Here is another attempt at me making a transmitter at about 433Mhz. Eventually I'll tune L1, C1, and C3, but the major problem I have here is that I took an idea of tapping the signal off the oscillator NPN emitter instead of the collector. When I run the simulation I get a rather choppy waveform (see attachment) showing no real modulation. If I strip everything to the right of the 5p capacitor except the battery (of 5VDC), then I can probe the voltage of the NPN collector and a clean waveform will result, however the voltage reading is maybe 12 at most which won't be much for transmitter distance.
Rather than me upping the voltage, what else can I do to fix this? Is R3 and L2 and C4 and Q2 wrong? I'm lost.
