rehan said:I have to tune receiver for radio control aircraft , freq: 72mhzFM.
2. Then after demodulation i should tune for max output or after IF stage i should do that .
3. the signal i am receiving is PWM so i canot adjust sine wave.
4. How to detect if ceramic filter is working alright because many times after crash of model the filter is faulty and it gives gittering signal output.
