This has actually been a topic of several discussions on the KX3 Yahoo
group. If you look at the KX3 on a spectrum analyzer you will see that
when the compressor is turned on that the TX BW goes from about 2.8KHz
to 2.4KHz. I have asked Elecraft if there was a way for another option
to be added if one didn't want that narrow of a bandwidth. I
unfortunately always get comments that the audio is "pinched" when the
compressor is on and many report they hear me better without the
compressor, although the audio is weaker. Opposite of all my other
radios where I always get unsolicited comments on the great audio.
Peter HB9PJT just posted on the KX3 group a great QEX article written by
W9GR about FlexRadio using Controlled Envelope Single Sideband in DSP
producing very effective speech and compression. In reading the article
I kept thinking how much greater the KX3 would be if they could
implement this. Elecraft, is this possible? Please?

Feeling rather chuffed to have my Heil Gold Elite 5.1 mich and my Dr. Dre Beats
ear buds with my KX3. Could run a disco! The Heil has very broad audio response
for amateur radio which I prefer for casual com. I’ve noticed that a ll of that
fidelity goes away when I invoke the audio compressor even at level 1. What’s
actually happening when the compressor is turned on? Is the audio intentionally
shaped differently? Highs and lows clipped off?
