Greetings,
NASA's next rover to Mars, the Mars Science Laboratory (MSL),
is running over budget again, and now NASA is looking to
borrow money from other planetary programs, including the
International Lunar Network, to make up the difference.
If this occurs, the ILN will be delayed from its original 2012-
2014 launch date.

Ulysses was switched off because it exhausted its fuel supply. Without
attitude control fuel it cannot keep its antenna pointed to Earth. Exactly
what are we amateurs supposed to do with this bird when its own flight
controllers cannot communicate with it anymore?
We hams do have a long tradition of making use of other people's useless junk,
whether it was the wavelengths shorter than 200 meters back in the 1920's, a
big pile of war surplus radios in the 1940's, old TV power supplies and sweep
tubes in the 1950's, unused launch vehicle capacity in the 1960's, and test
flights of new launch vehicles in the 1980's. However there are limits to the
"use other people's junk" business model and we have run up against those
limits.
Even amateur radio communications is sufficiently complex to require a
purpose-built payload for our communications mission. Commercial
communications satellites are kept in revenue service until they run out of
fuel, and their commercial payloads are specific to commercial missions and
cannot easily be retuned to ham radio bands at the end of their commercial
life.
The amateur satellite movement started in 1961 when some unknown Air Force
general allowed Project Oscar to attach a secondary payload to a classified
Corona imaging satellite. In doing so he took a big chance on us. If Oscar-1
had vibrated loose from its clamp band and rattled around inside the payload
shroud to bang up the very expensive spy satellite it probably would have been
the end of his career. Following that beginning we went on to launch Phase 3A
with a solid fuel kick motor, and three more Phase 3 birds with highly toxic
and corrosive hypergolic liquid fuel systems. If we had screwed up any of
those missions we had the capacity to destroy the primary payload or cause the
loss of a very expensive test mission with great loss of revenue to the launch
vehicle owners. We were allowed to do these things because of a very generous
and trusting relationship by officials of the launch vehicle authority, who
were also willing to absorb substantial costs of paperwork certifications by
their own engineers that our secondary payloads would not pose a risk to their
primary missions.
Our business model of the past 45 years seems to be no longer viable. In this
modern era the beancounters are fully in charge and insist on full recovery of
any additional costs that are imposed by our presence on the mission. It is
simply no longer possible for a friendly Air Force General or civilian project
manager to allow us to sneak our little payload in under the radar. Our
success in the small satellite area has created a thriving market for small
satellites, and launch vehicle owners now understand that they can sell the
excess capacity that they once gave away for free. With dozens of
universities, small companies and government agencies clamoring for secondary
launch vehicle space, we hams can no longer sneak our little satellites in as
"ballast" like we did in the past.
We did have a deal with Intelsat to carry ham gear onboard one of their
geosynchronous satellites and we would not even need to wait 15 to 20 years
for the satellite to complete its commercial mission before using our payload.
They quoted us a price tag of about $10 million to cover their integration
costs in installing our equipment into their satellite. They probably would
not be making money off of us at that price, merely recovering their costs.
Since we have not yet been able to raise $10 million it looks like this
project is not going to happen. My guess is that the US Government is not
going to fork over $10 million for a disaster communications system unless
they set the specifications and control its use. It would be a classic case of
"Not Invented Here" syndrome.
What can we do to keep Amsat alive in the future?
1. Team up with other space organizations. The Planetary Society is interested
in building a solar sail demonstration mission. Like us, they must find a
secondary launch. Amsat could provide a communications package for the sail
mission. There are other private groups trying to reach the moon. Offer them
our expertise in space radio communications systems, which no other space
interest group can match, in return for a ride on their spacecraft. Amsat has
historically marketed itself as a ham radio organization, but we are also a
space interest group. We should have a presence at the Space Development
Conferences. Few private membership funded space organizations have our
historic track record of success.
2. Offer RF equipment to the student Cubesat groups. Many of them simply
package commercial HT's into their Cubesats, they do not have enough RF
knowledge or experience to do any better. Develop a drop-in RF command and
telemetry system, include a simple transponder capability, and offer it to the
Cubesat groups for inclusion into their satellites. Design and fund an Amsat
Cubesat mission to show them how it should be done. Cultivate relationships
with schools and universities. The aerospace industry is throwing millions of
dollars into development of a new generation of aerospace engineers to replace
the aging and expensive baby boomers who they plan to forcibly retire in the
next few years. A student-built satellite can attract industry funding that no
Amsat mission can ever hope to receive.
3. Cultivate our relationship with NASA, the Department of Defense and Foreign
space agencies. Our presence on the ISS is very costly but NASA thinks that
our value in providing school group contacts through ARISS justifies their
cost to carry us along on this mission. If we are ever going to get to the
moon it will have to be done in the same way. We need to cultivate
relationships with people who can give the green light to future projects like
ARISS. We should try to invite these people to the Amsat Symposium in
Baltimore this October. The private sector is probably not going to help us
unless we can pay cash up front, but always keep your eyes and ears open in
case there is an exception to this rule.
4. Develop our own propulsion technology, possibly electric propulsion,
possibly an old-fashioned solid fuel kick motor. Launch our satellites to LEO
on the Russian missiles, then raise their orbit to a higher altitude. I am
hopeful that the recently announced arms reduction agreement between the US
and Russia might free up additional missiles for launching satellites, however
the Russians have also learned the true value of their missile launches so
even these may be beyond our means without teaming with other organizations.
5. Recognize that the real work happens behind the scenes. Stop whining on
Amsat-BB about what "you guys at Amsat" should be doing. Each of us can take
one of three roles, 1. Lead, 2. Follow, or 3. Get out of the way.

