With all due respect to Fred, I think that's because the K3 (and probably
the KX3) weight adjustment seems not to change the weight at all, just the
ratio.

'Weight' will add a bit of time to each dot/dash character equally, and
preserve the 1:3 and 1:1 ratios. (Am I opening a can of worms here?)

I use a version of the Super CMOS keyer, and like to add a bit of weight.
I can also do it within the control software for my microHam keyers.

Another reason to use an external keyer, IMHO.

Hi Ralph,
You know, I've always thought that weighting referred to the Dah:dit
ratio, and some references out there in googleland say that. Others
(K1EL winkey documentation has a good explanation) support that it is
the Dit:space ratio that changes. In any event, the K3 and the KX3 are
different and they don't preserve the 3:1 Dah:dit that I like to hear.

Cheers and 73,
Fred

'Weight' is dot to space ratio. The duration of the dots is derived from the speed and the dot-space ratio, and the dash duration is then derived from the dot duration and the dot-dash ratio.

Although there seems to be disagreement about the most pleasing weight, most CW operators prefer a precise 1-3 dot-dash ratio.

I've tried using an external Logikey K-3 w/ my K3 (one would think that
would be a perfect match ;-) ), but when QRQ is turned off, the K3 can't
follow the external keyer past about 38 WPM. That's a problem because
QRQ is disabled when operating split, and that's frequently when higher
cw speed is needed in chasing DX in a pileup situation.

The internal keyer works much better in this regard though the weight
setting with the internal keyer has to be changed depending upon QRQ or
not QRQ, and if QRQ is off, the weight has to be adjusted to a higher
number with higher cw speeds compared to the setting required for speeds
around 25 wpm.

I would very much like to take advantage of the auto-spacing
functionality of the Logikey K-3, but when QRQ is turned off or
disabled, the K3 keying weight lightens up too much as the speed is
increased -- and falls apart completely at about 38 wpm. (at least mine
does...)

I would guess that the K3's microprocessor has greater control over the
keying when using the internal keyer as opposed to an external keyer.
