MF/HF SSB CHANNELS AND FREQUENCIES
Few, if any, Coast Stations monitor all the SSB Calling and Distress frequencies all the time. It is therefore
necessary to consult the Admiralty List of Radio Signals (ALRS), Volume 1, 1997 (Part 1 for Europe, Africa
and Asia [excluding the Philippine islands and Indonesia]; Part 2 for Philippine islands, Indonesia,Australasia, the Americas, Greenland, and Iceland). These books list all the Coast Stations, and their details
of times of working, frequencies monitored, etc.Call, Answer, and DISTRESS Frequencies Where a Coast Station uses frequencies from a band of frequencies, the 'Call, Answer and DISTRESS' frequency in that band is as follows:Band Channel Number Ship's Transmit Frequency.
MF:1. 2 MHz Band No channel numbers 2 182 kHz (Simplex) using
allocated in this band. Class of Emission H3E(When 2 182 kHz is in use for a Distress situation, 2 191 kHz is brought into use as a substitute 'Call,
Answer and Distress frequency.)
J3E Class of Emission:
See Appendix 5 for (Duplex - ships' transmit
HF: Receive frequencies [carrier] frequencies:)
and full details:2. 4 MHz Band Channel 421 4 125 kHz
3. 6 MHz Band Channel 606 6 215 kHz
4. 8 MHz Band* Channel 821 8 255 kHz
5. 12 MHz Band Channel 1221 12 290 kHz
6. 16 MHz Band Channel 1621 16 420 kHz
7. 18 MHz Band Channel 1806 18 795 kHz
8. 22 MHz Band Channel 2221 22 060 kHz
9. 25 MHz Band Channel 2510 25 097 kHz *Additional DISTRESS Frequency
The above frequencies, except for the 8 MHz Band frequency, are the only SSB frequencies to be used for
Calling and DISTRESS purposes. In the 8 MHz Band, the use of Channel 833, namely 8 291 kHz, is the8 MHz band frequency exclusively reserved for Distress and Safety traffic by the GMDSS (Global Maritime
Distress and Safety System) involving the use of COSPAS and INMARSAT satellites. Working and Inter Ship Frequencies
See the following lists of all the SSB frequency bands and their channel numbers and the channel frequencies. Typically a ship's transmit frequency used to a Coast Station, as Working Channels/frequencies are listed below. The Coast Station will tell the ship's operator what frequency to tune the
vessel's receiver to (i.e. the Coast Station's transmit frequency).
