Saturday, June 29, 2024, Alaska Emergency Frequency Test

The last Saturday of each month, at 1000 local time, Department of Homeland Security (DHS) Auxiliary Station NNAØLP hosts a test of the Alaska Emergency Frequency on 5167.5 kHz.

Use only upper sideband USB (J3E or R3E).

Continuous Wave CW (A1A) and digital modes (F1B, J2B, etc.) are not authorized on this frequency.

Maximum power is 150 watts PEP.  There are no restrictions on types of antennas.

NOTE:  Government stations often use procedures taken from the United States Coast Guard (USCG) Radiotelephone Handbook, for example USCG Force Readiness Command (FORCECOM) CGTTP 6-01.1B, available on-line:

For signal reports, select one descriptor from the Signal Strength column, and one descriptor from the Readability column (see attached).

Each month, a summary report regarding this test is sent to the State of Alaska Emergency Operations Center (SEOC) and Federal Emergency Management Agency (FEMA) Region X staff are copied in.

Thanks very much,
