if there can be any interest, I try to gradually go from basics (using
GNU Radio to introduce such topics as decimating, aliasing and the need
for low pass filtering) to more applied topics (of course FM radio
demodulation,
then POCSAG) and BPSK demodulation (Costas loop) and finally multichannel
analysis (Xlating FIR) in my lab sessions at
http://jmfriedt.free.fr/tp_sdr_eng.pdf
(or for the French speaking part of Belgium,
http://jmfriedt.free.fr/tp_sdr.pdf)
More challenging signal demodulations such as GPS and RDS are discussed
separately (eg http://jmfriedt.free.fr/lm_rds_eng.pdf &
http://jmfriedt.free.fr/sdr_gps_eng.pdf)

Hi all,
After the GNU Radio workshop at hsbxl two weeks ago, a number of
people of the Belgian amateur-radio community who where at the
workshop have shown interest in continuing to learn more about GNU
Radio.
However, one of the main issues we have noticed that we kind-of lack
a good "application" to use GNU Radio for, and -as we all known- you
only learn something by using it.
So, based on the idea used in cybersecurity training, I would like
to see if it not possible to create a number of "GNU Radio
challenges", either decoding radio-signals or creating an encoder
that produces a desired signal.
I know Ben Hilburn created the challenge (found on the GNU Radio
website) but that one is way above what most people are able to
decode (let alone people just starting out with GNU Radio).
Again, looking at the cybersecurity-scene: If you look at a website
like "root me" (https://www.root-me.org/?lang=en), it provides a
number of challenges with an increasing degree of difficulty, which
allow people to build up their skills step by step. And -as I see
it- this "step by step" approach is the most important element in a
educational project.
So, does anybody know if there are, or is anybody interested to help
create, more GNU Radio challenges that can be used for an
educational purpose, to provide people with a "learning path" to
really start to learn and use GNU Radio?
Are there people who use GNU Radio as part of teaching
radio-communication? What topics do you teach and in what order? How
do you get the students to understand radio-communication and GNU
Radio?
Cheerio! Kr. Bonne.
