Dave, the rise time alone is not all that is involved. Of almost equal
importance is the nature of the r-f envelope transitions from off to on and
back to off again. If they are rounded and "smooth" (low higher derivatives)
there will be fewer transients and artifacts than if they are sharp and
abrupt.

Looking at the K2 keying envelope at the ARRL review, I see about a 5 ms
rise time. This shouldn't produce excessive key clicks. What's up? And, I
ordered a K2 kit this week (not yet shipped- hurry!)- will it have the key
click mod included?

Hi Dave,

We'll make an announcement when it's ready to ship. We've been doing a lot
of
testing, which so far is going extremely well. One tester who made careful
measurements (Earl, K6SE) reported that the observed click bandwidth had
dropped
from +/- 1500 Hz to +/- 200 Hz, making the K2 as good or better than any rig
he
had previously tested.

The mods are easy to make and will be fully documented.
