Hi Clint, K6LCS
No !..... Using a 100 W tranceiver like a TS-2000 and a simple antenna
system you can work VO-52 as yesterday I did with IW6OVD

Sorry our QSO is in Italian but it last 12 minutes of chatting like on the

Subject: [amsat-bb] AO-51 end of mission
It is with a heavy heart I report that AO-51 has ceased transmission and is
not responding to commands. The last telemetry data indicated that the third
of six batteries was approaching failure to short, and observations indicate
the voltage from three cells is insufficient to power the UHF transmitters.
The IHU may continue to be operative. Initial tests with the S band
transmitter were also not positive, although more attempts are in order. We
have tried leaving the satellite in an expected state where if voltages
climb high enough, the 435.150 transmitter may possibly be heard.
The command team will regularly attempt communications with the satellite
over the coming months (and years). There is always the possibility that a
cell will open and we could once again talk to our friend while illuminated.
Thanks to all who helped fund, design, build, launch, command, and operate
AO-51. It's 7 year mission has been extraordinary. Please support AMSAT's
Fox-1 project, and other AMSAT projects worldwide with your time and money.
For the AO-51 Command Team,

Hmm, unlikely I would say:
A typical WX ballon goes up to about 30 km, maybe 50 km if you get a high
performance one. The AO-51 orbit is at about 750 km.
I witnessed the X2 (Spaceship one) launch in 2004. The rocket for the
orbiter fired at about 15 km (from the carrier plane)? and burned for 90
seconds just to reach 100 km.
This is *a lot* of energy which needs to be invested into the object. Now we
are talking 750 km, not 100, and then you still need to do a controlled
orbit injection burn. I admin, we are talking 10 kg payload, not 200 kg, but
doing this with a single stage booster launched from an unstable wx balloon
would be quite a challenge IMHO.
Not sure if that already happened, but did somebody ever talk to the
Europeans ? The ariane V is the most powerful, most reliable launch vehicle
today. They launch commercial satellites more or less once a month. I wonder
if they would donate a <10 kg payload every once in a while ??

OK.. a LARGE "punkin' chunker" or two really tall and flexible trees for a
slingshot...
More seriously, it seems that for anything of reasonable size to be launched,
particularly into an orbit that we rapidly enter not only the perview of
costly specialization but also of military / government permissions, etc.,
probably? much more delicate than ITAR considerations.
Please enlighten me if indeed there might be a way to get something up (and to
stay up) more economically.
Would there be any feasiblity to an initial "launch" by using high-altitude
weather ballons and THEN firing a small booster with appropriate guidance and
CCC (command, control, and communications) to steer it into an orbital
insertion? If the bird and booster weights were small enough, could a wx
balloon lift them adequately?
Just wondering...

The big Tampa Bay Hamfest is this weekend in Palmetto, and AMSAT will have a
booth, forum, and demonstrations of working satellites. I invite you to come
by on Saturday and learn about Fox and ARISSat-1, and just have a good time.
As always, I need a few members that are willing to help in the booth, in
particular during the forum on Saturday at 10AM, and during demonstrations
while I'm outside. Please drop me an email if you think you can attend and
help out for a bit. No experience necessary.

Since you asked..... :-)
With all my personal calls, I have logged a total of 10931 satellite
QSOs. Of those, 4891 (44.7%) were on AO-51's different
configurations, made from locations across the continental USA
as well as from Canada and Mexico. Since July 2010, I have logged
2233 satellite QSOs, with 574 of those (25.7%) on AO-51. My last
AO-51 QSOs were logged on 13 November.
As others have said, AO-51 was the satellite that brought me into
this part of our hobby. I had been a member of AMSAT for a few
years before then, worked a couple of stations on SO-35 in 2000
and a QSO on UO-14 in 2003, and even pitched in a little $$$ to
help toward the AO-51 launch fundraising campaign in 2004.
Once I started on AO-51, I tried SO-50 and AO-27, the ISS
cross-band repeater when it was active, and then on to SSB
and CW via satellite. And it's still fun....... :-)
> Looking forward to Fox-1(and siblings...) !!
Yes! As we continue using other satellites that remain operational,
here's hoping we are able to use the Fox satellites and those from
other AMSAT groups in the near future.

OK, I can?t hold a candle to Patrick's numbers, But in one of those ironic
twists, all my sat ops fall into the "Bonus Time". Here are my AO-51 stats:
First Sat QSO: 21 July 10 0100UT: W6AJP
Last AO-51 QSO: 30 Sep 11 2258UT: KA6SIP
165 QSO's
Most Worked Stations:

There is even a more simple solution just use what it is already installed
aboard ISS a cross band repeater and a lot of other piece of
amateur radio equipment.
And for the next satellite a fail safe system who can run the satellite when
batteries are depleted EG: something very basic who can run
when the satellite is in the Sun.

Well, a bit of physics here. To get from the Earth's surface to LEO
requires 10 km/S of delta-V. Even if you could get a payload to
orbital altitude by some hypothetical means, you would still need to
add 7.5km/S delta-V to bring it up to orbital velocity. From 30km
(typical high altitude balloon), the requirement would be somewhere
in between 7.5 and 10 km/S, which still means a considerable amount
of fuel required.

I suspect the rocket would still be very heavy.

There is also SO-50, which is still working. It takes a little more to hear
its 250mW compared to AO-27 and (previously) AO-51, but it still works.
Too many times in the past, SO-50 passes would be relatively quiet
with few stations on compared to the busy passes on AO-27 and
AO-51. With the unfortunate situation AO-51 is now in, maybe there
will be an increase in activity on SO-50.

That was correct, but there doesn't appear to be any new info on
that front at the AMSAT SA web site http://www.amsatsa.org.za/ :-(
Maybe one of our South African friends will be able to update us
on the status of that satellite.
73!

You know, from 50km up you can see a fair chunk of the earth. While it
might not be as cool as flying a satellite, a balloon-lofted repeater
could be quite good fun. What next, though? Well, maybe a UAV-lofted
repeater. I wonder how well a combination of a balloon for the heavy
lifting with a UAV-based payload for station-keeping would work?

If I may, in name of the Amateur Radio Satellite followers here in Puerto
Rico, say thanks for the team and their efforts for maintaining as long as
possible the operation of ECHO, nice little satellite which you know was on
AOS by the fading of the noise.
With it I could work from Brazil up to Canada withh all the limitations of a
mountain to my north, even worked Drew on his Caribbean ventures. Field
Days, JOTAS, special events and all, it gave us the taste to work fellow
hams and different grids. And, I rarely used more than 1/2 watt for the QSO's.

Made my first satellite contacts?to K4DLG (SK), KD8CAO and N3TL?in Oct of
2008 on AO-51.? I have now logged?6007 contacts with 56.97% on AO-51, 28.9%
on AO-27, 10.4% on SO-50.. the balance on HO-68, SO-67 and ISS.???What a
blast!
?
If you can't find me ... I am probably outside trying to make a contact ...
?

I believe there are problems with maintaining a High Altitude Platform in
position above 25 km.
Current research is based on platforms between 17 and 22 km high. At that
height they could provide coverage over a radius of up to 500 km.
In the UK we have the drawback that aeronautical amateur radio systems are
not permitted by our regulator.
