But the rules also allow for automatically controlled operation,  
which is exactly what a tracker is. You are trying to apply the wrong  
section of the rules.

Absolutely, as an automatically controlled station. The requirement  
is that operation cease when ordered by the engineer in charge. There  
is no requirement that the cessation occur via amateur radio means.

Nothing grey about this, it is completely illegal. I have never done  
it. Just because you have done it and yet haven't been caught does  
not make it grey. When you push a PTT button, you are controlling a  
transmitter. When you flip power on a tracker though, it is the  
automatic controller that determines the transmit instant, not the  
power switch.

It is not a control link, which has very specific meaning under Part  
97. It is a means to cease operation if you should be notified to do  
so by the EIC.
