AM MAX II DSP is an AM transmitter. produce the AM waveform at a low level and amplify it to a higher power level without distortion. The main disadvantage of high level modulation is that the audio modulator’s power must be half that of the final transmitter, not too tough for our low power kit, but try to imagine the amplifier for a 50, watt AM broadcast station.
