K4AMG will have a complete all mode SATCOM station inside at Frost Fest this
weekend. NO QSOs the antennas will be inside, but the system will be
tracking.

Hi
(attempt #3 at sending this mail. maybe this list doesn't allow
attachments?)
Tomas SA2TMS here. I am involved in a group that's trying to put
together a scientific probe that will hitch a ride to the moon,
courtesy of PTscientists (one of the Lunar XPrize teams) [1,2]. One of
my major concerns is how get a reliable backup link going for running
operations during the lunar night. The lander acts as downlink relay
during the lunar day, but is not available during the night (and likely
not after the night either). Hence the need for a secondary link.
Throughput requirements are quite modest, as little as 10-100 bits/s
may be acceptable. There is an average of around 800 mW of electrical
power available. The geometry is somewhere between a 4U and 5U CubeSat.
I have two questions for this list, assuming it's the right place to
ask them:
1) What are some transceivers that may be suitable for this problem? I
have found some candidates, but I'm interested in hearing more
suggestions. The path loss is obviously quite significant (197 dB on
70cm). Choice of band(s) comes down to possible antenna geometries. 2m
is a bit on the low side for a dipole to fit (it'd have to fold). 70cm
is OK. At 23cm and above patch antennas start to become feasible (a
huge plus).
2) Where do I go to apply for frequency allocations in the amateur
satellite bands? Some sources say IARU, some say AMSAT. Others indicate
I should talk to my national agencies (PTS, SSA).
That's all for now. If you have any questions, ask :)

I decided to try receiving and decoding the AO-85 Data Under Voice
telemetry, but it's not working. I suspect it's because my radio is
filtering out the frequencies below 200 HZ.
So, what are folks doing to get this telemetry?
If you want to just point me to an old thread on the forum or a file on the
AMSAT site, I'm OK with that.

An RTL-SDR dongle or other SDR works great.
Most HTs don't provide unfiltered FM output unless they are advertised
as 9600 baud packet ready. Many mobile radios do, again, if they are
advertised as 9600 baud packet ready.

I've been considering getting one of those. That might just be the
excuse that I need. Thank you, Paul!
Can you recommend a couple or list a couple to avoid? I tend to be cheap
(and regretting it a significant amount of the time).
Other suggestions and ideas are still welcome.

Steve,
The FUNcube Dongle Pro+ is probably the best option if you are
wanting to copy telemetry from AO-85 or AO-73. AMSAT's FoxTelem
software for AO-85, along with the FUNcube Dashboard for AO-73,
are designed to directly control that dongle. The FUNcube Dongle
Pro+ is also a good receiver for working other satellites.
Another good option would be the SDRplay receiver. This performs
well for satellite work, but you would need to use another program
to control the SDRplay, along with a virtual audio cable to tie
that program to either FoxTelem or the FUNcube Dashboard. The
SDRplay can't be controlled directly by FoxTelem or the FUNcube
Dashboard.
The inexpensive "RTL-SDR" dongles could also be used, but these
lack the front-end filtering of the FUNcube Dongle Pro+ and the
SDRplay. For receive-only situations, the "RTL-SDR" dongles
might be an option. You would have to use a program like HDSDR or
SDR Sharp to control the dongle, then a virtual audio cable to
tie that program to FoxTelem or the FUNcube Dashboard. But if you
have any intentions of using an SDR receiver/dongle as part of
a station where you will transmit to satellites, you would probably
want to avoid these dongles.
The FUNcube Dongle Pro+ is sold by its UK-based manufacturer,
through its http://www.funcubedongle.com/ web site. With shipping
to the USA via FedEx, these cost around US$ 190 to US$ 200 depending
on exchange rates. The SDRplay receivers cost US$ 149 from HRO stores,
or they can also be purchased directly from SDRplay in the UK for
the same price plus an additional shipping charge.
Good luck, and 73!

This version of FoxTelem uses a new datafile format. While we store our
data on
the server in an SQL database, we use a flat file database for FoxTelem. A
flat
file format is nearly optimal for a program that mostly adds new data to
the end
of a growing list. With that said, we need to be able to load sections of
the
data into memory for efficient analysis. The new data file format allows
that.
If you have been downloading data from the server for analysis, you will
see
that this format is much faster.
One major change is the ability to automatically switch between low speed
and
high speed. This will help unattended stations gather as much telemetry as
possible. The "auto" mode actually runs both decoders at the same time, so
make
sure your computer has enough CPU power to cope.
Graphing has been updated to support better analysis of the spacecraft by
the
AMSAT Operations team and amateur scientists everywhere.
This version also contains new features that will be required for
Fox-1Cliff
and Fox-1D.
You can download it here:

