Interference from radio noise remains a big problem... and it's tricky enough that the FCC wants your help understanding the issue in the first place. The agency has put out a call for public input that should not only determine the scale of radio noise problems, but design the studies needed to measure them. It wants to identify the main sources of this noise, where it's most likely to happen and whether it varies based on time. It's particularly concerned about "incidental" noise from devices that aren't meant to emit radio frequencies, like motors or power lines.
