Hi Zach,
If you haven't sent the frames to the server, you can certainly send
them when you do your play back later. As long as they are unique to
your station they will be added to the data and your telemetry count.

Hi!
It was fun to see the launch this morning on NASA TV,
even though there were too many clouds around the launch
site to let me see any of the launch from outside my
house here in the Phoenix area. Then I loaded the FoxTelem
software on my Windows 10 tablets during the day at my
office (along with Java), along with using my FUNcube
Dongle Pro+ instead of my SDRplay SDR receiver, and tried
copying some telemetry on a couple of passes tonight.
The first pass, just after 0120 UTC, was a 13-degree pass
here. I copied the voice announcement about the satellite
being in safe mode, and a couple of data packets. I did
not have Upload to Server selected (who reads the manual,
when there's a new satellite to hear?!). I also ran HDSDR
during this pass, so I could make an RF recording at the
same time. I was able to play the HDSDR RF recording in
FoxTelem to get my two data packets up to the server.
The pass just after 0300 UTC was the best of the passes
tonight. Again, FoxTelem and HDSDR on the tablet, and a
57-degree pass. For this pass, the voice announcement
wasn't saying anything about safe mode, but I only copied
one data packet. This time, it was uploaded to the server
automagically. HDSDR made an RF recording. This time,
the CPU on my 1 GB RAM 8-inch tablet was pegged at a few
points in the pass. This leads me to believe I'm OK with
either FoxTelem or HDSDR, but not both. HDSDR can make
the RF recording in real time, then I can just play it
in FoxTelem without needing to deal with virtual audio
cables or (for some computers) Stereo Mix to pass the
audio from one program to the other.
I had one more shallow pass, around 0448 UTC, with a
maximum elevation of 8 degrees. After seeing that the
transponder was activated until 1000 UTC, I left the
SDR stuff inside, and took a couple of HTs outside with
me (KG-UV9D, KG-UV8D) with my Elk antenna. I heard the
voice announcements every couple of minutes, but never
heard anyone through the satellite during this pass. I
had the KG-UV9D connected to the Elk, and an audio
splitter to feed an earpiece and my Sony audio recorder.
Since I was not able to hear myself - or anyone else -
talking through the satellite, I did not connect the
KG-UV8D to the antenna. That will come soon enough,
hopefully - along with a few other radios that don't
work full-duplex with SO-50, but may work fine with
Fox-1A that way.
The two RF recordings from the earlier passes, the MP3
audio recording from the late pass, and lots of photos
and screengrabs were uploaded to my Dropbox space. Some
of the photos show the settings I used in FoxTelem and
HDSDR. Those files are located at:
http://dropbox.wd9ewk.net/
Look for the folder "20151009-AO85_Fox1A" for these files.
(refresh the page or hit F5, if my Dropbox public folders
don't come up straight away)
You can run both FoxTelem and HDSDR at the same time,
provided they use the same center/LO frequency and HDSDR
has an input bandwidth of 192000 (192 kHz) from the FUNcube
Dongle Pro+. A computer with more CPU horsepower should
not have issues with these two programs running at the
same time, but the Windows 10 tablets may have occasional
challenges. Thanks to Chris Thompson for quickly answering
my e-mail question about the bandwidth FoxTelem uses when
receiving data from a FUNcube Dongle Pro+! I have previously
run the FUNcube Dashboard and HDSDR at the same time, as
long as I kept the two programs in sync with the same center
frequency and input bandwidth.
This was a great day for AMSAT, and for satellite operators
around the world. Almost 6 years to the day the AMSAT Fox
project was unveiled at the 2009 AMSAT Space Symposium in
Baltimore (that happened on 10 October 2009 during the
annual general meeting), we now have the first of a series
of Fox-1 satellites in orbit. Some have even been able to
talk through the satellite, with many more hearing the
voice announcements and copying telemetry. Congratulations
to all who have had a hand in building and launching
Fox-1A today, and thanks to everyone who has supported the
Fox project over the past 6 years!
73!

Content-Type: text/plain; charset="us-ascii"
I've been reading this list for a while, decided it's about time I posted
something. I attempted to decode the Fox-1A telemetry on 2 passes over
Arizona today (approx. 0130 and 0300 UTC) using my Kenwood TS-2000 without
success. I configured it for 9600 packet operation, monitored the audio out
of ACC2 connector and could see over 20 Khz of audio bandwidth using
software based audio spectrum analyzer. Audio response looked good from 0
to 20 KHz so I thought I would be good to go. Nope. I fed audio into 2
different sound card devices - one being the RigBlastger Advantage set to 48
KHz sample rate and the other audio device being my Laptop's built in sound
card mic input set to 48K and 96K on different attempts. Audio levels were
adjusted so as not to be excessive and sounded clean when played back
through the speaker.
When attempting to decode, I could see a very nice eye pattern in the
telemetry decode software but the data square waves were pointy looking as
if some high frequency filtering was being applied to them. I' not
conclusively saying the TS-2000 won't work but I did everything right and
tested as thoroughly as possible prior to the actual satellite passes with
no success. I'll try again and see if I missed something and report back.
What DID work for me was decoding the signal via SDR. In this case It was
an RTL-SDR dongle in direct sampling mode connected to the 10.695 Mhz IF of
the TS-2000. HDSDR was used with output bandwidth set to 96 Khz. Audio was
piped to Fox telemetry decoder via VB Virtual Audio Cable software.

