I have  it paired up with a Yaesu FT-990 and using the REMOTE jack from the
radio  to key the amp using VOX


I am not surprised, you have the radio immediately making RF and there is a  
slight delay in all the switching due to mechanical relays in the radio and  
amplifier.  I NEVER have seen contesters using vox ever with amps since the  
exchanges are so quick, the relays can't function that fast.  In 45 years  as a 
ham, I never used vox with an amplifier, always used PTT. With PTT (or foot  
switch) you tend to not speak until you press the mic, by that time the relays  
are engaged. with vox, your voice initiates the relays but you have already 
said  a syllable or 2 and they get cut off.  Go with  PTT
