Am TransmitterThis transmitter works pretty good if you use it as AM Modulator for an old Radio or just becasue u like AM. If you want to add an Antenna to it (Then it may broadcast 10-15 meters with a 6 foot long wire as antenna) you need to connect a harmonic filter to the output thats really important. It has been designed as modulator so in the final circuit I´d suggest to connect a 1mH Coil (that looks like the blue one on the circuit) from the hf out to ground. That will give you a range of 1m or so, and barely no "transmitted" harmonics.
