It's all about the Software

Did you ever adjust the RF gain on the Pluto? If yes is the antenna connected to the Rx antenna port?

Attach a charger to the second Pluto port. The Pluto is crying for more power. And USB 2.0 power delivery is very weak. Did you ever ask yourself why the designers put that second port there for more power?

A full size screen shot showing the problem is required. You are probably missing data that is required or have an invalid entry.

It has gain settings from a useless 0 (or even below with some adjustment curves) to over 40 dB. The optimum setting is typically about 20...

I'm not sure SDRC can be happy in a machine with only 2 Gigabytes of memory. Probably some of the added features have pushed it beyond what your tiny little system can support.

Post full size image of the main screen, and additional images of floating windows associated with SCRConsole.

Meanwhile, what bandwidth are you trying to use? What source? What sample rate? All that good stuff.

Which window was active? Click snapshot on the active window or else use alt prt-scn and Paint to capture the active window or prt-scn alone to capture everything.
