[Elecraft] K3: Question about data modes...

[David Cole]

Hi all,

What EXACTLY is the difference between "AFSK A", and "DATA A".  

Here is why I ask:

In AFSK A Mode:
While using MixW, and looking at the MixW screen, and in USB on the K3,
as I tune using the knob, the MixW screen shows the signal stuck to a
frequency on the top calibration marks on MixW.  The signal never moves
from the frequency indicated on the MixW software in the waterfall.

In DATA A Mode:
All settings the same with the exception of switching from AFSK A to
DATA A.  The signal moves relative to the frequency marks on MixW.  i.e.
if the signal started at 14.0000, as I tune the knob, MixW tracks the
frequency, moving the scale above the waterfall, while the signal
appears to move independently of the waterfall calibration marks...  

I have tried REV sideband on the K3, and the same thing still
happens...  

Is there a resource I can read telling me EXACTLY what each data mode
does?  I have KE7X's book, and that does not explain why I am seeing
what I am seeing...  At least not to me...  I am putting my macros
together, and need to get my head around EXACTLY what the two modes do,
as they set up the radio.
