Playing around with Tayloe Detector at 150 MHz

I had someone ask me whether my Tayloe detector board
   • Pyboard Radio - Updated Tayloe Detector  

Could work at 150MHz. I thought it might be interesting to have a go at that challenge starting with the band pass filter.

Here's devttys0's excellent BPF video with the "gimmick" cap

Here's an example of a double tuned BPF calculator

4:38 Undercoupling and overcoupling
6:29 Using toroids.info to build the inductor
7:47 First look on the spectrum analyzer - band pass frequency too low
11:07 Changed the resonator turns - second look
