[TenTec] Using Notch to tune CW with Omni V.

As I understand, Tentec uses 700 Hz as their standard CW offset.  Using the 
600 Hz procedure would this not then introduce a 100 Hz error?

Can't say for the V as I don't have one on the desk.  However, with the Omni 
VI Plus, in the CW mode, I press the CW button and adjust tuning for a match 
between the sidetone and the incoming CW signal.  I can easily get within a 
few Hz using this method.
