CW Transmit Request Delay

Is there a programmable delay for the beginning of RF output after the Transmit Request line is pulled down? This delay is designed to let the antenna switching relay settle before the start of the RF signal out in an amplifier. My amp uses a fast vacuum relay but probably needs a few Msec delay to be sure it's fully settled.

    In Smart SDR, go to Settings (upper left corner), Radio Setup,  then under the Transmit tab you will find TX Delay.  This is where you enter the delay (ms.) needed before RF appears after the PTT line is enabled.  I have an ACOM amp and use 10 ms. delay.
