case and hardware set will give your unit that nice finished look and increase its resale value. These sturdy black instrument cases are supplied with neatly lettered front and rear panels, switch knobs, rubber feet and mounting screws.

While we believe that the Ramsey enclosure and knob option is a fine value for finishing off your Ramsey kit, we are happy to give you a couple of additional suggestions and our reasons for them. If your first goal is economy and rugged portability, you will find that the circuit board can be mounted nicely in a standard VHS videotape storage box, which also gives room for storing cables, a small homemade keyer, etc. The controls are easily mounted at one end of such a box. It may be necessary to cut away the molded posts which secure the tape itself. These storage boxes come in several styles, so pick one which truly looks practical as a project enclosure. To accomplish RF shielding, the most economical metal enclosure nicely suited for Ramsey amateur kit board is Radio Shack No. 270-253A. This metal utility cabinet can accommodate both a receiver, transmitter and amplifier board, plus speaker, with room for various refinements you might like to add.
