In this video, I am using various components of my homebrew spectrum analyzer project to analyzer the characteristics of a 40 m double tuned bandpass filter. My spectrum analyzer is based on Scotty's Spectrum Analyzer:

There's a lot of information on the web on these filters, for example here:

The first part of the video discusses the filter itself. The second part of the video is a demonstration on how to calibrate the system and how to perform the experiment. The video concludes with showing the effect of changing the coupling capacitor value of the tuned circuit.
