Yes, Dire Wolf runs on Windows. My doppler correction is with homebrew
software. SatPC or the others ought to work, I'd think.

Subject: [amsat-bb] Falconsat3 ASTARS Network Concept
Message-ID: <f4b1eaeb6db4e0b4fade85cc3b42bebc@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset="UTF-8"
Falconsat3 brings back a great satellite capability for emergency response
traffic into and out of remote disaster areas.
Its file store and forward BBS using the PACSAT protocol is ideal for
getting multiline messages, and pictures and data out of an area. Amateur
radio Sateliltes sort of abandoned this concept with the rise of the
internet. And then the short, real-time contact capability of APRS better
matched the shorter attention span of the evolving users.
But now we have both in Falconsat3. But we also now have the Internet and
can integrate a worldwide collection of satstations capturing all the
downlink PACSAT BBS packets and building a WEB portal on the ground that
always mirrors the traffic on the bird. Imagine that a remote operator can
post a photo or file that can be read on a Falconsat WEB portal by FEMA or
emergency operators back here anytime, anywhere.
The concept is suggested on this page: http://aprs.org/PFS3.html
All we need is someone to write the internet server that collects the BBS
packets from all the ground stations like the APRS-IS already does for
APRS, but this new PACSAT-IS would be just for PACSAT BBS traffic.
Then someone to collect the data and write the WEB Portal.
Then people to put up satgates (hopefully using omni antennas) and with
enough stations, all packets could be collected.
Anyway, I created the above web page to kind of serve as a target for this
exciting new Amateur Radio capability.
So even stations that are using OMNI antennas now and only decoding a few
packets per pass, we need to understand how well this works for high
elevation passes. Even this sparse data is good data.
Remember, with a standard TNC all you are seeing are the few UI packets in
the downlink. I think if you set KISS mode, you will be flooded with all
the streaming BBS data too. This continuous stream at 9600 can make it
easy to see the effect of an antenna in very short time.

Message-ID: <EB01349AB209413DB9863679AD8B57A1@xxx>
Content-Type: text/plain; charset="iso-8859-1"
An International Space Station school contact has been planned with
participants at Fleet Science Center, BE WISE Program in San Diego, CA, on
14 Oct. The event is scheduled to begin at approximately 18:26 UTC. The
duration of the contact is approximately 9 minutes and 30 seconds. The
contact will be direct between NA1SS and KJ6KDZ. The contact should be
audible over the state of California and adjacent areas. Interested parties
are invited to listen in on the 145.80 MHz downlink. The contact is expected
to be conducted in English.
The Fleet Science Center connects people of all ages to the possibilities
and power of science to create a better future. Established in 1973, it was
the first science museum to combine interactive science exhibits with a
planetarium and an IMAX Dome (OMNIMAX) theater, setting the standard that
most major science museums follow today. The Fleet is home to many programs
that engage girls in science, one of them is BE WiSE (Better Education for
Women in Science and Engineering). BE WiSE BE WiSE engages young women in
science, technology, engineering and math (STEM) learning experiences in
collaboration with the region's research, industry and academic
institutions. BE WiSE goals are to: stimulate young women's interest in STEM
through interactions with professionals, increase participants'
opportunities and knowledge of STEM fields of study, develop a community of
young women (grades 7-12) engaged in science learning through out-of-school
activities, and sustain interest and involvemen
t through alumnae and ongoing participation for women in science at all
levels. BE WiSE selects girls from all across San Diego County and has
sustained contact with over five hundred girls over the past 14 years.
Participants will ask as many of the following questions as time allows:
1. How does being on board the ISS for long periods of time affect your
overall health?
2. When deciding to be an astronaut, did you have any doubts? If so, how did
you overcome them?
3. What is the most interesting experiment you are doing on the ISS right
now?
4. Have you ever dealt with malfunctions on board the ISS? If so, how did you
solve it?
5. What do you like most about the ISS?
6. Is it hard to sleep? What do you dream about?
7. If you get sick on the ISS how do you receive treatment?
8. What does weightlessness feel like?
9. What is a typical day like for you?
10. Do you miss "real" food? What kinds of food do you like on the ISS?
11. Do you get heartburn/acid reflux? How do you deal with that?
12. What is the most interesting thing you have seen aboard the ISS?
13. How much does microgravity affect the experiments that you conduct on the
ISS?
14. What does the orbital sunrise look like?
15. What kind of medical testing do you go through before/after being in
space?
16. Are they currently working on lighter, more flexible space suits?
17. Do scientists from different countries collaborate on projects? If so,
what kind?
18. How much time do you spend practicing in zero gravity before going into
space?
19. How do you think private space travel will affect the ISS?

