If you've lost all the electrics then chances are it won't interfere with anything on transmit, and even if you can't receive, at least you can alert the world to the fact that you're up there in the dark and could they please turn on the lights.
Is the Herald report accurate where it implies that the lights were only on because of another aircraft movement? I know that unmanned airfields often have the lights connected to the radio system (not much use in this case, obviously) but this was a manned site.
