MISCELLANEOUS SETTINGS

OPERATION ON ALASKA EMERGENCY FREQUENCY:

5167.5 KHZ (U.S. VERSION ONLY) SECTION

97.401(d) of the regulations governing amateur radio in the United States permit emergency amateur communications on the spot frequency of 5167.5 kHz by stations in (or within 92.6 km of) the state of Alaska. This frequency is only to be used when the immediate safety of human life and/or property are threatened, and is never to be used for routine communica- tions.

The FT-857includes the capability for transmission and reception on 5167.5 kHz under such emergency conditions via the Menu system. To activate this feature:

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 select Menu Mode No-050[EMERGENCY].

4.Rtate the DIAL knob to select “ON.”

5.Pess and hold in the [FUNC] key to exit the Menu mode.

Emergency communication on this spot frequency is now possible:

6.Press the [V/M] keys, as necessary, to enter the Memory mode, then rotate the SELECT knob to select the emergency channel “M-EMG,” which is

found between channels “M-P5U” and “M-001.” Note that the receive-mode CLARIFIER functions nor- mally while using this frequency, but variation of the transmit frequency is not possible. Activation of Menu Mode No-050[EMERGENCY] does not enable any other out-of- amateur-band capability on the transceiver. The full specifications of the FT-857are not necessarily guaranteed on this frequency, but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency communication.

7.If you wish to disable operation on the Alaska Emergency Frequency, repeat the proce- dure detailed above, but set Menu Mode No-050[EMERGENCY] to “OFF” in step 3 of the procedure.

In an emergency, note that a half-wave dipole cut for this frequency should be approxi- mately 45’3” on each leg (90’6” total length).Emergency operation on 5167.5 kHz is shared with the Alaska-Fixed Service. This transceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical communications.

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.
