Hi!
A lot of satellite work tonight, starting with a LilacSat-2 pass, then a
couple of AO-85 passes, and wrapping up with an SO-50 pass approaching
midnight (0700 UTC). Fun stuff, and a lot to scribble about...
The LilacSat-2 pass around 0130 UTC this evening was a nice and high
(almost 49 degrees maximum elevation) pass. One slight problem - the
repeater was off. Regardless of that issue, I listened to the pass
with my SDRplay receiver and Elk log periodic, copying the transmissions
using the HDSDR software on my 8-inch tablet. This also let me prepare
for the AO-85 pass a few minutes later, the first of two AO-85 passes
tonight.
My first AO-85 pass tonight, starting around 0150 UTC, went up the
center of the continental USA. As I expected, there was a lot of activity
on the new satellite. Glenn AA5PK was my first AO-85 QSO this evening,
and I logged 8 more QSOs over the next 10 minutes I was in the footprint.
I was using my Icom IC-2820H 2m/70cm mobile radio for the uplink, at 15
or 50 watts transmitter power (I could not get through with the 5-watt
low power setting during this pass). My SDRplay receiver along with HDSDR
on an 8-inch Windows 10 tablet for the downlink. I made an RF recording of
the pass using the SDRplay at 200 kHz IF bandwidth, hoping I could sneak it
through the Fox telemetry software and upload some data packets after the
pass. The telemetry program appeared to accept my RF recording, even though
it was at 200 kHz and the software was designed to accept 192 kHz RF
recordings from a FUNcube Dongle Pro+. Although the RF recording played in
the program, no data packets were decoded. The SDRplay did a good job
hearing the satellite; I think a little better than the FUNcube Dongle
Pro+. I had to twist my Elk log periodic almost constantly throughout this
pass. It was a nice pass to work, with a maximum elevation out here at 37
degrees.
The later AO-85 pass around 0330 UTC wasn't as high in the western sky, at
a maximum elevation for me at just over 24 degrees. This turned out to be
the first pass I tried one of my Chinese-made HTs, seeing if I could work
this satellite full-duplex. I actually set up two stations in my driveway
for this pass - Wouxun KG-UV9D and Elk log periodic I used to talk through
the satellite; and the FUNcube Dongle Pro+ and AMSAT-UK (Winkler) VHF
crossed dipole, connected to my 8-inch Windows 10 tablet and HDSDR to write
an RF recording of this pass that I could use with the Fox telemetry
software for a data upload after the pass.
Even though the KG-UV9D can tune in 2.5 kHz steps, I stuck with 5 kHz steps
for the uplink tuning. Being able to tune in 2.5 kHz steps did not appear
to help me work AO-85. With the sharper receive filtering in the KG-UV9D, I
set my downlink frequency at 145.9825 for the first minute or so of the
pass, and then moved it down to 145.980 for the next several minutes. Near
the end of the pass, I had to put the HT on 145.9775 MHz to hear the
downlink without the voices sounding off-frequency.
It seemed like I had to twist my Elk more often this pass. I also saw and
heard the fading on my SDR receive setup during the pass. A few minutes
into the pass, I was able to make my only QSO during this pass, a quick QSO
with Tom KA6SIP in northern California. The best part of this QSO, besides
being the first AO-85 QSO I made using a 5-watt HT... I was able to
complete this QSO full-duplex with the KG-UV9D! I could hear in the
receiver when I pushed the PTT, but unlike using this HT on SO-50, there
was no receiver desense as I transmitted to AO-85 on 70cm! This is a very
good sign, and I hope to repeat this using a couple of my other Chinese-
made dual-band HTs on upcoming AO-85 passes (Wouxun KG-UV8D, AnyTone
TERMN-8R). I was not able to get through AO-85 with the HT early or late
in the pass, but near the midpoint when the satellite was around 20 degrees
elevation or higher. I'll see if this is something that will be an issue
going forward, or if the commissioning process will lead to some tweaks on
the AO-85 uplink receiver, to make it a little more sensitive to lower-
power uplink signals.
After this pass, I took my HDSDR RF recording and played it in the Fox
telemetry software on my 8-inch Windows 10 tablet. I successfully copied,
and uploaded, 4 data packets from the 0330 UTC pass! This is one more than
the number of packets I received during two passes last night. Since I
used the FUNcube Dongle Pro+ as my SDR receiver, I knew HDSDR's RF
recordings - at the dongle's maximum input bandwidth of 192 kHz - would
work fine with the Fox telemetry software. Not a bad way to wrap up the
second of the two AO-85 passes - a full-duplex QSO on that HT, and helping
AMSAT with some data uploaded to the telemetry server.
To wrap up the evening, I worked an SO-50 pass from the back yard around
0625 UTC. A very nice late-evening pass, using the KG-UV9D as my uplink
radio and the SDRplay receiver with my 8-inch Windows 10 tablet and HDSDR
as my receiver. Only a few stations on, including Tom WA0POD, Tom KA6SIP,
and Frank K6FW - all who were on the 0330 UTC AO-85 pass a few hours
earlier.
A few observations, in no particular order...
During the 0330 UTC AO-85 pass, there was a 45-second period where the
downlink simply disappeared. Nothing was heard from the satellite. I could
clearly see this on my RF recording with my FUNcube dongle and HDSDR, and
a local friend of mine (Brad KG7NXH) also observed this at his station
in another part of the Phoenix area. When the downlink transmitter came
back on, it appeared that the downlink frequency ramped up to the nominal
145.980 MHz frequency - just like I saw when the voice announcements were
transmitted on the passes Thursday evening. I tweeted screengrabs from my
RF recording in HDSDR the moments when the downlink shut off and then
restarted:
https://twitter.com/WD9EWK/status/652715204287946752
This is also visible in the RF recording I made from this pass. KG7NXH
posted his screengrabs in a thread on the QRZ.com satellite forum:
https://forums.qrz.com/index.php?threads/ao-85.496019/#post-3621413
It seems like my SDRplay receiver is more sensitive than the FUNcube Dongle
Pro+ on these passes. I wish the Fox telemetry software had a little bit of
a "fudge factor" in the WAV files it can process. Since the SDRplay's
smallest bandwidth is 200 kHz, 8 kHz more than the FUNcube dongle's maximum
192 kHz bandwidth, I wonder if there is a way that the Fox telemetry
software could be tweaked to accept WAV files at either 192 or 200 kHz RF
bandwidth. This wouldn't mean the Fox software could directly work with the
SDRplay receiver, but certainly opens up the SDRplay as an option for
working the passes and having a usable RF recording that can be processed
by the Fox telemetry software. Now if I could use the SDRplay and the Fox
software to copy and upload data packets in real time during passes...
Even though the KG-UV9D and probably a few other Chinese-made dual-band
HTs can't work SO-50 full-duplex, they are probably going to be viable
options for a dual-band HT capable of full-duplex operation on AO-85 and
other Fox-1 U/V satellites. For many who have Icom IC-W32As that would
suffer from receiver desense on V/U satellites including SO-50, it is time
to dust them off - these should also be good for full-duplex operation on
the Fox-1 satellites, free of any receiver desense. The time has come to
prove - or, hopefully, disprove - statements about these HTs and their
ability to work Fox-1 satellites full-duplex. :-)
For all of the passes I worked and monitored this evening, I have uploaded
my audio and RF recordings, along with photos and screengrabs, to my
Dropbox space. You can get to those files at:
http://dropbox.wd9ewk.net/
Press F5 if the Dropbox page doesn't immediately appear in your browser
window. This is easier than pasting the long string of gibberish that
makes up a link to a public Dropbox folder. All of my files from this
evening are in folders with name starting with 20151010.
It is approaching the 48-hour mark since the launch of AO-85. Being able to
actually use this satellite, so soon after the launch, is hopefully a sign
that the satellite is in good working order. I know that AMSAT personnel
are still checking over the telemetry being downloaded from the satellite
and uploaded to the AMSAT telemetry server. I hope the 45 seconds of
silence heard this evening was a one-off incident. Add in the LilacSat-2
pass I heard early this evening, to the SO-50 pass just before midnight,
it has been another fun day to work satellites. :-)
Good night, and 73!

