Hi Robert, WB5MZO
P3-A the first HEO built by AMSAT-DL and AMSAT-NA was similar to
OSCAR-10 but it was lost in the atlantic ocean with the main satellite
called "Firewheel" and another small satellite called Subsat because a pump
of fuel of the first stage of the ARIANE 1 flight L-02 failed and the 23
may 1980 was a black day for all of us but I don't remember if P3-A had an
insurance policy or not.
Peter DB2OS should have this information.

Peter I am pretty sure it was not Oscar 10 but the launch before it...AS I
recall Phase3A was launched with a spacecraft called "firefly"...and one
more which I dont remember (AMPTE?)and of course all three were lost..
But I agree now days the money is absurd.
Sure wish we had Oscar 10 back...

Ken:
http://oscar.dcarr.org is a good place to look for up to date reports
on types of ISS activity (when it is active). Another place to look is
http://www.ariss.net which indicates that (outside of school contacts)
the ISS TM-D700 digipeater has not been active for over a month.
The ISS digipeater was more active in the past - wonder why it is rarely
active these days.

Hi Bob, W7LRD
A F/D ratio of 0.375 is ideal for a feed VE4MA with two ports on N connectors
one RHCP and the other LHCP.
There is a set of 5 screws in une side of the tube to be adjusted for RHCP and
another set of 5 screws to the other side of the tube to be adjusted for LHCP
The screws are fitted longitudinally into a copper tube functioning as a
cilindrical wave guide with a cilindrical choke
fitted near the open end.
I have built it for 1296 MHz and it works great both for crosspolarization
circularity and VSWR
For detailed informations on a VE4MA feed for 1296 MHz look at the VE1ALQ site

Hello Domenico & all
Thanks for all the information. The measured F/D ratio works out to
0.375, therefore a patch would be appropriate. As mentioned earlier I would
be content to just be able to receive EME (for now). For transmitting no
doubt a different feed would be needed. Currently I am looking around for a
preamp. I built a dual helix feed I am going to use on a four foot primestar
off center dish. I used to receive on AO40 (sobsob) with a 3731AA
downconverter. This same system will be used for transmitting (L band) on our
next HEO. Maybe by planning and working toward the next HEO will generate
more intense drive by all concerned. I can mount the 70 watt amp behind the
12 foot TVRO as suggested. Could a short helix be used for receive on the big
dish? They are easier to build as opposed to a patch. All this work (fun)
will help fill the void untill the next HEO. Fr om what I am reading on the
BB I could be at this for a long time. Any additional information would be h!
elpfull, perhaps others can get something out of this. I have some pictures
of the dish, dual helix I can send upon request.

Hi Bob, W7LRD
Before to start anyting you must to know the F/D ratio of your dish
because this parameter will tell you if a patch as
a feed is suitable or not for it.
If your TVRO dish is a prime focus dish to measure the F/D ratio is very
easy
Put your dish horizontal on the ground looking up 90 degrees and strain a
rope passing just through the center of the mouth and measure the diameter D
Measure the depth of the dish just from the center of the mouth between
the rope and the bottom of the dish and call the deepth c
2
D
D
F/D = ----------------- and the focal point F = --------
------ from the bottom of the dish
16 x c
16 x c
If the F/D ratio is less than 0.5 then a patch can be used but if F/D is
greater then 0.5 then a patch is not suitable.
By the way a patch as a feed is not used at all for EME because there are
type of specialized feed that are much and much better.
If the F/D ratio is less of 0.5 then a VE4MA feed can be used and if the
F/D ratio is greater of 0,5 then a dual mode dish W2IMU must be used.
Both VE4MA and W2IMU are dual port feeds one the LHCP is used to transmit
and the other one the RHCP is used to receive.
Waiting for P3E and depending of the F/D ratio of a 5 meter dish that I
plan to build for 1296 MHz EME I have already built both a VE4MA and a W2IMU
feeds in order to be prepared for EME in the future because unfortunately the
future seems to be not bright for the HEO satellites.

Many thanks for the information from many of you. I realize I will need
a preamp. For now I will be content to see what I can hear. As you can guess
once I can copy signals I will want to join in. That will require at very
least mounting the amp at the antenna and a sequencer. I have seen W0LMD' web
site as well as several others. I want to start out slow, before I "lose it".

Jeff:
The url http://mangrove.findu.com/cgi-bin/pcsat.cgi shows (a probably
very limited view) of who has moved APRS packets through GO-32.
Looking at that site it seems that there is only one sat-gate in the
U.S. that monitors GO-32 and that is K3PDK who is located in Maryland so
don't expect to see a lot of reports of stateside GO-32 APRS activity.
I do occasionally hear other folks APRS packets being repeated by GO-32
and sometimes hear folk poking at the GO-32 pbbs.

