[Elecraft] K4 feature suggestion

[Martin Sole]

A cough switch sounds like a great idea, but a bit low tech. K3 users 
are mostly familiar with the Tx Gate function that blocks audio below a 
threshold level to reduce background noise. Would it not be possible to 
recognise audio input above a certain pre-settable level and have that 
also block transmission. Normally a cough or sneeze is much louder than 
our normal speech (ignore this if you purchase larynx oil and practice 
for the appearance of P5 on a regular basis!).
