I would like a narrow bandwidth just like a notch filter, but I want that signal to pass not be stopped. The bandpass filter is not narrow enough. The frequencies in question are for the 1750 meter band. 160 kHz to 190 kHz. I would like it to be variable so as to be able to dial in on a specific frequency.
I would like to use an active filter rather than an LC type. I am just not seeing what i am looking for when I searched the forum or search engines.
I am very interested in the 1750 meter band operation. Any help thanks.
