First thank you for the QSO.  You are one of the few Europeans I have worked on 
160 with my very modest station in southern Arizona and are a new one for me.

I think the that the key here is "a few Hz" offset.  Of course 100 Hz is more 
than a few and would be too much for a receiving station with a 50 Hz filter in 
use.  I will just turn on XIT and dial in +/- 20 - 30 Hz.

As a practical matter in my case, I will in all likelihood not be heard in any 
pileup of central or east coast USA stations anyway.
