based on your tutorial, i manage to work out the circuit just that the frequency was unstable ~
if i send a frequency of 433Mhz into the transmitter, will it be able to receive the same amount of frequency or an amount near to 433Mhz frequency over at the receiver side?
The RF frequency is done entirely in the modules, nothing to do with you - they accept low speed data signals, and the receiver outputs a 'similar' (not the same) data stream - which is why you need Manchester coding or similar.
i have a little problem with the circuit
i followed the hardware page and patch up the circuit,
however the circuit is unable to reflect any wave form..
no signal have been receive at the receiver end..
what might be the problem? is there any simplified version??
i had upload the board print screen
i had added 74LS14 ic in both board, but both can't work..

i wonder, what did i did wrong ~
thanks so much for your help bro..
initially it works on the breadboard but on 2nd try it failed..
i am pretty sure it's the receiver problem..
however i am not sure, what went wrong..
i tried upteens time but it just don't work..
The modules are really pretty foolproof, you connect them up as the datasheet says, and they work - it's as easy as that. I built my tutorial boards on stripboard, carefuly removing any unused tracks or portions of tracks, and they work perfectly.
What signal are you feeding to the transmitter module?, I presume you are aware that the modules are AC coupled?.
