[Elecraft] CW Rise Time?

[Paul Christensen]

> "My K3 SN 2533 is running FW 3.19.  If the rise is 2.5ms, I sure don't
want to try anything shorter.  I wonder if the change in rise to 2.5ms has 
effected the key line to the
amp?"

I went back to old K3 F/W version 2.19 and the CW rise/fall time on my K3 
lengthened back to 6 ms.  So, my guess is that it changed somewhere around 
the release of version 3 since version 3.14 also shows the faster CW 
rise/fall time of ~ 2.5 ms.

John, I think you'll be fine now when sending K1ESE at any speed as long as 
you're using a newer firmware release.

On the Orion messing with the weighting didn't solve the problem, just
the ris/fall time.  I'll set the K3 weighting to .90 and see if that helps.

I wonder if the change in rise to 2.5ms has effected the key line to the
amp?
