BID: $ANS-135.01
The 2011 Dayton Hamvention will be held this year from May 20-22,
2011 and AMSAT will be there. The AMSAT theme for 2011 is "Providing
Education Through Amateur Satellites". We will have multiple exhibits
of the new AMSAT satellites on display.
You'll find AMSAT at the same spot (Booths 444-449) in the Ball Arena,
right across from the ARRL area and just inside the door from the Sat-
ellite Demonstration area. Plan to visit all of the AMSAT activities!
AMSAT has planned a number of great activities during the Hamvention.
Here is a sample of the events and activities planned for the entire
weekend. Links to all of these activities can be found on the AMSAT
web page: http://www.amsat.org.
This list has been updated since last week's bulletin!
+ Meet astronaut Doug Wheelock, KF5BOC Friday 1:30-2:30, Saturday,
3:00-4:00 at the AMSAT booth.
+ ARISSat-1 operational prototype will be on display.
o Tune your HT to 145.950 MHz to hear a preview of the FM downlink.
o Watch the demonstration of the ARISSatTLM software receive and
display the CW beacon and BPSK telemetry using G6LVB's FUNcube
Dongle.

satellite on display, resurrected by W1AW Station Manager Joe
Carcia, and ARRL Lab Test Engineer Bob Allison, WB1GCM. The CW
transmitter is tuned to 145.080 MHz. It will transmit at Part 15
levels with only 10 microwatts of power across a 50 ohm dummy load.
A satellite transceiver will be positioned next to the unit that
will be used to receive the CW signal. You will hear it transmit
"HI HI," just as it did 50 years ago.
+ The fifth annual AMSAT/TAPR Banquet will be Friday night May 20.

Dave Taylor, W8AAS reported a very successful AMSAT presence at Space
Day 2011 held at the Smithsonian National Air and Space Museum on the
Mall in Washington DC on May 7. According to the ARISS status report,
the average crowd in the Museum on this Saturday in May is about
30,000.
Featured displays included prototype picosats, cubesats, space hard-
ware including laser reflectors for the kids to try out. A crowd of
250 people watched the ARISS contact as six youngsters asked questions.
Each one had three questions to ask and we got through all of them with
time to thank Cady Coleman, KC5ZTH, give her a round of applause, and
hear her response. Mark Steiner, K3MS handled the ARISS uplink/downlink
from NASA Goddard amateur radio station K6DUE.
Prior to the contact, former Payload Specialist Greg Linteris spoke to
the crowd. Greg had trained with Cady for one of his flights. He was
also on one of the last SAREX missions (STS-94).
This year a group from Thomas Jefferson High School for Science and
Technology brought a working prototype of their Cubesat. They demon-
strated with the prototype how one can uplink a text message and their
Cubesat converts the text message to speech and transmits the speech on
the downlink. They are manifested on a SpaceX Falcon 9 launch for early
next year. Orbital Sciences has been providing them with assistance for
the project.
At Space Day a new version of the AMSAT-OSCAR slide show was run. A link
to a PDF version of the slide show has been added to the AMSAT web page.

AMSAT Director of Awards, Bruce Paige, KK5DO says, "It's that time
of year again: Summer and Field Day!"
Each year the American Radio Relay League (ARRL) sponsors Field
Day as an emergency preparedness exercise. The event takes place
during a 24-hour period on the fourth weekend of June. For 2011
the event takes place during a 27-hour period from 1800 UTC on
Saturday June 25, 2011 through 2100 UTC on Sunday June 26, 2011.
Those who set up prior to 1800 UTC on June 25 can operate only
24 hours.
The Radio Amateur Satellite Corporation (AMSAT) promotes its own
version of Field Day for operation via the amateur satellites,
held concurrently with the ARRL event.
Bruce advises, "If you are considering ONLY the FM voice satellites
like AMSAT-OSCAR 16, AMRAD-OSCAR-27, SaudiSat-Oscar-50, or AMSAT-
OSCAR-51 for your AMSAT Field Day focus. Don't, unless you are simply
hoping to make one contact for the ARRL rules bonus points."

The ARISSat-1 satellite was intended to be activated in April as
part of the 50th anniversary of Yuri Gagarin's famous flight.
However, no ground stations reported hearing the satellite. To
follow up, the ARISSat-1 team had a teleconference with represent-
atives of RSC-Energia (Russia) and NASA to request a clarification
of the events and discuss what happened.
According to RSC-Energia, the battery in ARISSat-1 was only charged
once on the ground and was then used for a variety of tests and dur-
ing the February activation event. It was not recharged prior to the
April Yuri Gagarin activity since it can only be charged a limited
number of times on the ISS.
The cosmonauts reported that they activated the satellite and con-
firmed that they heard the signal on the ham radio equipment on board
the ISS. Since the battery was nearly depyear.

modified Soyuz TMA for Lunar tourists" which follows below:
U.S. Space Adventures, the only company currently offering tourist
orbital spaceflights, has offered to equip the Russian Soyuz TMA
spaceship with additional living space for eight-day commercial
flights around the moon, the company said late on Thursday.
The firm announced on April 28 that it would offer moon orbit tourist
trips, albeit with a price tag of around $150 million per seat.
"After consultation with Rocket Space Corporation Energia (the Soyuz
TMA design authority), modifications to the Soyuz TMA configuration
have been agreed upon. The most important is the addition of a sec-
ond habitation module to the Soyuz TMA lunar complex," Space Adven-
tures said.
A moon tour mission would include separate launches of a Soyuz and
the upper stage, their docking in a low Earth orbit, a flight to
the moon with the upper stage engine, the separation of Soyuz from
the upper stage rocket, an orbit around the moon, return to Earth
and landing.
Space Adventures is currently selecting candidates for the next
space tour together with the Russian Federal Space Agency.
The company quoted Vice Chairman Richard Garriott as saying it
had sold one of the two seats for the flight and anticipated that
the launch would occur in 2015.
The CEO of Russia's Gagarin Research and Test Cosmonaut Training
Center Sergei Krikalyov has said the center was ready to train a
professional cosmonaut and a space tourist for the future flight.

