ETTING
During semi-break-in (not QSK) operation, the hang time of the transmitter, after you have finished sending, may be
adjusted to a comfortable value consistent with your sending speed. This is the functional equivalent to the “VOX Delay”
adjustment used on voice modes, and the delay may be varied anywhere between 20 milli-seconds ([
DELAY
] knob set fully
counter-clockwise) and 5 seconds (fully clockwise).
1. Press the [
BK-IN
] button to enable CW transmission
(Menu item “
058 A1A BK-IN 058 A1A BK-IN 058 A1A BK-IN 058 A1A BK-IN 058 A1A BK-IN
” must be set to “
SEni SEni SEni SEni SEni
”).
2. Start sending, and adjust the [ DELAY
] knob so that
the hang time is as you prefer for comfortable opera-
tion.

ERMINOLOGY
:
CW Pitch : If you tuned to an exact “zero beat” on an incoming CW signal, you could not copy it (“Zero beat” implies a
0 Hz tone). Therefore, the receiver is offset several hundreds of Hz (typically), so as to allow your ear to detect the tone.
The BFO offset associated with this tuning (that produces the comfortable audio tone) is called the CW Pitch.
