[arm-allstar] PTT Delay idea

[john at qso.com]

I was wondering if there's a way to delay PTT for 200 milliseconds (but not
the audio stream) so that my ALC can properly level out before anything is
heard on the repeater?  The people on the repeater network I'm on are pretty
good about holding the key down for a second or 2 before talking, so it
would be a big deal.

Another option I was thinking about would to have a tone or white noise or
anything really.. keep the ALC circuit busy and leveled during times of
non-transmit.  Anyone have an idea?  I already have a burst of noise at the
very beginning of the repeater ID, I would just want that to be during the
200ms.
