High quality FR4 double sided 1oz copper, masked, and silk screened both sides. Dimensions: 1.8" x 1.3".

A fully opto-isolated interface between an Icom radios analog voltage band data output and the Antenna Switch Controller. The board is designed as a "daughter card" which plugs into the CD4028 socket of one or the other port of the controller. This board takes the place of all the components of one of the two decoders. It can be used as a stand-alone decoder as well!
