[Elecraft] my K2 and its different frequencies.

Many thanks to all who answered, including those who helpfully suggested  
that I might be using RIT or XIT without knowing it.  
 
I just put a frequency counter on the BFO on my K2, and it changes about  
70Hz when it goes from receive to transmit.  Yeah, I know, there's not  supposed 
to be any change, but I get a 70Hz CHANGE IN FREQUENCY BETWEEN RECEIVE  AND 
TRANSMIT.  
 
Freq. counter is loosely coupled to the BFO.  
 
Any ideas?
