Hi there, i research some rf stuff and did it so far with a radio
scanner and a soundcard, but lately we have aquired now a fine
hardware with the right boards. So i wanted to start to port this to
gnu radio.
It seems to be a miller encoding on top of the FM/FSK signal. I
didn't find so far
especially the basic concepts aren't that clear
for me.
Also i think it should be done off-list and presented the results and
howto to the list because i will have to ask some more questions i
think :-)

Heya there,
i tried to install gnuradio now under osx and had built all
dependencies incl libtool etc according to the tutorial using
darwinports.
Now when i go to checked out directory and run ./bootstrap
thats what i get:
./bootstrap
/opt/local/share/aclocal/audiofile.m4:12: warning: un
" can easily be corrected; again see the
install guide near the end.
Good luck! Let me know if this works. - MLD

Hi there,
well i managed to edit the files to rx my frequencies and file_sink
it to a file and use tx to resend it. But the resulting signal looks
to "soft/analog" so my keyboard receiver does not correctly interpret
the signal. Is there a way of reading from a wav file and fm_tx it?
Or i
Hi List,
well i got much further and was able to gather the signal and am
shure that it is a Miller encoding (Also known as delay encoding). So
i like to build now a parser/decoder for that protocol. As far as i
understand gnuradio, decoding blocks have to be in C C++ right? Is it
possibl
Sorry for that, shure i would be happy to provide you some
information i am currently stuck anyways in developing a decoder
because i am not the best in signaling stuff :-)
Ok well i know that the signal is Miller encoded (Aka Delay encoded)
On this website you can see a short description:
Hi there,
well gain i like to ask a short question. I did try to record some
signal in 27mhz. Its FM based.
I did it like this:
1st i modified usrp_tx that it saves the recording into a file called
audio-0.dat
/usrp_rx_nogui_to_file.py -f 27.195M -g 20 -m FM (tried it with rate
32000 an
Hi there,
i did make some progess again but had to amplify collected audio
samples using modified usrp_rx_noguiy into a file. That was working
great before successfully resending it i had to normalize and amplify
the signal and
then resend it using fm_tx4.py. So my question is the followin
Hi there, i am trying to play around further with the tools in
gnuradio and was surprised that when i use
usrp_fft.py -f 27.195M everything worked as expected, but as soon as
i added the -W or -S to the command
nothing works anymore. Application seems to hand.
Does someone notice the same pro
Hi there,
fm_tx4 is sending the signal in a "loop". I did not find hte right
spot to tell him that he should only send it 1 or X times. Can
someone help me out on this?
Thank you again.
