Agree. The link below leads to an example of the noise on a weak,
daytime AM signal received from WBBM, Chicago (50 kW non-D on 780 kHz)
on a Sony ICF-2002 with its internal antenna, indoors in an urban
location. The groundwave path from WBBM to the receiver is about 225
miles in length. According to the FCC propagation curves, WBBM has a
daytime groundwave field intensity of about 0.14 mV/m for this path
(probably less in an urban area).

The noise in this MP3 clip maybe is tolerable for short-term
listening, or if there is nothing better receivable.

The recording was made Jan 10, 2009 at about 12:30 pm CST.
