Hi all,
I have noticed that when enabling the DAB notch filter on my RSPdx under SDRUno, there is a wide 'hump' in the 430mhz area of the spectrum. see attached picture.
The 'humps' are wide, a few Mhz and there appears to be a few of them around 430Mhz land. When the DAB notch is disabled, the humps drop right down.
I do seem to be seeing some noise on the 70cm band recently, is the DAB filter just allowing this noise to come through do you think?