Hi!
After months of trying to make a portable station that would
allow me to work the SSB/CW satellites (first with an FT-817ND
and AOR AR8200Mk2B wide-band receiver, then later with two
FT-817NDs, all using my Arrow Antennas handheld Yagi), I finally
made everything work. At 1756 and 1758 UTC today, I logged my
first two satellite QSOs not using FM on either the uplink or
downlink. As I expected, it was not an easy thing; FO-29's 2m
uplink seemed to make it a bit easier than a 70cm uplink like I
had tried before on VO-52 or AO-7. Now, after over 4100 satellite
QSOs in the last 2 1/2 years or so, I can say I've got at least a
couple SSB satellite QSOs to go with the others I've done on FM.
I know that computer control for either - or both - of the radios
is the preferred way to go. Less work for the operator, reducing
how much my signal moves through the passband due to Doppler, and
simply more time to work other stations. I will most likely end
up with a portable setup using a small laptop that can control
these two FT-817NDs or some other radio(s), eventually. I will
also rig up a tripod or something for the Yagi, or try another
antenna, so I don't have to hold it while trying to work the
radio(s). I decided that the 1745-1759 UTC FO-29 pass this
morning to my east would probably be a good pass to try. Good
elevation, and a footprint covering most of North America. I set
up my radios in the back of my truck just over the line into grid
DM44ha northeast of Phoenix AZ, and tried my luck.
It took a couple of minutes to get used to finding my signal in
the downlink. My 5W signal with the Yagi was more than enough.
I heard some CW early in the pass, then I could hear a couple of
voices - Joe K3SZH and Jeff K7WIN. When those two finished their
QSO, I quickly called K7WIN. K3SZH came back instead, and I made
a quick QSO with Joe. I followed that up with another quick QSO
with Jeff K7WIN. Both Joe and Jeff commented I had a good signal
through the satellite. Thanks for the QSOs, and especially for
dealing with my non-automated station near the end of the pass!
Now I can go back to working on VO-52 and AO-7, plus the new Delfi
satellite, and see if I can do the same with a non-FM satellite
using a 70cm uplink. And keep on working FO-29, a very nice bird.
I'm not turning my back on the FM birds, but adding more options
when I want to play radio via satellite. :-)

NanoSail-D/PRESat Update from
http://www.nasa.gov/mission_pages/smallsats/nanosaild.html
NASA's NanoSail-D and PRESat missions ended on Aug. 2, 2008, about two minutes
after launch, when the SpaceX Falcon 1 launch vehicle experienced a problem
during stage separation and was unable to achieve an Earth orbit.
Although we were not able to test our payloads in space, NASA mission managers
and payload engineers achieved success in these two low-cost missions by
rapidly pulling together expertise from across the agency to develop, build
and ground-test an innovative solar sail nanosatellite and a fundamental space
biology micro-laboratory. The communications team also successfully
established a fully operational South Pacific Ground Communication System
using two ground stations, which were transported and installed at Kwajalein
Atoll in the Marshall Islands and at the Universidad Centroamericana in El
Salvador. This mission provided an excellent opportunity for collaboration
between two NASA centers, other government agencies, academia and the
burgeoning space industry. Through the development of NanoSail-D and PRESat,
NASA gained experience and knowledge it can apply to future small and
nanosatellite missions.

On an SO-50 pass this evening i heard over pile up the distinct Pave Pawns
signal (braw braw braw) pulsing signal. I don't know if the
system is able to generate harmonics down to the 2 meter band? If it was not
pave Pawns it is something i heard on AO-40 and that was
triggering LEILA at that time?
Anyone else on that pass heard that?

-----------------------
I agree with Peter. And as a member of AMSAT-NA and a person that resides
in NA, I have said these statements publically many times. Actually, one of
my last postings addresses item #1 in your e-mail.
Also, it goes without saying that #2 is an imperitive. The only reason that
the ARISS team has been able to acquire 9 launches of hardware to ISS since
2000 is that the space agencies have a stake in our activities as it
supports getting students from 6 years old to college age interested in
science, technology and mathematice. They are willing to invest in these
flights because they see a benefit to them as well as society.
So I think this wisdom is shared worldwide.

Falcon-1 Launch Failure
AMSAT News Service Bulletin 223.01

BID: $ANS-223.01
SpaceX's Falcon-1 rocket lifted off from the Kwajalein atoll on 03
August 2008 at 0334 UTC. On board was the Trailblazer satellite for the
Jumpstart Program of the United States Department of Defense?s
Operationally Responsive Space Office (ORS). Also on board where two
triple-cubesats, PRESAT & NANOSAIL-D, from NASA which had beacons in the
amateur 70cm band.
Unfortunately, an anomaly occured approximately 2 minutes 20 seconds
into the flight. The engineers said the rocket stages did not separate
and the second stage did not ignite.
SpaceX has announced that the problem with the last launch was that
the first stage regenerative engine continued burning longer than they
expected. It therefore bumped into the second stage after separation.
A new downward looking video that includes this action is available
at:

