Hi all,
Using a recording of Scott K4KDR, I've been able to decode telemetry of
the 3CAT2 satellite, which transmits 9k6 AX.25 BPSK telemetry in 145.970MHz.
To my knowledge, this is the first time that an Amateur decodes signals
from this satellite.

Message-ID: <0f480cdf1a7a47556a86fc04cd91fba9@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset=UTF-8
My understanding of Gravity Gradient is that a small spacecraft with a long
boom and tip mass will align in an UP/Down attitude. But it is bi-stable
so either end can be up and be stable.
What about a small satellite with TWO booms (dipole wires) in opposite
directions with small tip masses, it will be just as stable as before but I
may even get by with half the mass on each end. More or less. When I mean
?stable? I mean roughly up down, anything within +/- 40 degrees is still a
vertical HF antenna?. Besides faraday rotation will rotate the received
pattern every whichaway anyway.
I disagree with an opinion I have received that says ?gravity gradient?
wont work with dual opposite end tip masses. Says one has to be bigger and
it cannot be in the middle. I disagree.
Any professionals have an opinion?

I just had the ISS and NO84 both in my footprint for 4 minutes ~2228-2232 UTC.
I was driving and only had my VX-8 with a rubber duck. I CB usually hear the
ISS and occasionally capture its packets. With NO-84 I can sometimes hear
the packets but not capture them with the HT.
What I am wondering is with a better setup and time to work them:
A. could I Digipeat both of them at the same time?
B. Would they Digipeat each other?
C. Could I digi through them both
D. How Would be able to tell ?

A. yes
B. I think all NO84 sourced beacons attempt to go via ISS always
C. Yes if you use the path AIRSS,ARISS (*)
D. Look at the path of the digipeated packets. All D72 and D710 radios
now have a display page for the path
(*) Don't bother going from PSAT to ISS since PSAT is only 300 mW.
Instead, use the specific path VIA RS0ISS,ARISS and it will hit ISS first
and with its 5W then there is a chance that NO-84 will hear it and
digipeat it.
I have not done it in years, so I assume that ISS repsondes to both ARISS
or RS0ISS. And PSAT responds to PSAT and ARISS...
To see the dowlnik see: http://www1.findu.com/cgi-bin/pcsat.cgi
But it is confusing. This packet was only digipeted by PSAT having used
The alias of ARISS on the uplink. PSAT then marked the ARISS as used up
and inserted
Its callsign in the path to show that it did it.
K0KOC-7]APWW10,PSAT,ARISS*,qAR,VE2GQF-2:
If it had been a dual hop using the path of ARISS,ARISS, it would be:
K0KOC-7]APWW10,PSAT,ARISS,RS0ISS*,qAR,VE2GQF-2:
Since the ISS would use the second ARISS and then substitute its call in
place of the ARISS that it used.
Or if the user had used the used the path of ARISS,ARISS and it went to
ISS first and PSAT second, it would come down as :
K0KOC-7]APWW10,RS0ISS,PSAT,ARISS*,qAR,VE2GQF-2:
Unless I have had too much ocoffee and am not thinking clearly...

A quote:"The mass on the end of the dumbbell closest to the center of
the earth is attracted to it by a force that we denote F. The force on
the other mass we will denote f. Even if these masses are equal it is
easy to see that force F will be larger than f. "
The article goes on to say that the torque produced will keep the closer
end pointed towards Earth. This paper actually starts with the
assumption that the two end masses are the same, then goes on to say
that it will still work even if the masses are different.
So, I'm siding with Bob.

We?re only a few days from home; had a wonderful time exploring New
England and the Canadian Maritime provinces. During our trip, I took the
opportunity to practice operating portable. My thanks to K8YSE, N8HM, and
W5PFG for their advice and encouragement.
The current count is 20 grids activated, some rare and some not so: GO10,
GO11, GO21, GN07, GN08, GN09, GN18, GN19, GN38, FN02, FN03, FN23, FN34,
FN41, FN43, FN46, FN67, FN75, FN76, and FN96.
215 total QSOs. Thank you to everyone for their patience and for allowing
me to monopolize many satellite passes.
If I didn?t hear you, my apologies. I don?t hear well (i.e., hearing
aids) and I don?t hear well (i.e., pointing the antenna and tuning the
radio). I still need lots of practice and I need to work on my equipment.
All of my contacts have been uploaded to LoTW. If we made contact and you
aren?t getting a confirmation via LoTW, please contact me so that we can
discover my mistakes.
Hopefully we can do this again on my next trip. Best way to hear about
any operating plans are to follow me on Twitter @xxxxxxx.

I encourage everyone to try to work them. The more calls in the log, the
more likely they are to include satellite again next time.

Just saw this on Twitter from WW2DX. Go get them! Even if you don't
normally chase grids or DX, please do get on and work them! As Drew

St. Paul is very easy to work on satellite. Good op, station hears well.
Just take your time, no need to step all over one another. He was lonely

Although quite some time has passed since our last update the SatNOGS
team and the community was busy working on it?s software and hardware
components allowing modular setups.
A large amount of focus has being the SatNOGS client software.
Allowing the user to not only use RTL-SDR based dongles but a far
greater variety of SDR solutions using GnuRadio. In conjunction with
that SatNOGS client is able to use Amateur Radios that are supported
by hamlib (we?ve already tested on Yaesu and Kenwood radios). Such
functionality paired with our new ground station hardware design, and
further tests on after market designs such us Yaesu Az/El rotator
would allow the SatNOGS network to not only receive but transmit data
via the network to satellites.
Since a few months now Libre Space Foundation, the organization that
assists the development, and operation of the SatNOGS networks is has
being working together with the University of Patras on developing and
manufacturing the first satellite with most of it?s components based
open hardware and using free software, UPSat.
An open hardware and software satellite especially one build by Libre
Space Foundation would be a great chance for the SatNOGS network to
implement command and control features on it?s SatNOGS client,
allowing a fully open Low Earth Orbiting satellite communication stack
from earth to orbit and back.
Communications with the satellite are implemented through ECSS
Standard Commands as described in ECSS-E-70-41A standard (CCSDS). You
can checkout the code of the client on GitHub and the ecss services
implemented on the satellite here. There has been a lot of effort to
make sure that we implement all needed functionality on the SatNOGS
client, while in parallel maintaining modularity and extensibility for
future satellites and other protocols.
Do you have a satellite in the works and want to use SatNOGS client as
command and control? Let us know and we will be happy to work with you
expanding our client!

Hello Daniel,
It is very good to see the development of more sophisticated ground
stations to operate cubesats and other amateur satellites. Besides the
development of more advanced communication systems and protocols, this is
an area where I think there is a lot of opportunities for development.
During the last Cubesat Workshop that took place in Florian?polis, Brazil,
there were some discussions about some areas in the design of a remote
controlled ground station that needs attention. More specifically, the
notion of a control operator in the amateur radio service (assuming the
station will operate in the amateur radio service). It is not always clear
who is the control operator when a station (transmitter) is being operated
remotely, specially if the operation is automated. Things get worse when a
station (transmitter) is being remotely operated from a different country.
This issue can potentially raise eye brows from a regulatory perspective
and I believe it would be very important for each project that will
implement remote operations to clear the details with the national telecom
administrations involved in order to comply with the amateur radio
regulations and avoid stepping into legal issues.
