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-857 includes 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-857 are 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.
