At Field Day I have observed a number of operators operating SSB. I have noticed that there is a great variation in skill when it comes to tuning the RX to an SSB signal. Sometimes I feel that the op has it tuned all wrong and I almost want to grab the knob. Maybe different people's brains focus on different aspects of the sound when they tune the RX. Some people seem to want to tune for the best balance between highs and lows, when the HI CUT and LO CUT would do a better job. When I tune the RX, I believe that I am not trying to balance highs and lows, but rather trying to find some kind of harmony in the sound. If I were tuning in a piece of music from an AM BC station with the radio in SSB mode, clearly the harmonics of a musical note will not be harmonious if the radio tuning is off. If a voice is used for singing, it is like a musical instrument. If the voice is speaking, I believe the harmonics are still at play as with a musical note. This leads me to speculate that it would be possible to run an FFT on the received audio and determine by how much the RX tuning is off, just like with CWT. I am very fond of the CWT feature on the K3 and on the KX3. I wonder if it would be practical to add SSBT as a new feature.
