I can’t imagine (and in fact never heard of) any such assertion that at one time in the past you could operate on the AM band with 100 watts! That’s just crazy talk! I am sure that should have said 100 milliwatts (for AM only; not FM), which is the same as today.
Sorry to say, I just don’t ever see the FCC allowing any power increases for unlicensed operation on either AM or FM (especially FM). The NAB and the big conglomerates would fight this tooth and nail if it ever even got to the point of being considered by the FCC.
I have written about this before. In my personal opinion, increasing the power limit for unlicensed operation would be foolhardy because it would quickly become a food fight for car dealers, real estate agents, religious organizations, etc. I don’t see a licensed LPAM service turning out any differently. Keep in mind that unless you live in rural Idaho, there are very few usable frequencies on either AM or FM in a given community, and those would be quickly snapped up by special interests. Most of the members of this board would not be among them.
With the technology we have today, the place for “low power broadcasting” is the Internet. ANYONE with an Internet connection can put a stream on the “air” and there is no licensing requirement. Anyway, in the future, radio as we know it may well cease to exist once ubiquitous wireless Internet connectivity becomes available.
For now– enjoy Part 15 operation as it is, and have fun maximizing your facilities to the limit that the laws of physics allow under the existing regulations. That’s my view!
