A while ago while researching FM Transmitters i stumbled upon a 1W FM transmitter, i think Veronika it was, that the description of which allegedly claimed that the frequency was a lot more stable than normal oscillators because they used 2 antiphase oscillators, and doubled their frequency. I'm still not sure why should it be more stable, maybe because if a normal Oscillator shifts by 1Mhz for instance at 100MHz, a 50MHz will shift only by 500kHz, or maybe because they are interconnected and if one shifts in one way, the other will shift in the other way, thus nullifying the difference. Idon't know just speculating here, Anyway i got a nice result here, the amplitude is a little wobbly but the frequency is stable.
