There's nothing 'wrong', but PyBOMBS does something else.
- The standard packagers can only install what someone has packaged
(usually quite outdated), and most of them only install to the system
- Installing out-of-tree modules doesn't work except for some, on some
packagers

Henry,
Yes, the data stream will be interleaved I and Q values.

Just a small correction, the samples from the
Hi Kevin,
great debugging!
The most likely place to look in is gnuradio/grc/python/Generator.py and
the .tmpl file in that same directory.
I'm not overly experienced with that, but maybe pdb is right for you.
A quick grep showed that the string "No closing quotation" doesn't occur
in GNU Radio's
Hi All:
Further info:
The issue seems to be with the single quote in the the .grc’s directory path,
“Kevin’s Programs”.
Looks like there needs to be an escape added before single quotes in file names
or directory paths.
If I move the subject .grc to another directory (i.e. not including “Kevi
Hi Daniel,
wow, you don't start small.
Really, for audio rate signals, your average laptop or desktop computer
will do. If you want to do awesome signal processing, the more CPU the
better, but don't go out and buy a new workstation assuming you'll need it.
Regarding your card: PCIe x1 is much fa
The Ettus B200 will be the preferred ground station for AMSAT's Phase 4
satellite.

Hi,
yes, what Ralph said is very true. The real strength of the USRP series
is it's high sampling speed. I own the USRP2, which is already around 5
years old and already did 100 MS per second, but it was rather expensive
at that time.
You can get much cheaper SDR hardware today such as the RedPi

The Ettus web site has a page about USB chipsets[1], suggesting some of
them can't handle the continuous streaming for SDR
Is this information up to date, can anybody else comment on this?

I do agree; but:
For example, if you have bad luck, the B2x0 might produce a third
harmonic of the oscillator it generates to mix up your signal; e.g. if

Broadcast radio & TV transmitters, police & fire repeaters, and others have
potent signals. If your system does not attenuate them, by using low-pass,
high-pass, or band-pass filters, the peak voltage at your analog to digital
converter may at times exceed "full scale". The resulting non-linea

Hi,
First of all, the USRP radios are kind of experimental radios, using them for
real ham radio operation on antennas will require filters and PAs. "Out of the
box" it will only be some proof of concept when you create a ham radio
application with it.
