Tony,
>...8ms, I think, which is unnecessarily long.
Just yesterday, Rob Sherwood gave a Zoom presentation to the local
SLAARC titled "Transmitter Spectral Purity." He spoke at length about
the evils of fast rise times and cited the optimal rise time as between
6 and 8 ms.
The Elecraft K3 line was described as one of the best behaved CW rigs,
with a rise time of 6ms
Yaesu rigs were denounced for being user-configurable from 1ms to 8ms,
giving owners an opportunity to litter the bands with shorter times and
key clicks.

Subject: [Elecraft] K3 cw rise time
Hello,
This subject came up in a recent conversation, and I had to admit that I do
not know the cw rise time of my K3. It's s/n 444, and does not have the cw
rise time mod that elecraft sells. The firmware is the current version.
I read somewhere that the rise time was decreased in a previous firmware
issue, but I don't know if that's true.
It was originally 8ms, I think, which is unnecessarily long.
Can anyone help?
73,
Tony KM0O
