Ok, using your formula, and allowing for my measurement of dah periods (not just dah sound portion of cycle), substituting equivalent dit sound time (at assumed 3:1 ratio), I get the following conversions:
22 wpm K3 readout measured 0.207 dah period 51.8 msec dit sound equivalent at 3:1 ratio 23.2 wpm calculated by the "1200" formula 21 wpm K3 readout measured 0.219 dah period 54.8 msec dit sound equivalent at 3:1 ratio 21.9 wpm calculated by the "1200" formula 73, Drew AF2Z On Thu, 03 Jul 2008 07:39:55 -0700, andy, ae6y wrote: >Those dashes sound a little long.
