[Elecraft] K3 slightly off frequency

[RLVZ at aol.com]

I have a K3 kit that's been back to the factory for repair and alignment,  
and a K3S that was factory made and aligned.  Regardless which  one I'm 
using, most of the time when I get "spotted" by RBN, my  frequency is listed as 
being 100hz higher than listed on the  K3's front panel digital readout.  
This has often made me wonder if  both of my K3's are slightly off frequency.  
Could it be that  many/most K3's are "slightly off frequency"?

A few of  us in Fremont, CA have a weekly 10 meter net. I have a friend 
with a K3 who  always sounds off frequency. When I use my K3, I've been told 
that I am off  frequency. There are a couple of KX3 users who don't seem to 
have a problem.  When I use my Kenwood TS-590 I seem to be on frequency.
Is the K3 known, in  general, for being slightly off frequency??
