[Elecraft] KRC2 relay control

[Rich]

I have research this idea on my own and do not see a way to do what I 
want.  I know there are really smart folks on this list so I am looking 
for some help.

I was hoping to control the 12vdc (ON/OFF) for my RX ant preamp via the 
K3 keyboard commands (Writelog, N1MM).  I was thinking this could 
possibly be done via the sink/source relays in the KRC2.   I already use 
the KRC2 for band decoding,  but it appears to me that the relays only 
react to band changes.  Are there  computer controllable commands for 
the A B C D relays in the KRC2 or any other ideas?

I hope this is clearer than mud.
