A {{w|Broadcasting|broadcast}} {{w|radio receiver}} (often called simply ''radio'') is an electronic device for receiving and listening to {{w|radio program|radio programming}} and has to be {{w|Tuner (radio)|tuned}} to a particular {{w|frequency}} to listen to the desired program. Frequency is measured in the unit of {{w|hertz}} or its {{w|Metric prefix|multiplies}}, in this example in megahertz. 1.618 MHz is located in the part of {{w|High frequency|HF}} (high frequency) range of the {{w|electromagnetic spectrum}} assigned (in the USA {{w|Frequency plan|band plan}}) to broadcasting, however not aligned to actual station assignments; the closest assignment is 1.620 MHz (1620 kHz) for {{w|WDHP}} station in {{w|Frederiksted, U.S. Virgin Islands}}. Due to inaccuracies involved with tuning and the 10 kHz {{w|channel spacing}} of American {{w|AM broadcasting|AM radio broadcasting}}, setting a real radio receiver to exactly 1618 kHz will allow listening to the mentioned station, as well as a few others which have nearby frequencies allocated, maybe with some distortion.
 
 
This is a pun referring to the {{w|golden ratio}}, being an {{w|irrational number}} of approximately 1.618 and to the {{w|golden spiral}}.
