Can anybody help me in finding a Tuner circuit to reduce the frequency from 120 Mhz to 10,7 Mhz?

that sounds more like a frequency divider....
wha do you need it for?

So you just want a standard harmonic crystal oscillator?

Have a look at the Quartslab site for an example...

What are you going to use as the mixer?

Is it a level 7 dbm such as SBL-1 or the level 17 TAK-893?

Or will it be the tried and trusted BF981 dual gate mosfet?

ALSO Have a very good look at..........

An excellent site.
