activating antenna relay with XTL5000 consolette

[adlertom]

I'm looking to activate an external antenna relay whenever an XTL5000 consolette is transmitting. I've perused the pinouts of rear connector 2 and connector 3 and don't see anything obvious that I can use. Can anyone advise if there's a way to do this? Thanks.

These are the pinouts for connector 2 and 3. Can anyone advise something that would work for activating an antenna relay? I assume pin 10 on connector 2 is for keying the consolette, and would not change state in response to being keyed?

The consolette has the TRC option, and I'm already using a tone remote on connector 2, if that matters.
