I found it. The 2-pin header is now J10 on the Main Board.
Still no transmit though :(. Wonder if the software thinks there's a
100W PA?

IIRC (don't have the schematic in front of me) it gets the TX/RX state
through the 10-pin IDC connector.

So - now my V12/K9HZ system receives fine. Time to try to transmit.
So
I scrounged up an RG316 cable to connect the TX output of the RF
board
to the LPF control card. Hit the mike button, and ...nothing.
Then I remembered - there's a signal that went from the old V11 LPF
to
the PA, to tell it to transmit.
+12V on transmit. There was a 2-pin header. Does the K9HZ LPF
control
card have such a header? I'm not seeing it on the schematic.
