super MINI FM receiver

I never publish this circuit before but i will now.

It is simple super regenerative synchro receiver.

Is build with two RF transistors of which you can use

BFR 91A

S9018

2SC839

BF199

2SC3355

or any other for VHF range , also you may try with two 2N3904 ~  ft 300MHz

I use C839 i have at hand.

Layout of circuit is very critical which means that oscillator should be shielded with

PCB area ground like with soldering islands .
