Hello Rahul, Thank you for working through the setup with me. The XCVR2450 daughterboard can only tune as low as 2.4GHz so is unable to receive broadcast FM, which would use the Wide Band FM Receive block, at 98 MHz. You can try observing WiFi signals at 2.437 MHz as a pretty reliable test signal. You should also check what antenna you have connected and make sure it is appropriate for the frequencies you wish to receive.
