NOVEXCOMM has a 19" wide 3U height rack panel mount and tray assembly with hold-down kit for the radio and the power supply is bolted to the tray.
PHOTO DESCRIPTIONS:
2 of them show the DX-R8T in a shack rack; so pay no attention to cables, etc. this is the image the ham sent back to us and frankly it looks best on the slant view since the face-on shot washes out the screen.
The drawing shows the dimensions of the front panel; bet you knew that!
We know that you are aware the radios don't come with it; but we just have to say that for compliance!
When in doubt Google us up and look for more answers; QRZ shows me as WB6SLC Bob Burchett
