[AMRadio] Low powered FM

[Jeff/W5OMR]

It maybe off-topic, but I'm sure someone has the answer, here.

I'm curious about something... Low-powered FM broadcast.  Somewhere in the FCC
Rules and Regs, it says that anyone can transmit anything, as long as it's below
(_blank_) amount of milliwatts, and the antenna is less than (_blank_) feet, or
has than (_blank_) ERP.  Can someone fill in the blanks?

Implementations are endless.  Remote keying of Transmitter, and remote listening
of receiver?
How much quality audio could you put over say, 100kc of bandwidth into your
speech-amp, and then filter it out with a band-pass filter from say 30cycles to
around 3kc's, in the speech-amp?

I'm thinking that with a line input, and filtering thereafter, that some "solid"
audio would be 'flat' from the bottom end of the band-pass filter to the top.

Personally, I wouldn't want to get too far away from the main transmitter, just
in case something goes horribly wrong, but within the same house would be cool.

Keying a small FM kit transmitter would be as simple as receiving enough signal
at the FM receiver to drive a transistor (like a 2N3904) to key the transmitter
(or close a relay to handle more current).  As simple as flipping a switch, at
the LP-FM xmtr

but, what are the limits?