Sorry Bob,
With all due respect, but I could not disagree more with your
statement: "Falconsat3
brings back a great satellite capability for emergency response traffic
into and out of remote disaster areas. Its file store and forward BBS using
the PACSAT protocol is ideal for getting multiline messages, and pictures
and data out of an area."
Here is why:
1. Its foot print and availability is severely limited by its inclination
of 35 degrees. Most of the northern hemisphere has a few minutes and
low horizon activity during a very short window.
2. Any satellite that is not available 24/7 (e.g. geostationary) is not
useful for emergency operations. Having it around for a few minutes a day
does not cut it. There is a reason why folks use HF and VHF radios (and not
amateur radio satellites)
3. The equipment, software and user training is not there. Just look at the
"fun" people having getting the TX side going.
4. You can count on one hand the folks that are currently having RX and TX
ability to get a few packets through not even thinking about images etc.
5. Emergency response requires KISS equipment and training on the amateur
radio side.
On the other hand, it is a fun satellite to play with and like most APRS
satellites a niche to explore and enjoyable from a hobby perspective.
Again, these comments are within the spirit of our common interests
and acknowledging all the great work you are doing and have done.

But most hurricane disasters seem to be occurring well below that latitude.
In fact, the lower inclination is a bonus for the coverage area needing it
most.

Might try mentioning that to the people who took days to get a message out
or HF operators.

But when only 1 second packet burst is needed, then a few minutes is plenty
of time

But an APRS HT is small, compact, fits in the pocket, and can get the
message out ANYWHERE via APRS satellite a few times a day.

We learn. Getting a one-line message out by APRS satellite is to change
the FREQ from 144.39 terrestrial to 145.825 for space. Done. Most APRS
sats even respond to the same WIDE path as used terrestrially. Falconsat
needs three more steps. Change to 9600 baud and change the path to PFS3 and
freq to 145.84

Everything starts small. First pictures of my granddaughter were the size
of a lima bean.

Yes, wont that be fun... and all we need are a few satgates...

Amen there!

Amen! I really look forward to retiring some day and REALLY starting to

Falconsat3 brings back a great satellite capability for emergency response
traffic into and out of remote disaster areas.
Its file store and forward BBS using the PACSAT protocol is ideal for
getting multiline messages, and pictures and data out of an area. Amateur
radio Sateliltes sort of abandoned this concept with the rise of the
internet. And then the short, real-time contact capability of APRS better
matched the shorter attention span of the evolving users.
But now we have both in Falconsat3. But we also now have the Internet and
can integrate a worldwide collection of satstations capturing all the
downlink PACSAT BBS packets and building a WEB portal on the ground that
always mirrors the traffic on the bird. Imagine that a remote operator can
post a photo or file that can be read on a Falconsat WEB portal by FEMA or
emergency operators back here anytime, anywhere.
The concept is suggested on this page: http://aprs.org/PFS3.html
All we need is someone to write the internet server that collects the BBS
packets from all the ground stations like the APRS-IS already does for
APRS, but this new PACSAT-IS would be just for PACSAT BBS traffic.
Then someone to collect the data and write the WEB Portal.
Then people to put up satgates (hopefully using omni antennas) and with
enough stations, all packets could be collected.
Anyway, I created the above web page to kind of serve as a target for this
exciting new Amateur Radio capability.
So even stations that are using OMNI antennas now and only decoding a few
packets per pass, we need to understand how well this works for high
elevation passes. Even this sparse data is good data.
Remember, with a standard TNC all you are seeing are the few UI packets in
the downlink. I think if you set KISS mode, you will be flooded with all
the streaming BBS data too. This continuous stream at 9600 can make it
easy to see the effect of an antenna in very short time.

That honestly sounds like a really good advertisement for one of the Phase
4 satellite concepts if I've heard of one. Although I do kind of hope I can
get time to listen to the falcon sat before the symposium.

FIRST:
Did you perform the calibration proceedure in the G-5500 manual?
SECOND:
Did you go throught the calibration proceedure outlined with the tracker?
Satpc32 needs to be told explicitly (on the rotator setup page) that
the rotator is 180 degree capable.
