What is the source of interference?

[tim.krause]

I've just been using the BladeRF 2.0 A4 and found some interference. The antenna is a 20cm monopole.
To demonstrate the interference I have modified GQRX and wrote a python script to control GQRX and take a screen shot at the frequencies that this interference is most noticeable. Then the screenshots were compiled into a mp4 video and uploaded to my Google drive.
Here's a link to the video file on my Google drive.

I live within 200m of a cell tower. Could this be the source of the interference?

Are any of you BladeRF users experiencing interference near cell phone towers like I am? I just ran a Python script to capture the frequency spectrum via GQRX, and the video sweep shows very clear interference bars in sensitive frequency bands. At a distance of 200m, the transmit power from that tower is definitely saturating my SDR. Should I switch to a directional antenna to reduce the beam pattern towards that cell phone tower?

Yes, it's quite possible that the cell tower within 200m of your location is causing the interference. Cell towers can emit signals that interfere with nearby radio frequencies, especially if your antenna is picking up a wide range of frequencies.

The source of interference can vary depending on the system, but common causes include nearby electronic devices, overlapping wireless signals, damaged cables, poor grounding, physical obstacles, or faulty equipment. Identifying when and where the disruption occurs usually helps isolate the exact cause. More related content is available at https://oscarspins.com.es/
