Re: [cw_bugs] New to the group
- I measured the spacing on mine and posted the measurement: 2 mm - I
wrote a long email and it was about bugs - how to use, adjust and so
forth. Questions that come up.
I'm sure you can find it by searching the archives of this group.
I measured that a good spacing between the dot contacts (post and
spring contacts) is 2 mm. This was the minimum spacing that I could
achieve without bouncing the dot contacts.
2 millimeters = 0.0787 inches
3/16 inches = 0.1875 inches
3/32 inches = 0.09375 inches
So I was probably talking about 3/32 inch spacing in my comments which
would come out to about the same measurement.
This was the minimum spacing - with slower speeds wider spacing feels
and works better - just like a hand key. Send slow - space wide.

> The trade-off for closer spacing than 3/16 inch is that you risk getting bouncing dot contacts. When the vibrator vibrates, the lever doesn't clear correctly and the dots spark. Split dits - some call it.
