[Discuss-gnuradio] swapping spectrum on the FCD

[Stefano Sinagra]

Hi,
I'm using a FunCube Dongle to FFT monitor the 69MHz if of my Yaesu FT950 ham transceiver.
Unfortunately spectrum is shown inverted, with signals 10kHz above my center frequency shown instead 10kHz below.

This isn't something new and I've seen I/Q swapping options in other instances.
Is there any fairly simple way to do it in GnuRadio when using FCD as a source?

Thank you
