[Elecraft] KX3 Voice Monitor (MON)

The voice monitor in SSB is the processed and filtered I channel of the 
IQ audio stream. Since I and Q baseband signals are combined in the 
transmit mixer and not the DSP, the resulting monitor audio is an 
extremely close but slightly imperfect representation of the transmitted 
signal.

On a practical basis, they should be the same.

Note that the KX3 has a great tool for adjusting Tx EQ and CMP. Record 
your voice using the DVR, then play it back using MON. Adjust Tx EQ and 
CMP and play back the sample and you will be able to hear what your 
signal will sound like to the other station. Doing this "live" with a 
microphone is not nearly as effective due to bone conduction of your 
voice to your ears.

Enjoy!

> Newby KX3 question: how accurate a representation of voice and transmission characteristics does the Voice Monitor provide on SSB (with accurate headphones, not the KX3 speaker)? Is it approximate, or actual?