Yes, after trying everything that I could think of with no luck, it occurred
to me that I could dump the data that had been received previously (when
"upload" was turned off) and replay my I/Q file once again into the Fox
Telem software with "upload" turned on.
That worked, but only 4 packets uploaded even though the software indicated
10 decodes. Not sure why, but I was satisfied... I don't consider it a
competition; I really just wanted to get completely through the process and
actually have some data upload to the site.
I do have some observations that I'll share on the chance that it helps
someone else.
While several bit rates are available in the Fox Telem software on a
drop-down menu, the documentation recommends 48,000. So, before replaying
my I/Q file that last time, I reconfigured SDR# as well as the VB-Cable
audio link to both work at 48,000. Sure enough, I decoded many more packets
than I had previously. Going forward I'll capture the data with those
settings.
Last night's pass might have been unique in that it was a minute of
slow-speed data but then transitioned to high-speed. So, I had to replay my
I/Q file twice... once with the Fox Telem software set to slow data and
again with it set to high. However, I realize now that I could have easily
paused the playback in SDR#, stopped the Fox Telem input, switched to high
speed, and resumed the playback.
Since I'm not going to have an internet connection during the initial data
capture, it would appear that the correct sequence of events for my
configuration will be to only use the Fox Telem software during a fly-over
to give me some feedback as to how well I'm receiving. I'll then dump the
resulting payload and replay the recorded I/Q file with an active internet
connection and the Fox Telem software set to upload. It would be wonderful
if the software would "store & forward" the packets once online, but this
might be a blessing in disguise as there is every chance that I'll have a
better result decoding under controlled conditions where I'm don't have my
hands full with an antenna, etc.
Also, I see that many people with more advanced setups are able to play
their recorded I/Q .wav files directly in the Fox Telem software. I did not
have any success with that and I actually liked replaying my recordings in
SDR# so that I could verify that I was centered on the carrier and make
minor frequency adjustments. I was also tweaking output levels on replay.
I didn't really know if there was any benefit in that, but I told myself
that I was keeping the waveforms on the Fox Telem software as "clean" as
possible in hopes of more decodes. Similar apps give some level feedback so
you'll know if you are feeding it at the right volume, but it's still a
really nice app.
At any rate, I was pretty tickled with any success at all and VERY
appreciative of the information that others have shared.
In summary, my setup is:
-Arrow dual-band antenna (will test some future passes with omni QFH when
elevation is high)
-$20 RTL-SDR dongle
-SDR# on Windows-7, FM-narrow @ 32k bandwidth with audio set to 48,000,
doppler tracking from Orbitron
-VB Cable set to 48,000
-Fox Telem software with AF input set to VB-Cable @ 48,000

