The problem with P15 Fm is that the range, by definition, is useless. If P15
for FM was 100 milliwatts, *that* would be useful, but that just ain't so.
Someone here calculated it out to be some ludicrous number in the
NANOwatt range:
In the real world, that's useless for anything beyond about arm's length.
To be 100% legal with the P15 FM rules, your signal would only have a radius
of about 100' on a very clear frequency to a good receiver, direct
line-of-sight.
