[Elecraft] KX3 radio settings for WSJT-X

[David Haines]

Here are more details:

All seems to be working fine on 160m-10m except for 17m, so KX3 VFO is 
at 18.100 for the rest of this discussion.

Without WSJT-X running, ATU finds a 1.1 match and TUNE button on KX3 
works as expected.

With WSJT-X running, using the WSJT-X TUNE button causes the following:

1.  KXPA100 power LED's light from left to right _twice_, in 
synchronization with a musical ringing that rises in frequency, then 
settle down quietly to about 100W.

2.  Around the same time Windows reports "USB device not recognized" and 
the mouse cursor disappears.   At this point different things can 
happen:  Maybe the cursor comes back and I can stop the TUNE at WSJT-X.  
Maybe it doesn't and I have to shut off the KX3 with XMIT button.  
Sometimes the PC freezes and needs a hard reset.

3.  The KXPA100 fault table lists no faults.

Anybody seen anything like this?
