I made a rf transmitter that transmits either a 1 or a 0. I now need to make a receiver for it so I can send binary data. How would I make the tuner? Would a lc circuit be accurate enough to only pick up 1Mhz signals? My transmitter outputs a square wave when it is a sending a 1 and doesn't oscillate at all when sending a zero.

 

Are you using a "Jameco 1 MHz Full Can Crystal Oscillator" for your transmitter, by any chance?

Experimenting is usually a good thing to do, but when you start transmitting radio waves without being careful of the broadcast frequencies, you run the risk of messing up your neighbors radio reception.

You would be better off getting a set of RF transmitter/receiver boards like these -

These do much of the detail work of sending and receiving a radio signal, and they do it so it doesn't interfere with other peoples radios.

I would suggest using these for the actual RF communication part of your project. There will still be plenty of design work for you to do in getting these built into your circuit.

 

Yes I might look into those, but to increase my knowledge I would like to build a working receiver. How would I build the lc and amplifier circuits?

 

Hey actually i m from electronics department .His thought is correct .but how do i give good solution to you? I think you may be use any oscillator circuit after that you have rectified you error.i don't know the correct solution you have tried to chose this. otherwise using some ripple capacitor.
