Passing along some sad news.  Al was very active on satellites at one point,
as well as meteor scatter, and EME.

RIP my friend.

NASA INVITES STUDENTS TO NAME MOON-BOUND SPACECRAFT



WASHINGTON -- NASA has a class assignment for U.S. students: help the
agency give the twin spacecraft headed to orbit around the moon new
names.

The naming contest is open to students in kindergarten through 12th
grade at schools in the United States. Entries must be submitted by
teachers using an online entry form. Length of submissions can range
from a short paragraph to a 500-word essay. The entry deadline is
Nov. 11.

NASA's solar-powered Gravity Recovery And Interior Laboratory
(GRAIL)-A and GRAIL-B spacecraft lifted off from Cape Canaveral Air
Force Station, Fla. on Sept. 10 to begin a three-and-a-half-month
journey to the moon. GRAIL will create a gravity map of the moon
using two spacecraft that orbit at very precise distances. The
mission will enable scientists to learn about the moon's internal
structure and composition, and give scientists a better understanding
of its origin. Accurate knowledge of the moon's gravity also could be
used to help choose future landing sites.

"A NASA mission to the moon is one of the reasons why I am a scientist
today," said GRAIL Principal Investigator Maria Zuber from the
Massachusetts Institute of Technology (MIT) in Cambridge. "My hope is
that GRAIL motivates young people today towards careers in science,
math and technology. Getting involved with naming our two GRAIL
spacecraft could inspire their interest not only in space exploration
but in the sciences, and that's a good thing."

Zuber and former astronaut Sally Ride of Sally Ride Science in San
Diego will chair the final round of judging. Sally Ride Science is
the lead for GRAIL's MoonKAM program, which enables students to task
cameras aboard the two GRAIL spacecraft to take close-up views of the
lunar surface.

NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the
GRAIL mission. GRAIL is part of the Discovery Program managed at
NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed
Martin Space Systems in Denver built the spacecraft.

Ah yes .. those early morning 5 am passes :). Been there, done that. I
guess what I meant by mentioning the other stations who don't care for
that grid is that it doesn't make it easier. There are many things, one
other being regular ops trying to work 10 or more contacts per pass
without giving others a chance. I usually sit back after 3 or so and
just listen if somebody is calling me.

Hey I just checked. We worked on FO-29 :). But I know what you mean. I
have a TS-2000 sitting here just for satellite stuff and it doesn't get
used as much as I would like which sometimes makes me question the
investment. But as soon as I had another nice QSO on VO-52 or FO-29
(AO-7 seems to be a challenge with my ant setup) all is forgotten and I
know why I bought it. And AO-51 is the only FM bird I use at the moment
given that birdie problem on SO-50 and AO-27.

I hear ya. But isn't it up to us then to promote the idea that one QSO
per pass is ok and not lost opportunity?

Agreed. Now the question again becomes as to why. Is it because there is
so much information out there that tells people all they need is a HT
and an Arrow antenna and off they go, or should we indeed focus more on
operating practice on top of that?
Fact of the matter is, at times it is not bearable and I simply turn the
radio off when the situation on an FM bird get too much out of hand.

I have never had any issues.  I like it because it is cross platform, only
one thing to keep current on.

But;

Easy to install? Yep

Easy to enter current location?  Fairly easy, though not obvious for everyone.

Painless Keplerian data updates - and able to choose WHICH Kep data you want

Hi all,

I just bought a Yaesu 736 and am interested in doing some work on the
satellites with SatPC. Can you tell me what most people use to connect the
736 to a USB port to do CAT control? I know there's an issue with TTL levels
and I also know not to use the prolific chip set.



Thanks!

Hi Bill and Dinesh,

I was a part of the ISRO team that conducted the Thermal Vacuum,
vibration and other environmental tests for both Jugnu and SRMSat.

I was able to receive the signals from both the satellites, while they
were here in my cetre during the above mentioned test. I even used
Funcube Dongle to receive and decode the telemetry CW data.

Frequencies:

SRMSat: Payload down link and CW Beacon on the same frequency -
437.425 (10dbm)
Jugnu:  CW Beacon - 437.275 (17dbm)
         Pay load  - 437.505

Mike,

     I find myself calling in the pile on HF on occasion (I'm working on
helping my HF signal this week).  Getting through on satellite is much
easier and faster.  Back when we had AO-13 and AO-10 we also had AO-21 (FM
Bird).  The FM bird was pretty much the same in those days.  You are correct
it is a lot like contesting.  I actually enjoy the quick exchange format of
the FM birds.  I really don't understand why other folks feel the need to
complain about it-- if you like it join us -- if it's not your cup of tea,
there are many other facets of Ham radio available.

73,
Joe kk0sd

Hi,

While I do agree with the below, one thing we should keep in mind though is
that there's a difference
between a pile-up on HF and on an FM sat. Not everybody on the sat may be
actually interested in
working that particular station so we also have to give those some room (in
that 10 minute pass). On
HF the time it takes to work the pile-up is usually a lot longer than that.

