dots. (Please use TX TEST mode for this purpose so a signal is not
actually transmitted.) Turning QSK on automatically uses the
equivalent of DLY = 0.00, regardless of the user's DLY setting.
Some operators prefer to leave QSK off to reduce the fatigue of
listening to receive audio between CW elements. To further delay
receive recovery,
use larger values of {XMTR} <DLY>. This
is useful
with slower code speeds.
Also see MENU:TX QSK Method, which provides a way to further
optimize QSK performance.
ANT
Tapping [ANT] cycles through the available transmit antennas, as
indicated by the orange ANT1-2-3 icon in the TX icon area of the
