FM transmitter

I found this FM transmiter "http://www.uoguelph.ca/~antoon/circ/fmt1.htm"
I want to know if I can replace the microphone with a line-in.
 
Hi Shadow,

Yes, you should be able to eliminate R1 and the electret and feed it with line in. You may need to put a pot. in line with the line in though to prevent overload.
