[Elecraft] [K3] weird VOX experience with headset mic

[David Gilbert]

If I understand you correctly, I experienced a similar situation with a 
very nice Razer gaming headset (for video games, etc).  It has great 
over-the-ear cloth padded cups, an electret microphone element, and is 
built very solidly.  In VOX mode on SSB it kept triggering into transmit 
unless I turned the headphone volume way down.  As best I can tell, the 
boom for the microphone is so solid that sound vibrations from the cup 
are traveling down to the microphone element.  Thus far I haven't been 
able to make it go away with ANTIVOX.  I have a half dozen other 
headsets and none of them exhibit that problem, but none are built as 
mechanically solid as that one either.

They don't carry the Yamaha CM-500)  It works beautifully with one funny problem - if I try to use VOX, the radio goes into transmit mode even if I have the microphone muted.  I figure the receive audio must be inducing enough signal on the mic leads to trip the VOX.  No setting of ANTIVOX gets rid of this.  I have the audio from the K3 as low as possible.  Any experiences and suggestions welcome!
