So, I have a project which transmits multicarrier WBFM signals using gnuradio and LimeSDR on a M2 OSX Mac. The LimeSDR feeds into an amplifier, and the outcome is a signal which meets power needs I have from the setup.
I recently bought a LimeSDR Mini 2, and swapping it in place of the LimeSDR, the power level I see (for the same ‘gain’ setting) is much lower.
I hadn’t updated my gnuradio setup, and it recognized the LimeSDR Mini 2 without any changes, so I assumed I will get similar performance. What am I missing?
- Do I need to update the software on the Mac?
- Do I need to perform some sort of calibration? I assume the LimeSDR (& Mini) both do some kind of calibration everytime I launch the gnuradio program.
- Anything else I may be missing?
