Hi,


Yell really loud?


Seriously though, you're asking a lot here. Maybe ask one part at a time like start with the theory?

suggest some reading material like the ARRL handbook for amateur radio operators for a start
google searching will lead you to many sites telling you all you want to know

once you have done some initial study, then start asking specific question to bits you didnt understand
thats how most of us learnt about various subjects

cheers and happy studies

Best way to do what you ask is to buy a kit, study the info, especially on the modulation ic, then build and test it. All for under $30 AUS.(p.s. I don't work for jaycar).
Jaycar Electronics - Better. More Technical. - KJ8114 - mini mitter fm transmitter. I'm sure there is something equivalent where you are.

hi ,
actually i know the basic theory....
but the problem is iam not able to make it practally...
the only thing i can do is an oscillator. , microphone and the amplifier... the remaining iam not able to do...

the main thing is i want a simple ckt.. so that the components are readily available in the market/.....
