Dale,
Thanks for the information! I suspected that the shape was already
excellent, being that we are dealing with a software defined radio.
This helps a lot to answer the question definitively. And no, as a
newbie I had not paid attention to the form well enough to see the
change in the rise and fall times.
To all you CW ops: See the two definitive replies I go below.
Flex is a great radio company. The maintenance of this server, and
others as well, show it. The attention to detail in the software is amazing.
The fact that we have this server for the questions asked and the
answers given is unheard of from any other radio manufacturer. The
entire Flex Radio
company and on-line gang is amazing. Why any one would want any other
radio is beyond me.

Hello Brad,
I've monitored the rf envelope of the FLEX-5000 with an oscilloscope,
and in my opinion, the keying envelope shape is textbook perfect. The
FlexRadio has got to be the most polite radio being manufactured today,
when it comes to clean keying. You probably are aware that you can
change the rise/fall times, though the default 5mS seems exactly right
to me.
As for the timing of the elements, they are very accurate, and if you
use Mode B, you'll also have the ability, via the Setup> DSP> Keyer
panel, to select "Mode B Strict" and "Strict Char Space" which helps the
sender to maintain proper spacing between characters.
I agree that the internal keyers of some current production
transceivers, including several that have a very good reputation for cw,
are lacking when it comes to properly spaced characters, and proper
weighting. The FLEX-5000 is definitely not in that camp!

I use the "panascope" setting most of the time. When keying CW, I can see
the characters. This gives me a pretty good idea of what I am keying and a
visual indication of what the weight is. For me, it's as useful as using an
oscilloscope.
