I'm no CW op but I'd expect the diode would lengthen the relay release
time, maybe quite a lot.

Hi John,

Some passive parts across the key might have a noticeable effect like
that but the backward diode doesn't have any timing effect. If there is
one it would take lab equipment (atomic clock?) to measure it. At morse
code keying rates any stretching that might be there is 'virually'
nonexistent. And..it *DOES* get rid of that spike induced when the
magnetic field from the relay coil collapses. It's highly recommended in
solid state circuits to preserve keying transistors that are used to
energize relays.
