I'm getting back into FM LEO's and setting up a station. I will actually
be using a 70cm HT to receive the downlink but I'll be in a base station
configuration. I have no desire to operate portable or "out in the yard"
with a hand held Arrow or similar antenna. The use of the HT is out of
financial necessity. Don't get me wrong, I have nothing against portable
operation and I think the manufacturers should support it. It's just not
for me.
What I would really like to see someone come out with commercially is
something along the lines of the Genesis SDR HF radio kits. If you
haven't seen them, it's a kit for an SDR all mode QRP 40 meter HF radio.
I'd like to see a kit for or even a prebuilt all mode 5 watt 2m/70cm
SDR satellite radio. That would be cool to me.
I know there are SDR groups out there. I wonder if anyone has anything
like that in the works?

Hi,
I probably missed something.... but on AMSAT website, we are able to buy
the LVB Tracker completely assembled, the bare board without any part or
only the enclosure........
What about a complete LVB Tracker.... but as a kit ??
I don't want to save money, I just like to build, when possible, my
hardware.
Is there a place to purchase a complete LVB Tracker (parts and
enclosure) as a kit instead of completly built ??
Thank for your help.

Mark,
Thank you for this thoughtful post. Like many others using today's current
roster of available satellites, I wasn't around for AO-40 or many other
satellites that are recalled her so fondly by those who were.
If I could build, launch and select the orbit for an amateur satellite, I
believe it would be something along the lines of what we've been told about
the Chinese satellite known as XW-1. As I recall, it has an FM repeater, a
linear transponder and a flying mailbox. A satellite with those capabilities
in an AO-7-ish (or, actually, slightly higher) orbit would be one I would
really enjoy.
Even that, however, will take significantly more fundraising than what we
have before us now. I applaud the Board of Directors and AMSAT's officers
for accepting the Engineering Task Force recommendations and moving forward.
My interests - and the challenges and satisfaction I find - in the amateur
satellites are different from many others'. I recognize that the Board and
AMSAT-NA officers inevitably walk a tightrope when faced with decisions
because they won't ever make everyone happy. Consider just what the AO-51
operations team faces regularly when scheduling various modes on her -
that's a very small taste of the dynamic interests that AMSAT worldwide
faces in considering - then acting - on how best to move forward for the
future.
Sumbandilla Sat operation is on the horizon. I presume plans continue to
move forward to XW-1 to be in orbit and available in the not-too-distant
future. We all hope FO-29 will be back to her old self in no more than a few
months. We now have ARISSat-1, the 1U cube sat and?the amateur
communications package in the rideshare opportunity. Even excluding FO-29,
that is a significant increase in operating opportunities on the way fairly
soon. I find that very exciting.
73 to all,
Tim - N3TL

Well, it's nice that you have an amount in mind for how much you would
pay.? Frankly, I'd probably be willing to spend 4x as that much.? It
probably would take that level of funding to get purchase a launch.
As far as I know, the terms of the bid that Arianspace quoted AMSAT-DL
were never released, but we get hints of the it in presentations like:
http://mstl.atl.calpoly.edu/~bklofas/Presentations/AMSATUK2009/3b_Gulzow-P3E.p
df
which suggests that 20,000 euros per kilogram isn't absurd, and they'd
be lucky to get a launch for half that price.? This would yield a
price for P3E of only (!) 1.7 million euros, or 2.5 million dollars
U.S.? AMSAT-DL didn't think such a launch was feasible, and claims
that the costs were (in ttheir words) "one order of magnitude too
expensive".? ? As they say, "bitter" reality of their funding efforts
is that the attractiveness of amateur radio has dropped significantly,
and that funding a P3 satellite from amateur resources alone "seems
not to work now and probably never again?".? In light of this,
AMSAT-DL has pursued tax money from their covernment to pursue a 20M
euro effort to fund launches for P5A and P3E.? I wish them luck, but
in the current economic environment, as well as past experience, I
think there is some reason for skepticism, or at least, no expectation
for a quick resolution to this issue.

