Kalibrate is a program I wrote that scans GSM frequency bands and looks for base stations. It also caculates the offset between your local oscillator and a GSM base station's oscillator. (Kalibrate was originally just designed to calculate the oscillator offset. It's just convenient for kal to a

Hi Venkat, A couple of things to try: Try removing the tb.stop() call, lock will stop the flowgraph anyway. You may need to 'disconnect' (essentially undo all the connect calls) the path before recreating it. In the first instance try the disconnect_all() method, but from memory that had some issu

Hello All, I am having some difficulties implementing a cognitive receiver program that involves dynamically reconfiguring the USRP between sensing the spectrum and acting as a receiver based on the results of the spectrum sensing. The program I am developing is mostly based on the usrp_spectrum_s
