Same results here J
Also many months ago it dawned on me I could probably use the notch filter on a local/semi local FM BCB station that was just transmitting an unmodulated carrier to ‘uncover’ & hear the much weaker dx station on the same frequency. All I had to do was create a notch for the centre frequency & another two notches for each of the 19kHz pilot carrier sidebands.

That’s something I never thought of trying. I’ll give it a try next time an opportunity presents itself. Thanks Paul.
