$1NB button

Press to switch the analog Noise Blanker function ON or OFF. This function works best against short duration pulse noise {page 53}.

$2AF gain control

Adjusts the audio frequency gain. Turn the control clockwise to increase the gain; counterclockwise to decrease the gain {page 19}.

$3RF gain control

Adjusts the radio frequency gain. Turn the control clockwise to increase the gain; counterclockwise to decrease the gain {page 19}.

$4RIT/XIT control

After switching ON the RIT or XIT function, turn to select the desired frequency offset with respect to the current frequency {pages 44, 45}.

$5NB control

When using the Noise Blanker function, turn to adjust the noise blanking level {page 53}. To prevent distorting your receive signal, use the minimum blanking level necessary.

$6SQL control

The Squelch control can be used for muting the receiver during no signal periods. The more clockwise that the control is turned, the higher the noise threshold level. Therefore, the stronger the received signal must be to open the squelch. Leave fully counterclockwise for weak signal reception {page 19}.

$7M.CH/VFO.CH control

In VFO mode, turn to step the frequency up or down {page 21}. In memory channel mode, turn to select the desired memory channel {page 55}. The control is also used for selecting boundaries for the Automatic Mode function {page 48} and for selecting Menu numbers when accessing the Menu {page 24}.

qUP/DWN buttons

Use these buttons to step the VFO frequency or memory channels up or down. The selected frequency or channel will change continuously in the direction of the button label if a button is pressed and held down.

wPTT (Push-to-Talk) switch

The transceiver is placed in transmit mode when this non-locking switch is held down. Releasing the switch returns the transceiver to receive mode.

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.
