With cw dots you are "pulse" tuning at 30% duty.

Last time I checked, CW dits are one unit length duration, and the
spaces between dits within a character are also one unit length. Most
keyer's these days can have the "weight" adjusted, so that the proportion
is not necessarily exactly what I have said. However the "standard"
timing of a string of dits would result in 50% duty cycle.
## On the yaesu mk-v... u can adjust EITHER the dots or dashes from
1-129 in the menu. Default is dots are 10 and dashes are 30.
IE: dots are X... and dashes are 3X. IF sending a string of dots, duty
cycle is
exactly 50% [measured]. I usually use 10 and 36 for norm
cw use. [ X and 3.6 X]
## however, for pulse tuning an amp... I drop the 10 down to 4-7.... and
the dots are really short duration. I can get the duty cycle as low as I think
8%. Normally, I set if for aprx a 30% duty cycle. 50% is too high, unless
you
are into really heavy RF processing on ssb mode.
## 8% duty cycle, although it works, is too low. ideally, you want to use a
duty
cycle thats the eq of the mode you intend to use [like norm cw or ssb]. If
it's too low, the
B+ will not drop much, resulting in higher pep out readings on a pep meter. [
and also
on an average reading meter].
## 50% works good too. Now, if you really want to load down the HV supply,
you can
increase the duty cycle to well above 50%...like 60-90%.
