Hi Marcus,
I just found the problem. My device only has one channel. I deleted
all the 2nd channel stuff and the spectro_radiometer is working great.
I’ve got to find where the data is going, but I like the many features you’ve
added.
Cheers

Dear Martin Braun,
Thank you very much for such quick response, I really appreciate that. I
wish to clarify several things:
- By "Differential modulation", do you mean that in my case, I should use
Differential Quadrature Phase Shift Keying (DQPSK)?
- For the more sophisticated option, can you g
Thursday is the org application deadline, not the student application
deadline. So, plenty of time.
As for a project idea, I'd be careful about scope and relevance. You've
suggested a statistical toolbox, and the HTML GRC. I would pick one, and
then flesh out the project idea. Both projects you've

Glen,
as the GSoC guy I have a couple of comments. But first of all, I'm glad
there's interest from more radio astronomers in GNU Radio -- as Marcus
points out, there's already a couple of RAs using GNU Radio, and you'll
find a bunch of nice experiments out there.

Looks like you're not resolving the pi/2 ambiguity. To do that, you
either need something more sophisticated, or differential modulation.

Dear all,
My name is Minh T. Pham, and I'm completely new to GNURadio. I want to learn
more about QPSK modulation and demodulation using GNURadio, so I started
reading through and follow the "GNURadio Guided Tutorials". In Tutorial 7:
PSK Symbol recovery, the model utilizes Constellation modulator
I'm running the live_signal_detection. I replaced the rtlsdr_source block with
a signal source block. When I run the flowgraph I get
"attributerror: Module object has no attribute 'signal_detector_cvf"
I tried deleting and reinstalling all the dependencies before installing
gr-inspector
Thank you Marcus :) It's solved.
Have a nice day

Hi,
I remove all osmocom files and reinstall gr-osmosdr with libbladerf
(previously installed) but now I have other error:
FATAL: [bladeRF source] Failed to open bladeRF device libusb:instance=0
Any ideas what there may be wrong?

Hi Kartik,
ha! Sorry for mixing this up. Yes, in that case, you'd be the GSoC
participant, not the mentor :)
I've pinged the right people. Hopefully we can get your account going.

Hi Dirk,
Well, if you have a let's say 2 kHz uncertainty in the frequency of your
pulse, I'd really start very simple. Looking at your plots, I think we
can sufficiently suppress the noise simply by low-pass filtering:
* Use a Low Pass filter (real taps) with a cutoff of 1 kHz – that will

Hi Tellrell,
Which flow graph are you running?

Hi Dan,
This is something I fully do on the side (evenings, weekends) in order to
help an animal rescue charity. So very much a fun / volunteering effort and
I hope to build something they can use in anger. For my dayjob I work in
software/robotics but radio is still very new terrain for me.
