Hello,
I am trying to run the "Your first flowgraph" example on the gnuradio Wiki.
This works fine when I run it from the GRC window, but when I try to run the
Python script that GRC generates, I get the following error:
from PyQt5 import Qt
ImportError: cannot import name Qt

Hello,
I am having trouble understanding the 'rx_time' field in the gnuradio
metadata. In particular, if I use the following code to unpack the metadata:

Hello,
First, congrats to Marcus and CCERA.
We are working at 21 cm (1420 MHz) and find that there are at least a few
pulsars not that far below B0329+54 (now called J0332+5434) in signal strength.
Indeed, one of the interesting things is that owing to scintillation
effects, th
Hi Fikrat,
The sampling rate must be twice the BANDWIDTH that you want.I don't
know much about
WiFi, but from the numbers you give, the range of frequencies you are
interested in seems to
span about 2.447 - 2.427 GHz = 20 MHz. The receiver users an analog mixer to
shift the frequency

Hello,

OS: Ubuntu 15.04
gnuradio: 3.7.5
The most recent step was to do a simple binary install of uhd-host and
gnradio using
> sudo apt-get install uhd-host
> sudo apt-get install gnuradio
All seemed to work
