Elecraft and ACOM amplifiers have a jack labeled KEY IN, so connecting KEY OUT to KEY IN makes the most sense. Alpha and SPE amps call it a RELAY jack, but most rigs and some QSK amps don't use actual T/R relays any more. A few amps have a jack labeled PTT (RF Kit, Juma). If you connect a PTT jack on a rig to the PTT jack on these amps, obviously that won't work unless both are wired in parallel to a footswitch or PTT circuit to key both simultaneously, but then you can't use VOX.
Yaesu rigs key amps using a jack labeled TX-GND. Icom labels it SEND. Kenwood rigs use a RL pin on a DIN plug labeled REMOTE. KEY OUT makes much more sense than any of these labels IMHO. Any jack on a *rig* labeled PTT is an input, not an output. I can't think of any modern rig that has a jack labeled "PTT OUT". 73, Bob, N6TV On Fri, Feb 11, 2022, 6:49 AM Pete Smith N4ZR <pete.n...@gmail.com> wrote: > Recently, I've been dealing with an issue involving the PTT out > connection on my K-3.

We key our radios for CW - it is not a synonym for PTT.
