Enclosure Kit For The Genesis G3020 Transceiver

 

What you get in this kit is 1/16-inch aluminum parts for the top, bottom, front and rear panels for the enclosure itself, a length of aluminum angle sufficient to make four PCB support brackets, a classy aluminum knurled knob for the Band Center switch, and a sharp, uncut glossy photo print of the front panel displaying your call letters.

The print can and should be used as a drill template for the various holes in the front panel.

Any radio amateur who can build a G3020 can put this kit together using ordinary hand tools. A primary consideration is this: The vertical location of the PCB is absolutely fixed by the location of the four jacks for Key, Phones, In and Out. Use the same vertical dimension for the rear panel jack. Add circuit board brackets to fit.

The Kit

The right rear bracket goes on the corner of the circuit board.

 

The left rear bracket

goes inboard. Note the position of the binocular transformer and the paddle jack.

 

The brackets that attach the circuit board to the front panel use existing holes in the corners of the board, while the holes for the rear brackets must be drilled.

 

Heat buildup in this enclosure, if left tightly sealed, will quickly and certainly cause serious problems. Some means of ventilation MUST be provided. The manner in which ventilation is accomplished is to be decided by individual users, depending on anticipated needs and or tolerance of less attractive appearance.

Why Go To The Trouble?

Why did I bother to design a special enclosure for my G3020? Simply put, I did the design because...

I believe the Genesis G3020 Transceiver is a

fine piece of equipment, and that it should

be housed in an equally fine, attractive enclosure.


To house a the radio in anything less than a high-quality, made-to-order enclosure that looks as good as the radio operates diminishes the elegance of the radio.

Yes, there are other ways to do it that are less expensive (or maybe not), but most require living with either a too-large box or one that is too small that has to be cut down in some way. Both compromise the quality of the final result. In my opinion, either such option is not appropriate for the G3020.

Once the circuit board is attached to the front and rear panels, the installation and wiring of the panel-mounted components is a snap. Similarly, having ready access to both sides of the board facilitates servicing.

 

Ventilation

The Band Center switch I used in my G3020 is Radio Shack #275-1386. It costs only $2.99 and is more than adequate.

Basic Assembly

This shows the basic assembly and the gross dimensions of the enclosure. Note the front panel is stylishly inset approximately one-eighth of an inch. The rear panel is flush. Work so far consists of merely drilling eight holes and drilling and tapping eight others. All screws are 1/4-inch, 4-40 binding head.

PCB Brackets

Four simple L brackets hold the circuit board to the end panels, two on each end. The brackets are cut from a piece of 1/2-inch by 1/2-inch extruded aluminum angle  that is included in the kit. Each bracket is 1/4-inch wide. One leg of each of the brackets is cut to 1/4-inch in length so as to avoid crowding any of the components on the circuit board, especially near the front panel.
