Hi,

I have found an AM transmitter diagram on this website: https://www.circuitstoday.com/am-transmitter-circuit
And I would like simulate it on Ltspice for a school project. But it don't work. I get this:
It seems that the oscillator don't oscillate and there is only my source's oscilation. Maybe it need something to make starting the oscilations ?

Thank
 

If you 'skip the DC bias point calculation' it will usually get an oscillator going. Another option is to use a fast ramp for the supply voltage rather than a fixed DC voltage.
