When Two become One: QubeDX v3
After I’ve built the QubeDX for the higher bands (20 to 10m) and it’s little brother, the QubeDX S for the lower bands, I’ve realized that it would make more sense to combine both cubes into one. This time I wanted it as compact as possible so I went for the footprint of the QubeDX S but added 30mm in height.
The final version now consists of:
- QRPLabs QDX 5W digital transceiver kit (high band version)
- QRPLabs QDX 5W digital transceiver kit (low band version)
- Raspberry Pi 5 with active cooling + NVMe SSD
- two buck converters
The Result
The following pictures show the finished setup:
