Shortwave And Ham Radio Bands

My grandfather’s old TRANS-OCEANIC shortwave radio (with tubes) still works great

‘Shortwave Radio’ (and HAM Radio) listening can be an enjoyable hobby – even while only listening to communications from near and afar over the airwaves. Not only is shortwave radio ‘listening’ a hobby for some, it can also provide information input during a time of disaster. While transmitting requires a license, listening is free.

The span of frequencies which are used for shortwave broadcasts and for HAM radio are split into ‘bands’. They’re sometimes referred to as ‘meter bands’, as in the 40 meter band, the 31 meter band, the 20 meter band, and so on…

The following is a list of the various ‘x’ meter bands, their associated frequencies, and a general description of what you might hear.


 
Depending on your specific shortwave radio, you will be able to receive local and international broadcasts as well as some (or all) of the amateur radio (Ham radio) bands. The allocated frequency bands generally have their own characteristics regarding the best time of day for reception (day or night).

Your shortwave radio might already list some of these bands on the front panel or listed in it’s manual. The information is also readily available on the internet from many sources.

By the way, the bands themselves (usually represented in meters) is the result of the width (crest to crest) of the signal’s wavelength. Picture a sine wave. For example the 31 meter band (filled with international broadcasts) is actually getting to your radio antenna by way of an ‘invisible’ wavelength of about 31 meters from one crest to another of its sinusoidal wave (that’s about 100 feet!).

To add one thing… If you want to get a radio and listen to the amateur bands, mostly all of HAMs use USB (Upper Side Band) or LSB (Lower Side Band). Mostly all listening short wave commercial radios don’t have SSB (Single Side Band) capabilities and will only receive AM broadcast (Amplitude Modulation) on 160 to 10 meters. Listening to either USB or LSB on a receiver that only has AM will sound something like a muffled noise.

Mostly all short wave broadcast stations are high power and transmit AM. AM transmissions take 3X the power of either a LSB or USB transmission to reach the same distance, thus ham radio operators mostly use this mode.

So if you’re looking for a shortwave radio, it’s best if it also receives SSB (Single Side Band).
