FT-950

Operating Manual

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 communications.

The FT-950 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 the [MENU] button to enter the Menu mode.

2.Rotate the [SELEC] knob to select “118 TGEN EMRGNCY.”

Advice: Press the [SELECT] knob to toggle the Menu item display between “118 TGEN” and “EMRGNCY”.

3.Rotate the [CLAR/VFO-B] knob to select “EnA (Enable).”

4.Press and hold in the [MENU] button for 2 seconds to save the new setting and exit to normal operation. Emergency communication on this spot frequency is now possible.

5.Press the [V/M] button, as necessary, to enter the Memory mode. Press the [MCH] button, then rotate the [CLAR/VFO-B] knob to select the emergency channel (“EUS”), which is found between channels “US5” and “01”).

Note:

The receive-mode CLARIFIER functions normally while using this frequency, but variation of the transmit frequency is not possible. Activation of “118 TGEN EMRGNCY” does not enable any other out-of-amateur-band capability on the transceiver. The full specifications of the FT-950 are not necessarily guaranteed on this frequency, but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency communication.

If you wish to disable operation capability on the Alaska Emergency Frequency, repeat the above procedures, but set “118 TGEN EMRGNCY” to “diS” in step 3.

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.
