Ah, I got it. I will look into that.
Btw, generally speaking, how is the efficiency the spectrum sensing in gnu
radio? I use the spectrum_sense.py to sense 9M a step and generate 256 bins
which takes me nearly 1 second to sense 1M. It is really slow...

Depending on the frequencies in question you can use several COTS amplifiers
