I’m trying to get a basic RX setup going in GR with the LimeSDR mini 2.0 but am unable to read any signals. I’ve tried configuring as per the wiki below and I’ve also tried without the low pass filter. I’m targeting 100MHz and I expected to see some activity here for commercial FM stations, but the graphs are completely flat. An almost identical setup using a HackRF worked fine, even without the low pass filter.

Lime seems to work fine in gqrx, but I get nothing in GR. Any ideas what I’m missing here?

Which version of LimeSuite are you using?

It could be that you have the wrong antenna selected.
