I Have this setup
SDR(fc)
-> 'Frequency Xlating FIR Filter' (Low pass, Center Freq: 100k)
-> Resampler( 5M/100k)
-> 'QT GUI Frequency Sink' (Center: fc+100k, Bw 100k)
And parallel with QT GUI FSink,
-> 'Log Power FFT' -> Python (Peak detektor)
My problem I have is the read out from 'Log Power FFT' starts at 'fc+100k'.
I would like it to start 'fc+50k'.
Can I use 'Frequency Xlating FIR Filter' again and lower my frequency starting
point?
Like this parallel with QT GUI FSink,
-> 'Frequency Xlating FIR Filter' (????)
-> 'Log Power FFT' -> Python (Peak detektor)
What kind on taps do I need if this is possible?
