I know some of you have been asking about this for a while. I will be
heading "up north" into grid FN05 this weekend and should be able to make
some contacts on the arrow from FN05 in Ontario this weekend. If you worked
me last week in FN04/14 and want a qsl, pls contact me via email or send a
card to the qrz.com address as I did not keep a log.

Sebastian,
The bias T is for powering up the preamp if you didn't have the radio
that supplied power. I have these preamps and work well with my
IC-910 when I use them.
Good Luck,
Dee, NB2F

Before I destroy these, is anyone using Mirage KP-2 mast mounted
preamps with a Yaesu FT-847?
I picked up a couple of them recently, and they came with the control
box (which appears to be a bias tee) that supplies 12 volts via the
coax line, in order to power them.
The FT-847 can already supply 12 volts up the coax to mast mounted
preamps; but I wonder if these Mirage preamps require the use of the
control box for some reason. I would prefer to use the rig to power
the preamps, but the manual doesn't mention that option.

Hi Floyd,
Yes, you can. Recording the full 80kHz bandwidth for a 10 min pass
(duration of ARISSat-1 passes, roughly) creates a BIG wavefile around 250MB
in size. You can play it back and decode whatever you want, whenever you
want. I've been doing that regularly, which results in about 1GB per day
(4 passes recorded per day, on the average). Heh.
On one playback, I might decode the FM signal for SSTV pics. On another
playback, I might try to pull some telemetry out. On yet another playback,
I might listen around the linear transponder. It's really slick.
Surely we could pick out what we REALLY wanted and do a recording of that
output...but I haven't bothered to do so. I'm content playing back and
decoding whatever I want...

You can get an idea of how close to eclipse a satellite is by watching
Delphi tonight as it approaches daylight . It is solar only and will power
up just before aos shadow reaches the daylight line on Satpc32 tracker .
Interesting to watch.

Dont know about those particular ones, but I am using a pair of Dressler
mast mounted pre-amps with the 847. I supply the 12 V via the coax and they
perform beautifully.

I don't think it's rare, but if anyone needs EM84 on satellite, drop me an

Greg. well all I can say is that anyone who says that the US has "virtually
abandoned" crewed spaceflight is not up on current events. What we are
doing is transitioning from a program of the military industrial complex to
one which centers on private enterprise...and that will open space access
for a lot of things. And that will include amateur radio payloads. In my
view the association between amateur radio and human spaceflight has hurt
amateur radio more then it has helped.

What's was blocking my sound card decoding was as i read the sampling rate i
was using on sprectra view with the UK fun dongle. As soon as
i put 48000hz the CW decoder start to decoded but nothing on the TLM screen
yet (BPSK). I manually track the doppler shift and it not seems
to be very critical but i'm still in the dark about the BPSK data?

It's very easy to tell just by looking at a tracking map whether a
spacecraft is in sunlight. If any part, even a tiny bit, of the
satellite's range circle is lit, then the satellite itself is lit. Only
if the satellite's range circle is completely dark will the satellite be
in eclipse.

Content-Type: text/plain; charset=UTF-8
It's been suggested that I modify my ARISSat-1 BPSK-1000 telemetry
demodulator/decoder to accept wideband quadrature (I & Q) recordings
like those produced by most of the software defined radios out there.
This is fundamentally not that hard, but first I need some information.
How many people could actually use this? What is the format of the
recorded files? Is there a standard, or does each make of SDR produce
its own?
If I could get a good sample wideband quadrature recording of the
ARISSat-1 downlink that includes the BPSK beacon, I could use it for
testing. Ideally there would be no need for any manual tuning because
the wideband recording would always contain the beacon regardless of
Doppler. All tuning would be in the demodulator software.
This might be a little compute-intensive so I can't guarantee that it'll
run in real time on older computers. I already make pretty heavy use of
the Intel SSE (vector arithmetic) instructions for FIR filtering and
Viterbi decoding. The SSE2 set introduced with the Pentium 4 has been
especially useful, so I would consider the P4 (or the AMD equivalent) a
minimum requirement. Of course, the newer and faster the CPU, the
better. I also make use of multiple CPU cores, particularly during the
acquisition phase, so the newer CPUs with lots of CPU cores would also
be preferred.

