USRP Radio Astronomy

GNU Radio
1

Hi,

Hope someone is able to help. I have gnuradio 3.1.1 on LINUX 7.10 and
have now managed to install pyephem from a previous problem. The fm
radio works fine but when I try to run radio astronomy I receive the
following.

Thank you,

Frank

Traceback (most recent call last):

I don’t know why you don’t have the FFT module.

When I run python on my system in interactive mode, I can:

Python 2.5 (r25:51908, Nov 6 2007, 16:54:01)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

import FFT

Which works just fine.

Do you have python-numeric installed?

You need package:

python-numeric-24.2-4.fc7

Installed on your system to get this package.

OK, I didn’t realize that it was deprecated.

Indeed, numpy has FFT support, and when I get a moment, I’ll fix this.

I had to take that into account with wsjt

I did this in wsjt.py

try:
from numpy.oldnumeric import zeros
except:
from Numeric import zeros

wsjt should work fine with numpy in the future.

Thanks!
