Hellow to every one yea i have also tested this transmitter this works good,but basic problem with this transmitter is the range and the sound quality which is not up to the mark if some body is really interested in making good FM transmitter go for 4 Watt FM transmitter. After making this transmitter u will feel like u have made something

its like a small radio station with a huge range of 50 KM in open space

do u know source of silver coated wire (Gauge?0 also RFC1=RFC2=RFC3= VK200 RFC tsok
TR1 = TR2 = 2N2219 NPN
TR3 = 2N3553 NPN

TR2 2N2222 or 2N2219 or BC337-25 NPN transistor
TR3 2N3553 or 2N3924 or BFS22A
No need of using silver coated wires our simple copper wires with the given diameter, can be used.
choke VK200 can be obtained from a Radio shop
or

http://www.rfparts.com/choke.html

if u do not get this component dont worry

RFC is a radio frequency choke it is a circuit element designed to present a high impedance to radio frequency energy while offering minimal resistance to direct current. RFCs are frequently used in series with power supply leads both to keep RF from coupling via undesired power supply paths and to prevent power supply components from paralleling undesired impedances across the RF circuit.
so if u want to avoid this in your circuit u can.
I hope it will be usefull.

Hey guys, my name is Andy. I have tried to build that transmitter and I think I need a little help as it's my first project. The 9v battery at the top, I can't understand where the 2 wires should go ? Has anyone actually built one of these ? If so can you pleassseeee please e-mail any photo(s) to me at NORRIE3699@HOTMAIL.COM I'd really really appreciate it thankyou !

I am also well into making money and have my own site forum www.money-ideas-forum.com It has just started hence the low number of registered users. Please come along and join in the money making help !
