Very well done indeed. I am working on a CW decoder project, with an ESP32 MCU doing the signal processing and decoding, but wants to clean up the signal before it enters the ESP32. If anyone wants to join in they are welcome, just write a comment here and I will know.

Dear OM, any news on this? I’d like do build a cw filter like yours for my pixie trx. Unfortunately I’m can’t put together the code from your hints. Publishing your code would be highly appreciated! 73

Well done! Have you compared its effect with a 500Hz quartz filter? In any case, the main advantage is that it removed this characteristic hiss.

Based on -3 dB point, this filter's bandwidth is narrower than 200 Hz. But normally, I can say, it is 300 ~ 400 Hz width. check 1:30 and 2:15 .

It works well, will you be sharing the code and circuit?

I don't have any plan to open my version, but I added some hints in the video clip's description. I hope it helps you.

What's the reason for not publishing the code and helping fellow hams out? The code is freeware anyway...

Well, I think, it would be better for me to open the code if I use it commercially or publicly. But I haven’t yet. Anyway, I am thinking about that(release the code).
