Short wave reception
Your radio can receive signals in a number of frequency bands. It does not take long to get
used to tuning to FM and MW stations, since these stations are always at the same places
on the tuning scale because they broadcast at fixed wavelengths and frequencies.
Unfortunately, this is not always the case with short wave stations. Due to atmospheric
conditions, short wave stations must frequently broadcast on different wavelengths. Most
short wave bands are available all over the world and can be used by international
broadcasters. At present these are the only wavelengths which provide listeners with direct
reception over long distances. For this reason, short wave frequencies are not only used by
radio stations, but also by other users such as amateur radio enthusiasts, shipping, aircraft
and radio navigation systems.
If you want to listen to a particular SW station, you need to know the precise frequency and
wavelength. Many short wave stations will send you broadcasting schedules which give you
the information you need. You can also download the information from the Internet.
