Hi Andrew,
yes you certainly can, but "GNU Radio is like a spectrum analyzer" isn't
really true – think of GNU Radio itself rather as a big box of nice
building blocks to put together one software spectrum analyzer, or a
DVB-T transmitter, or a radar, or…
What you can do, for example, is for

Hi Atif,
For frequency offset , a signal with (cos ((w + delta)t) + j sin((w +
delta)t)), where delta is the offset compared to original signal.
This can be achieved by creating a grc as attached. In this grc the signal
source (Tx) sample rate is fixed and in the sink (Rx) which is fft, the sa

Can I ask a silly question
Can you use gnu radio as a filter sweeper
Perhaps hack rf sig gen in harmony with rtl sdr to sweep a filter or preamp for
gain response
Since gnu radio is like a spectrum analyser

If you want to first manually correct, add a Qt GUI Range block, give it
the ID "dopplercorrection", and allow a start and stop of +- what you
expect. Set the default value to zero.
Then, add a "rotator" block, and put in the "Phase Increment" field the
value you want to advance the phase of
I am up to the stage of adding fft and scope sinks and resamplers and sliders
Need to explore the blocks
Curious about doppler correction

So, if you're completely new to GNU Radio, I'd recommend the "official

They start out rather smooth, and you can "stop" at any point (e.g. if
you don't actually want to learn how t
Thanks Marcus
I can now start learning gnu radio

Hi Andrew,
most SDR devices are most easily usable in GNU Radio with the "Osmocom
Source" block, contained in gr-osmosdr.
BUT: to get an gr-osmosdr with the AirSpy driver, you need to, in this order
1. Install GNU Radio and libairspy
2. build gr-osmosdr from source (Do NOT install it as bina

Can some one tell me please what I need to do to use my AirSpy Mini as a source

What do I need to install ?
The only other SDR I have is RTL-SDR and HackRF and Funcube Dongle
