Hi Don -
I believe you are wrong here in stating that the delay of RF output after
keying is fixed in the K3. Here is an excerpt of the notes from Wayne for
the MCU 1.87, DSP 1.69 firmware update:
...
"* VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu entry, which sets
the time from KEY OUT jack (active low) to first RF in 1-ms steps, from 8
to 20 ms. To minimize loss of QSK speed, use the shortest delay that
works with your amp. Most will work with the default (minimum) setting of 8
ms."

The delay of RF output after keydown is currently fixed in the K3, but
there is consideration being given to allow it to be user controlled in
the future. The adjustment range may be limited, so if you have
transverters and preamplifiers that must have a longer delay to the onset
of RF, the TX INH input would be required.
