission.
Most CubeSats are far too small to see from the ground, but SkyCube
will be an exception. The satellite will carry a tightly-packed
balloon, made of 0.35-mil (9 µm) low-density polyethylene, coated
with highly reflective titanium dioxide (TiO2) powder. During the
final phase of the mission, the balloon will be inflated with a 4-
gram CO2 cartridge, and expand to a diameter of nearly 7 feet (2 m).
This will make SkyCube brightly visible to millions of people on the
ground as it passes over the Earth's twilight regions.
SkyCube's balloon serves another purpose. Once it inflates,
SkyCube's orbit will decay rapidly due to atmospheric drag. Less
than two weeks after balloon inflation, SkyCube will re-enter the
Earth's atmosphere and burn up harmlessly. The balloon lets SkyCube
end its mission cleanly, and avoid becoming space debris that could
harmfully impact future missions. SkyCube's balloon was developed by
Global Western, an experienced supplier of aerostats for NASA, JPL,
and others with unique high-altitude ballooning needs.
Further details are available in SkyCube's Orbital Debris Assesment
Report (ODAR), required by NASA and approved with our FCC license,

I notice that the frequency calculated by MacDoppler is slightly off from
the frequency that I hear the telemetry at. It's off by up to half a kHz.
It's not a fixed offset (as I would expect if my Radio was not calibrated
on the right frequency), so I can't just offset the frequency slightly in
Is this expected (within experimental error), or is likely that I have
something wrong with my setup?
It's hard to tell if I have the same offset for other satellites, because a
CW beacon is present even if the tuning is off just slightly. When using a
radio to receive AO-73 (vs the dongle) the tuning needs to be quite
