Hello thats an off hand description.
Would you please explain it in some more detail, I think for that purpose coil and bjt info is not required.
thanks..

Second stage is RF signal amplify + filtering and pulse reforming[/quote]
second stage is having bandwidth of 1Mhz only so it can handle high frequency
if we invert : inverting and non-inverting pins of opamp then we can think this as comparator with hysterisis.
first stage is antenna matching : tank ckt frequency selection, transistor is front end of receiver(super-regenerative receiver).
