All, Is there a command that can be added to the VarAC.ini file to delay data transmission for a few milliseconds after the 'PTT on' CAT command is sent to the rig. Everything is fine on my IC7610 but on the FTDX101MP I think I am seeing unstable data at the start of some transmissions. The TX/RX relay switching seems very slow on the FTDX101MP and because of this I'd like to delay the data acatually being sent for a short time to see if that makes a difference.

You can't change this in VarAC or in the VARA modem. Other than adding an artificial delay on the audio (which would move the beginning cutoff to an end cutoff) I don't see any real solutions to this problem.
I'm afraid it is not possible. VarAC is obeying to the VarAC PTT commands. IT does not decide on when to PTT and when to send out sound.
