[Elecraft] K3: R/T and T/R timing

[David Windisch]

Hi, all concerned:

The time from key-down to rf-available, is well-defined, and controllable
with the DELAY knob from 8ms to 2s.

Is the time from key-up to no r-f output as well-defined, and controllable?

My concern is hot-switching an amplifier, in my case either a Ten-Tec 425 or
an Alpha 89, operating QSK c-w.

After key-up, on quiet bands or a dummy load, I hear a short "tail" (sounds
like an echo) at the end of each code element.

Is the situation different on SSB?

Any ideas out there, please?

Tia & brgds,
Dave, N3HE
