[Elecraft] K3 bugs

[Don Wilhelm]

Dave,

I am just wondering if Elecraft support actually indicated that this 
condition is a "known bug".

I suspect that with VOX on, the "TX momentarily" would more likely be 
caused by some sort of noise in the shack.
If you have the VOX set sensitive enough, then even tapping on the 
operating desk or moving the microphone (or even chair 'squeaks) can 
cause it to go into transmit easily.
If the ANTIVOX setting is too low, that may trip the K3 into transmit 
with sound from the speaker (or leakage from the headphones.
You may want to check your MENU: VOX GN and MENU:ANTIVOX settings to be 
certain they are not the problem.
Those settings are dependent on the sensitivity of the microphone, 
proximity of the mic to the speakers, and other factors dependent on 
your shack and the ambient noise conditions in the shack, so settings 
that are good for one situation will likely not work well in your 
situation.  The K3 manual text gives some hints for achieving the proper 
settings for your shack.

73,
