I, too, have never understood the "mega-dit" adjustment philosophy.
How many dits the key produces depends upon the amount of throw too. I have mine set for 50/50 weight and then set the throw for perhaps 8 or 10 dits before the weighing climbs. Brian Murphy, VE2AGO, wrote an excellent piece about bug adjustment that agrees with our choice to adjust the bug for only the dits needed. Vibroplex has posted it on their web site at: http://www.vibroplex.com/original_bug_adjustments.pdf Another point Brian makes is that if the damper isn't adjusted properly, the pendulum will slam into it and still be wiggling when the next dots are sent. That results in "scratchy" dits since the pendulum is experiencing a complex vibration mode. IMX, that's not the only reason for scratchy dits but it is one reason. Ron AC7AC -----Original Message----- I hear no problem with my bug on the K3 (VizBug right-angle model, about 30 wpm). Even when I let the dits run out they transition smoothly into full contact closure. I do have the dits adjusted a little on the heavy side, about 60/40 initially as shown by the sidetone waveform (i.e., contact is about 60% of cycle). They fill out to about 80/20 on the 13th dit, then full contact closure. That is according to a waveform made on my K2; haven't made one on my K3. But it sounds ok to me. I think it is standard practice to adjust a bug to get 20 or more dits out of one swipe, but I don't see the point of it since you never need to send more than 5 dits in a row. I would rather have them heavier-- put more energy into them. Maybe this has something to do with the K3 bug problem? 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
