Hello,

I’m trying to get a signal strength value (RSSI) from one specific  
frequency through a RTL2832 USB stick.  
I’m trying to do all this at an Raspberry pi, with Debian 7.

GNU radio itself is installed and it is showing a moving graph like it  
is supposed to do.

I would like GNU radio to give me a specific value of the signal  
strength at a centain frequency, which i can use in a python script.

Does anybody know how to do this through GNU radio or another program  
that might be more suitable for this?

I’ve allready tried FreqShow(Adafruit) and RTL\_power, but I couldn’'t  
get those to work…

Many thanks in advance!!

Kind regards,  
Stefan
