As I recall, based on owning the TS680S some years back, the 140 does
indeed have VOX. The 680 did not since it replaced the switch to use
VOX mode with the preamp switch.
I think that the VOX mode switch is one of the small controls at the
lower left of the front panel. The standard VOX controls (not jack) for
gain, anti-VOX and delay should be on the back panel.

There's a vox jack on the back of the TS-140.
Is there a vox circuit in that tcvr? If so, what do I have to do to get it
working?
If not so, what can I do to get one rigged up?
I want to do hands free ssb.
Thanks
