In today's nasa.all file, HuskySat's name has a space in it: "HuskySat 1"
Spaces in satellite names can cause problems for some applications.
nasa.bare has it correct: "HuskySat-1"

Amateur Radio on the International Space Station?
?
Contact Opportunity?
?
Call for Proposals?
?
Upcoming Proposal Window is February 1, 2020 to March 31, 2020
?
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew member on board the ISS.? ARISS is happy to announce a proposal window
will open February 1, 2020 for contacts that would be held between January
1, 2021 and June 30, 2021. Crew scheduling and ISS orbits will determine the
exact contact dates. To maximize these radio contact opportunities, ARISS is
looking for organizations that will draw large numbers of participants and
integrate the contact into a well-developed education plan.?
?
The proposal window for contacts between January 1, 2021 and June 30, 2021
will open on February 1, 2020 and close on March 31, 2020.? Proposal
information and documents can be found at www.ariss.org. Two ARISS
Introductory Webinar sessions will be held on November 7, 2019. The first is
at 6:00 PM ET and the second is at 9:00 PM ET. The same material will be
covered during both sessions, so choose the session that best fits your
schedule. The Eventbrite link to sign up
is?https://ariss-introductory-webinar-fall-2019.eventbrite.com?.
?
The Opportunity?
?
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.?
?
An ARISS contact is a voice-only communication opportunity via Amateur Radio
between astronauts and cosmonauts aboard the space station and classrooms
and communities. ARISS contacts afford education audiences the opportunity
to learn firsthand from astronauts what it is like to live and work in space
and to learn about space research conducted on the ISS. Students also will
have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight
and the complexity of scheduling activities aboard the ISS, organizations
must demonstrate flexibility to accommodate changes in dates and times of
the radio contact.?
?
Amateur Radio organizations around the world with the support of NASA and
space agencies in Russia, Canada, Japan and Europe present educational
organizations with this opportunity. The ham radio organizations' volunteer
efforts provide the equipment and operational support to enable
communication between crew on the ISS and students around the world using
Amateur Radio.??

About ARISS:
?
Amateur Radio on the International Space Station (ARISS) is a cooperative
venture of international amateur radio societies and the space agencies that
support the International Space Station (ISS).? In the United States,
sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American
Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and
Space Administration (NASA). The primary goal of ARISS is to promote
exploration of science, technology, engineering, and mathematics (STEAM)
topics by organizing scheduled contacts via amateur radio between crew
members aboard the ISS and students in classrooms or public forms. Before
and during these radio contacts, students, educators, parents, and
communities learn about space, space technologies, and amateur radio. For
more information, see www.ariss.org.

Next week the name will be HuskySat-1.
For now go to www.amsat.org "Satellite Info", "TLE/Keplerian Element
Resources".
Download the "Bare elements" (nasabare.txt) and use "2019-071J" set of TLEs
for HuskySat-1.
The objects are still very close together so we just have to wait.

I did a google search on how I could better calibrate my el-cheapo SDR to
receive HuskySat-1 (I use NOAA weather stations to calibrate roughly to
VHF), and I found this article by WA1CYB:
https://www.amsat.org/wordpress/wp-content/uploads/2018/02/2017Symposium-SDR-F

Sure enough, Channel 17 had a strong pilot tone at 488.309441 for me to use
as a half-way decent reference! Hoping this can help others in the
future.

I'm not familiar with the program that is opening the archive. That seems
to be the program throwing the error. If you unpack it at the command line
does it work? The commands are:
gunzip FoxTelem_1.08y_linux_tar.ga
tar xvf FoxTelem_1.08y_linux.tar
That should create a folder will all of the files in. Run those and let us
know what error message they throw. The program you are running is almost
certainly just running those commands for you.

