Today I copied the spectrum of signals received from ARISSat with an SDR-IQ
(and?homemade VHF / HFconverter ) and SpectraVue. The frequencies listed
are the transmitted by satellite, and Doppler effectis clearly visible in
the received signals, with higher frequencies?at the beginning and lower at
the end of the pass.
The noise generated by linear transponder and the return of the transmission
that I did in the UHF uplink are?clearly visible. The CW-2 signal close to
the 1kBPSK telemetry signalcan also be seen, as well as FM transmissions,
switching between voice and SSTV.

Well done! It is nice to see someone using a mixture of commercial and

and for the record, AMSAT-UK has a working design for a 29.45 receiver
with 42dB of AGC, crystal filters for the passband, audio buffering /
filtering with a bonus 10.7MHz I.F. output.- Just in case you want to add a
TX up
or downconverter for a linear transponder. - Downside is that although the
board is small, it's not the cubesat format
Thanks

The A#1 Killer AP is something we have tried twice on short li=ved missions
and which we already have ready for our next mission, (but no launch
opportunities) is a PSK-31 transponder.! It is really more than you first
think: Please see:
http://aprs.org/psk31uplink.html
1) Normal HF PSK-31 uplinks on 10 meters where the Doppler is 14 times less
than on the typical UHF downlink.
2) VHF or UHF *FM* downlink. Notice FM. This means what EVERYONE see's on
their waterfall is EXACTLY whateveryone else sees. Thus, everyone just
jumps into the 3 KHz FM audio bandwidth wherever they see an empty spot and
then can even see THEMSELVES full duplex because they are transmitting
linear PSK-31 on the uplink on 28.120 while simultaneously seeing what
everyone else is seeing on the VHF or UHF FM downlink.
3) Because you see what every one else sees, including yourself, you can
SEE
your good signal or your bad signal, AND you see how you are shifiting in
Doppler and can correct for it.
4) AND because it is full duplex, you TX the entire pass in a steady stream
while looking for QSOs in the downlink. We could have 20 to 30
SIMULTANEOUSE QSO's going on at the same time and even be talking to all at
the same time.
It is the ULTIMATE satellite transponder, because:
1) Full duplex
2) Minimal Doppler
3) You correct for your own Doppler
4) 20 to 30 simultaneous users
5) Free software, no hardware!
6) Vertical 10m antennas are IDEAL power-levelers. When overhead (and 10
dB
closer) the signal arrives at the satellite 6 to 10 dB down due to the
vertical antenna pattern.
It's a win-win-win mission. Our attempt failed on PCSAT2 due to a broken
antenna (pre-launch integrators and astronaut handling) and our attempt on
RAFT failed due to not enough time available for the tests due to mission
conflicts during a shor 5 month mission.
Please someone do this. It is TRIVIAL to do. Just combhine a 28.120
PSK-31
receiver and a VHF or UHF FM transmitter. Done.

I have been using object D and it does a fair job in keeping up with the
Doppler shift. The signal get up to 6db above the noise with fades in the
noise during the pass. I have a 15 db gain antenna and a system noise figure
about 2 db.

Hi Steve,
I don't agree that "the more people that get a taste of satellites, the
better".
AMSAT will then turn from quality into quantity, with a high risk that it
will get out of control (RF wise and launch space wise) with so many small
sat projects.
Now everything is scattered into small satellites (mostly CubeSat) and the
big satellites that can unite the international AMSAT community are pushed
backwards into the big crowd.
Every real AMSAT ham still knows about the AO10, AO13, AO40, FO20/29... even
after they stopped working. I wonder how many will remember all those Cubes...
I would more like to see that people get interrested in the technology and
try to get there ham license because of interrest in technology.
Nowadays a license is not really needed, just a dongle and software and you
can say you are working on satellites.
Nice for students to get "a taste from the small cookies", but not to "have
a big meal when you get more hungry", as there is not many big food
available (big satellites).
I really support the idea to help newcommers, but in my opinion it is
getting out of balance...
(I believe due to the commercial and publicity value of those Cubes...)

I did notice a change in the change in the Temperature Status during the

Some of you may have heard that a team in the UK are trying to
re-contact and old British launched satellite for the anniversary of its
launch (28th October 1971).
We've been given a licence to transmit and will be testing our
re-engineered ground-segment in the next fortnight. The passes we are
going to concentrate on will be as far out west as possible, as to
minimise QRM from Europe. Earth is a lot more EM noisy than it was in 1971.
If anyone in the UK wants to try and tune in to the downlink, you can
help ID any response we get from the old bird. The passes are
summarised here:
https://public.sheet.zoho.com/public/rjaduthie/prospero-passes-in-the-next-for
tnight
There are other passes, though these are the ones which are out west.
We'll see how we do.

I'll let someone who knows more about this answer your question as directly
as possible. In the mean time, I would (sadly) point out that the US has a
law on the books with the acronym ITAR (International Trafficing in Arms
Regulations). The people who enforce it believe that satellite technology
counts as "Arms" (weapons) and so if we built a satellite and shipped it to
Korea (or even if we shipped it to the United Kingdom for that matter) we
would be threatened with huge fines and possibly jail time. Case in point,
AMSAT-NA had to pull out of the Phase 3e project with AMSAT-DL because of
the crazy way that this law is being enforced. I am especially sickened by
this fact because when I read the regulations in question, I see explicit
exceptions to the rule of what constitutes regulated "Arms" that ought to
apply to us. But I'm not a lawyer so what do I know?

Is it just me or has something happened to the power level on AO-51
recently? Ever since Frank & Clayton (K4FEG & W5PFG) 'broke' it Monday
evening on the 2130Z pass (just kidding guys), my receive audio has been
'scratchy' like I'm not getting enough signal into the receiver. Nothing has
changed on my end and though I usually run mobile, I was sitting in a
parking lot for that pass instead of driving down the road, I'm just curious
if anything got changed during the reset.
AO-51 has been my favorite satellite since I got started doing them 2 1/2
years ago and I cringe every time she 'goes down' knowing that we may never
hear from her again.

Not that I'm aware of. Ironically, I also have an email asking if the power
was increased after that short telemetry session.
Every pass now with 51 is a bonus. It should be inoperative by all measures
with 2 of the 6 cells shorted.

Hi Jeff,
I assure you, nobody broke it on Monday :) I simply had it in
telemetry mode in order to grab fresh telemetry (battery voltages,
temperatures, etc.). The bird never went down; I simply changed from
voice, to digital, back to voice.
No change in the power was made, it's still running just under 1 watt (980
mW).
The crazy thing has been operating without a crash for what---10-12
weeks now? I've lost track, which is a GREAT thing! It's a real
surprise that the bird is running on only 4 out of the 6 original
cells in the battery, all the way through eclipse at full smoke.
It won't last forever...so enjoy it while it lasts!

'scratchy' like I'm not getting enough signal into the receiver. Nothing has
changed on my end and though I usually run mobile, I was sitting in a
parking lot for that pass instead of driving down the road, I'm just curious
if anything got changed during the reset.

Almost 300 responded, able to choose multiple modes ...

Just to set the record straight, Frank/K4FEG broke it, not me. I am
an innocent victim in this sinister plot. I think he needs to be put
on double-secret-probation under the watchful eye of the other EM55
satellite operators.
If anything, I thought the power was increased after the telemetry.
After speaking with another on that pass who shared the same thought,
I emailed Drew to find out that the power is still set to just under a
watt. I can't explain why I saw a signal strength "bump" after the
telemetry download, but I know what I saw. Either way, that bird is
working great!
Kudos to the entire team keeping this satellite usable despite the
battery situation.
