Most of the space got filled with the fluttering motor-boat effect.
Probably the motor boat effect was due to the carriers not operating on exactly the same frequency.
This motor boat effect also should be present in the noise level in receivers of nearby, unsynced AM systems with the receiver volume turned up a bit, and with no modulation of the transmitters.
Once the carriers are exactly synced, then the audio fed to each transmitter needs to be synced in the time domain, as well as having the same negative-going and positive-going peaks, and modulate each transmitter in the same audio phase.
