Hi Robert,
I am talking about the ¡®tune¡¯ tick box in each FREQUENCY column of the wsjtx bandhopping SCHEDULE, not the Tx ¡®TUNE¡¯ feature on the main page.
It also seems the QDX stops responding to any more commands while ¡®stuck¡¯ in this PTT enabled mode as Wsjt-x comes up with an error message after a while saying it cannot get a response from the qdx.
