: [Elecraft] Silly question - what is KEY OUT?
It is a T-R relay capable of 200 VDC @ 5 A.

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.

Hi Keith,
From the K3 Owners Manual (Page 17):
KEY OUT (RCA/Phono) is the (linear) amplifier T-R relay keying output,
capable of keying up to +200VDC @ 5A.

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 element is a relay so electrically it's
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
driving this

So I could use it to drive my practice oscillator, ea ? Is it
active when the rig is in TX Test mode

OK, so how closely will it follow the keying if I'm in QSK

I think you and the other responders are missing a key point. As I
understand it, in QSK mode, when you close the K3 Key In, the Key Out
closes and
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

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

The Key
to gate
the KEYOUT-LP on pin 10 and the DIGOUT0 signal on pin 6
Perhaps it should have been labelled LC (low current)?
