hello everybody :
I am air band electronic enthusiasts. This is I do super-regenerative receiver .
25 km from the airport in the city center, 7th Floor, indoor.
The sound is very clear.
Here is the circuit diagram and my Radio.

Reminds me of a bug detector I wanted to build.

I seem to recall that wiring layout in a superregen was critical. Not to be critical, but wouldn't that 'bird nest' be a source of oscillation?

This circuit is an emission source can interfere airbandradio on the plane.

The seemingly simple super-regenerative circuit.In fact, the wiring is very important
Routing is the key to success.
I chose the the finished product from taobao.com (China) .

Just don't try to bring it ONTO a plane. Looks too much like a homemade remote detonator.

it would interfere with airborne radio

I tested at the airport
Within 10 meters it would interfere with airborne radio
So don't try to bring it ONTO a plane
