As much as I hate to say this, there is a gain difference between the versions 3.7.6-1 and the current version 18.104.22.168 using Ubuntu 17.10. I can take my LimeSDR on the latest release and try to tune the 80/75m band (3.5 MHz to 3.99 MHz) at night and it’s deaf. I can go back to 3.7.6-1 or use SDRConsole V3.0 on my Windows machine and the LimeSDR looks great tuning in those same bands - I’m seeing signals and the receive activity is correct. the latest SDRAngel version makes my LimeSDR seem ‘deaf’ no matter that I’m setting the gain controls to maximum.
This is disappointing…SDRAngel was my ‘go to’ application for receive and transmit for the Lime. I can limp along with 3.7.6-1 forever, but the new features (like the headless design that’s emerging) will not be in that version. Despite what the Lime Team has told you how to handle calibration and gain settings, there’s something wrong with the latest release of SDRAngel. Even with the latest firmware installed using LimeUtil --update and seeing that the latest firmware is installed in LimeSuite makes no difference for the operation - the Lime still seems deaf. Yet I can take it across the room, plug it into SDRConsole V3.0 and it works great for receive.
EDIT: The latest LimeSuite (within the past three days - November 25th to 28th) was compiled with the latest release of SDRAngel, so i’m using the latest LimeSuite and programmed by LimeSDR using LimeUtil --update and the latest firmware was programmed into the Lime - - confirmed by reviewing the ‘INFO’ button within LimeSuite.
