[baudline] setiQuest articles,

[Gerr]

Hi Sigblip,

Just a short note to let you know I love the setiQuest articles on the
baudline blog. A very in-depth discussion of advanced baudline usage,
definately worth a read.

Thank you!

Thanks, glad you like them. My favorite setiQuest reports so far have been:

http://baudline.blogspot.com/2010/06/setiquest-pulsar-psr-b032954.html

All three of those have a modulated signal in them. I've also
attempted to make a HOWTO tutorial:

It needs more work but I'm not sure if I should add more basic DSP
theory or higher level baudline tricks or both?

I don't know why but nobody seems to be using baudline over at the
setiQuest forums. The situation is sort of sad. So if you like using
baudline and you like searching for weak signals and you would like
free access to some high quality radio telescope data then definitely
check it out. Who knows, you might learn some Astrophysics and
advanced DSP theory.

Maybe people do (I do) but they have nothing to add (I don't) to your
already very deep and detailed analyses :)

New setiQuest blog report for the Deep Impact satellite telemetry
data. It has a curved drifting random walk, modulation, self
similarity, and a "surprising discovery that gets even stranger."

The SETI Institute did a re-observation of Kepler-4 and uploaded a
couple of data sets. Data from the original observation had an
interesting drifting FSK signal at a low baud rate. I analyzed this
new data and found another modulated signal in roughly the same
position relative to Hydrogen. This could get interesting:

New Lagrange-4 setiQuest blog report. Analyzed the L4 1420, 2008, 3991
MHz datasets. Many interesting signals, some with modulation
characteristics. Several demonstration videos too.

A quick signal analysis of the NASA Voyager probe data. Found the
Doppler drifting signal in the setiQuest data with baudline's Auto
Drift feature.

The SETI Institute has spotted the NASA Voyager 1 space probe again with the Allen Telescope Array (ATA). I analyzed this new Voyager 1 data with baudline and blogged about it:

The spectrogram image below shows both X & Y linear polarizations as green and purple. Can you see the drifting weak signal?  It is weaker this time around.

I did a detailed signal analysis of the GOES-11 weather satellite dataset and posted it to my baudline blog.

The setiQuest GOES-11 dataset is a smorgasbord of signals, mirror aliasing, and the return of an old mysterious friend.  Baudline's new IQ display was used to classify the many different modulation types.
