So if I can paraphrase in layman terms if I can. If you can’t meet the ground/antenna rules for part 15:219 for AM than everything reverts into an AM version of FM where as you have to meet the field strength limits which I forgot the field strength for AM because we always hear about 15:239 for FM. However I’d think on the wire antenna it would be hard to go over the limit at the rated power of 92.5 mW on a Talking House 5.0 for an example. I think many apartment dwellers in high apartments probably meet field strength standards because it is going to be hard to get that signal outside of most apartments unless they don’t have any aluminum or lots of metal duct work or framing in them.