This is a bug fix release for FoxTelem to fix an issue with the IQ decoder
for PSK. If everything is working for you, then you do not need to
upgrade. This has been tested for a couple of days but has not had the
long regression testing that we usually do.
I'm releasing it now (quickly) because if you are using the internal SDR in
FoxTelem, in IQ mode, then this is a mandatory upgrade. It does not work
well with weak signals currently and this fixes that. It worked fine in
the lab, hi hi. It should now perform as well as a separate SDR. I
personally am still getting much better performance from my old FT736R and
others are getting good results with modern radios. But this raises the
performance of SDR based decodes.
http://amsat.us/FoxTelem/windows/
http://amsat.us/FoxTelem/linux/
http://amsat.us/FoxTelem/mac/
One thing worth considering. Doppler tracking works better than FindSignal
but you have to be using the latest keps and you need to consider exactly
what the downlink frequency needs to be set to for your situation. Note
that FoxTelem already offsets by 1.4kHz to put set the center of the PSK
signal in the sideband. You don't need to offset it. (You do if you are
using a seperate SDR and feeding the audio to FoxTelem).
If you are running in FindSignal mode (without keps) then the bit SNR level
at the bottom of the window is critical. For COSTAS it needs to be about
1.5 for Dot Prod it MUST be lower, say 0.5, Otherwise it will never lock
on.
Yea, lots of settings to get wrong. Have fun playing. Please send reports
and let me know how it works for you.

For those in other parts of the world with GSM networks kalibrate-rtl
can be an option to get to the same result.

Hi!
On my way to the Yuma Hamfest on Thursday, 13 February, I will visit
grid DM31 in the Organ Pipe Cactus National Monument in southern
Arizona. Depending on traffic leaving Phoenix and the weather, I hope
to be down there between 1430 and 1600 UTC. I plan on working passes
until it gets dark down there, which should be around 0100 UTC, as I
still need to be in Yuma that evening in advance of the hamfest. I
will work satellites in FM, SSB, and packet, depending on availability.
I will probably operate from the national monument's visitor center,
which is in grid DM31ow.
I will run APRS in my car using WD9EWK-9 for the drive, but APRS
coverage doesn't normally extend into the national monument and around
the USA/Mexico border in that area. You can follow my drive at:
http://aprs.fi/WD9EWK-9
I hope to be able to tweet updates from DM31, which would appear on my
@?????? Twitter account. For those who do not use Twitter, you can see
my tweets in a web browser at:
http://twitter.com/WD9EWK
QSOs from DM31 will be uploaded to Logbook of the World. QSL cards are
available on request - please e-mail me with the QSO details. No need
to first send me a QSL card and/or SASE. If you are in my log, I will
be happy to send a QSL card.
Thanks, and 73!

Hi folks,
Acknowledged that this is "not supported", but others appear to have had
some success using an RTL-SDR dongle under FoxTelem. With the launch of
Huskysat-1, I though I'd give it a try. I'm missing something, but
can't find any suggestions.
I have a Raspberry Pi 2B that I've been using as an RTL-SDR server,
connecting Gqrx to it over the home network. rtl_tcp is running there,
all just fine.
Tried firing up the latest FoxTelem, choosing RTL SDR as the source, but
the program says it can't find the dongle. "Insert the device or choose
an other source" when I hit Start. Shut down rtl_tcp, of course, so as
to not have a fight over access. Tried removing and inserting the
dongle. Still no joy.
I expect I'm missing some morsel of driver software or configuration to
connect FoxTelem to the RTL-SDR dongle, perhaps something similar to
rtl_tcp.
What am I missing?
Thanks,
Greg KO6TH

Noticed? today that huskysat stops sending data and sends only a carrier
for about a second then starts back up, saw it do that 4 times last pass.
DAC overflows?

Greg - I've had zero luck using the rtl-sdr dongle directly with FoxTelem.
I can get it to connect, at least - but it decodes almost nothing (it has
to be a super powerful signal to get anything). However, if I use the same
dongle, with GQRX audio piped into FoxTelem via pulse audio, then it works
wonderfully. Not sure why the difference is.
I will say that running the GQRX and FoxTelem guis at the same time is a
major processor drain. Usually FoxTelem will give up the ghost a few
seconds in. If I switch off of the input tab into one of the spacecraft
tabs, the processor usage drops dramatically and then I continue on. But
this is on a 10 year old laptop so who knows.
