it is not an open microphone but a birdie that is microphonic.
all K3's I have seen have some birdies, some are very loud like yours and 
some are so low that they disappear in the noise when an antenna is 
connected. 
Open the top cover and touch or come close to the  board with oscillator and 
you will know where the "microphone" is seated ;-)
