Thank you for comments. I amy indeed use ` by chance although I have not done
SO2V by choice.

N1MM claims a bug in K3. 
This is in
http://n1mm.hamdocs.com/tiki-index.php?page=Supported+Radios#K3_and_K3S:

*The K3 contains a firmware bug that was reported several times and never
been fixed which affects users who would like to use PTT via radio command.
If the Esc key is pressed when a CW transmission begins and you are using
PTT via radio command, the radio may not return to RX. The radio RX issue
doesn't occur if the owner disconnects the CW jack from the rear of the K3
radio and doesn't change any N1MM Logger setting. Similar issues have been
reported on other modes. Delay has been added to the N1MM Logger program
when Esc is pressed but the problem still occurs intermittently. The problem
seems to be worse with the very early K3 radios. Until this firmware issue
is corrected, users may notice that the radio does not return to RX
intermittently when using PTT via radio command. When this occurs, make
another transmission and end it with the ESC key.*
