11 OPERATOR CONVENIENCES

Connections

Connect each end of the interconnecting cable to the COM connector or the ACC 1 connector on the transceivers.

DSP-100 Users: You may continue using your DSP-100 DSP Unit with the Transfer function. Connect the interconnecting cable to either the CONT IN or CONT OUT connector on the DSP-100, then connect the unused CONT connector on the DSP-100 to the ACC 1 connector on the transceiver. The transceiver connected to the CONT IN becomes the Master; the transceiver connected to the CONT OUT connector is the Slave.

USING QUICK TRANSFER

Note: While transmitting data, other functions may work more slowly.

Transferring Data

The Master is the transceiver that sends data to the

Slave transceiver. If the Master has the RIT function

switched ON, the RIT offset frequency is added to

the receive frequency to be transferred.

1 Switch ON the Transfer function on each

transceiver.

¥ On the TS-870S, activate Menu No. 54

(TRNSFER) function. For the compatible

transceiver, check your Instruction Manual for

the correct method.

Receiving Data

There are two ways that the Slave can receive the data from the Master:

¥Quick memory 1 (TS-450S/690S: channel 00), or

¥VFO

This choice is made on the Slave transceiver. On the TS-870S, Menu No. 55 (DIRECT) can be set to OFF to receive data into Quick memory, or to ON to receive data in a VFO. Check your Instruction Manual for other transceivers. Set Menu No. 27 (TX INH) to ON for a Slave TS-870S.

When receiving data at the Slave transceiver in the VFO, the data is transferred to the TX side of the VFO that is currently selected. If the transferred frequency is simplex, both the RIT and XIT on the Slave are set to OFF; if a split frequency is transferred then XIT is set to OFF but RIT is not changed on the Slave. The IF filter is determined by the transferred mode. AIP status is determined by the transferred receive frequency according to the AIP band memory.

If the Slave transceiver has a Quick or Conventional memory channel recalled for transmit when the transfer is done, the data will be rejected. To receive data into a VFO, select TX and RX using VFOs.

2On the Master transceiver, press QUICK MEMO [M.IN].

¥If the Master is a TS-450S/690S, press [M.IN], select memory channel 00, then press

[M.IN] again.

¥The displayed receive data is stored in Quick memory channel 1 on the Master transceiver (TS-450S/690S: channel 00) and transferred to the Slave transceiver.

TS-870S specifications

The Kenwood TS-870S is a distinguished transceiver that stands out in the world of amateur radio, particularly for enthusiasts who seek a blend of advanced technology and user-friendly features. Introduced in the early 1990s, this HF transceiver quickly gained a reputation for its exceptional performance, versatility, and reliability, making it a favorite among operators worldwide.

One of the most noteworthy features of the TS-870S is its direct-sampling technology, which allows for superior signal fidelity and processing. This technology enables the transceiver to operate across a range of 160 meters to 10 meters, catering to both casual and serious operators. Its high-performance 16-bit digital signal processing (DSP) facilitates effective noise reduction and filtering capabilities, enhancing the overall clarity during transmission and reception.

In terms of power, the TS-870S boasts an output of 100 watts, providing ample power for various communication needs. The transceiver is equipped with an automatic antenna tuner, which simplifies the task of matching the antenna to the operating frequency, ensuring optimal performance without the hassle of manual adjustments.

Another significant aspect of the Kenwood TS-870S is its user interface, featuring a large, easy-to-read display, and a logically arranged control layout. This makes it accessible for both novice and experienced operators. The built-in memories allow for quick storage and access to favorite frequencies and settings, enhancing operational efficiency.

The Kenwood TS-870S also includes various advanced features such as an optional 2.4 kHz and 6 kHz roofing filter which provides improved performance in crowded band conditions. The receiver's dual VFOs (Variable Frequency Oscillators) enable simultaneous monitoring of two frequencies, which is particularly useful for operators who need to keep track of multiple signals or engage in cross-band communication.

Apart from its technical specifications, the TS-870S is constructed with durability in mind, ensuring that it can withstand the rigors of frequent use. It supports various operating modes, including SSB, CW, AM, and FM, making it a versatile choice for diverse amateur radio activities.
