BTW, all TR-3/4 versions are like this. Earlier T-4 and T-4X are also this way. Conversely, if you leave an open key plugged in, you won¡¯t get TUNE, SSB or AM to work. The rig will key the relay but there¡¯ll be no power out/modulation.?
Later T-4X and all subsequent separate transmitters can leave the key in the jack and still fully work in the other modes without closing the key.?

If the TR-4CW is like the TR-4 (and I believe it is), if the sideband switch is at "X", the mode switch is in "X-CW", and there is no key plugged in (or if there is a key but its contacts are closed), then the rig will be in transmit.

OK. How would it go into transmit without keying the mike?
VOX circuit?
I am not that familiar with Vox?
But I was also trying to set vox and anti-vox according to the instruction manual.
Where should my vox and anti-vox be set so that outside noise won¡¯t trip the transmit?
