A shortwave radio receiver picks up from a wide range of frequencies around the world. It doesn't require an expensive antenna, in fact the external antenna I bought for mine is just a copper cable you stretch around different points on your roof or wall.
A portable short wave receiver may cost as low as $50. Major manufacturers of shortwave radios include Grundig, Eton and Sangean, although there are others.. If you are new to shortwave radio, it is best to check websites and other print publications, including The World Radio Guide, that have consumer and expert reviews on the sensitivity and selectivity of certain models.
Differences in Shortwave Radio Receivers
There are two types of tuning: analog and digital. Analog tuning and display are less expensive. It is usually placed on the shortwave radio in the form of a fine-tuning knob. Analog tuning and display is less accurate compared to digital tuning which is consequently, more expensive. The latest models of shortwave radios allow tuning via personal computer that ensures accuracy.
If you like to purchase a portable receiver, two things you have to
consider are the batteries and the extendable whip antenna. Reception
through portable radios is more critical but listening through it surely
is worthwhile when you are the on-the-go type. To add a more
interesting note on your hobby, make sure that your receiver has BFO or
any other similar circuitry that allows Morse code and SSB signal
decoding.
