I just noticed something else: The USRP sample rate is set to 500kHz, not 20MHz. So you are only looking at 2.5 % of the target spectrum! It is also possible, that there are just no signals in that particular section. Best, Sebastian Müller gse...@gmail.com PGP ID DC2AA3EE Am 13. Juni 2019 um

Hi Daniel, from what you tell us, I conclude this is not an issue with gr-inspector but rather with generally receiving signals. If you use the QT GUI Sink for instance instead, you will see the same (empty) spectrum. I would recommend to try and get better reception, until you can distinguish

Hi Daniel, please remember to be specific when asking a question: "best way" is a bit ambiguous, and "I'm not getting a good result" definitely is insufficient for us to help you make things work better. What doesn't work sufficiently well? What happens instead? Best regards, Marcus On Tue,

Hi to everyone. What is the best way to receive all fm modifications. I'm usigin an B200 USRP. I think that putting the center frequency at 98M and a bandwidth of 20M is a good way,but I'm not getting a good result. The idea is to detect all fm center frequencies using gr-inspector
