40 A GENERAL GUIDE T O SCANNING Recept ion of th e frequenci es covered by your scann er is m a inly “l ine- of- sight.” That means you usua lly cannot hear stat ions that are beyond the hor i z on.
41 Chan- nel No. Frequency C han- nel No. Frequency Ship Shore Ship Shor e Birdie Fr e quencies Every sc anner has birdi e freq uencies. Bi rdie s are signal s c reated i n- side the scanner ’s rece iver. Th ese oper atin g frequenc i es might inter- fere wi th br oadcasts on t he same freque ncies.
42 To fin d the birdi es in your partic ular scanner , begin by di sconnect ing the anten na and moving it away fr om the scan ner. Make sure that no other nearby radi os or TVs ar e t urned on near the sca nner. Use the sear ch funct ion to sear ch every fr equen cy range f r om it s lowest to the highe st fre quency.