HAM RADIO IN SPACE: THE PERSEID METEOR SHOWER ON AUGUST 12
Meteor scatter enthusiasts attention. The annual Perseid meteor shower
peaks on Tuesday, August 12th. The best time to see them and make
contact by bouncing signals off their ionized tails is during the dark
hours before dawn on Tuesday morning when forecasters expect 50 to 100
meteors per hour.
The source of the Perseids is Comet Swift-Tuttle, which has littered the
August portion of Earth's orbit with space dust. The dusty zone is broad
and Earth is already in its outskirts. As a result, even before the peak
on August 12th, you may see some "early Perseids" streaking across the
night sky. (VHF Reflector)

"Nanosputnik" Cubesat "Polar Lights"
AMSAT News Service Bulletin 223.03
From AMSAT HQ SILVER SPRING, MD.
Augugst 10, 2008
To All RADIO AMATEURS
BID: $ANS-223.03
I am asked by Alexander Zaitev RW3DZ of the Izmiran Institute, in
Troitsk outside Moscow, Russia, to publicise his proposed "Nanosputnik"
Cubesat "Polar Lights."
FYI the Izmiran Institute made the first spaceborne magnetometer, on
Sputnik-3 in 1958. It is at:
http://www.izmiran.ru
RW3DZ recently referred to the Nanosputnik Cubesat in a blog at:
http://www.vhfdx.ru/sputnikovaya-svyaz/50-let-kosmicheskoy-eryi
and on his website at
http://rk3dxb.narod.ru/polar_lights.html
He is establishing a team within the promotion of amateur radio to young
people around the RK3DKB club shack at Troitsk. John G7HIA and I were
welcomed there last Sunday.
The Nanosputnik is proposed to be built on a 10cm Cubesat frame and to
weigh 1 Kg. Command uplink will be in 2 metres and data downlink at
various data rates in 70cms, there are precise frequencies given but it
is probably unwise for me to give them out at this stage as the
satellite is not built yet and I do not know whether IARU frequency
coordination has been undertaken. There may be an experimental 5 GHz beacon.
The proposed payload is a unique magnetometer which will detect
fluctuations along the flux lines of the magnetosphere and will be
oriented along the flux lines within 1 degree by an on-board GLONASS/GPS.
Data sampling will be 1 observation/second and he is interested in
downloading every quarter orbit into the GENSO network.
There is also scope for a CCD camera and cosmic ray detector.
Orbital life is estimated as 3 years with rechargeable batteries and a
solar panel charging system.
I do not have any information about launch opportunities.
John G7HIA and I will continue to work with RW3DZ and will bring any
other information we have to this bb as we get it, although we are not
responsible for this Nanosputnik in any way whatsoever.

1. Upcoming School Contacts
Two simulated Amateur Radio on the International Space Station (ARISS)
contacts are scheduled for Tuesday, August 5 with U.S. deployed soldier
dependents visiting Euro Space Camp (ESC) in Belgium. These training
sessions are terrestrial-based amateur radio contacts using
ARISS-equivalent equipment. There will be EchoLink and IRLP coverage of
both contacts.
? The first simulated contact is scheduled with Koichi Wakata, KC5ZTA,
at approximately 14:20 UTC.
? The second simulated contact will take place with astronaut Soichi
Noguchi, KD5TVP, at approximately 14:50 UTC.
An Amateur Radio on the International Space Station (ARISS) contact has
been scheduled with Town of Berkeley Heights, New Jersey, Summer
Playground Camp on Wednesday, August 13 at 16:08 UTC. The New Providence
Amateur Radio Club has been involved with this camp for the last four
years. It has provided an introduction to ham radio on the air by
setting up HF and VHF stations and having the campers communicate with
hams around the world. The ARISS contact will be an extension of this
activity.
2. United Space School Contact Successful
An international group of high school students attending United Space
School in Seabrook, Texas experienced an Amateur Radio on the
International Space Station (ARISS) contact on Thursday, July 31.
Telebridge station ON4ISS in Belgium facilitated the contact. Twelve
students had16 questions answered by astronaut Greg Chamitoff, KD5PKZ.
The audio for this event was fed into the EchoLink AMSAT (101 377)
server, receiving 10 connections and it was also fed into the JK1ZRW
(277 208) server.
3. ARISS Meetings Held
The annual Amateur Radio on the International Space Station (ARISS) Face
to Face Meeting was held in Moscow on July 17-18. Status reports were
given by all committees and the election of officers was held. This
meeting was preceded by the first Amateur Radio Working Group (ARWG)
conference and was followed by a Technical Interchange Meeting (TIM) on
July 21-23 where discussions covered SuitSat-2 and ARISS hardware. A
final meeting was held at the Gagarin Cosmonauts Training Centre (GCTC)
to discuss astronaut training on the ARISS equipment. All meetings were
successful, much was accomplished and minutes will be available in the
near future.
4. NASA Posts ARISS Article to Web Site
An Amateur Radio on the International Space Station (ARISS) article has
been written and posted to NASA Web sites. Several ARISS members were
interviewed for the story, including astronaut Bill McArthur, KC5ACR.
?Communication From Space Inspires Young Minds? may be found at:
