Perhaps you accidentally turned on ESSB?
Tap the Config menu, and find TX ESSB. It should be set at 'OFF 3.0'.
Pressing '1' turns it on and off.

Subject: [Elecraft] K3 50MHz tx distortion
My SSB signal on 50 MHz is excessively wide and causing problems for
other users therefore I am seeking any assistance in curing the problem.
Adjusting the mic gain or the comp level has no effect on signal width.
The power supply voltage is stable and only varies by 100mV from standby
to full output. Examining the signal using the internal 2 tone test
revealed severe IMD at full output but dramatically cleaned up when the
power was reduced to 50W ( -3dB from peak).
I would appreciate any guidance on where to look next or if anyone has
experience of this what effected a cure.
