The two pictures represent two schematics. One is my updated Superregen detector, and the other is my automatic station changer (ASC for short). When I connect the ASC to the green area of my superregen, the ASC works well, but the stations do not work well. In fact, I'll be lucky if I get 1/4 of the FM band. If I replace the tuning capacitor (in red) with the ASC, then the speaker emits no tone, but when I press the button, it sounds like the stations are changing, but nothing is actually happening.
If I didn't apply the ASC at all to the circuit and left it alone, it works nicely. It even works better when I add anything between 1 and 10pF across the inductor highlighted in green.
If I have to add a transistor to make the ASC to work, I will.
Because right now, for me to change stations will be somewhat of a pain because the most I can turn the tuning capacitor is about 10 degrees. Anything beyond that will cause me to miss a station. I wouldn't have this problem if my ASC can do it's job.
By the way, no parts are damaged, and the transistor I am using is 2N3903 (not 2N3904).
