4-4-1. CW zero-beat Operation
In CW operation equalizing the receiving frequency
with that of your transmit is called "Zero beating".
The TS-850 enable you to zero beat in the following
manner.
A.
Press the TUNE key and adjust the tuning knob so
that the signal from the other transceiver is zero
beat, and deactivate the TUNE key. The CW can
then be used with the other transceiver zeroed in.
B.
1. If the VOX/MAN switch is VOX, set it to MAN and
depress the key.
2. A side tone will be heard from the speaker.
3. Adjust the TUNING knob so that the transmit
frequency of the station you are receiving is equal
to the side tone frequency.
Zero beating is now completed.
4-4-2. PITCH function
You can specify the desired pitch of the receive tone
during CW reception.
1. Press the PITCH key during CW receiving.
2. Select the desired pitch with the M.CH/VFO CH
control.
400++450++500++550-+600++650++700

State) (He)
3. When the PITCH key is pressed again, the pitch
is set, and the normal frequency display returns.
4. The sidetone frequency is the same as the
frequency set for the pitch.
4-4-3. Electronic Keyer Circuit Operation
Place the ELECTRONIC KEY switch on the rear
panel to ON. Connect a paddle type key to the CW
KEY jack use a 6.0 mm diameter stereo plug.
Adjust the KEY SPEED control for the desired
speed.
Weight Adjustment
The ratio of dot / space / dash can be adjusted as
follows:
DOT SPACE DASH SPACE
1 Lea : 3 } 1
The dot-dash ratio has been factory preset to 1:3
and will remain so regardless of the keyer speed.
You can forceable change the ratio to you own
personal preference or you can select AUTO-
WEIGHT control where the weighting adjusts for
changes in keyer speed.
@ Auto Weight (Initial state) [When the Power on
function selection (Number 21) is ON.]
The dot-dash ratio can be set according to the
keying speed. The reverse mode can be turned on
or off with the power on function (menu number 22).
(Please refer to Section 4-10-15.)

Notes
1. It requires a little time to change the ratio at
about the 3 and 7 positions of the KEY SPEED
control where some hysteresis occurs.
2. These dot/dash ratios are only approximate.
@ Manual Weight [When the Power on function
selection (Number 21) is OFF.]
The dot-dash ratio can be set between 1:2.5 and
1:4.0 with the power on function (menu number 23).
(Please refer to Section 4-10-15.)
For the CW message storing, see Section 4-13.

WESEMI and FULL break-in operation
Two break-in methods are provided with the
transceiver, SEMI and FULL break-in. With either
break-in operation, depressing the CW key will
cause the radio to transmit without the need for
manually switching the REC / SEND switch. The
difference between FULL and SEMI break-in is that
during FULL break-in operation it is possible to listen
between dots and dashes, and that during SEMI
break-in it is not.
