Which does horrible things if you run the sound card level too high in
the PC or forget to turn off the compressor in the rig.  The big benefit
of PKT in the Yaesu rigs is that it makes sure the compressor is off and
the mic preamp is bypassed so you do not cause clipping *before* the
mic gain control.   It also avoids external switching that can fail and
introduce hum/distortion.
