[Elecraft] k3S usb software silenced sidetone and no rf out

You said:

No, it cannot.

You need to set the N1MM+ configuration for the radio control port and the
CONFIG:PTT-KEY menu item in the radio to match one another.

For example, if CONFIG:PTT-KEY is set to OFF-RTS, then in N1MM+ you must
configure DTR to Always Off and RTS to CW.

Or, if you have configured DTR to CW and RTS to Always Off in N1MM+, then
you must set CONFIG:PTT-KEY to OFF-DTR.