One thing I'd be interested to explore though would be how many of the folks
that work the FM sats
regularly actually do work DX on HF and often find themselves in a pile-up
trying to get through
quick and clean. This is out of pure interest and may help make it easier
for some.

The other problem is that before the madness starts, there are always other
stations already working
contacts before the "rare grid" station comes into the footprint.

Of course the best solution would be to get on the linear birds, we all win
the lottery so that we can launch
another Phase III sat or two and it would'nt be a problem anymore. (Ok, ok
.. just teasing).

I find myself calling in the pile on HF on occasion (I'm working on
helping my HF signal this week). Getting through on satellite is much
easier and faster. Back when we had AO-13 and AO-10 we also had AO-21 (FM
Bird). The FM bird was pretty much the same in those days. You are correct
it is a lot like contesting. I actually enjoy the quick exchange format of
the FM birds. I really don't understand why other folks feel the need to
complain about it-- if you like it join us -- if it's not your cup of tea,
there are many other facets of Ham radio available.

Content-Type: text/plain; charset="us-ascii"

According to the Explorer-1 Prime operations web page at

http://ssel.montana.edu/e1p/operations/

the satellite will transmit a 2200 Hertz tracking tone before each FSK AX.25
packet is transmitted.

What is the duration of the tracking tone? one second? ten seconds?

Does anyone have a sample recordings of the tracking tone and beacon?

>> ... I don't think much of "education" as a reason for hamsats ...

I am a school tech support volunteer for NASA and the ARISS program. I am
glad to see that we received more than 100 applications for five slots for
ISS contacts the first part of next year. That means there are more than 100
principals and more than 200 teachers who are exposing their thousands of
students to this aspect of amateur radio. An upcoming ARISS contact in San
Diego alone will have 480 students and 40 educators in the room.

And there are many educators "using" and including the FM LEOs and related
topics in their lesson plans.

>> ... It had some value a few decades ago but much less now with an
internet where kids can surf far more interesting information then whatever
ham radio has to offer ...

I hear this "The Internet is killing amateur radio ... " allegation all over
the place. Never any facts or evidence is ever offered ... a great teacher
can stimulate a classroom ,,,

>> ... I was President of a local school board ... and while educators would
take space station contacts because that is what they do...the educational
value was rated as low...and I think it is ...

Wow ... Why would a similar district have wonderful lesson plans and get
excited about this technology for their students - while yours found it
boring?

>> ... Really there is "nothing" unique about talking to the astronauts on
ISS using ham radio either directly or through a telebridge ...

We're really on opposite sides here. You cannot tell that to the 600+
audiences of assembled kids that have participated in the ARISS contacts.
Pick out ANY YouTube video of an ARISS project - and you will see joy on
faces ... that suppressed excited applause when the ISS astronaut first
responds ... and wild applause after the last transmission.  I find it
difficult to believe that a quality educator could make that experience
boring and ordinary.

>> ... Why is AMSAT floundering? Easy answer...they have no product that
interest people with large investments in amateur satellite gear ...

I didn't realize AMSAT was "floundering." But put that aside - No, we don't
have a new HEO bird on HF for you. As soon as AMSAT can raise about US$550K
for one, you can fire up your sat gear again. But there's a value in the
LEOs - I have been invited to show 'em off more than 20 times each of the
past four years to clubs and hamfests. There IS an interest in working the
LEOs.

>> ... and what they do they have proven functionally incompetent at ...

I am just sitting here and smiling, knowing that AMSAT's "incompetent
engineers" have AO-51 up and running at almost 900mW for us - that's with
one dead battery cell, and another at about 0.1V ... running past its
expected life expectancy.

>> ... I should give them a pass on Suitsat2 because they dont have a clue
about how to deal with the Russians...well thats more incompetence.

>From what I researched on my own (as I am not on the ARISSat-1 team in any
manner), I saw broken promises and unannounced/unexpected changes in
scheduling/testing/deployment - hardly anything you could blame AMSAT for.

But excuse me - I have another "Request for NASA Surveys" from another ARISS
school contact that I need to send to NASA this evening ...

And so it goes.

Hi Bill,

The ground station paper was written before the frequencies were
coordinated by IARU. As mentioned by Mr. Mani the downlink frequency
is 437.425 Mhz.

Apparently the srmsat website is down for the past couple of months.
The web-team is trying to get the website operational.

Hi Bill and Dinesh,

I was a part of the ISRO team that conducted the Thermal Vacuum,
vibration and other environmental tests for both Jugnu and SRMSat.

I was able to receive the signals from both the satellites, while they
were here in my cetre during the above mentioned test. I even used
Funcube Dongle to receive and decode the telemetry CW data.

Frequencies:

SRMSat: Payload down link and CW Beacon on the same frequency -
437.425 (10dbm)
Jugnu:  CW Beacon - 437.275 (17dbm)
         Pay load  - 437.505
