Shortwave Radio – Which one is the Best?
By Avery Parker
A shortwave radio is a receiver that picks up from a wide range of frequencies across the globe. A basic unit may cost as low as $100. Major manufacturers of shortwave radios include Sony, Grundig and Ten-Tec among others. If you are new with the hobby, it is best to check websites and other print publications that have consumer and expert reviews on the sensitivity and selectivity of a certain model. Shortwave radios may differ from each other in terms of the number of bands and modes they cover, audio and tuning capabilities, power options, antenna and other physical characteristics. Other than that, some hobbyists in search for shortwave radios prefer vintage models for that nostalgic feel in it. Vintage shortwave radios may be purchased through online and print catalogs as well as auction sites such as Ebay. Other than that, hobbyists also choose their shortwave radio based on its physical features. There are some who like it big and others who like it portable. New models today are waterproof and have backlight. Most importantly, buyers should choose shortwave radios that can receive shortwave frequencies and standard broadcast radio frequencies. It has to at least cover 100 Hz to 30 Hz which includes international broadcasts as well as government and commercial frequency bands. Another thing to consider is the type of tuning a certain unit can offer. This will affect the radio’s access to signals while the display should determine if you were able to tune it accurately. 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 can even allow tuning via personal computer that ensures accuracy. You may also need to check the options you have for audio output. Basic shortwave radios merely have a built-in speaker or a mono-earphone jack. Opt for an earphone jack for better connectivity with external speakers, headphones and other audio output systems. Unfortunately, most shortwave radios only have slots for replaceable batteries. There are a few high-end finds that utilize DC power jack adapters. There are also emergency radios that have built-in power generators. As for antennas, for a shortwave radio it's important that it at least has a telescoping rod antenna or a built-in antenna. If you are willing to pay more for the device, look for a model that has an external jack or connectivity point for a secondary antenna. This allows better reception of signals to make your hobby more enjoyable than ever. If you like to purchase a portable receiver, two things you have to consider are the batteries and the extendable whip antenna. Reception on portable radios may not be as sensitive but listening through it surely is worthwhile when you are an 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.
