Hello friends,. can i ask you what proper diameter and number of turns in the coil of Collector and Base (**broken link removed**) if use 20 pf variable resistor in order to adjust frequency from 88Mhz to 108Mhz. Thank You.
 

20pF is a capacitor, not a resistor.
In the video the coils are not coils but instead are simply half-loops of wire, a yellow one and a white one. The distortion is VERY high.

There are hundreds of circuits if you go to Google Images and enter: FM regen radio circuit
