[Elecraft] K3 XV50 transverter question

[KD7YZ Bob]

Howdy K3' people:

Is there a setting on the K3 that I could "set" which would cause the
XV50 transverter to receive nicely but not transmit?

I have also a XV432. it functions.

If I take the same driving cables for it and put them on the XV50, then
I can receive nicely ... EME, for example, yesterday. But when I transmit,
or try to, the K3 shows red-LED for xmit; shows 50 to 100mw out, on the
K3 "RF" bars.

However, the same power-supply which shows 5 or 6 amps on xmit for the
XV432, shows no current when trying to make the xv50 transmit .

Also, the inline SSB-Electronics Pre-amp, sequencer, does not remove the
pre-amp when keying the K3, meaning that the Sequencer dos not sense RF
either ... sort of proven by the external power meter too.

I've swapped cables and can receive. In my mind that leaves some setting
in the K3 I have over-looked. Right?
