FRONT PANEL CONTROL & SWITCHES

FUNC Key

Press this key momentarily to enable the changing of the function of the Multi Function keys ([A], [B], and [C]) by rotating the SELECT knob.

Press and hold in this key for one second to activate the “Menu” mode.

Multi Function Keys

These three keys select many of the most important operating features of the trans- ceiver. When you press the [FUNC] key, then rotate the SELECT knob, the current function of that key will appear above each of the [A], [B], and [C] keys (along the bottom of the LCD). You may scroll the display through 17 rows of functions available for use via the [A], [B], and [C] keys. The available features are shown in page 24.

MODE(t)/MODE(u) Key

Pressing either of these keys momentarily will change the operating mode. The selec- tions available are:

..... LSB ó USB ó CW ó CWR ó AM ó FM ó DIG ó PKT ó LSB .....

DSP Button

Pressing this button momentarily provides instant access to Multi Function Row “p” (MFp), which contains the command key for the optional receiver’s Digital Signal Pro- cessing system. The available functions will appear as the functions displayed above the [A], [B], and [C] keys, as described previously. Pressing this key once more will return operation to the last-used Multi-Function Row (the one in use before the DSP row was engaged).

Press and hold in this switch for one second to activate Menu Item No-048, for adjust- ment of the DSP Microphone Equalizer (see page 51 for details).

POWER Switch

Press and hold in the POWER switch for one second to turn to the transceiver on or off. While the transceiver is turned on, pressing this switch momentarily will engage the “Fast Tuning” mode, to allow more rapid frequency navigation (a small “running man” icon will be observed in the bottom right-hand corner of the LCD).

TX/BUSY Indicator

This indicator glows green when the squelch opens, and turns red during transmit. Dur- ing CW operation, this indicator will glow blue when an incoming signal is tuned to the center of the passband (with IF Shift off). And during FM reception, this indicator will glow blue when a signal is received with a CTCSS/DCS tone matching that to which your transceiver is set.

FT-857 Operating Manual

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.
