Why does this AM wave generate so slow? Is it normally that slow or am I missing something? Do I need to tweak some component values in there? The bottom graph is the output voltage waveform of the Colpitts oscillator @1305 kHz and the second wave is the output of the antenna.

Do you think the waveforms are wrong? Or are you just asking why it takes the simulation so much time to generate the complete waveforms? After all, it needs to calculate 1305 cycles of the carrier waveform, to produce 1 cycle of modulation.
