OPERATION

ADJUSTING THE AUDIO VOLUME LEVEL

Rotate the AF knob to set a comfortable listening level.

AF

When operating in the “DIG” or “PKT” modes, you may set the AF knob to any comfortable setting, or even all the way off, because the output from the DATA jack is a fixed-level audio signal.

Start with the AF knob set fully counter-clockwise, especially when using FM (the background noise on FM can be surprisingly loud)!

MENU QUICK START

Many aspects of this transceiver’s configuration may be customized using the convenient “Menu” system, which allow you to configure many “set and forget” settings just the way you want to. A full discussion of the Menu system begins on page 94; for now, here is a brief discussion on how to change Menu settings:

1.

Press and hold in the [FUNC] key for one second

SELECT

 

 

to enter the Menu mode.

 

 

2.

Rotate the SELECT knob to recall the Menu Item

 

 

 

to be changed (for example, Menu Mode No-005

 

 

 

[AM MIC GAIN], which allows setting of the Mic

 

 

 

Gain for the AM mode).

[FUNC]

DIAL

3.

Rotate the DIAL knob to set this feature (in this

example, the default setting is “50,” so rotate the DIAL knob if you want to raise or lower the Mic Gain level.

4.Press and hold in the [FUNC] key for one second to save the new setting and exit to normal operation.

If you had previously pressed the [FUNC] key to enable the changing of the func- tion of the Multi Function keys ( [A], [B], and [C] ) by the SELECT knob, you’ll

need to press it again after exiting the Menu mode.

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.