I think the reason against such a strategy is quite simple, and it is
absolutely personified in AO-40.? Yes, AO-40 was a remarkable,
amazing, revolutionary amateur satellite.? But radio amateurs put all
their eggs in one basket, and that basket had a hole in it, and all
the eggs tumbled out, and now we are left not only with no eggs, but
with an environment where people might (reasonably in fact) ask why
they should put all their eggs in one basket again, particularly
because these baskets have rocket motors filled with hydrazine and
nitrogen tetroxide inside.? Even if we could fund an HEO launch, I
still think it is a matter of debate as to whether launching these
kinds of expensive, heavy satellites is a project which provides the
greatest utility toward the amateur service.
> Just to be clear my opinion is not against the collective effort and
people works but against some of the objectives they carry. Volunteers
> motivation should be the best interest of all not the few.
I find this statement a bit disingenous.? The simple truth is that
satellites in HEO are usable by fewer, not more hams.? If we really
were trying to provide a satellite which benefitted most hams, it
seems pursuing a strategy which minimizes their personal investment in
ground stations is entirely reasonable.? Despite your assertion that
AO-51 is a mistake, I would counter that it's been enormously
successful: a long-lived versatile satellite that provides interesting
opportunities for people not just on VU but on L and S band.
Bruce (I think it was Bruce) suggested that the cost ratio between a
cubesat launch and an heo launch was around 125/1.? To compare apples
to apples, we'd have to compare the benefits of having 125 cubesats
(perhaps carrying full V/U transponders like the ones designed by
PE1RAH) versus one satellite in HEO.
AMSAT's strategy is I think an entirely reasonable strategy.
Cubesats are a reality: they will continue to be launched.? As yet,
they have not been of enormous utility to radio amateurs because they
carry only the kind of radio payloads that they need to support their
scientific objectives.? But miniaturization has resulted in the
possibility for a solar cell carrying cubesat to carry a full V/U
transponder..? The trick is getting these university and scientific
projects to carry them for us into space, so we can make use of them
when their scientific missions are over.? We can do that by providing
them with a tested radio module that integrates the functions they use
as a standardized item..? This allows them to concentrate on their
mission and not have to design custom radio modules for their cubesat.
This allows them to get to orbit cheaper and quicker.? And, it puts
hardware we can use in orbit.? And here's the best part: we don't pay
for it, they do (modulo our one time costs for developing the hardware
in the first place, which is very minimal compared to the launch
costs).
We'd all like an HEO launch.? But until you can figure out how to
raise several million euros to accomplish the goal, it doesn't seem to
be a worthwhile endeavor to complain about spending a few tens of
thousands on this project.

Hi Mike,
Thanks for your note. And, I suspect, when you entered the hobby back then,
radios like the FT-817 weren't available - nor were effective portable
antennas like the Elk and Arrow.
As you recall, you and I had a contact on VO-52 not long ago that I emailed
you about. I was using AFSK on a 1.5-watt Yaesu VX-3R HT, with a straight
key connected to the mic jack. I just missed a contact on FO-29 before she
went down. I intended to write up something for the Journal about a complete
satellite station that would fit in a briefcase - with the ability to work
all the FM satellites, all the linear satellites (granted, in CW only) and
digipeat packets through the ISS digipeater. I still will write that story
when FO-29 comes back and I can get that contact.
I surely don't begrudge you or anyone who operates from a high-quality,
highly effective ground station. I continue to be disappointed by those who
feel the need for the highest power available on the FM satellites because
it's totally unnecessary and overkill. They keep others from enjoying the
satellites as much as they because the lower powered stations don't have a
chance. That's a moot point on the linear satellites, as we both know.
I apologize if my statements offended you. That surely wasn't my intent.
I hope all is well with you.
73,
Tim

70cm uplinks work better here. We have had issues with newcomers not
hearing the downlinks on 70 and then causing QRM, because they're not
aware there's anyone there. 2m uplinks in this part of the world
suffer from QRM when the birds are over Asia. This affects FM LEOs
worst, the linear transponders aren't as badly affected.
I've long preferred 70cm uplinks (the big reason SO-35 was such a hit
down here).

John. I was told by someone else that the problem was current use...but if
ITAR is the problem, then it can be fixed. ITAR is a pain but it can be
"dealt with" particularly in this case...where there is no dual use
capability.
As for AMSAT's ARISSsat transponder. Well we will see if it works. They
are not exactly burning up the track record with success. We have had this
argument and I am willing to sit back and see if it goes, but it is far to
much project for the program. Most of the folks I know at JSC give it less
then 20 percent chance of working...In fact it was a source of mirth at a
recent BDAY party.

Hi,
AMSAT-UK offer various kits on the LVB Tracker from bare motherboards
(including the TCP/USB interface board) to full kits (enclosure, display,
motherboard and components).
Please check the AMSAT-UK website for details http://www.uk.amsat.org (the
link to the shop is on the left hand side - please select the "Hardware"
sub-link for details on the hardware we have for sale).
Unfortunately, I am currently out of stock on all LVB kits (plenty of
motherboards available though) and am in the process of restocking - the
kits are very popular this side of the pond!
I will announce on this list when I have more stock.

