Hello , with gnuradio , I was able to generate (following the tutorials  
on the net ) Narrow FM receiver that works with a USB RTL2832 . Now I’m  
trying to figure out if I can manage to simultaneously monitor two  
frequencies . Some of you can tell me if it is possible to achieve this  
with a single key , perhaps by scanning continues between the two  
frequencies that would be set manually.
