First attempts to create a low pass filter (LPF) for 2m (144MHz through 148MHz). Video is a bit long and in detail but it does give a great sense what's involved with creating these filters.
I am aiming for a low pass filter in order to filter out spurious emissions of my 2m transceivers. But a band pass filter would work as well. During the measurement I saw that the "filter" suppresses some lower frequencies as well. That's where my choice of words came from. Thanks for watching.
The title of the video says Low Pass Filter but in the video you are talking about Band Pass. Which one were you actually aiming for?
