The Odd-to-me SW regen update.

The original circuit and the fix. 
I'm not a big fan of the LM386. This is my AF stage. NOTE: Use a 100K pot with the receiver to prevent overloading the detector.
Here is the circuit I built. I'm using slug tuning and diode tuning. I'm using a 9 volt supply. The posted version used a 5 volt circuit.

Here is the modified circuit with the AF amp.
