The following is FM radio reciever circuit from:
**broken link removed**

**broken link removed**

I do not intend to implement, but Surprised by the way the two transistors T1&T2 connected.
The tuned recieved FM signal inter the collector of T2 and out of its base to feed to the audio amplifier
It is the first time in my life watching that stage audio feed from the base of the transistor
Can you help me understand the work of those two transistors?
Thank you very much

The receiver has an audio amplifier ( ICLM386 ), Selectivity though tank circuit ( C1 & L ), what we are left here is demodulation or detection of FM modulated signal, which is done by these 2 transistor... i.e. detecting changes in the frequency.... I know that much, there must be a lot about base capacitance & other stuff as well
