Review on 📻 Enhance SDR Signals with Distill:FM Barebones - Efficient Broadcast FM Bandstop (Notch) Filter by Nancy Gracey

I needed a slight bandstop so our local VHF stations don't clog the front of my spectrum analyzer when using a small LNA with a pre-compliance test antenna. This little filter worked great. I used the tracking oscillator and spectrum analyzer to check the frequency response and the distillation filter and everything was fine. Out of curiosity I used NanoVNA to do the same check and indeed the S21 parameter matched exactly what I had seen with the correct SA. In any case, this little filter works great and, for those who care, does not interfere with aviation VHF. Chic! All that being said, there is a small metal-bodied variant of this filter sold as the Flamigo. It has exactly the same still filter but with a small metal box. I like this variant a little better, if only because of the mechanical protection. And the same company makes AM rejection filters that have the same form factor as this FM rejection filter. I tested the AM bandpass filter and it works fine too. Distill's bandstop filters work as advertised.
