TRANSMITTER OPERATION

FC-30 AUTOMATIC ANTENNA TUNER OPERATION

The optional FC-30Automatic Antenna Tuner provides automatic tuning of a coaxial line so as to present a nominal 50 W impedance to the FT-857’s HF/50 MHz antenna port.

Before operation can begin, you must instruct the FT-857’s microprocessor that the FC-30is being used. This is done using the Menu Mode:

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

2.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.

3.Rotate the SELECT knob to recall Menu Mode No-020[CAT/LIN/TUN]. The default setting for this Menu is “CAT.” Rotate the DIAL to change the setting to “TUNER.”

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

turn the transceiver off.

Operation is similar to the procedure for the ATAS-100/-120:

1.Press the [FUNC] key, as needed, to recall Multi Function Row “k” [TUNE, DOWN, UP].

2.Press the [A](TUNE) key to turn the FC-30on. The “TUNE” will appear on the LCD.

3.Press and hold in the [A](TUNE) key to initiate automatic tuning. The FT-857transmit- ter will be activated, a carrier signal will be sent out, and the coils and capacitors in the FC-30will be selected/adjusted for optimum SWR. When tuning is complete, the trans- mission will cease, and you will be ready for operation on this frequency.

Tuning data will be stored in the FC-30’s Memory system. See the discussion at the nect page for details on how this works.

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.
