Hello,

The LMS7002M is specified for 100 kHz to 3.8 GHz range, but the LimeSDR mini has been designed for 10 MHz as lower frequency range, something that one (as me) may discovers after purchasing the board.

This optimitizations were threated for the LimeSDR board, not for the mini board as far as I know.  
For LimeSDR this page

suggests to remove MN18 inductors. For the LimeSDR Mini should be MN20.

But what about the output TX channel ?

Could you please suggest the required modifications to optimize TX/RX near the 100 kHz range ?

Thanks.
