[CLAR]

RECEIVER ACCESSORIES

CLARIFIER (RECEIVER INCREMENTAL TUNING)

The Clarifier (RIT) allows you to set an offset of up to ±9.99 kHz of the receive frequency relative to your transmit frequency. To achieve a wider offset than this, you may use the “Split” operating mode, described later.

1.Press the [CLAR] button momentarily to activate the Clarifier function.

2.Turn the SELECT knob, which allows the receiver frequency to be varied over a range of ±9.99 kHz.

3.When the receiving frequency is higher than trans- mit frequency, the “ (within 1 kHz)” or “ (be-

SELECT

yond 1 kHz)” icon will appear to the right of the frequency display. Similarly, when the receiving frequency is lower than transmit frequency, the “ (within 1 kHz)” or “ (beyond 1 kHz)” icon will appear to the right of the frequency display. When the receiving frequency is equal to transmit frequency (Clarifier offset is zero) while the Clarifier is activated, the “” icon will appear to the right of the frequency display.

4. To turn the Clarifier off, again press the [CLAR] button momentarily. When you turn the Clarifier back on, the offset previously stored will still be applied.

5. To reset the Clarifier offset to zero, turn the Clarifier off, then turn the DIAL by any amount. The Clarifier will reset to zero after the first “step” of the DIAL.

[TX<RX (exceed 1 KHz)]

[TX<RX (within 1 KHz)]

[TX=RX (simplex)]

[TX>RX (within 1 KHz)]

1) If you leave the Clarifier on, moving the DIAL will not cause the offset to be cancelled.

2)You may change the knob that controls the Clarifier off- set from the DIAL to the SELECT knob via Menu Mode No-021 [CLAR DIAL SEL].

FT-857 specifications

The Vertex Standard FT-857 is a compact and versatile all-mode transceiver that has become popular among amateur radio operators since its introduction. With its ability to operate in VHF, UHF, and HF bands, the FT-857 caters to a diverse range of communication preferences and provides exceptional performance for both mobile and base station applications.

One of the key features of the FT-857 is its coverage of a broad frequency range, spanning from 160 meters to 2 meters and covering the 70 cm band. This wide frequency coverage allows amateur operators to communicate with fellow enthusiasts across various bands, ensuring versatility in operational environments. The FT-857 offers an output power of up to 100 watts on HF and 50 watts on VHF/UHF, providing sufficient power for effective communication, whether in local or distant contacts.

Another distinctive characteristic of the FT-857 is its all-mode capability. It supports various modes of operation, including SSB, CW, AM, and FM, making it suitable for different operating styles and preferences. The inclusion of advanced digital signal processing (DSP) technology enhances audio clarity and offers noise reduction features, which are crucial in crowded bands. This DSP capability also aids in improving signal quality and overall communication experience.

Portability is a significant advantage of the FT-857. Its compact size and lightweight design make it an excellent choice for field operations and portable setups. Additionally, the transceiver is well-equipped with features such as built-in memory channels, allowing users to save and quickly access frequently used frequencies. The FT-857 also includes a built-in automatic antenna tuner, which makes it easier for operators to set up and optimize their antenna configurations without requiring additional external devices.

The FT-857 is designed with user-friendly controls and a clear LCD display, enabling operators to quickly adjust settings and monitor communication details without confusion. The visibility of the display is especially vital for use in different lighting conditions, ensuring that users can operate efficiently whether in bright sunlight or low light conditions.

In summary, the Vertex Standard FT-857 is a highly capable, compact transceiver that offers an effective solution for amateur radio communication. With its all-band, all-mode capabilities, robust DSP technology, and user-friendly design, the FT-857 remains a popular choice for both enthusiasts and professionals alike, facilitating engaging communication experiences across multiple bands and modes.
