He's discussing the time from Tx back to Rx -- not a missing transmitted
"dit."
Again Mike, to overcome that problem requires setting Semi-Break-In on the
transceiver to a faster value. However, really fast replies will require
QSK activation of the transceiver and a QSK mod made to the L-4 amp -- or
use of an external QSK device like the Ameritron QSK-5 or the QSK-Master
from Array Solutions.
