Kenwood TS-440S manual Wide dynamic range, Build-in XIT, Switchable if bandwidth, 0- 6.19-7/~o

1

1.Wide dynamic range

New advances in circuit design have made a 102 dB dynamic range (500 Hz IF bandwidth) possible.

2.General coverage reception from 100 kHz to 30 MHz

In addition to transmission and reception on all amateur bands from 1.8 to 28 MHz, the TS-440S provides a continuous tuning general coverage receiver with a range of 100 kHz to 30 MHz.

3. Automatic antenna tuner

The optional, built-in automatic antenna tuner will oper- ate from 3.5 to 28 MHz.

4.All-mode operation

USB, LSB, CW, AM, FM, and AFSK modes are

provided.

5.100% continuous duty transmit

Transmission at a 100% duty cycle is possible for rela- tively long durations (one hour or less) in any mode, including FM and AFSK.

6.CW full break-in

Full break-in operation is possible in the CW mode. Rapid transmit/receive switching also makes the radio suitable for data communications in the SSB mode, such as AMTOR.

7. Build-in XIT

XIT (Transmitter incremental tuning) allows fine tun ing of the transmitter frequency.

8. Switchable IF bandwidth

The IF bandswitch allows you to tailor the receiver bandwidth to the operating conditions. Several selec- tions are provided; AUTO, W (Wide), M 1 (Medium 1), M2 (Medium 2) and N (Narrow). When the AUTO po- sition has been selected the radio will select the opti- mum bandwidth for the selected mode of operation.

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

12.Versatile frequency control

.Accurate frequency selection is possible due to the use of a single reference oscillator circuit.

.Continuous tuning of all frequencies thru the use of digital VFO technology. The basic 10Hz step tun- ing rate is modified, according to the selected mode, for optimum tuning speed and accuracy. An auto- matic fast scan function is also provided.

.Dual, digital VFO's (A/B) enable crossband, cross mode operation.

.100-channel memory (including 10 odd-split chan- nels) stores the frequency, band, and mode.

.Memory scan and two programmable scan ranges.

.Direct entry of the desired frequency using the front panel numeric keypad is also possible.

.A memory scroll function allows review of the memory channel contents.

.Selection of the desired memory channel fs possi- ble using either the TUNING dial or microphone UP/DOWN pushbuttons.

.The T -F SET function is useful for split frequency

operation.

.An optional tone unit TU-8 may be used in conjunc- tion with the odd-split memory channels to allow 10 meter repeater operations with CTCSS access.

.Optional computer interface.

.Built-in long-life memory back-up battery.

.2-color fluorescent display tube indicates frequen- cy and other operational data.

13.Front panel control of the TUNING dial torque is provided.