Hello AMSAT-BB:
I have TH-D72A HT connected to a ANLI AL-800 34" telescoping whip.
This morning there was an almost 90 degree pass over my grid square
(FN20rk). I get loads of packets but for the life of me I can't
beacon myself! :-(
I have my Decay Algorithm off, I have beaconing every 30 seconds (I
even manually beacon by pressing F+[Beacon] as per the Kenwood
manual). I have my beaconing in APRS format.
Is this just not gonna happen on a HT? I have tried 4 times with no
luck (all high elevation passes). Again I see every packet that flies
by (comparing my HT list with that on ariss.net). Very frustrating.
Help!

I personally haven't tried to do APRS from an HT on the ISS. I used to get
a few lucky packets through PCSAT back when it was working well but up until
a couple of weeks ago I hadn't heard the ISS in packet mode in some time.
I'd say keep trying. Sometimes you'll get lucky and can get a packet
through. You may need to go with a yagi, though...
Good luck!

Well I hear a lot (it was a W->NW->N pass at a 21 degreeish max
elevation) but I can't seem to beacon myself.
I have set my PATH to Others/ARISS. I see some have used
ARISS,WIDEN-n but I don't see the need.
Is there anything else I have to do? My beacon is set again to TX 30
seconds AUTO. I constantly try a Quick Beacon with the TH-72A but I
can't really tell if it send it.
Also, to send a message via the ISS what is the address?
I have been using RS0ISS-4 based on packets received.
Any comments before 4:20EST would be appreciated as I have one more
really good high elevation pass then...

It has been a number of years (8 or so) since I have done
anything with Packet and ISS but one thing I never did was
try with a H/T. I always used my FT-847 with 10 watts
(or more) and always seem to make it.
It seem with as many in the US trying the same thing at the
same time you may as well try to get DXCC QRP. Not saying
it can't be done, but how much time you willing to put into it?
Or I'am missing something?
John, W0JAB

I just set UNPROTO CQ VIA ARISS. I've heard that the 'CQ' makes no
difference; it works with or without the CQ.

When you beacon at a fixed interval it likely does not take into account
whether the frequency is clear. You may or may not be colliding with the
dozens of other users blasting a UI packet upward. Since its an FM channel
the strongest signal arriving at the ISS captures their receiver. If you fit
in between the other packets 5 watts usually gets through nicely.
When I run with a hardware TNC I use CONVERS mode. I have a summary of the
hardware TNC commands at:
http://home.comcast.net/~k9jkm/ARISS_Packet_How_To/ ... but not sure how
those map into your HT's setup.
I also use AGWPE and UISS. The VIA [path] is selectable from a pulldown menu
from which I select ARISS.
> Also, to send a message via the ISS what is the address?
The ISS PBBS is RS0ISS-11. This requires a "hard connect" which is not
recommended because over populated areas you will never to able to complete
the QSO with all the other competing UI packets out there. RSOISS-11 is
single user and when connected the full AX.25 protocol kicks in with the
acks and retries, etc. We see ISS go over the horizon faithfully executing
channel protocol and you will have not have been able to upload your
greetings. Stations over the horizon will see the AX.25 disconnect message
as it times out from your CONNECT request.
The crew is rarely at the keyboard so UI digipeating is your most likely
path to success.
Stations in less populated parts of the world connect to the RS0ISS-11 PBBS.
It does not seem to work too well over the USA from my experience.
> I have been using RS0ISS-4 based on packets received.
VIA ARISS translates into RS0ISS-4 or RS0ISS-3 depending on the setup aboard
the ISS.
For the RF side I run 5 watts into a 3-element 2 meter beam. The beam is
fixed elevation around 20 degrees and turns on a TV rotor I got on ebay for
$9.

Alexander --
I have a TH-D7A and I don't know if the TH-72A works the same but
it's worth a try --
when I want to "force a beacon xmit now" -- (because I don't hear
anyone else transmitting) --
I press the BCON button (to turn it off) and then immediately press
it again (to turn it back on) --
the TH-D7A transmits the packet and then starts the interval timer up.
So yes, as the K9JKM pointed out - you have to listen for a "hole"
and then try sending a few in rapid succession.
It looks like there is an ISS-DATA entry on ==>
http://oscar.dcarr.org/index.php
so you can see if the digipeater is on.
How are you determining if you have been heard -- are you looking for
the indication on the TH72A ... or do you check
the site ==> http://www.ariss.net/
Don't give up!

I am a bit confused. What's the difference between:
"ARISS" vs "UNPROTO VIA ARISS"
Should they not both work?

It seems having an open squelch may cause the TNC to not transmit
because it things the line is busy.

Thank you very much. Question, it seems you are explicitly doing
packet radio and not APRS (a derivative).

I think when I select PATH, I am to put in a string, I would assume
ARISS and the my TNC will add the "VIA" part correct?
(which would answer my question above)

Again this is for full blown packet radio? I am just trying to use
the APRS messaging service.

Right, got it.

Alright, so I again should address the message to 'ARISS' and not an
explicit ISS address?
