Good Day, We are able to receive FM signals using the USRP1 with WBXv3 50-2200 having a 750cm solid wire that serves as an antenna. We were wondering how to modify the generated GRC python code. We are planning on changing the center frequency automatically with an interval of 200MHz in a specified time. Thank you.
