This frequency is only to be used when the immediatesafety of human life and/or property are threatened, and is never to be used for routinecommunications.The FT-817 includes the capability for transmission and reception on 5167.5 kHz undersuch emergency conditions via the Menu system. To activate this feature:1. Press and hold in the key for one second to activate the Menu mode.2. Rotate the knob to select Menu #28 (EMERGENCY).3. Rotate the knob to select “ON.”4.

Activation of Menu #28 does not enableany other out-of-amateur-band capability on the transceiver. The full specifications of theFT-817 are not necessarily guaranteed on this frequency, but power output and receiversensitivity should be fully satisfactory for the purpose of emergency communication.If you wish to disable operation on the Alaska Emergency Frequency, repeat the proceduredetailed above, but set Menu #28 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 trans-ceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical communi-cations.OPERATION ON ALASKA EMERGENCY FREQUENCY: 5167.5 KHZ (U.S. VERSION ONLY)
