3: SCROLL TO PC KEYING AND SET TO "DTR". (the default for this is OFF)
As soon as I changed that to "DTR" the transmit started working. There is one other thing that I found and is under OPERATION SETTINGS - TX GENERAL - VOX SELECT IS CHANGED TO USB. But I wouldn't change that unless setting PC KEYING TO DTR doesn't all by itself fix your problem.
I had a tough time until I found the "DTR" setting. Let me know if this fixes your problem.
It would really help us help you if you can send a screenshot of your VARA HF Soundcard settings, as well as the 710's menu settings Mode/PSK Data > MOD Source.
Gene, on my FT-710 I had to set:
1: CW SETTINGS
2: MODE CW

PSK settings are all default values except for Narrow Width which is 2400.
I am assuming you are in USB-D as that is a given
