[Elecraft] K3 vs. KX3 with wsjt-x

[Bill Frantz]

I have noticed an significant difference between the way my K3 
and KX3 work with wsjt-x. On the K3, the "Halt Tx" button 
immediately stops transmission on the radio. With the KX3, the 
radio remains in transmit mode, although the computer has 
stopped sending audio. I have to press the "XMIT" button on the 
radio to get it back to receive mode. It is as if the CAT 
command to take the radio out of transmit mode isn't being sent 
or is not being processed by the radio.

Not that on both radios other actions which use the CAT 
interface, like changing bands from the wsjt-x UI, work correctly.

The K3 has been upgraded to the internal sound card/RS232 
interface from the K3S.

The KX3 is being used with a USB <--> RS232 cable and a home 
brew audio interface using a mini-dongle USB sound "card".

The computer in both cases is a MacBook Pro.

Has anyone else experienced this issue?
