[Elecraft] [Elecraft_K3] TX CW discrepancy

[Igor Sokolov]

It has started with complains of some of our contacts in the contest. They 
told us that the weighting of out TX CW is not standard.
Two channel oscilloscope was brought into shack and 3 K3 tcvrs were checked:
SN 1651 SW ver 3.06
SN 2929  SW ver 3.68
SN 3553  SW ver. 3.41
On all 3 units series of dots were sent using external keyer with 50% 
weight. While on the monitor output the weight remained to be 50% the RF 
output showed shortening of dots (and therefore lengthening of spaces) by 7 
or 8 msec. This effect does not depend on WPM speed and therefore less 
pronounced at slower speeds.
Could somebody confirm this please. We do not want to trouble Elecraft 
without being 100% sure that the problem exists.
