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 have read that many modern HF rigs will not put out properly

waveform of the keyer output does not look very pretty - or sound
pretty.
How does the keyer in my Flex 5000a compare? It sounds good to me, but
I don't have an oscilloscope to see the output waveform.
Is there a way to key the sidetone without transmitting, thus making
my 5000a the world's most expensive code practice oscillator?
