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 mode 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.

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.

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.

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.

3.

The PWR meter reading may not be accurate with

high SWR values. Use a good antenna for the most
accurate readings.
