Question for Tim and other WSJT-x Users

I'd had my 5K working JT for a while.
And Tim's April 2014  instructions on wsjtx with DAX were great for the 6K.
I have  wsjt-x on both the 5K and 6K.
Both work well, (not at the same time. LOL) (different folders)

But I see a couple of major differences which I assume is related to DAX.

1. 5K, I hear a normal transmit sound and see a reasonable display upon transmit
    6K, I do NOT hear any audio when transmitting and the display on screen is very intense, filling the whole screen modulating in sync with what would be the audio if I could hear it.
I've tried headphone and powered speakers and am obviously missing the setting to apply the what I'm calling "sidetone".
I know I'm getting I'm working stations.

I'm getting my head around DAX, but it's thick (the head) and it's slowly getting through.

Still not clear on the difference between
a DAX RX and a DAX RXIQ  I was able to understand a DAX TX Audio though :-)

If there is a 'article' on this, someone please send me the link.

Hi Bill -- no "sidetone" (monitor audio) with DAX, so you're okay there. Also, the panadapter does go a bit wild on transmit. It may be a bit too sensitive in transmit, and does seem to show "stuff" that isn't "really real." 

DAX RX is an audio-based stream, where the IQ is a much broader sample of the passband, delivered as an I/Q signal instead of audio. I'm hoping we can do JT-modes with it someday. Mostly, I think it's used by the CW Skimmer folks at the moment.

Hope that helps!
