FM Transmitter... 2 similar oscillators, showing that base-collector capacitance (original voltage controlled, here as different discrete capacitances) varies oscillator frequency. To start first oszillation push top button, to syncronize push the other button. Result is seen as slow changing lissajous figure

Wow, looks good. I'm an enthusiast, slowly self teaching myself how circuits function. I was planning on beginning a small project and thought a FM transmitter would be a good start, however when buying a resister I have no idea what it means by watt, for example I needed a 22k resister but it can in a 0.6 watt version and 6 watt version, if I use too big or small of a watt will it affect my circuit? I'm not sure if you or anyone would help me out, I didn't know who I could ask. Thank you.

@ manuthebet12345688 Measure power from simulation (V*I) for each resistor and then choose from standard wattage 1/2,1/4,1/8 and etc. big enough for the power measured.

Measure the voltage drop across each component. That voltage dross is multiplied by current to get the wattage.
