International Shortwave
Broadcast Bands The
International Shortwave Bands and Frequencies: 11
meters – 25.67–26.10 MHz – Very little broadcasting activity in
this band. Day reception tends to be poor, night reception nonexistent.
This band could be used for daytime 'single hop' regional coverage, but
very few broadcast transmitters and antennas function in this band. Not to
be confused with the Citizen's
Band 11-meter allocation, which in most
countries runs from 26.965 MHz to 27.405 MHz.
13 meters – 21.45–21.50 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 – 18.90–19.02 MHz – Seldom used. 16 meters – 17.48–17.90 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. Listen on 15.000mhz. 22 meters – 13.57–13.87 MHz – Similar to 19 meters; best in summer. 25 meters – 11.50–12.05 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. WWV can usually be heard well on 10.000mhz. Set your clock! 41 meters – 7100–7350 kHz – Reception varies by region – reasonably good night reception, but few transmitters in this band are targeted to North America. CHU Canada time station on 7.335mhz. You'll also hear lots of U.S Amateur Radio Operators, mostly LSB mode. 49 meters – 5900–6300 kHz – Good year-round night band; daytime reception is lacking. 60 meters – 4750–5100 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, not widely received in the Americas. (3900 to 4000kHz U.S Amateur Radio Frequencies usually LSB single sideband mode) 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. Not technically a shortwave band; resides in the upper reaches of the medium wave band. Tuning in between these bands above can be an adventure, with many government stations, pirate broadcasts, long range military aircraft, and commercial planes, ships and shore stations. The Ham (Amateur Radio)
bands.
Mixed between the shortwave bands above are many hf ham radio bands where you can hear ham radio operators from all over the world conversing back and forth. You can sometimes hear emergency communications going on from all parts of the world. During major disasters, ham radio operators are some of the first to get the needed communications out to the world when local power goes down. The ham radio bands can be a
very interesting source of shortwave listening at other times also.
A receiver that has the ssb mode is usually required. The Ham Radio HF bands in a nutshell:
(Helpful tuning hints) Tune the 160 thru 40 meter bands in the lower side band mode (lsb) for voice. Tune the 20 meter thru 10 meter bands in the upper side band (usb) mode for voice. See below for 60 meter mode information. The new 60 meter ham band:
Example 5368kHz = 5.368Mhz) (Communications and good reception on the hf bands is highly dependent on the condition of the ionosphere, your antenna, your location, the time of day and the quality of your receiver) NOTES: You can build your own shortwave antennas!.....click here for shortwave antenna plans!
