[Elecraft] WSJTX ON A MAC

[Richard Ferch]

ERR PTT often means that CONFIG:PTT-KEY in the K3 is set to RTS-something
(or DTR-something), and something in the computer is activating RTS (or
DTR) at the time the radio is powered up.

If this is the cause, a simple solution for this is to set CONFIG:PTT-KEY
to OFF-OFF (or OFF-DTR if you want to use DTR for CW keying), and in your
radio control software (WSJT-X and any other programs you use for radio
control) use CAT for PTT control.