In celebration of the 40th anniversary of the first manned moon landing, the
special event callsign VE3MOON will be operating from 14-27 July. We will
be operating satellites from the Canada Museum of Science and Technology
during much of this period, usually between 1400 UTC and 2000 UTC. We will
also be working HF from various locations throughout the duration of the
event.
We do not have a set schedule, but we do have multiple radios and operators.
Popular satellites among our operators are AO-51, SO-50, VO-52, FO-29, and
the ISS.
There will be a QSL card for this special call. QSL management is through
VE3OIJ.

That is the easy question.
When Gywn Reedy, W1BEL (sk) and others set the specifications for the external
contractor build of the PacComm PSK-1,
they elected to use a common pin assignment/cable (late 1980s/early 1990s) for
the 8-pin mini-DIN (rear panel of PSK-1)
to the RS-232 (DB-9) on your computer.
The cable for usage between an Apple computer and an Apple LaserWriter (serial
port).
I picked up a PacComm PSK-1 in May, replaced a blown capacitor on the 7805
regulator input and
built this serial cable for connection to my personal computer's serial port.
IF PacComm no longer sells this cable (you have to send an e-mail request to
Linda), then any good Apple
dealer or cable supplier should have this cable in their inventory for less
than $25.

Hello Myles,
I have one LVB tracker interface under Yaesu G5500 rotator, is not installed
outside yet, what I have idea to do this weekend, but i can tell you I have
made 1 week tests inside home and I liked very much the precision and
performance under NOVA for Windows.
Easy, no external DC supply needed, and very simple to program and setting
up. LCD show me azimuth and alevation where antena is and where she goes.
I can take photos and sent you this evening.
Best Regards,

Hello John and Greg--
John--I think he means the 8pin DIN, not the mini-DIN....
Greg--contact me off-list and I'll try to help you with the PSK-1T
(even though you apparently outbid me for these items, assuming you
recently obtained them ;-) ) I've been using it to command
AO-16... I don't know about the DFM unit, other than I think it is
probably 1200 and 9600 baud capable.
The PSK-1T can, as a stand alone unit, be used for 1200 baud PSK
packet (like AO-16, IO-26, DO-64) and 1200 AFSK packet (like
CalPoly-6). The DFM TNC doesn't need to be connected to the PSK-1T
for it operate.
If, however, you have a PSK-1 (without the "T"), it requires another
TNC to be interfaced to it (like the DFM, an MFJ, etc.).
My hunch is that the pair was used to add 9600 baud capability to
somebody's satellite station...

Mark N8MH

Hey everyone,
The special call sign K5E will go active on AO-7 at 13:32 UTC on July 16,
2009, and will remain active on the FM and CW/SSB satellites, NO-44 (if
operational) and the ISS in packet or voice (if either system is active)
through 16:50 UTC on July 24, 2009.
Those dates and times coincide with the duration of the Apollo 11 mission to
the moon, which began 40 years ago next Thursday (July 16). K5E seemed the
perfect choice for a special event call sign to celebrate the 40th anniversary
of ?one small step for man ? one giant leap for mankind.?
K - the 11th letter of the alphabet.
5 - the call district of Houston, location of Apollo 11 Mission Control.
E - Eagle, the Apollo 11 lunar module.
On passes I work using the special call sign, I will ID as ?Kilo 5 Eagle.?
Glade Schroeter, WA3MVQ, is donating high-quality full-color QSL cards, which
will be used to confirm all contacts with K5E. Stations wishing to confirm
will send their request to me with an SASE. The card will be standard QSL
size. I encourage any of you who need QSL cards now or in the future to visit
Glade?s Web site at www.gggraphicsstore.com. I custom-designed the card,
which features the Apollo 11 crew patch and a collage of photos representing
highlights of the full mission, from liftoff to splashdown. I will have a lo-
res copy of the card front posted to my QRZ.com page no later than Monday.
Work K5E one time to claim a special QSL card. There will be no endorsements
of any kind, and only one QSL will be issued per valid amateur call sign.
Remember, WA3MVQ is donating these high-quality cards.
This special event and operation will occur ONLY on the amateur satellites.
Another group has organized the Echoes of Apollo program and will have a
number of HF stations on the air during the weekend of July 20th, the date of
the lunar landing. They also held a special EME event over Field Day weekend.
I have no interest in creating any animosity with the Echoes of Apollo group.
I?m just interested in giving us satellite operators the chance to celebrate
the Apollo 11 mission and its 40th Anniversary. I hope as many of you as
possible will join me.
I may contact some other operators around the U.S. and ask them to work a pass
or two over the 9-day operation using K5E so we can cover as much ground as
possible.
Also, please note that the Canada Museum of Science and Technology will
operate as VE3MOON from July 14-27, per a post earlier today to the AMSAT-BB
Thanks in advance to all.

