No CW Transmit - PowerSDR - Flex3000 - HRD 6.4 - DM780

Jim - KC4FWS

Using Flex3000 with PowerSDR 2.8.0.68 by KE9NS with WIndows 10 Pro.  Have Ham Radio Deluxe 6.4, DDUtil, WSJT-X and JTAlert all playing nicely together. 

Now trying to set up DM780 to work within HRD and I have ran into a brick wall trying to get it to send CW from keyboard or using macros.  In DM780 Tools>Program Options>PTT tab I have "via Ham Radio Deluxe..." selected.  With PowerSDR in CWU on 20m I see DM780 sending the code in the receive screen but no output from radio.  I can send with my Bencher key and transmit output is fine.  

I tried selecting USB mode and sending code via keyboard and macro and see code being sent in receive screen and the a couple seconds later the radio gets locked into transmit (MOX) without any power out indicated.  I have to select the MOX button on PowerSDR to unkey the radio. Of course Bencher key does not do anything because the radio is in USB mode.

I have also tried setting a VSP port in DDUtil for PTT, made the Program Options change, went through the same checks as above and that did not work.

Any and all constructive suggestions, welcomed.