http://amsat.us/FoxTelem/mac/FoxTelem_1.03_mac.zip
http://amsat.us/FoxTelem/linux/foxtelem_1.03_linux.tar.gz
Version 1.03 Changes
* Support larger volumes of data with much better speed in a segmented
database
* Auto detect high speed vs low speed telemetry
* Allow the user to swap IQ channels in IQ mode
* Allow graphs to be plotted as points (without lines)
* Plot more labels on horizontal axis when many resets plotted and fixed
some graph formatting issues
* Graph formatting parameters are saved to config and reloaded when
FoxTelem is restarted
* When reset button pressed on graphs the average period is reset too
* Swapped min/max values for solar panel temp on 1A
* Fox-1A Solar panel voltage was (incorrectly) using the MPPT conversion
* Fixed bug where HighSpeed Frames were unnecessarily held in the queue
until the pass was finished
* Cap max RSSI in the lookup table at -140dB to avoid spurious readings
* Interpolate the middle of two samples for first difference calculation,
for more accurate TCA calculation
* Add SAFE mode bit to the Computer panel so that it can be graphed
* Fixed bug where Radiation Graphs did not open at start up
* Fixed bug where T0 file could be corrupted if URL returned bogus data
* Fixed bug where FoxTelem gave many error messages but did not quit if
the log dir was not writable
* Skip NULL values for some measurements. Don't plot continuous labels to
left of vertical axis.
* MEMS diagnostic values are now in dps (vs Volts)
* Fixed bug where radiation data could not be saved to CSV files
* Fixed bug where FindSignal failed to lock if Track Doppler was not
checked
It also provides Support for Fox-1Cliff and Fox-1D:
* Display HERCI High Speed frames on the Herci Tab
* Display HERCI Housekeeping frames
* Support the Fox-1D low res camera format
* Implemented MPPT panel temperature conversion using Cubic fit
* Sort camera images by reset and uptime not picture counter
* Save position of the HERCI HS tab horizontal divider
* Allow the user to specify the number of thumb nails to display on the
camera tab
* Display converted HERCI Housekeeping data

Thanks for the new software. Sounds like a lot of work has been going on in
the background.
One question..........Will version 1.02 still send data to the server or
will it simply stop working as did 1.01 after the last update?

Great question David, and sorry about the mix up as we switched servers.
In this case, V1.02 will keep working fine. These are additional features

Chris,
Thanks for the announcement of the new version 1.03 of the FoxTelem
software. I downloaded it and put it on one of my Windows 10 tablets
this evening, a WinBook TW100 with 2 GB RAM and an Intel Atom Z3735
CPU. This tablet isn't like the Microsoft Surface tablets, but it
has worked well with previous versions of your FoxTelem software.
The new version, with the auto-detection for the data speed,
seems to work well on this tablet. I have another tablet with the
same Z3735 CPU, but with just 1 GB RAM, that I will test this on.
Since I am using an SDRplay receiver, I also use HDSDR to make my
RF recordings. Then I play those recordings back through HDSDR and
a virtual audio cable into FoxTelem.
After working a couple of AO-85 passes this evening, I ran my RF
recording through the previous version of FoxTelem, v1.02, for my
uploads to the AMSAT server. I decoded 40 frames from the 0302 UTC
pass, and 78 frames from the 0442 UTC pass. After I made those
uploads, I disabled uploading data to the server, disconnected
from my WiFi network in the house, and ran the same RF recordings
through the new v1.03 version. No CPU or memory issues on the tablet,
and more frames were decoded - 57 from the 0302 UTC pass, and 80
from the 0442 UTC pass.
I didn't expect to see a gain of 17 frames from the 0302 UTC RF
recording, so I reran that through the v1.02 version. For whatever
reason, I decoded 53 frames the second time I used the older
version of FoxTelem. This is still 4 less than what the new v1.03
version decoded, which seemed to be more in line with the improvement
I saw from decoding the data from the later pass.
For the passes I work over the weekend, I will run my recordings
through the v1.03 version. Since the CPU utilization on this
tablet appears to be little changed from the v1.02 version, I
think this will be fine for my situation (using the inexpensive
Windows 10 tablets to decode AO-85 data). I will also try the new
version with my FUNcube Dongle Pro+, to see how well it works
with another SDR receiver, and so I can just run FoxTelem without
the need for HDSDR running at the same time.
Thanks again for your great work on FoxTelem. Have a great weekend,
and 73!
