[Elecraft] No FT8 Decodes pn 80 Meters

[Bob McGraw K4TAX]

I have and use the same configuration as you describe.   Make sure both 
VFO A and VFO B are in the same mode.   Be sure you are in DATA A 
mode.   With DATA A mode it is a USB mode  as used for FT-8.

The right side of the display on the radio should show SPLIT just above 
the VFO B frequency, then TX with the arrow pointing down to B, and then 
DATA to the right.   When you press and hold DATA MD it should show 
DATA    A  in the VFO B area.

I trust you are running WSJT-X  V2.0 and have the application running as 
stand-a-lone.  Otherwise, no interfaces, no other applications, no 
logging programs or such which could be controlling the radio.
