This is so weird.
I build this simple bpfilter.
I used t50-6 amidon.
I want it for 18.1 Mhz.
So, in spice its perfect with either 3300pf and 24nH... Or 2200pf and 35nH.
(2 or 3 turns, inductor).
I tried both.
As you se it works over 18 Mhz in spice but then i build it for real the bandpass filter is 10Mhz.
What happens?
Whats going wrong here?
