Hi Chris, Can you briefly explain in what exactly consists the Software PLL? All, I've been trying to set both Tx and Rx to the same frequency and sending a sinusoid to try to measure the frequency offset, but it does not seem to work... it looks like as both Tx and Rx are driven by the same clock

I did the records ok; I put the audio-X.dat in the same folder as fm_tx4.py, and I try to transmit in for example 32MHz; and in other USRP board I put the Basic RX, trying to receive in 160 MHz (32, 96 and 160 Mhz) but I don't receive anything. Maybe I choose wrongs frequencies to transmit (and rec