With all due respect Robert, I think this is a pipe dream. The current
global economy is in serious, serious shape. 'Private Enterprise' may indeed
get into the field but even private enterprise operates on cash. Playing
around in space is way down on the food chain in these conditions. NASA has
always been heavily funded by the government and the current administration
has zero interest in participating further. The Russians have the upper hand
and their gov't seems willing to spend...for now. I'll bet you dinner it
will be years before you see another amateur satellite overhead.

Subject: [amsat-bb] Sample ARISSat-1 recording with Funcube Dongle
using HDSDR

Hi All,
I've been recording quite a few passes of ARISSat-1 using the Funcube Dongle
(FCD) SDR and the HDSDR program. The resulting file from a 10 min pass,
recording the whole FCD passband, is about 250MB. Below is a link to a
sample from this morning. The bird was in the sun, so it's transmitting
continually, making things easier.
This sample isn't perfect, but it's pretty good. It was made using my "low"
array, which is a M2 2MCP14 configured for RHCP. There is a good ARR preamp
at the antenna. When in the clear, it's quite good--but much of the pass
is through the house and/or trees....
You can play it back using HDSDR (google it). If you've never played with
SDR, you have some reading to do :) This isn't a "How To" but rather a
"here it is if you want it." (The imminence of another academic year
prevents me from doing a write-up with instructions...sorry.)
The recording was made with NO correction for Doppler. About a minute into
the recording (click to fast forward, back up, etc...it's slick) you'll see
signals--CW telemetry, the BPSK telemetry, the linear transponder, and the
FM voice channel. Move around, change modes, listen, etc. Back up at will,
just with a click.
If the bug really bites you, you can install Virtual Audio Cable (VAC) and
have HDSDR use it as the output, and then configure a decoding program (like
ARISSatTLM or MMSSTV) to decode telemetry and/or SSTV pics using VAC as the
input. It's neat. You can print SSTV without tuning for Doppler on
playback. That's not the case for the BPSK telemetry!
The file is BIG, nearly 250MB...

My thanks to everyone who has responded. 4 out of 4 say it's ok to use the
847 to power the preamp.
I put up the 432 one today, but with the KP2 control box, just in case. But
I will go ahead and remove the box, and let the 847 power it.
One interesting response was to be careful if there is anything inline
between the rig and preamp. Lightning protection, or even an SWR power
meter, could affect the sending of voltage.

