The conventional method of channel selection is via a multiway switch connected to a microprocessor which strobes the connections to establish the switch position selected. The number of connections required (N) is related to the number of switch positions (M) by the following relationship: M=2(N, or alternatively for N: N = log (M) / log (2) As an example for a typical 16 channel radio 4 con- nections are necessary.
