Want to bring your DMX/MMX/ZERO to the next level? Want to add to its durability while shielding its receiver from localized EMI and dissipate heat? CNC machined from a single 6061-T6 billet in the USA, this fits all 3 models of Preppcomm's finest products. The standard 3D printed lid fits this perfectly, and the fine engraving on the back displays the level of PATRIOT you are. No other company on the market offers a one-piece case, fully machined from one solid block of aluminum, let alone manufactured in the USA. ADD TO CART NOW to create the SUPERIOR QRP Rig/Decoder you will treasure forever and your buddies will keep trying to borrow. 

MMX Heavy Metal is a replacement for the bottom section of the plastic case your MMX, DMX-40, or MMX ZERO comes in. The lid stays the same. First, you remove the six screws from the metal case - they are different threaded than the screws that came with your product. Next, you simply remove six screws (two on the rear panel first, then four on the top four corners), lift out the electronics. Carefully insert the electronics into the MMX Heavy Metal, tilting down on left side. Attach the rear panel with the two metal screws, and then the top four corner screws. You're done! Enjoy!
