That's a great point, John, and an interesting analogy, which I'd not
heard about before. Does anyone have recollections and experiences
with AO-24 that they could share?

Hello
With the cost of a launch bouncing around the bb.? You might ask yourself,
"how much did?I? c ontribute to AMSAT in 2010?"? Just did my taxes and?
though not a huge amount it was deductable.? I believe, "if you use it, you
should help pay for it".? This is rocket science and that, ain't cheap!

It's really not that bad. On HO-68 or AO-7 you get at least 3x that
time. FO-29 varies, but it also provides quite a bit of time. And
there's a distinct lack of a 'crowd' on the linear birds. Even on
VO-52 you can have a nice conversation because you can hear
horizon-to-horizon.
The LEO scene is a different set of challenges, but they can be fun to
overcome, and the same kids who are interested in the keps will
*really* love to hear their own voice bouncing off of VO-52 :-)

As I see it, there is good news and bad news in this. For years, the
bad news was that rides to space have become so commercialized that
'we' can't get freebies or ultra-cheapies anymore, and we simply can't
afford to pay the proper price.
The good news, only recently, is that this commercialization is
starting to provide full-cost opportunities that might be within our
financial range. But these would require us to perfect many aspects of
cubesat-level miniaturization, and would require much more advanced
ground stations.
Of course, if some inexpensive opportunity arises, the AMSAT-DL P3E
satellite is available.

Yes.
AO-24 was in a low inclination orbit. Probably a transfer orbit inclination
of 2 -5 degrees. I recall the transponder output was up near 2450MHz.
It was very high and had excellent coverage. I believe it failed because it
went into a planned shutdown due to something like eclipse or temp etc.
Unfortunately it never switched back on.
While it was there it was very good. A bit low in the sky if you lived
above or below 60N or 60S but nice and easy to track. Like AO-40 it was always
in the southern sky from here.
When we talk about 10 million to launch it's worth remembering that the
approach that has shrunk usable satellites to 1-3U cubesats can also be
applied to MEO or GTO / HEO sats. Arianespace may no longer be flying test
flights, but Falcon 9 will go to GTO (and needs to be tested) as will the new
Indian launcher. There are new satellites going en-mass to 20,000km too. A
ride share with Galileo etc may be just as good.
Thanks

Hi Mark,
But the cost for a 3U CubeSat to GTO might just be feasable. Trouble is the
path loss with simple omni antennas, although the path loss would be
considerably lower if we used bands like 50 and 29MHz.
Snag also is how do you generate enough solar power to get a decent amount
of RF output for something in HEO ? I reckon one of the great things about
AMSAT-NA's FOX project is that they are experimenting with foldout panels.
Never been done on a CubeSat so it's pioneering work. But that's what 1U
CubeSat's are great for, a chance to experiment with new ideas at what is in
Space Terms a very low cost.
Looks like we are going to need to devise new ways of getting more power and
functionality in smaller packages. FOX is a great step in that direction.

David,
In some ways, the CubeSat programs resemble the old "X Projects" that the US
did with aircraft. Instead of building from scratch the ultimate plane,
they built a series of test beds that were designed to do one thing very
well. Eventually, the lessons learned from each project were combined into
a single airframe. For us, the trick is to ALWAYS provide useful
communications along with whatever is being developed.

Let's not forget about the funcube dongle as a terrific economical
solution for receiving. And any decent FM transmitter can key CW,
no? Assuming someone already has a vhf/uhf rig, I can see getting qrv on
linear

Simple answer...FM rigs will tend to "chirp" as you key the mic line as
the VCO pulls onto frequency...crystal matrix FM radios such as the old
Standard will be T-9...
The purists will cry about the chirpy signal...but, most people who work
CW on satellites would relish a new operator/contact even if they were QLF.
That being said...I have works scores of stations with my own "chirpy"
signal and even have received some polite 599's back.

Which is why I was interested in AO-40, for all the same reasons.
However, since I had already invested in setting up an AO-40 station,
I might as well use it.

Well, sure no disagreement from me on that. But I would suggest a one
design fits all idea. Make a simple simple satellite design that
could be assembled in near mass production quantities, get them into
orbit whenver opportunities prsent themselves.

Well, instead of thinking HEO for the time being, one simple design
tossed up multiple times, on the same frequency pairs, to minimise
tracking efforts is the way to go.

