High frequency noise

I have tried my RTL-SDR stick with our software and it worked great but I found out that there is a background noise with a very high frequency. I also tried the stick with SDRTouch and with that app this noise is not present. I don't know if that noise could be the rds data or other overlaying informations or maybe only a filter is needed.

Thanks Thomas

SDRTouch and RF Analyzer use the same driver to get the signal from the RTL-SDR. I could imaging that SDRTouch does a bit of averaging to smooth the display of the FFT. RF Analyzer also has a setting for averaging, maybe give it a try?