My Fox 1 Telemetry Analysis Tool is showing "Decoded: 8" and "Queued: 0" at
the
bottom of the screen.
I have my station details complete and the box to
"Upload to Server" is
checked.
Not seeing my call sign on the Leaderboard
Statistics page, but I have no
idea how long to wait before I should expect
some feedback from an upload
to be reflected on that page.
Is there some way
to know when the Windows App has completed an upload
successfully?
I have
logging enabled and see a line as follows:
=====
Trying Primary Server:

... but no indication of a successful -or- failed
upload. I do have an
active internet connection.
Many thanks.

Nick,
I am traveling, so have not had a chance to use live data. PowerSDR
attenuates the audio significantly below 300 Hz, but is not a brick wall.
You can hear and see the PL tones on a local repeater. During pre-launch
testing, I was able to play I/Q files through PowerSDR and get fair copy of
telemetry, but not anywhere as good as through a program which does not have
low pass filtering, such as SDR#. Dave, W0DHB suggested switching to I/Q
from PowerSDR to FoxTelem which _should_ bypass the filtering. I will get a
chance to test it in a few days.
I found the secret of getting audio from the monitor is to turn it on. :)
The button label is backward to my thinking. You will need to uncheck some
of the filtering boxes to get full voice audio.
73s,
Alan

Hi Patrick
Interesting observation about the Chinese handhelds being able to work full
duplex on AO-85 (U/V)
but not on SO-50 (V/U)
I saw some testing figures for harmonic output which suggested some radios
use a single low pass with a cut-off just above 70cm, but the 2m transmitter
uses the same filter.
This meant the 3rd harmonic from 2m was very high and fell in the 70cm band
de-sensing the radio.
What you have proved (hopefully) is that there are no outputs from the 70cm
transmitter which interfere with the 2m receiver and that the receiver front
end is not de-sensed when transmitting up to AO-85.
Nice.....
Thanks
David

Patrick,
I downloaded your RF recordings and was able to decode 41 telemetry payloads
from your 0130 UTC pass by playing your recording out from HDSDR at 96000
output bandwidth and piping the audio to FoxTelem. That's a LOT more than I
was able to decode on my own downlink at home. Since you were using the Elk
antenna and able to twist for polarity fades, your receive signal was much
better than mine hence more decodes.
I would think that for anybody using an SDR other than the FunCUbe Dongle
that recording the RF then playing back as audio into FoxTelem would provide
a solution to the incompatible .wave file sample rates (192K vs 200K).
Thanks,
Brad Schumacher

Your description sounds like you caught Fox-1a in high speed data mode. We
are still doing some commissioning so expect mode switches without
necessarily hearing any warning. If it sounds like "an old fashioned
acoustic coupler" (and if you are old enough to know what that sounds like
:-) try switching FoxTlm to high speed mode. For high speed mode you have
to be especially careful that there is no LOW PASS filter in the path. You
need 10KHz or more audio band pass. (For low speed you need to be able to
hear down to 20-ish Hz.)

Please note that while AO-85 is in Transponder Mode right now, we have
not officially commissioned her and testing is still underway.
Part of the testing involves observations in Transponder and Data
Modes. We may switch out of Transponder Mode at any time without
notice, until we are done testing.
If AO-85 is in Safe Mode or Data Mode when it passes and you were
expecting Transponder Mode, don't be surprised or angry!

success anyone?

Hi,
Congrats to the AO-85 team!
Trying to decode telemetry using the 9600 output of the sub data (while
radio is in Sat mode) from my IC-910H. Has anyone been able to do
this? High elevation passes only?
9600 output is connected directly to mic input. No isolation
transformers, etc. Seems like those making progress have gone the SDR
route with IQ data?
Sound card input - 2 channel (L-R channels connected on cable), 24 bit,
48000 Hz
radio - cable to sub band data socket. 9600 bps transmission on. (Is
this for TX only, does not change output and can be left of?)
AO-85 software
Source - mic input, 4800
start --> no joy,
Suggestions welcome.
Thanks, es 73
