Hello,
Can a Q-multiplier be used as a front end BPF in a receiver?
I am talking about a wider bandwidth (200KHz or so) not a narrow one, like a regenerative detector.
Any ideas/circuits to try for 40m?
I would like to see if I can build a BPF frontend filter for 40m without coils with such a multiplier.
