i bought my limesdr a while ago directly from crowd supply, i never could get tx to work reliably so i set it aside for a while. I’m attempting to get it working again and figured i’d ask here for some advice.
Setup:
-Windows 10
-limesdr mini
-cheap 5 watt PA (have tried without it)
-sdrConsole v3 (have also tried sdrangel)
Symptoms:
-sdrconsole will tx once successfully per boot up (tx verified with rtlsdr)
-LimeQuckTest fails with result found at bottom of post
-several missing components (see images below)(i know that r67 is supposed to be there but am not sure about the others)
