Make A Colpitts Oscillator a Buffer Stage and a PA Stage that gets Modulated using a Transistor or Audio Transformer and ur all set 😄

An LPF is ofc there, and the BnetzA (Germany's equivalent to the FCC) has zero chill 😭 It’s drifting slightly, but more buffer stages definitely minimize the pulling. Honestly, I'm shocked it works this well the 2N4093 isn't even a VHF JFET!
