Perhaps it should have been labelled "LC" (low current)?

This isn't a bug, it's the way it was implemented. Originally, whenever in cw,
hitting the key would cause the rig to transmit, either in VOX or PTT mode. A
change was made so that the rig would not transmit unless it was in VOX or the
PTT was engaged. In PTT mode, the rig still keys but doesn't

Elecraft] Silly question - what is KEY OUT?
Hi Keith:
The Key Out relay is only energized during transmission. This is what
you would want for an amplifier. So for example if you turn your VOX off
and press your key or paddle, the Key Out relay will not energize. If
you turn your VOX on it will energi
Hi Keith:
The Key Out relay is only energized during transmission. This is what you
would want for an amplifier. So for example if you turn your VOX off and
press your key or paddle, the Key Out relay will not energize. If you turn
your VOX on it will energize but you will also be transmitting.

I think you and the other responders are missing a key point. As I

Yes - and it is an output because it is the K3 that making a condition
available (switch closure) to the outside world. An input is something
coming from the outside world that would control the K3. The K3 'sends'
either an open circuit or a conducting condition - it is a HEXFET

Subject: RE: [Elecraft] Silly question - what is KEY OUT?
Think of it this way. Just as in software, "Out" refers to the flow of
data or control. The terminology doesn't require a source of voltage
... only a "direction of command".
In this case, the control
Yea, I knww, but I'm a SW person so I sometimes get lost in the EE
details, even when they are very basic.
By "T-R Relay keying output" I guess it means it is a relay that can be
used to control the T/R switching of an external amp. In other words,
the KEY OUT jack acts like a switch, open /

What is this output? Is it a source or sync? It it a switched 5V logic
level or is it a relay closure line that switches from open to short?

Kieth,
From page 17 of the manual
"KEY OUT (RCA/Phono) is the amplifier T-R relay
keying output, capable of keying up to +200VDC
@ 5A."
KEYOUT-LP at pin 10 of the ACC connector is similar, but the max voltage
is lower and it is limited to 10 ma.
