Antennas can help too? with AM many homes are nosiy at RF
IMO&E PC's Modern TV's and anything else with a switch-mode PSU, will generate quiet a lot of RFI/EMI. which a meer intrenal antenna WILL pick up.
A random wire up highish outside, feeding into a 'low-noise' down lead - some fig 8. wire, or some 300 ohm TV ribbon, looped to stop rain entering yr home, and earthed to a real RF ground, will be a lot better than just the ferrite rod on the back.
if you add a tapped coil and a vane cap you can tune the wire so it 'thinks' it is from 600 metres to 200 or so metres long. this alolowers the bandwidth of the antenna system and lowers nosie even more, it also increases gain.
If the earth is accessible under the run of yr wire up in the air, you could run an in-ground radial back to earth of the same length as yr random wire.
Even an exterior remotely tuned loop, using a varactor, is possible, you put the loop made from rainbow/ribbon inside some EV stable pipe in circle and yr done, maaate.
