I'm new to contesting, can someone help me understand the point of a 
10 minute rule?  I don't quite see why it makes a difference if a 
station that has multiple operators, but only one transmitter can only 
switch bands at certain times.

Because of the second rule, it is implied that they are actually using 
two transmitters, but only one can transmit at a time.  But it seems 
like the second rule says the two transmitters each have their own timers.

Ok, I'm just getting more confused.  I am trying to understand how the 
pieces fit together.  My wife and middle son are Techs, and I wanted 
to do a M/S at some point.  Just trying to understand the point of the 
rule.
