"Most folks assume there will be no delay between KEY closure and KEY OUT closure, but there is an extra delay (of about 5 ms, minimum) in the K3S."

I suppose I'm not in the "most folks" group.  I measured this delay when investigating the keying characterisitcs of my  Kenwood TS-590S.  Key down to amplifier relay closure was 2 ms for the configuration under test.  RF started rising about 14 ms after key closure.
