| AM | Used to describe the Medium, Long and Short wave bands |
| Bandwidth control | Bandwidth control on a short-wave radio receiver allows you to control the selectivity of the receiver so that interference can be reduced considerably. |
| EON-traffic system | By utilising the RDS service "Enhanced Other Network" (EON) Listen to an RDS programme without missing news even from other networks. |
| FM | Used to describe the VHF wave band |
| Ionosphere | shortwave travel around the earth by bouncing between the earth and the ionosphere (The part of the earth's atmosphere that reflects shortwave back to the earth) |
| LCD | (Liquid Crystal Display) all of our digital radio's have LCD displays |
| Local DX Switch | DX stands for distance. This switch adjusts the sensitivity of the radio to improve reception of distant stations or prevent over loading of the radio by a very strong local transmitter. |
| Notch Filter | A notch filter removes a very narrow slice from a received signal. either from the radio frequency itself (RF notch) or from the audio output (audio notch) of the receiver |
| Narrow, Wide | With so many stations broadcast on adjacent frequencies, its is possible to adjust the signal bandwidth and sharpen the tuning to reduce unwanted noise |
| Pre-sets | This allows you to programme your favourite stations on you radio |
| PLL | (Phase Lock Loop) an Electronic circuit in digital radios that locks onto your chosen station to give clear drift free reception. |
| RDS | (Radio Data System) The LCD display on the radio will display the radio station name and depending on the model of radio, some program information as well |
| RF Gain | A Control that permits the sensitivity of the reciver to be continuously varied |
| SSB | (Single Sideband) Only essential if you want to listen to ham radio and utility stations. Single side band operation makes it possible to concentrate the full transmission energywith suppressed carrier noise |
| Scanning | This feature allows the receiver to automatically tune through a desired frequency range, stopping on all frequencies where a signal is present. |
| Selectivity | The ability of the receiver to select the station it is tuned to, from all the others close to it on the dial/display. |
| Sensitivity | The ability of a shortwave radio to repond to weak signals. It is measured in microvolts. The lower the measurement in microvolts, the fainter the signal the radio can receive. |
| Squelch | This quiets the receiver audio until the strength of the signal exceeds a desired level. |
| Synchronous detection | This feature is found on the Sony SW7600 SW100E and Grundig Satellite 800. It is a circuit that replaces the carrier in a received AM signal with with an internally generated replacement to reduce the effects of fading. |
| Varible Bandwidth Tuning | This is a circuit that allows the selectivity of a receiver to be continuously varied. |
| World Band | Another name for short wave |
