Subject: | Re: [Discuss-gnuradio] USRP IQ channels flipping during packettransmission |

I have also noticed the "flipping" , but not when transmitting only when restarting, the signal flips 90 degree.but this only happens when using the subdev, when using gr.sig_source_c thisdoesn't happen. I couldn't see why this only happens with subdev.
I had similar problems during receive. It appears that one I or Q sample was getting lost so the remaining I and Q samples appeared to be reversed. The problem only occurred when I was using usrp._read_fpga_reg() to poll the rssi register.