This is the message that must go out from last weekend's AMSAT
Symposium. Acknowledge what can - and can't - be done, and
work on what we can do.
The 1U cubesat project, along with AMSAT working toward an
agreement with the University of Florida and the collaboration with
SUNY-Binghamton, need to proceed and all be successful. All of this
needs support from us - monetary contributions for the construction and
launch of the new satellite, as well as contributions of time from those
who are able to work with the SUNY-Binghamton students as well as
whatever is needed with the Florida efforts if an agreement is reached
there.
Minutes after the end of the annual meeting Saturday, I was signing up
for a life membership. Earlier today, I used the online store to make
another contribution toward this new $100K fundraising goal for 2010.
My skills are not those that are needed for the SUNY-Binghamton project,
so I'll contribute in other ways - monetary donations, plus my time at
hamfests or other events representing AMSAT. By the way, I will be at
a hamfest in Tucson AZ on Saturday (17 October) morning with an
AMSAT table and doing demonstrations on various satellites, which I'll
elaborate on in another message later.
Like many, I'd love to have an HEO satellite. From here in Arizona,
geography limits me to a relative handful of countries I can hear on
our current crop of satellites. I was not on the satellites in the days of
AO-10, AO-13, or AO-40. AO-7 doesn't get me to Europe or Asia
from here. I'm a DXer at heart, so the thought of being able to work
these places via satellite without the lack of propagation getting in the
way is an appealing thought. Until that happens, I'm enjoying the LEO
satellites, working different stations when close to home or on the road,
and the friendships that have come from thousands of QSOs over the
last 4 years. I'm hoping for an HEO bird, and at the same time I'm
getting on the air.
As for the AMSAT board's choice of an FM satellite compared to a
linear transponder, it seems simple to me when I look through my
satellite log over the last 4 years. Many more work FM than SSB. I
wish it wasn't that way, but the data doesn't lie. Drew pointed this
out during a presentation at the Symposium, and his findings mirror
what I see in my own logs. I am lucky to get 4 or even 6 QSOs on
VO-52 or FO-29 on a single pass over the last 14-15 months I've been
on those birds, and that would only happen during a hamfest
demonstration. Admittedly, there are some passes on VO-52 where I
have worked exactly one station - having a nice chat for the entire
pass. VO-52 may be the best of our current crop of satellites, with a
very strong downlink copyable with something other than a directional
antenna (I've used a telescoping whip with my FT-817s to make a
QSO not long ago). It also hears well, and I regularly cut my transmit
power down to 500mW during many passes just to see how well I hear
myself. If I'm looking to work a lot of stations on my road trips, the FM
birds are the only way to go. I'm not going to work 20 or almost 30
stations on VO-52, but that's possible on AO-51 or even the 7-minute
passes on AO-27 are good for sometimes up to 20 QSOs. Rather than
waiting and hoping for an HEO satellite, I am happy to make good use
of what we currently have - while waiting and hoping for an HEO satellite.
The plans for a U/V FM satellite are great, to have an FM satellite but
swap the uplink and downlink bands around. I made 2 QSOs via
SO-35 in 2000, using two HTs with long duckie antennas through that
U/V FM satellite. There are also many QSOs that I've made through
the ISS cross-band U/V repeater when it has been available, also
enjoyable. It will be a nice change of pace, even if it means more of
a challenge in having to deal with Doppler on the uplink instead of the
downlink. I look forward to that.

Yes, some of what was presented looks intriguing, and may be our way
out of strictly LEO orbits.
I apologize if this message is a bit long. After the past year or so, it was
great to see the plan unveiled last weekend by the AMSAT board. Maybe
once we see the fruits of this plan will the radio manufacturers look closer
at adding satellite capabilities to future offerings. It is exciting
to see a plan
which is more than "build one satellite", but lay the groundwork for many
satellites and create partnerships and relationships with universities that
are already building and launching their own satellites. None of this may
be HEO, but we do need to have a plan for more satellites. This plan is
a good one.
73!

As for AMSAT's ARISSsat transponder. Well we will see if it works. They
are not exactly burning up the track record with success. We have had this
argument and I am willing to sit back and see if it goes, but it is far to
much project for the program. Most of the folks I know at JSC give it
less then 20 percent chance of working...In fact it was a source of mirth
at a
recent BDAY party.
