Thank you for this great circuit. I've tried it back in 2001 and it's just worked perfect. I've searched for the website and was so glad that it's still up and running. I made a post on my blog and an instructable. http://idea-arabic.blogspot.com.eg/2015/11/fm-transmitter.html

Hi! I'd like to use the transmitter for remote switching.How to replace mic to send a switching pulse? I'm a teacher in the high school & I'd like very much to put forward this project for the annual competition for my students. Thank you Sir! Ashok.

I builded that transmitter to that PCB layout seen on that page. That little transmitter is very unstable, it drift 89.100 to 89.329, 229khz in 5mins! And FM deviation iss very slow, only about 5khz. So after that I builded smaller versio of that using junk SMD parts and with little modifications. I get it stability to 50khz/5min and deviation to allmost 100khz.
