[Elecraft] K3 Sweepstakes .wav files

[Don Wilhelm]

Bill,

I do not know of a total cure, but one way to minimize the exposure is 
to use PTT rather than VOX which avoids the continuous  "open mic" problem.
Yes, you will have to set the software to activate PTT with either DTR 
or RTS and set the K3 menu accordingly.
The microphone will still be live during the time that PTT is active, 
but that is less severe than using VOX where room sounds will activate 
transmit.

The only other cure is to use a microphone that is muted until its own 
PTT switch is activated (usually mobile microphones).  Most amateur 
microphones are wired "live" to allow the use of VOX, but a few open the 
AF line until the PTT switch on the microphone is activated.  Your exact 
microphone wiring diagram may present clues at how the microphone can be 
configured.  Some microphones do not give you a choice.

73,
