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.
