HI all, My name is Zen Chen , a GNU radio Novice and I tried to create an
account on the GNU Radio .org website to post my questions on the mailing
list however I could not . I am using GNU radio and Hack RF 1 to design a
power spectrum analyser and I am using the attached flowgraph to and python
script to give me the attached CSV file however , the results (FFT connect
to file sink) is to large to be contained in a single excel file . Is there
a problem in my GNU Radio Flowgraph?

Regards,
Chong Zhi
