SF2010 2/01 is a standard for radio broadcast receivers that was developed by the Belling Lee company. It is a technical specification that outlines design and performance requirements for a range of radio broadcast receivers. The standard defines the characteristics of an optimal receiver including signal strength, sensitivity, selectivity, frequency stability, audio response, distortion, interference suppression, and more. Additionally, the standard helps to ensure interoperability between receivers. SF2010 2/01 is universally accepted as the standard and is mainly implemented in the UK, Ireland, the Netherlands and a few other countries.
