Channel Evaluation and Call (CHEC) system was developed at Defence Research Telecommunications Establishment to improve reliability of air-ground-air communications; it provides aircraft radio officer with continuous evaluations of number of frequency allocations from which he is able to choose optimum; system eliminates need for conventional time-consuming hunt-and-try techniques for making radio contact; extension of CHEC system could provide automatic selection of optimum communications channels.
