Do you use split operation on CW?  Curious to know if the DDS osc can handle
the instantaneous shift of frequencies at a fast keying rate.  Obviously there
is a delay compared to the External VFO that runs constantly, but is the
shift noticeable either in a chirp, click or an "enabling delay" that shortens
the dots?
