WSJT-X v2.1.2. GOT IT!! :-)


Finally!!!  Did the obvious and it worked.... I removed v 2.0.0 and then did a fresh install of v 2.1.2.  Downloaded from the WSJT Home Page and installed flawlessly.  Using Pi4B and Buster. 
WSJT-X is being CAT controlled by Hamlib; RX is SDRPlay RSP2Pro and GQRX.

Tnx to all for the encouragement and ideas.
