>I have mine set
for the max in the menu to 10ms. I usually do not go above 25 wpm for
contesting and dxing. My average ragchew speed is 20 wpm. Has anyone got
expereince with this on their Orion I?
Mark you will have one of the cleanest CW
signals on the bands using your setup. More info:

I disagree regarding the default setting of 5 ms.
Rise/Fall settings in the Rise/Fall Menu are about half
what the display says. Here's some fairly recent data
(November 2005) from NW8L:
#############################################################
Being a "show me" type, I took a digital scope home and looked at the
indicated vs. measured rise times for cw keying in my Orion with firmware
version 1.371.
Scope: Tek TDS210 - 60 MHz, 1 GS/s
2.5 ms per division, time measurement cursors adjustable in 0.1 ms steps
Band was 20 meters, run into dummy load Measured last of a short string of
dits at approx 35 wpm, external keying.
Results in ms, average of 5 measurements:
Indicated Measured
3 2.4
4 3.0
5 3.6
6 4.4
7 5.0
8 5.6
9 6.2
10 6.8

I would never go below 7-8 ms except for extremely
high speeed QRQ. Hopefully Ten-Tec will correct their
Rise/Fall Menu to display the actual values. Then the
default 5 ms setting would be OK, but it is definitely
in "click territory" until they do.
