Thanks for all the info, I think I am starting to wrap my head around all of this. So I did some more digging and have found some discussions on Transmitter LO leakage (LOL) that suggest creating a cancellation signal by applying dc offsets to the transmitters inputs. By doing this, would this mean that I would need to set up I and Q signal sources in GNU Radio companion that are always on and have to correct dc offset to cancel the LOL signal, or can I apply dc offsets to my signals that I want to be transmitted and whenever I turn them on the LOL signal will be cancelled out?

Best Regards, Jerrid Plymale Just to get some perspective, those levels are about 6dB *below* the limits of CFR 47 Part 15 for *radiated* power at *3M* from the box. Granted, inconvenient and a pain.

If you transmit all 0's with the gain turned all the way down, what strength do you see coming from the radio on the carrier? Brian
