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 mode, XMIT not enabled) The KX3 weight control can be used to compensate for the internal keyer delay, though is speed dependent and runs out of compensation above about 25 WPM. At 20 WPM with the KX3 Weight set to 1.15, the resulting transmitter output weighting will be about 1:1. For the KX3 with an external keyer, set the delay to 8 ms.
