TRANSMITTER OPERATION

CW TRANSMISSION

Operation using Straight Key/External Keying Device

When using a straight key, an external electronic keyer, or a computer-generated keying device, please follow the instructions in this section.

1.

Insert your key’s plug into the rear-panel KEY jack.

 

KEY GND

2.

Press the [MODE(t)] or [MODE(u)] key, as needed, to select

KEY

 

 

one of the CW modes (CW/CWR).

GND

 

 

The “CW” mode utilizes USB-side carrier injection, while the

CWR (Reverse) mode utilizes LSB-side injection.

3.Press the [FUNC] key momentarily, then rotate the SELECT knob to select Multi-Function Row “j” [SPOT, BK, KYR]; press the [B](BK) key to engage the “break-in” system; the “u” icon will appear at the left side of the “BK” notation.

4.When you close the key (or activate your computer-generated keying interface by what- ever means), the transmitter will automatically be engaged. When you have finished sending, the receiver will return, after a brief delay (see next section).

5.The CW “hang time” (the delay after the last character is sent, until the transceiver switches to the receive mode) can be adjusted using the Menu Mode. To adjust the CW hang time:

ŸPress and hold in the [FUNC] key for one second to enter the Menu mode.

ŸRotate the SELECT knob to Menu Mode No-024[CW DELAY].

ŸRotate the DIAL to select a longer or shorter delay time (default: 250 ms). If the delay selection is set to “FULL,” the transceiver will operate in the full break-in mode (allowing you to hear between the characters that are being sent).

ŸWhen you have set the desired delay, press and hold in the [FUNC] key for one second to save the new setting and exit to normal operation.

6.To practice your CW sending (without transmitting), press the [B](BK) key to make the “u” icon disappear. Now, pressing the key will cause the CW sidetone to be heard, but your radio will not be transmitting a signal on the air.

7.You can adjust the CW sidetone volume level via Menu Mode No-029[CW SIDE TONE]. To adjust the CW sidetone volume level:

ŸWhile still in Multi Function Row “j” [SPOT, BK, KYR], press and hold in the [B](BK) key for one second. This is a “hot key” feature which will instantly recall Menu Mode No-029[CW SIDE TONE].

ŸRotate the DIAL to select a new level; on the arbitrary scale of “0” ~ “100,” the default value is “50.”

ŸWhen done, press and hold in the [FUNC] key for one second to save the new setting and exit to normal operation.

8.You also can adjust the CW sidetone pitch using Menu Mode No-027[CW PITCH].

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.
