Arduino 433MHz Transmitter

Hey, you have to create that oscillation not use alternating sorce to simulate it (yes that one with 433 MHz) !! For RF transmitter using a single transistor, I think you cannot simply simulate this one here because it is simpler than the real transistor. FM modulation will happen as a result of the changing internal capacitance inside the transistor which is affected by the applied voltage on the base. Now we come to the main part, your oscillator in the collector part will be made of simple oscillating circuit, i.e. an inductor and capacitor in paraller. It will be tuned to give 433 MHz, And since it is in series with transistor of varying capacitance you will achieved this effect of FM signal.

I dont know what you are looking for, looks like you try to modulate it in frequency. However, before any nodulation can be simulated, you should start with the oscillation! Check this and see if L and C you can make realistic. http://everycircuit.com/circuit/6510171064107008

Ich glaube, dass diese Sender nicht viel mit FM zu tun haben. 433.92MHz an entspricht dann einer 1 und aus einer 0 oder so.

So ich hab jetzt auch das mit dem LC Schwingkreis gemacht, bin aber nicht so sicher ob es das ist was du meintest...Bei der max. Amplitude schwingt er dann bei 433Mhz. http://everycircuit.com/circuit/5832344761270272
