C2 bypasses the first transistor's emitter resistor for AC to eliminate the negative feedback for the input audio frequencies thus increasing the AC voltage gain.
R5 provides bias current for the second transistor.
C4 provides a high frequency ground bypass for the second transistor base oscillation current.
right now i have a baby monitor receiver that has a carrier frequency from 49.83 to 49.89 Mhz 4 cahnnels being 20Khz apart
i know how to calculate my C5 and my inductor along with the audio amplifier resistors
but how do i figure out what value of R6, R5 to use
and does it matter what value i use for decoupling caps and C4 C2??
thanks for the help~
