C6 tunes my schematic to the radio frequency you want. C13 tunes the output very broadly because the low impedance of the antenna loads down the tuned circuit. If C13 is peaked at 98MHz in the center of the FM broadcast band then there is still plenty of output at 88MHz and 108MHz.
Does this mean that i have to tune the L2 C13 pair to be at 98MHz?
Btw, if i'm connecting the FM transmitter to lets say another system such as PC or IPOD via audio jack, do i need any isolation on the audio jack side? usually how do people do isolation for audio? thanx a lot in advance!

Isolation from what? Snakes? Racoons? Elephants?
An audio jack has a signal wire and a ground/shield wire. Both are needed. Stereo has two signal wires.
hahaha, i was thinking of prevention measures to isolate 2 systems from one another just in something goes wrong like with one circuit the other would not be affected...nvm me haha... btw, how do you tune it to 98MHz??? did you use your sony walkman to do that?
