The K2 and K3 have near perfect equal key ON/OFF delays. Therefore, the
K3 and K2 will not normally need external keyer delay compensation.
The KX3 (measured with MCU 1.50 / DSP 1.21) has about 8 ms key ON to OFF
delay. The delay is for both the internal and external keyers. (Breakin

Hi Fred,
I think this was the thread I previously saw on keying compensation for the
KX3, including scope traces:

Hmmm ... just when I thought I understood everything. :-)
A number of years ago I built a keyer, can't remember if it was the K1EL
chip or not and I don't have it anymore. USB hadn't been invented. It
suffered from what I decided was a design defect in that it offered 2
dah-dit ratios. 3:1

True. As a teen, I was very active in NTS in the mid-50's. Of course,

I considered myself pretty good with a bug back when I started (and
probably had a bit of a 'swing' myself), but today the sound of properly

It is very important to distinguish between Key Weighting and Key
Compensation.
See pages 15 and 16 here: http://k1el.tripod.com/files/WKUSB_QuickStart.pdf
The K3 has Key Weighting. What it (additionally) really needs is Key
Compensation.

Kent - You're right about what the human ear/brain can discern.
Some of you may recall seeing the article about Chuck Adams, K7QO, in the
Wall St. Journal a number of years ago:

With all due respect to Tom (he's been on the air two years longer than I :-)
that's exactly my point - 'weight' and 'ratio' are two different things!!!

Many people confuse "ratio" with "weight". 'Weight' makes both the dots and
dashes longer (or shorter), but preserves the 3:1 ratio between the two.
I've used some radios with internal keyers that have adjustable "weight"
(wrongly named) that only makes the dots longer. Sounds terrible, IMHO.
