This is a holder for the HamSCI Grape 1 receiver circuit board.

The Grape 1 is used by volunteers to monitor shortwave time signal stations as part of academic projects that research the Earth's ionosphere. The HamSCI organization coordinates volunteers and distributes the collected data to researchers.

The Grape 1 circuit board snaps into the base of the holder. There are cutouts for the board's RF connectors, and a tall edge with holes for mounting power and audio connectors. The holes are small and will have to be drilled or reamed to the proper size for your connectors of choice.

A small boss in the bottom of the holder supports the board so components on that side don't touch the base, and two more bosses on the sides retain the board so it doesn't slip out.

Original was printed in PLA. Any reasonably rigid material should be adequate.
