RADIO LISTENING GUIDE

LISTENING TO OTHERWORLD RADIO ON AM

Otherworld Radio will be coming to 1680 AM very soon! Until then please listen to our archived shows.

The amplitude modulation (AM) — aka medium wave (MW) — broadcast band ranges from 535 kilohertz (kHz) to 1720 kHz. Here is an affordable antenna to boost your AM reception (you don’t need to connect it to your radio, just place it close to your radio and experiment with different positions and angles — of the radio or antenna — to increase reception clarity).

SHORTWAVE LISTENING GUIDE — QUICK AND EASY

Shortwave (SW) aka high frequency (HF) broadcasts are able to travel great distances; this allows SW stations to broadcast to other countries, and even reach other continents all over the planet. The SW band extends from 3000 kilohertz (kHz) to 30000 kHz (expressed in megahertz this would be 3 MHz to 30 MHz; expressed in terms of radio wave length, 100 meters to 10 meters). A long length of insulated stranded copper wire (any kind of wire will work though) works as a great antenna for SW listening. The gauge of the wire is not important, but it should be suitable for the stress it will be under (outdoor antennas are under greater stress so a thicker [lower gauge] wire would be best) and practical for your needs (14 to 22 gauge is commonly used) — just string it up high, away from large solid obstacles, and connect it to your radio’s antenna with an alligator clip or attach a plug if your radio has an external antenna input. This kind of simple antenna is known as a monopole.

VLF = very low frequency; LF = low frequency; MF = medium frequency; HF = high frequency (aka shortwave); VHF = very high frequency; UHF = ultra high frequency; SHF = super high frequency; EHF = extremely high frequency (right click and open image in new tab to see bigger)

Shortwave (SW) stations use Universal Time Coordinated (UTC) — aka Coordinated Universal Time. Greenwich Mean Time and Zulu Time are the same as UTC and are used interchangeably. SW stations usually announce the time at the beginning of each hour. You can also figure out the time by tuning in to Atomic Time Station WWV — https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwv — You can hear this station best on 2,500 kHz, 5,000 kHz, or 10,000 kHz in the evening, and on 10,000 kHz, 15,000 kHz, 20,000 kHz, or 25,000 kHz in the daytime hours. You can also call 303-499-7111 to listen to this station.

FINDING STATIONS

SW and amplitude modulation aka mediumwave (AM or MW, respectively) frequencies are usually expressed in kilohertz (kHz). If the frequencies are expressed in megahertz (MHz) you can convert them to kHz by moving the decimal three spaces to the right (e.g., 5 MHz = 5000 kHz; 15.5 MHz = 15500 kHz).

The best way to find stations is to just start at 3000 kHz and start scanning up the band. You can keep a log of what you find at what times so you know where to look next time. You can also use https://shortwaveschedule.com/ to find stations to listen to, or you can order a physical copy of stations/schedules here: http://www.wrth.com/

If you are on a smartphone or tablet try using the Skywave Schedules app to listen to computer controlled shortwave radios all over the world!

SW stations broadcast on different frequencies to maximize their range. Remember that higher frequencies are usually the best in the daytime and lower frequencies tend to be the best at night.

Enjoy surfing the waves!
