[Elecraft] K3: R/T and T/R timing - - oops!

Dunno what I was thinking, re DELAY control!  Of course Tom is correct.

Specific to the Alpha (p-i-n diode QSK), the Ip leds overshoot dimly from
normal Ip to as much as 1.5A at key-up in QSK mode.

Adjusting DELAY has no effect on this.

The led overshoot goes away in non-QSK modes if DELAY is set above 0.03.

Grounding the RELAY line on the Alpha without r-f drive causes the same led
overshoot.

As we were.

Brgds,
Dave, N3HE
