Completely correct, Ron.  I'm possibly beginning to sound like a broken 
record, but I can't see why anyone would want to do this.  The power 
saving only applies when the key is actually down, which is a VERY small 
portion of your total operating time.  In my opinion, that doesn't 
justify the limitations it imposes.

If you are serious enough about backpacking to think that you might want 
to do this mod then you should get a K1!  Not only does it have much 
lower current drain on both receive and transmit, but is much smaller 
and lighter.