You guys are making me all teary-eyed! I loved that bird, especially for
all the "challenges" it presented. Mike, I still have the 10 gHz
downconverter I built for that never-used mode :-(
My first contacts were on 05 May 2001: W1BFN, KB2WQM (now KB2M), W7ID,
N1JEZ, WL7BQM (first DX), and WC0Y--all in mode U/S. My last contact was
K5VAS on 22 Nov 2003 using mode L/S. Later that weekend I took down my
antennas to move to VK8. I took everything I needed to work AO-40 in
Australia, including an 18" DSS dish with a dual-band feed, but by the time
I moved and got into a penthouse apartment with a big deck looking north
(why do you think I had to find a top floor with that view?), AO-40 died.
If it hadn't been for the launch of Eagle (AO-51), I would have never been
able to use that L/S gear. I used it dozens of times to talk to myself on
AO-51 as it orbited over the Indian Ocean :-) I used to do the same thing
on ISS packet. From where I was located (Darwin, NT), there were no other
population centers within the footprint of the LEOs (not even Sydney, Perth,
Brisbane, or Singapore).

My first Oscar Station,,,
I do not remember if it was Oscar 6 or 7, but it was 1975, and we
listened to many passes on the ten meter downlink.
We got from a local ham, an old AM vfo controlled 2 meter rig. It was
AM only. it had a Red face and was BIG like the size of a heathkit
SB-200 amp. two VFO's one for transmit and a separate one for receive.
anyway we connected out Hallicrafters TO Keyer to the PTT line of the
mic, (with no mic installed) and it worked amazingly well. That was
out Oscar station back then, we made like 25 states or so on that setup,

Hi All,
> You guys are making me all teary-eyed! I loved that bird, especially for
all the "challenges" it presented.
Ughh.. this really hit's me hard and I'm getting very sentimental
reading all email's to this topic.
But it gives me also
The launch campaign in french Guiana, were I was staying in Kourou for
more than quarter of the year, and the re-birth of AO-40 on Christmas
were the most exciting days in my life.
I haven't made many contacts, I was more among the "listeners" and
enjoyed the fun.
It's sometimes very frustrating to me that 10 years after the launch of
AO-40 we still haven't got P3-E into orbit.
We have been going to many up's and down's during this time, but we are
not giving up.
There are new challenges we are working on presently and some of them
give us a good hope of success.
Indeed and I'm sorry for that, It has been very quiet about the progress
of P3-E in the last year.
While most mechanical work is done, there was also progress on the
electronics, mostly the IHU.
However, one of the biggest challenges is indeed funding and a launch we
can afford.
That's where we a concentrating most of our efforts and time at the moment
Indeed, we need the support of the community. There will only a P3-E, if
we all really want it..
If you want to support P3-E, than please visit

the project - THANKS!

Hi Gang,
The Orlando Hamcation is just a week away, and AMSAT will be there in
force. We have a forum scheduled Saturday from 1:45 to 3:15, and this
year it is INSIDE! I expect
ARISSat-1 will be the main topic of discussion. We'll have live
satellite demonstrations, ranging from simple handheld/portable
operations, to fully automated systems. The ARISSat-1 engineering model
will be on display, and on the air. I'll have a FUNcube Dongle Pro on
display and in use. I'm also planning on having materials on hand for
new members to build their own CJU 435 MHz antenna, for free as
incentive to join and support AMSAT.
To make this all happen, we need your help. Orlando has become AMSAT's
busiest hamfest behind Dayton, and we need current members to assist in
the booth. If you can help answer questions and talk up the amateur
satellite program, please consider putting in a few hours behind the
table. Drop me an email at ko4ma@xxxxx.xxxx and let me know when you can
come by and help out!
73, Drew KO4MA

Boy, that sounds familiar !
My first Oscar station was a Regency HR-2B FM rig
with ONE crystal in the middle of the uplink band on 2 meters,
keying the high-low power switch. You couldn't hear the low
power but the 15 watts on high power made it fine.
And the receivers were an HW-101 and Hallicrafters SX-117.
Bought an AMECO preamp for HF, which helped out on 10 meters.
That was good enough to work lots of stations, maybe a total of
600 QSO's on OScar 6 and 7!
Then when the RS-10, 11 came along, I tried some mobile work
using an ICOM 230, again only one frequency, keying the PTT line,
no chirp, and Yaesu FT-301 for receiver. Larson 2 meter antenna and
Hustler 10 meter antenna on the pickup. Worked quite a few QSO's
that way, too!
All CW only, of course on mode A. Didn't get an all-mode rig
until about 1986 during the "RS" era.
73,
John