AO-85 OSCAR Number Assigned for Fox-1A
Willian (Bill) Tynan, W3XO, AMSAT-NA OSCAR Number Administrator has
issued the
following release:
I have been informed of the successful launch today, October 8, 2015 of the
AMSAT-NA-built Fox-1A CubeSat. I am also informed that the satellite has
been
heard by several amateurs in various countries.
This successful launch comes after years of diligent and dedicated work
on the
part of AMSAT-NA volunteers including Tony Momteiro, AA2TX, who became a
silent
key in March, 2014. It was Tony who spearheaded and guided the work on all
AMSAT-NA CubeSats until his untimely passing. Thus, it is only fitting that
this spacecraft be dedicated to his memory.
Following Tony?s death, the work of completing and preparing for launch fell
to Jerry Buxton, W0JY, who took over Tony?s post of AMSAT-NA?s Vice
President
for Engineering and saw to Fox-1A?s successful completion and its
preparation
for launch.
All of those who had a part in designing, constructing and testing
Fox-1A and
its various subsystems are to be congratulated for jobs well done.
Since Fox-1A was properly coordinated through IARU as an Amateur Radio
satellite, has been successfully launched and its signals have been
received;
I, under the authority vested in me by the AMSAT-NA President, do hereby
issue
to Fox-1A the designation AMSAT-OSCAR-85, or AO-85.
May AO-85 serve the radio amateurs of world for many years to come.
[ANS thanks Bill, W3XO, and AMSAT-NA for the above information]

I attempted two passes of AO-85 from DO20 after Jerry's email regarding
activation of the transponder.
During the first attempt with an Alinco HT at 0447 UTC I didn't get into
the bird (approx 4 watts into an Arrow antenna). I was, however, able to
copy AC0RA for most of the latter half of the pass.
I tried again at 0629 UTC using 20 watts TX power on an FT-857 (and the
Arrow). This time I was able to get into the sat from within a degree or
two of AOS to about 6 degrees near LOS. It took a fair bit of playing with
the TX frequency and antenna polarization. Unfortunately nobody else was on
:-(
One thing I noticed on both passes was that I had to tune my RX frequency
down by 5 KHz during the last quarter of the pass.

Bill

All,
We will leave the transponder running until about 0000Z 10Oct. Feel free to
try it.
A couple of notes:
If the downlink isn't on, a few seconds of 67 Hz tone will turn it on.
Narrow FM may help with the downlink audio levels if you find it difficult
to hear.
You may find it takes a little more gain on the uplink than expected. I
encourage users to try their handheld yagis, remember to twist for polarity,
listening full duplex to peak your uplink.
During this time, the low speed data will still be active alongside your
voice downlink, so ground stations are encouraged to continue submitting
that to the server.

On behalf of all members of AMSAT-UK I send our congratulations the AMSAT
team in the USA for all their hard work in recent years on FOX-1A which
having been successfully launched, and from which telemetry signals have
been successfully received and decoded on earth, is now known as AO-85. This
is a great achievement. I wish the team well during the forthcoming
commissioning, and we all hope that the new satellite will have a long and
useful life operating in the Amateur Satellite Service.

at 10:08 UTCwas strong, heard KC4LE, N8MH, KA4H, and others, but only had
one station answermy call in FN10.

It seems the uplink is 5-10 kHz high. Also, you really need to twist
the Arrow to peak the uplink. Half duplex will be a real challenge.
As KO4MA suggested, narrow FM is a big help with the downlink.

Hi All,
On the 10utc pass this morning, while the transponder was on and in use:
I learned that reducing the width of the cutoff filter in Foxtelem program
made it so I could copy the subaudible telemetry packets with the Funcube
Dongle Pro. Reducing from the default 200 Hz to about 180 or 175 seemed to
work here. It shows up as a decent eye pattern after that.
Another FYI-When playing back an IQ recording via SDR#, it seems a bit more
forgiving, working well around 175-200.
Suggest folks experiment for best copy! Share hints here, please!
73,

All,
Using detailed doppler measurements I find that GomX 3 is
object 40949, 1998-067HA.
Therefore AAUSat 5 is object 40948, 1998-067GZ.

Chris,
I had another chance to experiment with the FoxTelem program this morning.
On a 57 deg pass using?FCDP+ in IQ mode. I could see the carrier come up
nicely in the spectrum, but the vertical line cursor was hunting to the
right. When the carrier came up the cursor slowly started to wander in the
direction of the carrier, but never even came close to making on
frequency?before the transmission stopped. It is definitely not as
responsive as the FUNcube capture programs cursor which snaps to the carrier
as soon as it sees it.Is there a setting that can?up the response time of
the frequency track-and-lock cursor?
You can duplicate this issue by simply opening the program in IQ mode and
transmitting with a low power HT. It sees the spike, but?takes about 15
seconds to finally make it to the carrier frequency.
thanks for all your hard work on this project.??Michael?- KC4AVAAMSAT member

Using Funcube+ on the FoxTelem program. Saw spike during Fox-1 transmission,
moved the cursor by hand to the carrier spike. The eye and the window next
to it sprang to life, but never decoded anything.
If I disable the audio filter and unsquelch the program, key up my HT into a
dummy load on 145.98 it sounds like a steady buzz even when I'm talking.
Shouldn't I be able to hear myself over the telemetry program?
I thought there was one moment I could hear the girl saying Fox one on the
telemetry program, should I be able to hear her audio?

Great question Michael.? Don't know.? Find Signal is experimental.? Try it

moved it with the mouse and it then locked in and I just caught the ending
audio come over the speaker.
