TRANSMITTER OPERATION

DIGITAL MODE OPERATION (SSB-BASED AFSK)

monitor ALC voltage. If not, press the [FUNC] key momentarily, then rotate the SE- LECT knob to select to select Multi Function Row “i” [MTR, – – –, DISP], then press the [A](MTR) or [B] key so as to select metering of ALC (“ALC” icon will appear at the upper of the[B]] key).

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

6.Rotate the SELECT knob to recall Menu Mode No-001[EXT MENU], then rotate the DIAL to change the setting to “ON” to enable the extended Menu Mode.

7.Rotate the SELECT knob to select Menu Mode No-037[DIG GAIN].

8.Following the instructions for your TNC’s software, activate the transmitter from the computer keyboard; this should cause the AFSK output from the TNC to be sent to the

radio. While transmitting, view the ALC meter; a few “dots” of ALC indica- tion should be observed. If not, rotate the DIAL knob to adjust the AFSK level within the FT-857for 16 dots of indication on the ALC meter.

9.Press and hold in the [FUNC] key for one second to save the new AFSK level setting and return to normal operation. You are now ready for full RTTY operation.

Because RTTY is a continuous-duty transmission mode, try to keep your trans- missions short when running on battery power, so as to minimize current drain.

PSK31 Operation

Two dedicated PSK31 modes are available, one each for USB-side and LSB-side injection. For BPSK work, the injection does not matter, but for QPSK the two working stations must use the same sideband.

1.Connect the FT-857to your computer’s sound card or interface.

2.Setup for PSK31 operation is basically identical to that previously described for RTTY operation. As before, use the “DIG” mode. However, in Menu Mode No-038[DIG MODE], select “PSK31-L” (for LSB injection) or “PSK31-U” (for USB injection). As with RTTY, Menu #38 may be used to set the drive to the transmitter. And the YF-122C500 Hz filter or YF-122CN300 Hz filter may also be utilized, as described previously.

“USER” Defined Digital Modes

Also provided in the FT-857are two convenient “USER” Digital modes, one each provid- ing USB- and LSB-side injection, which may be used for SSTV, Fax, Pactor, and other digital operating modes.

Here is an example involving the configuration of the USER mode for JT44 (WSJT) opera- tion with USB-side injection (as opposed to LSB injection, used in the default “RTTY” mode):

1. Use Menu Mode No-038[DIG MODE] to set the Digital mode to “USER-U.”

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.
