Minimum TX bandwidth

Hello,

I am running a flow graph to test the TX of my LimeSDR. I am using the parameters shown on the flow graph and running GNUradio on a Linux PC. I have the bandwidth at 25kHz since I do not want to take up much of the amateur band. I am getting this error.

RuntimeError: Tx lpf(0.025 MHz) out of range 5-40 MHz and 50-130 MHz

What is the minimum bandwidth I can input to run GNUradio TX. I cannot find a specific bandwidth on the datasheet.

Ricardo

Clue is in the error message, tx low pass filter range from 5MHz to 130MHz

Hi,
What is the minimum bandwidth for LimeSDR mini 2?
