Two oscillators, one adjusted to 7.02 MHz, the other to 7.20 MHz, together form a stereo sound carrier generator for 13 cm ATV Tx. Both oscillators are built identical and the outputs are simply put in parallel.
The two oscillators, built on vero-board, together with a 7809 based power supply (so my circuit is fed by 9 Volts instead of 12 as drawn above). The positive power supply must be decoupled to chassis ground (for example a small electrolytic capacitor placed in parallel to a ceramic 100nF capacitor) for each of the two oscillators separately and of course, two 100nF capacitors at the in- and out-put of the 7809or 7812.
