4SQRP Club's QRPometer Case (retired kit but needed a case) by JimSheldon

Last crawled date: 3 years, 4 months ago

The 4 State QRP Club (4SQRP) once had a really nice kit for sale called the QRPometer. It's a SWR meter, Power meter with a built in 16 watt dummy load with a digital LCD readout. They have since retired the kit and it is no longer available but for those who have one, it was never sold with a case, and the internals were open to the elements.
A 3D printed case was requested and this is the result. Layout was done in Fusion 360 and the F3D file is included so it can be easily customized by those who use F360. The 4 corner mounting holes should be tapped 6-32 to match the screws used in the original kit but you will need to replace those screws with some slightly longer ones. The optimum length is 6-32 x 1.25" and with the tapped holes in the case and using the standoff hardware that came with the QRPometer kit, it will be solidly mounted to the case and the front panel will be flush with the top of the case. (See the photo).
The QRPometer was first provided with PC boards that had black colored silkscreen and later with green. I used a green one for better visible detail but both the black and green PCB versions have identical dimensions and this case will fit both. (A friend loaned me one of the early black PCB versions to make sure so it has actually been tested.)
