Can there be a delay before xmit after pressing the XMIT button on my K3?

[Bob KD7YZ]

Howdy K3' people:

I use a sequencer which helps ensure that RF does not flow from the K3
before a sensitive LNA is switched out of the RF path.

This works if a foot-switch is pressed here. It  works when the
Tigertronics "SignaLink USB" closes the sequencer's PTT  input.

However, the K3's "XMIT" button will key the rig and I see no wy to have
that action tell the Sequencer that it's internal PTT needs activation.
This would need doing prior do RF flowing.

If there was a way that a delay could be chosen/set to follow the
pressing of XMIT button then I might try using the K3 PTT out or the
XV144 Key-Out.

I would like to think I will not press the K3 XMIT button but that "ain't
gonna happen" as I am likely to use "XMIT" with a reduced output to tune
an external 2m PA .

Or, sometimes I am just stupid and press XMIT anyway ... wouldn't be
nice to destroy an expensive LNA ..... especially in the middle of a
QSO with a severely weak station.

In the K3s menu there is a TX Delay setting. Maybe that will accomplish what you need.

On Thursday John_N1JM used a Straight-Key to send:

In any event, irrespective of the delay( and I set it to 30ms anyway),
the K3 sends no signal to the sequencer when the K3 is activated
by either the CW key/paddle being tapped, nor by the XMIT/Tune (and or)
being pressed.

Or at least this is what I am seeing as I try to stop myself from doing
as I did moments ago and swipping at the Vibroplex key-paddle, which in
turn activated the K3 which was in CW mode.

Fortunate for me I had the RF lone form the rig unscrewed form the line
which goes to the LNA.