Hi,
I am using the LVB Tracker since few months now, with automatic tracking
controlled by SATPC32 (on a lap top running Windows XP, connected directly
to the LVB Tracker via USB) with absulutely no problems...
The antennas are controlled by G-5500.
By the way, the SatPC32 SW also controlls hre an ICOM IC910H via CAT through
a USB to RS232.

Myles,
I have had one of the original LVB units AMSAT made as the fundraiser(visit
AMSAT website to purchase). It has worked flawlessly. It is a bit of a
challenge to put it in place and calibrate if you have NOT ever set up
something like this before. I have had many experiences doing so and it
didn't take long for me to have it up and running. Putting the USB software
to run it via your computer may take some re-reading of the instructions but
it all comes out easy and simple to let happen.
I use this under PCsat32 and also NOVA. Tracks fine.
I use a second one to demo at hamfests with a portable setup to show how it
functions. I also did this at Field Day for my local club with the help of
another AMSAT veteran.
It has been a great addition to my shack to make it one less thing I have to
worry about while making these LEO passes work.
P.S. I can't wait for an HEO to buzz up the satellite activity- I'll be at
Sussex County, NJ Hamfest 7/12/09 to demo this WX permitting.

Hi Myles,
Simply stated---this is a very functional and easy to use track box,
with exceptional attention to construction detail when purchased
already assembled by AMSAT (thanks, Mike Young!). It's a very fair
price at US$200. (Price out the parts to build one up...it's a deal).
It's essentially plug in, calibrate, then play!
I have (thanks to my long time elmer, Gene KC4SA) built a couple
different homebrew tracking boxes since the late 1980's. The first
used the parallel port to count "clicks" of the U100/U110 rotators.
The latest incarnation uses a BASIC Stamp2 and G-5500. (I think a bit
of research will show that our SAEBRTrack box was one of the first, if
not the first, to make use of the PIC controller concept (built into
the STAMP2) for a trackbox...). All of this is merely to say that I
bring a reasonable perspective into the conversation...
For the past several months, I have been using--by choice--the LVB
Tracker! It's a great little box...currently using SatPC32 with the
G-5500.
In: summary--highly recommended!
73,

Um...I think I got the names swapped in my note sections below...sorry
for the mix up :)
John--feel free to contact me offlist for any help with this TNC.

Hello John and Greg--
John--I think he means the 8pin DIN, not the mini-DIN....
Greg--contact me off-list and I'll try to help you with the PSK-1T
(even though you apparently outbid me for these items, assuming you
recently obtained them ;-) ) I've been using it to command
AO-16... I don't know about the DFM unit, other than I think it is
probably 1200 and 9600 baud capable.
The PSK-1T can, as a stand alone unit, be used for 1200 baud PSK
packet (like AO-16, IO-26, DO-64) and 1200 AFSK packet (like
CalPoly-6). The DFM TNC doesn't need to be connected to the PSK-1T
for it operate.
If, however, you have a PSK-1 (without the "T"), it requires another
TNC to be interfaced to it (like the DFM, an MFJ, etc.).
My hunch is that the pair was used to add 9600 baud capability to
somebody's satellite station...

John -
That is the easy question.
When Gywn Reedy, W1BEL (sk) and others set the specifications for the external
contractor build of the PacComm PSK-1,
they elected to use a common pin assignment/cable (late 1980s/early 1990s) for
the 8-pin mini-DIN (rear panel of PSK-1)
to the RS-232 (DB-9) on your computer.
The cable for usage between an Apple computer and an Apple LaserWriter (serial
port).
I picked up a PacComm PSK-1 in May, replaced a blown capacitor on the 7805
regulator input and
built this serial cable for connection to my personal computer's serial port.
IF PacComm no longer sells this cable (you have to send an e-mail request to
Linda), then any good Apple
dealer or cable supplier should have this cable in their inventory for less
than $25.

Hi I was wondering if some one has any manuals for the DFM TNC and
the PSK-1 or the the PSK-1+?
To get me going can some one please send the pin out for the radio 8
pin DIN for the DFM TNC.
Thanks de John K0CQW
