Thats a good schematic. The oscillator is buffered properly and the output it tuned to reduce harmonics. Be careful to select the correct video polarity at the input and sound carrier frequency as it varies from one country to another. It will suffer some amplitude modulation on the sound and it's quality may not be perfect but it should be adequate.

Hi Zsolt
sending some circuits . certainly . but with what method ? would you like that i send you an Fm transmitter via a PLL or perhaps a miller modulator or perhaps a varactor modulator ? which one exactly ? or perhaps you're interested in all of them ?
For instance this one is a miller effect FM transmitter which is good ! ( in fact it's out put will deliver both AM and FM modulations !! ) . take a look here please :

Sir, can you pls send me one varactor based and one PLL based FM transmitter schematic? I've made two miller based FM transmitters but they suffer a lot frequency drifting.....
