13 3 OPERA TION The IC-PW1/EURO uses CI-V frequency data for automatic selection of the operating band. Program the exciter ’ s address to use this capability as follows: For non-Icom exciters, the IC-PW1/EURO cannot be controlled using the CI-V function, so this set- ting is not necessary . For transceivers which have multiple antenna con- necto ...
