Building a full SDR stack from source for LimeSDR

Rationale Generally speaking, building from source offers one key advantage: it is the only way to test the latest features offered by the community. Moreover, if you intend to develop or fix bugs (or even help the community fix bugs), you will need to have a working and up-to-date software environment. All in all, compiling LimeSDR’s software stack is fairly straight forward. It is barely a matter of getting the right cmake options. While we want to compile as many…

Cooling the LimeSDR (with IR pictures)

One thing that struck us as well as the community is the overall heat that is cumulating on the LimeSDR. Having worked with the Ettus B210, we were surprised of the 60°C shown in LimeSuite under no significant load. Some were concerned by the premature degradation of the board, but heat may also impact RF performances (chapter 4.4). As such, we decided to take action against what we considered could be a problem. This SDR contains three main chips: a Cypress FX3 CPU,…
