Chain search in a scanning receiver
 A method of searching for active signal frequencies from a plurality of frequency bands is disclosed. Bands of frequencies are defined by upper and lower limit frequencies. The bands are stored as chains in a chain memory. A controller searches for active signal frequencies by sequentially recalling each chain and searching the band of frequencies defined by the upper and lower limit frequencies. Active signal frequencies may be stored in a channel memory.
