Years ago I ran a plate modulated rig which had 5 watts of carrier and
about 300 watts of audio (W6QYT system) , it was very effective. As for
inverted audio, one of our bunch experimented with that too, it was
supposed to make tuning a DSB signal easer if you didn't have a
selective receiver.
Drake TR-7 radios use A3H which is carrier plus upper sideband.

One of the main objections to AM is that the mode requires twice the spectrum
space as SSB. One of the strengths of AM is that the audio from a transmitted
signal is recovered perfectly because the carrier that produces the RF/Audio
mix is sent also. This makes the decoding or detection of the a
