hi,
just created a rf transmitter and receiver project using the circuit
but i am not able to make it work here is the schematics that i have followed
rf transmitter
rf receiver
i have used 850k resistor instead of 750k resistor for transmitter circuit and
36k resistor for receiver circuit and also used 10nf capacitor ( .o1uf )
with 9v battery supply each for transmitter and receiver. and assembled it in a bread board
i am confused with antenna here (consider me a electronic newbie here )
i just took an insulated copper wire and coiled it and removed the insulation of one end and inserted into breadboard attached at the end of copper wire since the copper wire was thick and it was not going inside the bread board . please help me here . do i need to remove the isulation of the copper wire completely in order for it to work . how many winding should i make and what length of the copper wire should i use . i only need a 10 ft to 20 ft transmission
Thanks
Bob
