FT450D in cw mode does not transmit unless PTT is actuated. "BK-IN" not in display despite pressing function followed by vox/store button.

  • $\begingroup$ What do you mean that PTT has to be actuated? Do you need to squeeze the PTT button on the microphone to send Morse code? How are you keying the transmitter, through the key jack on the back panel? $\endgroup$ – rclocher3 Mar 23 at 23:35

According to page 46 of the manual, you must press the F button followed by the STO/VOX button to put the rig in break-in mode, which is indicated by the "BK-IN" icon in the display.
