Re: [Elecraft] [KX3] New behavior using JT65

[Don Wilhelm]

Brian,

As I told the original poster, I suspect a bad audio cable that is 
picking up noise and continuing to activate the VOX.  He had both VOX 
and PTT active, and I don't know if that has anything to do with it.

I don't think it is a KX3 problem.

What firmware level are you at?

That's weird.  I have not experienced an intermittent VOX.  Mind you, I run
with VOX on all the time and have at least a hundred hours in this mode and
VOX setting.  Very stable.

What firmware level are you at?

Has been happening to me here also. And it is intermittant.

 When I go to transmit, all is well; when the transmission should end,
 the tones stop as expected, but the KX3 stays in transmit (until I hit
 the XMIT button).  Clearly something is amiss.

Re: [Elecraft] [KX3] New behavior using JT65

[Don Wilhelm]

Dave,

You still may want to check that cable - or perhaps the soundcard has a 
high noise floor.

When the audio stops, the KX3 should drop out of transmit when using VOX.
Of course, I don't know what happens if VOX and PTT are asserted together.
Cables are always one of the high failure items in any system.

Try switching to PTT instead of VOX.  I don't know your software
application nor its capabilities, but you likely need a "one transistor
keying interface" to drive the KX3 PTT input.
