I know "suer-regenerative" is quite simple circuit but has very high sensitivity. Long time ago, I've seriously studied super-regenerative at 2.4 GHz and more for practical application. ( I like super-regenerative but not regenerative..) Realization of super-regenerative by vacuum tube was an assignment for me since I was a child. This time I made receiver by Acorn 955 tube made in 1944, during WWII.

Basically super-generative is a "quenched" oscillator and its receiving frequency can be observed by spectrum analyzer. This also leads to one issue, spurious radiation and we have to insert head amp for isolator, or we should not connect good antenna. I received aviation communication but it is "spontaneous" and I could not make video...

On-board variable capacitor can tune receiving frequency from 113 MHz to 132 MHz, mosty covering "air-band".
