[Elecraft] K3 vs. KX3 with wsjt-x

[Bill Frantz]

I indeed had MIC BTN on, and turned it off. I the KX3 still 
didn't go into receive when I pressed the "Halt Tx" button. (MIC 
BIAS was already off.)

Another issue I didn't mention before seems to have gotten 
worse. Sometimes pressing the "XMIT" button on the KX3 doesn't 
take it out of transmit mode. When I press it it stays in 
transmit. Press it again and it still is in transmit. It finally 
goes into receive when wsjt-x gets to its receive phase.

I am still having problems developing a mental model of what is 
actually happening here. Maybe I'll have to download the wsjt-s 
source code and start reading code again. But that's what I 
retired from years ago. :-)
