MF SSB and HF SSB aircraft bands
| Band | Frequency Range |
|---|---|
| 405-525 kHz | MF band, used in some areas for NAVTEX on 490 kHz and/or 518 kHz. 500 kHz (600 meters) was the original CW Morse code calling frequency |
| 1600-2000 kHz | MF band, used in Europe and elsewhere (also used heavily for fishnet beacons) - overlaps with 1800-2000 kHz 160 meter amateur band |
| 2000-2300 kHz | MF 2 MHz marine band - USB voice calling/distress 2182 kHz, DSC calling/distress 2187.5 kHz - USCG no longer monitors 2182 kHz USB |
| 2450-2850 kHz | MF 2 MHz marine band |
| 4000-4063 kHz | 4 MHz fixed/mobile band, shared with marine for simplex purposes |
| 4063-4438 kHz | HF 4 MHz marine band - USB voice calling/distress 4125 kHz, DSC calling/distress 4207.5 kHz |
| 6200-6525 kHz | HF 6 MHz marine band - USB voice calling/distress 6215 kHz, DSC calling/distress 6312 kHz |
| 8000-8195 kHz | 8 MHz fixed/mobile band, shared with marine for simplex purposes |
| 8195-8815 kHz | HF 8 MHz marine band - USB voice calling/distress 8291 kHz, DSC calling/distress 8414.5 kHz |
| 12330-13200 kHz | HF 12 MHz marine band - USB voice calling/distress 12290 kHz, DSC calling/distress 12577 kHz |
| 16460-17360 kHz | HF 16 MHz/17 MHz marine band - USB voice calling/distress 16420 kHz, DSC calling/distress 16804.5 kHz |

| 25070-25121 kHz | HF 25 MHz marine band |
| 26145-26175 kHz | HF 26 MHz marine band |
| 26175-28000 kHz | Various CB-like marine allocations found in this region (maybe HF-marine radios stop at 27500 kHz or 27.5 MHz) |
