Hi Bob

I also noticed the PTT is not enabled when DVK is used. I have
the voice keyer PTT run the radio but I was hoping to use the
delay feature. This would allow the relays to lock up in the home
brew amps before the  DVK pulse went positive.

I would vote to add it unless I missed something in the setup as well.
