This filter can suppress the signal between 88-108MHZ and has an attenuation of about 50dB or more.
The broadcast FM band stop filter is very useful to use with SDR, because in some areas, the broadcast FM signal is very strong, resulting in SDR Overload, resulting in very poor performance in other frequency bands.
If you see the image of the BCFM radio station when you increase the gain, it looks like WFM signal interference at other frequencies, you can judge whether this is the case.
This filter mainly filters out FM to prevent its influence on short wave.
The pit of this filter is relatively deep, and it will also affect the aviation frequency.
