[Elecraft] [K3] RIT Operation Question

while it works like the manual says, the operation is not 
logical.  Clear should always set RIT/XIT to zero - even 
if it is already zero. I'm a firm believer in the "least 
surprise" philosophy of interface design - operation should 
never be a surprise (even to those who don't read the manual) 
and restoring a previously cleared RIT/XIT offset with a clear 
key is certainly a surprise.
