radio station

I am using a Topping D10 Balanced with a Sabaj A20h and I just found something really weird, I am picking up FM radio interference but only on 3 separate volume spectrums, between -99dB and -85dB, between -3dB and -1dB, and at 0dB. Between -99dB and -85dB is the strongest, I can no longer hear...
