Hi, sorry for not saying, but I'm based in South Africa.

I Got it off the net. I'm sorry to say, but SA is a bit behind when it comes to electronics as a hobby.
the problem is, my local electronics store doesn't supply the BH1417F like in the silicon chip magazine. But still, it looks like a nice circuit. I don't want to be a nuisance, but you don't perhaps have schematics of a simpler transmitter that is made of commonly availible parts.
As always, thanks for the help to the newbies like me.
Although I do find Colin's work very easy to follow
u said "use a black one" and thats rude! Ppl like u must banned from these kinds of sites!
@nerous, u may try Bc547,2n2222a,2n3904 for low power fm transmitters and 2n3866,2n2219a for higher power transmitters,
good luck
I am a white-skinned person. Is it rude to call me "white"?
Is it rude to call a Chinese person "Oriental"?
I went to China to find a UTC datasheet for their S8550 transistor. It shows no skin colour so it might be purple instead of black.
It might not work as an FM transmitter because some of them have a gain of 1 (like a piece of wire) at 100MHz and won't oscillate at frequencies up to 108MHz.
My FM transmitter is fairly low power so a BC547 will work the same as my 2N3904.is BC547 better than 2n3904 for low power RF amplifier? And I have seen the fm transmitter you have posted using 3 or 4 2n3904 so how many long it could be reach?
When my transmitter is close to my cheap radio then it appears at many points across the entire dial.
