I have to believe that this one is at least to some extent referring to me as I 
am a huge fan of the x-lock.  Anyone who thinks that their rig is a NBS device 
is dreaming.  OTOH the reality is that the x-lock tends to make the drift w/i 
the TR7 manageable.  

Anyone who understands the technology knows that all x-lock is doing is 
"bouncing" the freq around a small freq "slot" and clocking that against a more 
stable reference.  The rig is more stable than letting the PTO "free run".  
That is only slowing the entire process to a point so that we humans do not 
notice it as much.

No harm, no fowl.  Just comments.
