This discussion has led me to reconsider my use of AM. You get more range, but definitely more noise, and broadcasting after dark is effectively useless (my range shrinks down to 1 to 2 subdivision blocks).
FM isn’t nearly as variable, and with daylight here north of the 49th parallel shrinking to 8 hours or less, FM performs much better 67% of the time (admittedly, we do have an advantage here in Canada with, as I’ve stated previously, allowable field strength being 4 times greater than in the U.S.).
So maybe I’ll drag out the old Decade, and try to put it up as high as possible and see what happens.
[Another possible advantage of FM over AM not discussed here – a 100mw AM signal close to your house will likely overload the front ends of most receivers that you have – I even have a highly regarded Panasonic shortwave receiver that is greatly affected. A puny FM signal doesn’t affect anything at all – the reason you get the range that you do is the far greater sensitivity of FM receivers in general.]