I agree, that there is change that can happen. Here's my view on what I
really
think are the issues.
I was specifically referring to the notion that "funding" is the "problem".
Funding will be the "issue" that allows change to actually happen, and at what
speed it can happen. Money availability is largely controlled by the "Fed" in
terms of providing an interest rate that will allow private enterprise to
"invest" by getting loans from the banks that the Fed serves.
Sure, there is also a fixed amount of "money" available from private parties.
But, if no one who "has the money" wants to fund "space flight", then it won't
ever happen privately. I.e. why hasn't the privetization already happened? I
think it's because it doesn't "make money". There's nothing "known" to
generate
value out of space "flight". Space based research, perhaps, but not "space
flight". Transportation to the ISS is an occasional thing... Not a giant
opportunity for continued income and business growth (limited occupancy etc.).
There has to be some other interests generated. Nasa's exploratory program
can
provide the data and some "Wow moments" that raise the interest levels of
those
with money. But, if there is no "investment" opportunity, then a mindset
change
has to happen that causes people to believe that it needs to happen and they
should "pay" for it rather than "invest" in it.
Because of the development of "the space program" by the government of the
U.S.,
that's largely where it has been funded from, and the Fed, has "printed money"
for many parts of that development.
If there is only a "small" amount of private funding available, it may not
go to
the 'right' places. So, in order for "all possible opportunities to be
explored", there has to exist enough interests with enough money to make it
happen. Federally funded exploration programs are one way to make sure
specific
tasks are executed. But, because people believe that "money" is and should be
of a "fixed supply", we'll have countless arguments about "budget".
If we did something with a space program over the course of 10 years,
instead of
doing it in 1 year, for example, people would see less effect of the "money
spent" over 10 years. But if all of the economic impact occured in just 1
year,
it could have very recognizable impact, as the wars have in the past. The Fed
has moved the economy along at slow speeds because its easier to keep an eye
on it.
The amount of "cash" available, is arbitrary, because the Fed decides when to
print it based on their economic outlook and then decided interest rates.
They
are printing like mad right now because of the recession. This is the policy
and procedures of how the Fed works as an independent organization (no one who
you voted for can make them do anything).
As we all know, a huge mount of "value" was "injected" into our economy by
massive, risky, unmanaged credit. We didn't have the money in circulation to
support that value, and suddenly it was realized that there was a problem.
Next
was the decision about who loses? Is it the person making the purchase, or
the
person loaning the money, or the person who sold the risky item? It has been
decided that no one loses, and we'll just adjust the economy by printing money
so everyone can "do" what needs to be done to recover. Go watch the Fed vs
the
congress videos on youtube.com if you didn't get to see how much grilling the
Fed got for "fixing the economy" by bailing out the "can't fail".
Let's hope everyone is acting responsibly this time, because printing more
money
only adds "money" to support the "value", if everyone agrees to "keep" the
value
of "money" the same in the economy. Otherwise, we get "inflation" that will
devalue money again, and that won't help. Hyper-inflation is being predicted.
You can hope for privatization to work, but there are no guarantees. With a
baseless "money", we can, actually just print like mad, all we want to
employ as
many people as possible to do as much "work" as we can find to do. Since
everyone is working, and we are getting useful results, does it seem wrong to
"print money" to employ people to work? We did this for the wars...
Once we are done with a "work" program, how do all those people continue to
live
in the economy? What is happening with the Space Shuttle program? An answer
might be that we just keep printing money and let them "live". But that's
what
everyone calls socialism and historically, it hasn't worked. Food stamps,
unemployment, and other assistance programs are argued to create socialistic
behaviors, but how do we decide the moment that a person or a project deserves
to fail? Do we have to judge it as "bad", or do we need to declare it "okay
to
fail"?
Practically, we can argue and discuss about gold or silver backed currency
till
we are blue in the face. In a resource backed, currency based economy, if new
people are to be employed, someone else needs to take a pay cut, spend some
money, or die so that the new person can be paid some money. If more
"value" is
created in the economy with new products, then the price of other items have
to
decline for that other value to be accessible for purchase. If you have to
plan
your business to continuously reduce prices, how far can you go before you
can't? What does that do to initial prices and who can purchase? The Fed
controls available money, hoping to manage this appropriately so that printing
only should happen when new economic value exists.
Getting more of the "resource" such as mining gold/silver, would be like
"printing" money because once you add it to the economy, there will be more
available and the worth of the existing will likely decline unless there is
additional "value" added to the economy to make the "gold" harder to get.
This
is why some people believe the Fed is okay as long as it's managed
appropriately. It is cheaper to print money then it is to "mine" gold, and
gold
and silver are useful resources, where as "paper" is manufactured from
renewable
resources.
With the Fed in operation, the "annual cost of living increase" in your pay
check was about equalizing your "money" with the "Fed" printing rate so that
you
didn't have to take an effective cut in pay because of the inflation being
created.
The Fed prints enough new money to take "growth" into account, based on what
it
can track. The problem was that too much "money" was being loaned out and the
"banks" had stacked their own debt at more than 10-to-1 against cash on hand
with loans because of lack of regulation. Thus the economy was larger than
the
Fed could "perceive" and we didn't have enough "cash" to cover such risky
behavior. And yes, the risky behavior should not of been happening either.
It's important to learn how it all works so that we understand that
privetization is possible, but there are countless circumstances that don't
always make it economically possible. Money, today, is a vehicle that can be
used for a lot of things, and the misuse of it, as we've seen, can destroy the
economy or damage it severely.
The X-Prize, for example had very view participants because there wasn't any
"real" prize except recognition, and ultimately the "knowledge" gained from
participation.
Where are all the interests at really? I think there should be lots of
interest, but I sure don't see anything that would suggest that there would be
10 space flight companies making regular trips into space by 2020.
This is way off topic for this group...
