Below is a link to a 32-second clip of WGN (720 kHz, Chicago) recorded this morning using a cellphone app and mic near the speaker of a $35 Radio Shack receiver operating inside my home. My location is about 20 miles beyond their 150 µV/m groundwave contour.
It might give some idea about the listening quality to be expected for those conditions, in an area of fairly low r-f noise.
It don't sound too bad but after a while may give a little fatigue. No buzzing or anything like that. Now if we could get our part 15 AM stations to sound that way for at least a mile we'd have it made for AM. Nice going Rich.
That's just "normal" noise you get with a weaker signal. AM wouldn't be that bad if that's all it was.
Amazing you don't have all the electrical interference from A/C in your home..or at least in that location that makes AM not listenable in homes.
Did you have the power in your house turned off at the time?

No, all circuits were hot. Worse noise content was possible depending on the physical orientation of the receiver.
I did pick an orientation that produced the least noise, and fortunately the loopstick antenna in the radio was still pretty well favoring the reception of Chicago AM stations at that orientation.
