Still, the adjustment is a bit tricky.
A higher threshhold also has loss of softer speech as a side effect.
When room-noise and speech approach the same level the gate has a rough
time, a common situation in contests/fielddays with people and fan-cooled
equipment packed closely together :-)

Somehow I still feel a small modification to the open/close slopes could
help the gate.
A slightly less steep slope at the opening of the gate might prevent
over-sensitivity to small spikes or "self"-modulation by room noise/ LF
noises.
A gentler slope at closing of the gate will prevent the switching effect you
hear. A smooth slope (soft tail-out) would be much less noticable.

As it is programmed now I can imagine people think they hear cross-over
distortion, a bit similar to SSB with class C amplification.

Thus, the Noise Gate is not a clipper or "waveform modifier" and 
introduces no crossover or other distortion when it is activated.  In 
this case, the speech overrides the noise source during speech, and the 
timer silences the audio path when there is no speech.  However, if the 
threshold is too high, then "leading edge" distortion may result.
