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 send-
ing speed. This is the functional equivalent to the “VOX
Delay” adjustment used on voice modes; however, this is
an independent adjustment used on CW, so you don’t have
to change the delay when changing from Voice to CW.
The delay may be varied anywhere between 0 seconds
( CW DELAY knob set fully counter-clockwise) to 5 sec-
onds (fully clockwise).
1. Press the BK-IN/SPOT key (# ) momentarily to
enable CW transmission (Menu item “MODE-CW 047
CW BK-IN” must be set to “SEMI”).
2. Start sending, and adjust the CW DELAY knob
(#
) so that the hang time is as you prefer for com-
fortable operation.
Quick Point
The CW Delay feature is the functional equivalent to the
“VOX Delay” adjustment used on voice modes; however,
this is an independent adjustment used on CW, so you don’t
have to change the delay when changing from Voice to

DJUSTMENT
Rotation of the front panel’s CW PITCH control (# )
will allow adjustment of the center frequency of the re-
ceiver passband, as well as the pitch of your offset CW
carrier, to the tone you prefer. The tone may be varied
between 300 Hz and 1050 Hz, in 50 Hz steps.

Terminology
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.
