Thank you for purchasing the new TS-440S tran- sceiver. Please read this instruction manual carefully before placing your transceiver in service. This unit has been carefully engineered and manufactured to rigid quality standards, and should give you satisfactory and dependable operation for many years.
1 1. Wide dynamic range New advances in circuit design have made a 102 dB dynamic range (500 Hz IF bandwidth) possible. 9. Switchable AGC time constant A switch is provided to select either FAST or SLOW AGC action. 10. All mode squelch 11. Built-in RF power/SWR meter 2.
2. 2-1. PRECAUTION 1. A void direct sunlight, and select a dry, well venti- lated location. 2. Since the heat sink is on the rear panel, avoid plac- ing the equipment with the bottom and rear sides close to a wall or desk. 3. When installing the equipment in an automobile, en- sure adequate ventilation.
2-2-3. Antenna Caution: Protect your equipment-Use a LIGHTNING AR- RESTOR. 2-3-2. Power supply connection Cautions: 1. Turn POWER switch OFF before connecting/dis- connecting the power cable.

@ 1 MHz step switch This switch is used to determine if the UP/DOWN switches will function in 1 MHz steps or only thru the amateur bands. When the 1 MHz step position is selected, the 1 MHz indicator will light. @ TUNING dial (VFO) Rotate the knob to select the desired frequency.
@ Standby switch This switch is used when you want to manually con. trol transmit or receive. SEND: Places the radio into transmit. REC: Places the radio into receive. The Standby switch is also used to clear an entry dur- ing direct entry of VFO frequencies, or when entering a memory channel.

3-2-3. Direct keyboard frequency entry Direct keyboard entry of the frequency is possible us- ing the numeric keypad on the TS-440S. This allows rapid changes in frequency without the delays encoun- tered when using other tuning methods. 1. Select the VFO mode.
3-3-2. CW mode Set MODE keys to CW and set the Meter switch to ALC. ALC PWR SWR c::::m:1:::J (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.
.Subaudible tone An optional subaudible tone unit TU-8 is available for installation in the TS-440S for accessing 10 meter FM repeaters. This tone is activated whenever the TS-440S is in the SPLIT mode. 3-5-1. Why two VFO's Occasionally OX stations will utilize an operational procedure known as split frequency operation.
depressing this switch allows you to receive on the transmit frequency as long as the switch is held depressed. The TUNING dial is active when this switch is depressed, so it is easy to change your transmitter frequency at the same time, if neces- sary.
~ 3-7. SCAN 3-7-1. Memory scan Memory scan operates from memory channel 00 thru memory channel 99 at approximately 3-4 second in- tervals, or you may specify which memory groups you want to scan. Only these memory channels with data entered are scanned.
Note: -~ ,'j The TS-440S microprocessor remembers the variou~ scan parameters that you have specified and will fol- low whatever you have entered the next time you press the SCAN key. In example 1 we want to scan only Group 2, so we would press the 2 key.
3-8. AFSK 3-8-1. Reception Note: An RTTY terminal is required to receive and dis- play/print the RTTY signal. 1. The AFSK mode utilizes the LSB carrier frequency, which conforms to international conventions.
4. This 3rd IF frequency is either amplified and then demodulated by the FM detector IC, for FM operation, or applied to the 455kHz filter. After filtering the sig- nal is amplified and applied either to the SSB or AM detector circuits.
5. formation in the space provided on the back cover of this manual. Service note: Dear OM, if you desire to correspond on a technical or operational problem, please make your note short, complete, and to the point. And PLEASE make it readable. Please list: Model and serial number.
Probable cause 1. Low AC line voltage. 2. RF gain control closed. Symptom The S-meter deflects and stays at a certain position even with no signal. 1. Use a step-up transformer to raise the line voltage. Use a 12 to 16V battery. ~. Turn the RF gain control fully clockwise.
5-8. ADJUSTMENTS 5-8-1. Cover removal Cautions: 1. Before removing the cover, turn the DC power sup- ply's power switch OFF and disconnect the power cable. 2. Do not pinch wiring when opening or closing cases. Removing the covers Remove the top cover (9 screws), filter unit cover (3 screws) and the bottom covers (8 screws) from radio.
5-8-4. Optional 10Hz display resolution If you would like 10Hz resolution instead of the sup- plied 100 Hz display resolution, cut 066 as shown on the Control unit. 5-8-3. Digital display calibration 1. Removing the top cover, filter unit cover and the bottom covers from radio, and place the radio on its side with the antenna tuner area down.
4. Cut the lead of diode 065 located below the dip switch on the control unit. 5. Reverse steps 1.-3. to reassemble the radio. Notes: 1. When reassembling the radio make sure that you do not cut or pinch any wires between the chassis and front panel! 2.
5-8-9. TUNING dial torque Turn the VFO knob while holding the silver ring. As the VFO knob is turned clockwise. drag will be increased. 5-8-10. linear amplifier control As delivered from the factory, the external keying re- lay for control of a linear amplifier is disabled.
6. The following accessories are available for more sophisticated operation of your transceiver. 6-1. CRYSTAL FILTER INSTALLATION 1. Remove the top cover from the radio. Be careful of the speaker lead, which may be unplugged., 2. Remove the seven screws securing the IF unit to the chassis.

10. REFERENCE 10-1-2. Mobile (1) Antenna Use a sturdy mount for the mobile antenna since HF antennas are larger (and have more wind load) and are heavier than VHF antennas.
--J The antenna to be used should first be checked with a dip meter to insure that it is designed for your oper- ating band, then the impedance matching should be checked with an SWR meter. (Fig. 10-3) The VSWR should preferably be less than 1.5: 1 for stisfactory operation.
10-2-2. Noise reduction In motor vehicles, noise is generated by the ignition system. Other sources of noise include the wiper and heater motors. Although the transceiver is equipped with a noise blanker to minimize ignition noise, it is imperative that some preventiye measures be taken to reduce the noise to the lowest possible level.
