(B) Full-Automatic Break-In - Kenwood TS-440S Instruction Manual

3-3-2, CW mode
Set MODE keys to CW and set the Meter switch to
ALC.
ALC_ PWR _SWR
_
Placing the Standby switch to send and depressing the
CW key will cause the radio to transmit.
Transmission is also possible when in the SEMI or FULL
break-in rode by simply depressing the key, with the
Standby switch in the REC position.
Adjust the CAR control until the meter deflection is
within the ALC zone.

¢ SEMI and FULL break-in
Two break-in methods are provided with the TS-440S
transceiver, SEMI and FULL break-in. With either break-
in operation depressing the CW key will cause the ra-
dio to transmit without the need for manually switch-
ing the SEND/REC switch. The difference between
FULL and. SEMI break-in is that during FULL break-in
operation it is possible to listen between dots and dash-
es, and that during SEMI! break-in it is not.
Note:
With either SEMI or FULL break-in operation, cross
band/cross mode operation is not possible. Addition-
ally, when you are using FULL break-in operation you
should not work cross band splits, only in the same
band.
The TS-440S also provides a side-tone oscillator cir-
cuit to allow monitoring of your CW signal during trans-
mission.
{a} Semi-automatic break-in
Depressing the CW key will automatically place the
transceiver into the transmit mode. Transmit mode
will be maintained for a period determined by the
setting of the VOX DELAY control on the rear panel
of the transceiver, even after the CW key is
released.

VOX OFF ON
(b) Full-automatic break-in
Depressing the CW key will automatically place the
transceiver into the transmit mode. Releasing the
CW key will return the radio to receive immediately
enabling reception between characters.
Caution:
The TL-922A/922 linear amplifer is not designed
for full break-in type operation. Attempting to use
this accessory in the FULL break-in mode cause
damage to occur to the linear amplifier.
CW OFF _ SEMI FULL
On occasion an electronic keyer may be used that
has no method of producing a continuous trans-
mit condition. In order to obtain a continuous car-
rier for tuning simply place the Standby switch to
the SEND position.
3-3-3. FM mode
Select the desired frequency within the 28 MHz
amateur radio band. Place the MODE key to FM and
the Meter switch toe ALC.
ALC_ PWR SWR
—_—
Press the microphone PTT switch or place the Stand-
by switch to SEND.
Adjust the CAR control until the meter deflection is
within the ALC zone. This will provide full power in the
FM mode. -
To decrease the power, place the Meter switch to PWR
and while observing the meter rotate the CAR control
counterclockwise until the desired output level is ob-
tained.

Notes:
1. The FM power output may fluctuate if running less
than full output.
2. Ensure that an antenna with a low SWR is used.
The TS-440S provides several protection circuits,
continually loading into an antenna with a high SWR
(3 to 1 or greater) will eventually cause damage to
the final amplifiers.
. The PWR meter reading may not be accurate with
high SWR values. Use a good antenna for the most
accurate readings.
