FT-891 Advance Manual
CW Delay Time Setting
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 of the “VOX Delay” adjustment used on voice
modes, and the delay may be varied anywhere between 30 msec and 3 seconds via
Menu item “
07-09
[
CW BK-IN DELAY
]”.
1. Press and hold in the [
F
] key for one second
to activate the Menu mode.
2. Rotate the
MULTI
function knob to select
Menu Mode “
07-09
[
CW BK-IN DELAY
]”.
3. Press the
MULTI
function knob, and then
rotate it to adjust the hang time (30 - 3000
msec).
Default:
200 msec
4. When the adjustment is satisfactory, press
the
MULTI
function knob.
5. Press the [
F
] key to save the new setting and
exit the Menu mode to normal operation.
CW Pitch Adjustment
The center frequency of the receiver passband may be adjusted to the preferred CW
tone. The pitch of the CW carrier offset may be varied between 300 Hz and 1050 Hz, in
10 Hz steps.
1. Press the [
F
] key repeatedly to find the “CW
SETTING” list screen.
2. Rotate the
MULTI
function knob to select
“PITCH”.
3. Press the
MULTI
function knob, the PITCH
frequency pop-up screen will appear.
4. Rotate the
MULTI
function knob to adjust
the PITCH (300 - 1050 Hz).
Default:
700 Hz
5. Press the
MULTI
function knob, then press and hold the [
F
] key for one second to exit
the “CW SETTING” list screen and resume normal operation.
r
CW Pitch function may be assigned to the [A], [B] or [C] key. Refer to “Changing the
function assigned to the [A]/[B]/[C] keys” in the FT-891 Operating Manual.
CW Pitch:
If the receiver is 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 hundred Hz (typically), to produce a beat tone that can be heard.
The BFO offset associated with this tuning (that produces the comfortable
audio tone) is called the CW Pitch.
