I am trying to use the cordless mic cktry as rf module.
Fot that i remove the mic as well as coupling capacitor and inject pc com port txd signal via max232 through the attenuator which is variable i adj. it for min./ sufficent voltage.
and insert the receiver in to pc audio-injack for test .
After some adj-ment i get the same waveform as at txd pin.
AS the output of receier is very low .
For that what can i do.
It is just matter of waveshapeing ?
Any guidline for the same
