This is the circuit Tom posted. I modified the tuning and regeneration controls. This one works if you have the components. The modification allows for components parameters variations and works with different JFETs. I made a couple of AF output stages for it.
The coil is detailed here:

This is the circuit introduced by tom with my modifications.
I gave the audio output a little boost with this pre amp.
This is the audio amp I am using.
The Audio Amp
2 watt amp. Connected the 5.6K resistor to the tap between the 3.3Ohm resistors.
