repeating pattern 171 Mhz

Post by bauli » Thu Dec 29, 2016 9:57 pm

hello to all members, I'm a newbie at SDR.

has anyone got an idea, what causes this repeating pattern at the spectrum?
I am using a special handyscanner antenna for the selected range of 171Mhz.
I'm thinking of some kind of distortion, but cannot locate it.

Yes this is probably just noise generated by some nearby device, or perhaps overload from strong BCFM stations.

I'd try turning off nearby electronics to see if it goes away.
