[Elecraft] CW Transmit Text Decode is off

Well, I think I might know what is going on then.  The timing must be
really tight.  I'm using a single lever paddle, and I think if it polls
when I'm switching from dit to dah, or vice versa, then it breaks the
letter, even if it sounds pretty much OK (well, it's faster than my ears
anyway).

So, I guess the technique is to switch before the last element is sent so
it has enough time to engage the next element before it polls.

I'm actually doing the level 1 CW Academy course.  I guess I have plenty of
practice ahead.  It's pretty embarrassing not being able to send my own
name right :-)

Anyway, good to know I'm not losing my mind (yet).

Thanks,
Cliff
