No I don't see the tone/spike. Infact, even with my own code, if I just tx and connect the source USRP to uhd_fft.py file, I dont find any peak at the frequency range.
Surely, this clears that the sink USRP could not be transmitting, but then why do I get similar repeated samples in my source USRP 40-60 seconds even later after my tx flowgraph has been executed. I am not sure, but is because my rx flowgraph uses a head block, so the required number of samples get filled, and the remaining, are filled in the buffer of the USRP1, that when I run my rx flowgraph again, I get those samples... (doesn't make sense, i think to have such a functionality, so maybe this is not the case). Please help me find out the issue, as I keep getting the same samples printed on my matplotlib graph even after tx has been executed UB Marcus D. Leech wrote: > > OK, so heres an idea.
