For the reception, if your radio is known good - the GND and the antenna.
For the noise, if you do not live next to the power line, see if you have a DCDC converters (any modern electronics, wallwarts, wall chargers, CCFL/LED lights so on, so foth) nearby or in close vicinity. Or the neighbor across the wall with all that.
One way of mitigating (but not necessarily eliminating) this problem is an X-cap across the power line inside the radio (0.1uF - 1uF, X-rated for 127VAC at least). Or a box with a good AC power filter inside (like those by Schaffner).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
