[TenTec] omni v short dits

Steve -

You asked   "How does the rig know it's "make" is being delayed by a keyer?"

It's the reverse,  the key closure is delayed to increase key-on time, or
decrease
keying-off time,  by the amount of mS you set to match the rig's on delay.
The
adjustment is independent of speed and is used to correct keying distortion
of
various transceivers.

You will note that ARRL tests of key closure versus signal transmit delay of
different rigs are shown.   I measured the mS needed to compensate my
rigs from those test pix.  The Paragon II was "dead on" using the Paragon
(1)
test results.  Saved a lot of fussin".
