Within a radio frequency (RF) communications system (200) having a plurality of transceivers (10) operating at various frequencies (F1-FN) within a predetermined range, a method (700-722) and apparatus (600) for selecting an operating frequency from within said range for use by communications equipment (10) commencing operation within said system (200). Said method and apparatus comprising apparatus and method steps whereby the communications equipment (10) scans (at 706), from its intended location of operation, a set of frequencies (F1-FN) within said range, stores (at 708-714) a table of information (800) corresponding to signals (300) sensed during said scanning, evaluates (at 716) the stored information to determine (at 718) a number of interference sources associated with each scanned frequency, and selects (at 722) that frequency from within the range having the least number of associated interference sources.
