Here follows a list of the shortwave broadcasting bands, modification of the content found on Wikipedia.
Most international broadcasters use amplitude modulation with a stepping of 5 kHz between channels; a few use single sideband modulation.
- 11 meters – 25.670–26.100 MHz – Very little broadcasting activity in this band. Day reception tends to be poor, night reception nonexistent.
- 13 meters – 21.450–21.850 MHz – Somewhat shaky day reception, very little night. Similar case to 11 metres, but long distance daytime broadcasting keeps this band humming in the Asia-Pacific region.
- 15 meters – 18.900–19.020 MHz – Seldom used.
- 16 meters – 17.480–17.900 MHz – Day reception good, night reception varies seasonally, with summer being the best.
- 19 meters –15.00–15.825 MHz – Day reception good, night reception variable, best during summer. Time stations such as WWV are clustered around 15 MHz.
- 22 meters – 13.57–13.87 MHz – Similar to 19 meters; best in summer.
- 25 meters – 11.50–12.16 MHz – Generally best during summer; said to be ideal during the period before and after sunset.
- 31 meters – 9250–9995 kHz – Good year-round night band; seasonal during the day, with best reception in winter. Time stations are clustered around 10 MHz.
- 41 meters – 7100–7600 kHz – Reception varies by region – reasonably good night reception.
- 49 meters – 5800–6300 kHz – Good year-round night band; daytime reception is lacking.
- 60 meters – 4400–5100 kHz – Mostly used locally in tropical regions, though usable at night. Time stations are clustered around 5000 kHz.
- 75 meters – 3900–4050 kHz – Mostly used in Eastern Hemisphere.
- 90 meters – 3200–3400 kHz – Mostly used locally in tropical regions, with limited long-distance reception at night.
- 120 meters – 2300–2495 kHz – Mostly used locally in tropical regions, with time stations clustered around 2500 kHz.
