Operation On Alaska Emergency Frequency - Yaesu FT-847 Operating Manual

Operation on Alaska Emergency Frequency: 5167.5 kHz
Section 97.401(d) of the regulations governing ama-
teur 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 communications.
The FT-847 includes the capability for transmis-
sion and reception on 5167.5 kHz under such emer-
gency conditions via the Menu system. To activate
this feature:
•
Press the [MENU] button to activate the Menu
mode of operation.
‚
Rotate the SUB-TUNE knob to select Menu #40
("5167KHZ").
ƒ
Rotate the MEM/VFO CH knob to select "ON"
for this frequency.
„
Press the [MENU] key to exit the Menu mode.
Emergency communication on this spot frequency
is now possible:
Press the [BAND] keys, as necessary, to locate
the Emergency Channel, which will be located
between the 3.5 MHz and 7 MHz bands.

mally while using this frequency, but variation of
the transmit frequency is not possible. Activation
of Menu #40 does not enable any other out-of-ama-
teur-band capability on the transceiver. The full
specifications of the FT-847 are not necessarily
guaranteed on this frequency, but power output and
receiver sensitivity should be fully satisfactory for
the purpose of emergency communication.
To return to normal transceiver operation, repeat
the procedure detailed above, but set Menu #40 to
ƒ
"OFF" in step of the procedure.
In an emergency, note that a half-wave dipole cut
for this frequency should be approximately 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.
